Full textINTRODUCTION: Although Selective Serotonin Reuptake Inhibitors (SSRIs) are the first-line Posttraumatic Stress Disorder (PTSD) treatments their mechanism of action is unclear, but possibly improvement of stress resilience is involved. As serotonin (5HT) helps regulate stress responses in other anxiety disorders, the acute tryptophan depletion (aTD) technique was used to lower brain 5HT in SSRSs-remitted PTSD patients. METHODS: Ten patients with PTSD (Mini-International Neuropsychiatric Interview diagnosed) who had made a full recovery on SSRIs (Clinical Global Impressions Improvement Scale 1-2 for at least 3 months) were enrolled in the experiment. Patients were tested on 2 separate occasions a week apart - each session they received a drink containing large neutral amino acids either with (Sham Depletion [SD]; control day) or no tryptophan (aTD day). Self reports of anxiety and mood, as well as cardiovascular measures, were obtained throughout the tests. At 5.5 hours after the drink subjects were reexposed to their trauma using a modification of Pitmans imagery guided method. RESULTS: These procedures provoked elevated ratings on both days, with significantly more marked responses on the aTD day according to Visual Analogue Scales (aTD 47.57 [21.75] -v- SD 20.71 [18.4]; p=0.006), Davidson Trauma Scale (29.4 [12.7] -v- 15.7 [7.79]; p=0.001), Spielberger State Anxiety Inventory (28.9 [11.03] -v- 18.5 [10.13]; p=0.066, and Profile of Mood States (p<0.001). CONCLUSIONS: These data are the first to show that 5HT depletion worsens the subjective responses to reliving traumatic memories in PTSD and suggest that that SSRI-induced increases in 5HT function restrains PTSD symptoms, especially under provocation, i.e. 5HT helps mediate resilience to stress. As well as giving insights into how SSRIs work in PTSD, these data may also offer a translational approach to potential new treatments for this disorder

Full textThe hypothalamus is a diencephalic portion located around the third ventricle below the hypothalamic sulcus, limited by the optic chiasm, and by the mammillary bodies, acting as a center that integrates behavioral and homeostatic functions. Serotonin is a neurotransmitter produced in limited sites in the midbrain and brain stem, but is distributed throughout the central nervous system and has many functions, acting through specific receptors that are also distributed throughout the nervous system. Using immunohistochemical techniques, the aim of this study was to delineate the hypothalamic nuclei of the marmoset (Callithrix jacchus) and study the distribution of serotonin transporter and serotonin receptors in the hypothalamus of this species. We used the Nissl method to determine the cytoarchitecture of the hypothalamic nuclei, and immunohistochemistry to reveal the presence of NeuN as a method to determine the contours of the hypothalamic nuclei. As a result, we found serotonin containing fibers and terminals throughout the rostrocaudal extent of the hypothalamus, more concentrated in some nuclei, and even absent in some. Like serotonin, serotonin transporter was observed between pre-optic area and tuberal region of the hypothalamus, in densities and distribution similar to serotonin. The 5-HT1A and 5-HT1B receptors were found with minor differences among itselves regarding the disposition and intensity of staining.

Muitas linhas de pesquisa sugerem que a serotonina tem importantes papéis nos tecidos periféricos durante as afecções articulares. Nosso objetivo neste estudo foi o de investigar a participação da serotonina na incapacitação articular, edema e extravasamento plasmático após a injeção de formalina 2% no joelho de ratos. Incapacitação articular foi medida através do tempo de elevação da pata (TEP; s) durante o período de 1 minuto de caminhada forçada, a cada 5 minutos, durante uma sessão experimental de 60 minutos. Edema articular foi avaliado pelo aumento de diâmetro articular, (DA; mm), e o extravasamento de plasma foi medido pela quantidade de azul de evans (25 mg / kg, i.v., 30 min antes do teste) no líquido sinovial (EP; mg / ml) 1 hora após a injeção de formalina. Formalina evocou duas fases de incapacitação, bem como aumento do DA e EP de forma dose-dependente. Serotonina sozinha (1; 10 e 100 nmol, i.a.) não modificou a nocicepção, entretanto todas as doses aumentaram o DA, e somente a maior dose causou aumento do EP. Serotonina (100 nmol, i.a.) co-injetada com formalina causou hipernocicepção em ambas as fases. Nenhuma dose alterou o DA ou EP. NAN-190 (100, 200 e 600 fmol, i.a.), ciproheptadina (160, 500, 1.500 fmol, i.a.) e ondansetrona (65 e 260 fmol, i.a.) diminuíram a nocicepção na 2ª fase. Nenhuma dose alterou o DA. Ciproheptadina (1.500 fmol, i.a.) aumentou o EP. Sumatriptano (1.5 e 5 pmol, i.a.) causou hipernocicepção na 2ª fase sem alterar o DA ou EP. Cromoglicato (1.6 mg, i.a.) não inibiu a hipernocicepção do sumatriptano nem alterou o DA e EP, assim como os pré-tratamentos com indometacina (2.5 mg/kg, i.p.) e furosemida (20 mg/kg, i.p.). Nossos resultados sugerem que a serotonina causa hipernocicepção ao menos via receptores 5-HT1-3 sem efeitos vasculares associados e que a hipernocicepção periférica do sumatriptano possivelmente é devido a mecanismo celular diferente do atribuído.

La Serotonina (5-HT) es un neurotransmisor detectado tempranamente durante el desarrollo del sistema nervioso central y recientemente se ha descrito su papel sobre los procesos de migración y morfología neuronal. Mediante la inhibición farmacológica de la síntesis de 5-HT durante el desarrollo embrionario, se ha determinado que la reducción en este neurotransmisor produce efectos a largo plazo reflejado en una disminución del peso del cerebro, alteración en la maduración neuronal y una disminución de la complejidad dendrítica. La 5-HT ejerce sus acciones a través de sus receptores ionotrópicos (5HT3) y metabotrópicos (5HT1, 5HT2, 5HT4-5HT7). Algunos de ellos se expresan tempranamente durante el desarrollo embrionario y más aún puede variar su distribución y/o niveles en forma dinámica durante el desarrollo pre y posnatal. Para efectos de esta Tesis se destacan los receptores 5HT1A y 5HT7 los cuales están presentes en estructuras cerebrales como el hipocampo. Interesantemente, el 5HT1A-R se expresa tempranamente durante el desarrollo embrionario; por lo cual se postula que la 5-HT tendría un efecto modulador sobre la migración, diferenciación y viabilidad celular. En cambio, solo se ha descrito una expresión dinámica del 5HT7-R durante el desarrollo posnatal; lo que sugiere una acción de este receptor en estadíos bien definidos. La sobre-expresión de los receptores serotoninérgicos 5HT1A y 5HT7 en líneas celulares, ha permitido estudiar su acoplamiento a distintas cascadas transduccionales. Se ha descrito el acoplamiento a diversas proteínas G que permiten la activación o inhibición de proteínas efectoras como AC, fosfolipasas, regulación de canales iónicos y activación de las vías MAPK y PI3K-Akt, entre otras. Estas vías participan promoviendo la formación de neuritas y dendritas y han sido involucradas con la regulación de la plasticidad sináptica. En contraste, los efectores de estos receptores descritos en líneas celulares no han sido bien definidos en neuronas. Si bien existen algunos antecedentes que apoyan la idea de que la 5-HT regula la morfología neuronal, no se ha establecido la participación de un subtipo de receptor en particular. La activación del 5HT1A-R induce un aumento en el número y largo de neuritas en neuroblastoma de ratón. En relación a estos cambios morfológicos, se ha descrito que la vía de las Rho GTPasas regula el citoesqueleto a través de la modulación de la cofilina, importante regulador del citoesqueleto de actina. Se ha demostrado un acoplamiento entre el 5HT7-R y Gα12 y el aumento del crecimiento de neuritas en neuronas hipocampales, aunque no se ha dilucidado cuáles son sus efectores río abajo. De acuerdo a estos antecedentes se postuló la siguiente hipótesis: “Agonistas de los receptores 5HT1A y 5HT7 activan vías transduccionales que modulan el citoesqueleto, efectos que se asocian a cambios morfológicos de neuronas hipocampales en cultivos”. Los objetivos fueron: 1) Determinar en neuronas hipocampales con distinta madurez, el efecto de agonistas de los receptores serotoninérgicos 5HT1A y 5HT7 sobre proteínas que participan en vías transduccionales, que tienen como blanco el citoesqueleto de microtúbulos y de actina, como Akt-GSK-3β, ERK y cofilina, respectivamente. 2) Determinar el efecto de agonistas de los receptores serotoninérgicos 5HT1A y 5HT7 sobre la morfología de neuronas hipocampales con distinta madurez. Estos objetivos se desarrollaron utilizando antagonistas específicos para los receptores 5HT1A (WAY-100635) y 5HT7 (SB269970). En esta tesis se demostró que la distribución del receptor 5HT1A experimenta una polarización a mayor madurez del cultivo, encontrándose tempranamente en el soma y más tardíamente con una localización somato-dendrítica, sin variar el nivel del receptor. En contraste, la distribución somato-dendrítica del 5HT7-R fue independiente de la madurez del cultivo. A su vez, se detectaron las isoformas 5HT7a-R y 5HT7b-R y cuya relación no varió durante los días del cultivo in vitro (DIV). No obstante, ambas isoformas aumentan significativamente entre los 2 y 14 DIV. El 8OH-DPAT, agonista de los receptores 5HT1A (Ki 10 nM) y 5HT7 (Ki 52 nM), promueve la activación de la vía Akt-GSK-3β a los 2 DIV, efecto que involucraría la participación del 5HT7-R y, probablemente al 5HT1A-R. Adicionalmente, el 8OH-DPAT en neuronas más maduras (7 DIV), aumentó la activación de la Akt, efecto independiente de los receptores 5HT1A y 5HT7. Estos resultados sugieren que este agonista puede activar a otros receptores, lo que plantea una reevaluación de su acción como agonista selectivo del 5HT1A. Por otra parte, a pesar de la activación de la Akt, no se observaron cambios en la fosforilación de la GSK-3β, sugiriendo una disociación de ambas quinasas a este estadío. Adicionalmente, el 8OH-DPAT ó la 5-HT no modificaron significativamente el estado de fosforilación de las ERK1/2. La estimulación durante 24 horas con 8OH-DPAT en neuronas con 2 DIV aumentó significativamente el número de las neuritas primarias, acompañado de un aumento en el largo neurítico total; efectos no asociados a los receptores 5HT1A y 5HT7. Estos resultados sugieren que el 8OH-DPAT activa un receptor que incrementa el número de neuritas sin afectar su largo. Interesantemente, se observó que la estimulación con 8OH-DPAT disminuyó significativamente la fosforilación inactivante de la cofilina en Ser3; efecto insensible a la acción de los antagonistas de los receptores 5HT1A y 5HT7. Similarmente, a los 7 DIV se observó una disminución significativa de los niveles fosforilados de cofilina luego de la estimulación con 5-HT, efecto no asociado a los receptores 5HT1A y 5HT7, sugiriendo la participación de un receptor serotoninérgico desconocido sobre la dinámica de actina. Adicionalmente, la activación del 5HT7-R con 8OH-DPAT y 5HT a los 2 DIV durante 24 h disminuye el número de las dendritas primarias pero promueve el crecimiento. A este mismo estadío neuronal, la 5-HT a través de 5HT1A-R y 5HT7-R aumentó el crecimiento de dendritas secundarias. Por otro lado, se demostró a los 8 DIV que la 5-HT aumenta el número de dendritas primarias más cortas a través de un receptor serotoninérgico desconocido. Adicionalmente, los cambios inducidos por la 5-HT a los 8 DIV, indican que el 5HT1A-R promueve una reducción en el largo de las dendritas primarias, fenómeno observado por la reducción en el número de las dendritas primarias más largas (> 40 μm); efecto también observado en las secundarias más largas (> 20 μm). En apoyo, el análisis de Sholl muestra una disminución de la complejidad neuronal asociada a este receptor. Es decir, el 5HT1A-R inhibe el crecimiento y la complejidad dendrítica, probablemente al frenar el crecimiento o elongación de éstas, quedando por establecer los mecanismos moleculares asociados. En apoyo a este hallazgo, se ha descrito recientemente en hipocampo de ratón adulto que el 5HT1A-R produce una disminución de las dendritas terciarias. En contraste, a los 8 DIV el 5HT7-R promueve un aumento del crecimiento de dendritas primarias y secundarias, siendo este último efecto también observado por la estimulación del 5HT1A-R. En resumen, el 5HT1A-R promueve una disminución de la complejidad dendrítica, en contraste al efecto positivo de la activación del 5HT7-R observado a nivel de las neuritas y dendritas; sugiriendo que estos receptores pueden modular la morfología neuronal de forma diferencial dependiendo de la madurez del cultivo. Además, por primera vez se involucra la participación de los receptores 5HT1A y 5HT7 sobre la morfología neuronal en cultivo primario de hipocampo de rata. Además, este estudio muestra los efectos de agonistas serotoninérgicos sobre vías transduccionales relacionadas a la modulación del citoesqueleto y cambios en la morfología que depende de la madurez de neuronas hipocampales.
Serotonin (5-HT) is a neurotransmitter found early during development of the central nervous system and recently it has been involved in cell migration and neuronal morphology. The pharmacological inhibition of 5-HT synthesis during embryonic development suggests that its reduction produces long-term effects reflected as decreased brain weight, altered neuronal maturation and reduction of dendritic complexity. The 5-HT exerts its actions through ionotropic (5HT3) and metabotropic (5HT1, 5HT2, 5HT4-5HT7) receptors. Some of these receptors are expressed early during embryonic development and their distribution or levels can change dynamically during pre-and postnatal development. This thesis focuses on 5HT1A and 5HT7 receptors, which are present in brain structures such as the hippocampus. Interestingly, the 5HT1A-R is expressed early during embryonic development, suggesting that 5-HT could have a modulating effect on cell migration, differentiation and viability. In contrast, a dynamics expression of 5HT7-R has been described during postnatal development, suggesting a role in well-defined neuronal stages. Overexpression of 5HT1A and 5HT7 serotonin receptors in cell lines has allowed studying their coupling to several transduction pathways. These receptors are coupled to several G protein allowing the activation or inhibition of effector proteins such as AC, phospholipases, regulation of ion channels and activation of MAPK and PI3K-Akt, among others. These pathways promote neurites and dendrites formation, and have been implicated in the regulation of synaptic plasticity. In contrast, the effectors of these receptors described in cell lines have not been well defined in neurons. Although some evidences support the idea that 5-HT regulates neuronal morphology, it has not been established which serotonergic receptors are involved. The 5HT1A-R activation induces an increase in both the number and length of neurites in mouse neuroblastoma. In relation to these morphological changes, it has been described that Rho GTPases pathway regulates the cytoskeleton through the modulation of cofilin, an important regulator of actin dynamics. Additionally, a link between 5HT7-R, activation of Gα12 and the increase of neurite outgrowth in hippocampal neurons has been described, but it has not been elucidated the transduction pathway involved. According to these evidences, the following hypothesis was proposed: “Agonists of 5HT1A and 5HT7 receptors activate pathways that modulate the cytoskeleton, effects that are associated with morphological changes in cultured hippocampal neurons." The aims were to: 1) Determine, the effect of 5HT1A-R and 5HT7-R agonist on proteins involved in transduction pathways, targeting microtubule and actin cytoskeleton like Akt-GSK- 3β, ERK and cofilin, respectively, on hippocampal neurons with different maturity. 2) Determine the effect of 5HT1A-R and 5HT7-R agonist on morphology of hippocampal neurons with different maturity. These objectives were developed using specific antagonists of 5HT1A (WAY-100635) and 5HT7 (SB269970) receptors. In this thesis it was shown that the distribution of 5HT1A receptor undergoes a polarization during the maturity of neurons, being early found in the soma and late with a somato-dendritic distribution but without changes on receptor levels. In contrast, the somato-dendritic distribution of 5HT7-R was independent of neuronal maturity. Besides, the isoforms “a” and “b” of 5HT7-R were detected without changes in their ratio during days in vitro (DIV). Nonetheless, both isoforms increased significantly from 2 to 14 DIV. The 8OH-DPAT, a 5HT1A (Ki 10 nM) and 5HT7 (Ki 52 nM) receptor agonist, promotes the activation of the Akt-GSK-3β pathway at 2 DIV, effect which involves the participation of 5HT7-R and probably the 5HT1A-R. Additionally, in more mature neurons (7 DIV) stimulation with 8OH-DPAT increased activation of Akt, an effect independent of 5HT1A and 5HT7 receptors. These results suggest that this agonist may activate other receptors, and hence demands a reconsideration of its action as selective 5HT1A agonist. Moreover, in spite of Akt activation, no changes were observed in the phosphorylation levels of GSK-3β, suggesting dissociation of both kinases at this stage. Additionally, neither 8OH-DPAT nor 5-HT altered the phosphorylation levels of ERK1/2. Stimulation for 24 hours with 8OH-DPAT at 2 DIV significantly increased the number of primary neurites, accompanied by an increase in the overall length of neurites; effects which are not related to 5HT1A and 5HT7 receptors. These evidences suggest that 8OH-DPAT targets an unknown receptor whose activation increases the number of neurites without affecting their length. Interestingly, it was observed that stimulation with 8OH-DPAT significantly decreased the inactivating phosphorylation of cofilin in Ser3; an effect insensitive to the antagonists of the 5HT1A and 5HT7 receptors. Similarly, a significant decrease of phosphorylated cofilin levels after stimulation with 5-HT was observed at 7 DIV; effect not associated to 5HT1A and 5HT7 receptors, suggesting the participation of an unknown serotonin receptor modulating actin dynamics. Additionally, the 5HT7-R activation with 8OH-DPAT and 5-HT at 2 DIV during 24 h decreases the number of primary dendrites but promotes its growth. At this neuronal stage, 5-HT stimulates secondary dendrite growth through both 5HT1A-R and 5HT7-R. Furthermore, this thesis demonstrated at 8 DIV that 5-HT increases the number of short primary dendrites via an unknown serotonergic receptor. Additionally, the changes induced by 5-HT at 8 DIV, indicate that 5HT1A-R promotes a reduction in the length of the primary dendrites, a phenomenon observed as reduction in the number of longer primary dendrites (> 40 um); effect also observed in longer secondary dendrites (> 20 um). In accordance, Sholl analysis shows a decrease in neuronal complexity associated with this receptor. Thus, 5HT1A-R inhibits primary dendritic growth and complexity, probably by slowing the growth or elongation, and the molecular mechanisms associated remains to be explained. In support of this finding, it has been recently described in adult mouse hippocampus, that 5HT1A-R promotes a decrease of tertiary dendrites. In contrast, this Thesis described that 5HT7-R induces an increased growth of primary and secondary dendrites at 8 DIV; being the latter effect also observed by 5HT1A-R stimulation. To summarize, the 5HT1A promotes a reduction of dendritic complexity in contrast to the positive effect of 5HT7 receptors observed in both neurites and dendrites; suggesting that these receptors differentially modulate the neuronal morphology depending on neuron maturity. Furthermore, we described for first time the participation of 5HT1A and 5HT7 on neuronal morphology in primary culture of rat hippocampal neurons. Additionally this study shows the effects of serotonergic agonists on transduction pathways related to cytoskeleton modulation and morphological changes depending on maturity of hippocampal neurons.

Serotonin (5-HT) is a neurotransmitter involved in nervous system development, being an important modulator of respiratory rhythm via activation of diverse receptors on respiratory neurons. Selective serotonin reuptake inhibitors (SSRIs) such as fluoxetine act as antidepressants and are generally prescribed in depression therapy, including to pregnant women. This study investigated the effects of prenatal (E15-21) exposure to fluoxetine on the ventilatory and metabolic responses to 7% CO2 (hypercapnia) and 10% O2 (hypoxia) of male and female rats during postnatal development (P0-82). To this end, osmotic pumps were implanted subcutaneously in pregnant female rats at embryonic day (E) 15 and delivered vehicle (VEH) or fluoxetine (SSRI, 10 mg/Kg/day) during 7 days. Respiratory frequency (fR), tidal volume (Vt), ventilation (Ve ), O2 consumption (''VO2 ) and air convection requirements (Ve/VO2 ratio) of pups from these litters were studied. In P0-2 male rats, the SSRI group showed a lower Vt and a higher fR in room air conditions, whereas female rats of SSRI group showed a lower Vt in normocapnia normoxica and a higher hyperventilation induced by hypercapnia. At P6-8, male SSRI animals presented a higher fR during hypoxia together with a decrease in the number of neurons that express 5-HT in the caudal dorsal raphe (RDC). P6-8 females from ISRS group showed an attenuated fR during hypoxia. No differences were observed between male rats in the VEH and ISRS groups at P12-14 although there was an increase in the number of 5-HT neurons in the RD. SSRI females showed an attenuated hypercapnic ventilatory response. At P24-26, male SSRI animals showed a lower VEin room air conditions, a higher ventilatory response to hypercapnia and to hypoxia, together with an increase in the number of 5-HT neurons in the ROB and a higher density of TH expression in the LC area. P24-26 SSRI females displayed a lower Ve/V O2 due to a higher V O2 in room air conditions and a higher hyperventilation induced by hypercapnia. In P76-82 male rats, the SSRI group hypoventilated in room air conditions during both wakefulness and NREM sleep and showed a higher increase in Vt induced by hypoxia during wakefulness. These animals showed a higher number of 5-HT neurons in the ROB, RPA and an increase in the number of neurons that express TH in the A5 and in the LC rostral area. Finally, at P76-82, female SSRI rats showed a higher fR in room air conditions during both wakefulness and NREM sleep, an attenuated hypercapnic ventilatory response due to an attenuation of fR during NREM sleep; and an attenuated hypoxic ventilatory response during wakefulness. Also, these animals showed a decrease in the number of 5-HT neurons in the RD. Taken together, these data indicate that SSRI exposure during the prenatal period alters the development of the brainstem respiratory network and results in long lasting and sex specific changes in breathing pattern and in the ventilatory responses to respiratory challenges demonstrating that central and/or peripheric chemoreception may be disrupted in these animals.
A serotonina (5-HT) é um neurotransmissor envolvido no desenvolvimento de vários sistemas neuronais, sendo um importante modulador da ritmogênese respiratória via ativação em diversos receptores nos neurônios respiratórios. Os inibidores seletivos de recaptação de serotonina (ISRSs), como a fluoxetina, agem como antidepressivos e geralmente são prescritos na terapia da depressão, incluindo às mulheres grávidas. Este estudo investigou os efeitos de uma exposição prenatal [dia embrionário (E) 15-21] à fluoxetina nas respostas ventilatórias e metabólicas à hipercapnia (7% CO2) e hipóxia (10% O2) em ratos e ratas durante o desenvolvimento pós-natal (P0-82). Para isso, bombas osmóticas foram implantadas subcutaneamente em ratas grávidas em E15 e forneceram veículo (CTRL) ou fluoxetina (ISRS, 10 mg/Kg/dia) durante 7 dias. A frequência respiratória (fR), o volume corrente (Vt), a ventilação (V e ), o consumo de O2 (V O2) e o equivalente respiratório (V E/VO2) dessas ninhadas foram analisados. Em ratos P0-2, o grupo ISRS apresentou um Vt menor e uma fR maior em ar ambiente. Já as fêmeas do grupo ISRS apresentaram um Vt menor em normocapnia normóxica e um aumento da hiperventilação induzida por hipercapnia. Na idade P6-8, machos ISRS apresentaram uma fR maior durante a hipóxia juntamente com uma queda de 37,9% no número de neurônios que expressam 5-HT na rafe dorsal caudal (RDC), as fêmeas ISRS por sua vez, apresentaram uma fR atenuada em hipóxia em 6%. Nenhuma diferença das varíaveis respiratórias entre grupos foi observada em machos da idade P12-14, porém houve um aumento de 84,7% no número de neurônios que expressam 5-HT na rafe dorsal (RD). As ratas ISRS P12-14 apresentaram uma resposta ventilatória atenuada à hipercapnia. Na idade P24-26, os ratos ISRS demonstraram uma Ve menor em ar ambiente, uma maior resposta ventilatória à hipercapnia e à hipóxia, juntamente com um aumento de 56% no número de neurônios que expressam 5-HT na rafe obscurus (ROB) e uma maior densidade na expressão de tirosina hidroxilase (TH) na região do Locus coeruleus (LC) (16% de aumento). As fêmeas ISRS exibiram um menor V e/V O2 devido a um maior V O2 em normocapnia normóxica e uma maior hiperventilaçao induzida por hipercapnia. Nos ratos P76-82, o grupo ISRS hipoventilou em condições de ar ambiente durante vigília e sono NREM e apresentou um maior aumento no Vt induzido por hipóxia durante a vigília. Estes animais apresentaram um maior número de neurônios que expressam 5-HT na ROB, RPA e um aumento do número de neurônios que expressam TH na região A5 e na região rostral do LC. Finalmente, as fêmeas ISRS da idade P76-82 apresentaram uma maior fR em condições de ar ambiente durante a vigília e o sono NREM, uma resposta ventilatória a hipercapnia atenuada em devido a atenuação da fR durante o sono NREM; e uma resposta ventilatória a hipóxia atenuada durante a vigília. Adicionalmente, estes animais apresentaram uma redução do número de neurônios que expressam 5-HT na RD. Estes resultados, em conjunto, sugerem que uma exposição a ISRS durante o período prenatal altera o desenvolvimento da rede respiratória do tronco encefálico e promove efeitos em longo prazo e sexo específicos na respiração basal como em condições de desafios respiratórios, demonstrando que a quimiorrecepção central e/ou periférica pode estar alterada nestes animais.

Full textSerotonin (5-HT) is a neurohormone with complex effects in humans and animals. Although serotonergic signaling has been suggested to promote the development of colon tumors, the reduction in 5-HT levels was reported to increase the risk of colon cancer. Here, we sought to investigate how 5-HT synthesis modulates colon carcinogenesis. This hypothesis was explored in mechanistic experiments that carcinogenically exposed or not mice to azoxymethane. It revealed that carcinogenic exposure increased the synthesis of 5-HT in the colon since 5-HT release and decay were inhibited, while its synthesis and reuptake are promoted. After 24 weeks from the first carcinogenic exposure, the deletion of 5-HT synthesis increased tumor multiplicity, while following 12 weeks it promoted the development of preneoplastic lesions, and cell proliferation in the colon. Interestingly, 72 hrs after the sixth and last carcinogenic exposures the number of aberrant crypts were detected reduced in the absence of 5-HT, which occurred together with a reduced proliferation, but increased apoptosis and DNA damage. Finally, 5-HT modulated genomic repair mechanisms. We conclude that serotonergic synthesis seems to be a protective factor of the intestinal colon, which inhibited case facilitates tumor development in this tissue.

Full textRomantic love involves biochemical processes in which substances such as neurotransmitters, neuromodulators and hormones interact with other nerve cells or organs. When being in love, dopamine levels increases, generating attention, desire and motivation in everything related to the beloved person. Serotonin, however, is present in low levels in this state. When the body does not supply the necessary amount of dopamine, oxytocin is released. Oxytocin is vital in long term relationships. Understanding the mechanism of oxytocin in humans is crucial not only for academic knowledge of the chemistry of love but also because it provides new lights for the treatment of some psychological disorders.

A serotonina atua na regulação de eventos biológicos envolvidos no desenvolvimento precoce do sistema nervoso. Neste período crítico o aumento dos níveis encefálicos deste neurotransmissor pode alterar componentes do sistema serotoninérgico, como o transportador de serotonina. Os inibidores seletivos da recaptação de serotonina bloqueiam o transportador e aumentam a quantidade de serotonina extracelular. O aumento farmacologicamente induzido neste período é capaz de gerar alterações funcionais e estruturais permanentes ao sistema nervoso. Este estudo teve como objetivo avaliar a expressão gênica do SERT e o conteúdo de 5-HT no hipotálamo de ratos manipulados com fluoxetina durante a lactação. Ratos Wistar foram divididos em dois grupos, de acordo com a manipulação farmacológica realizada do 1º ao 21º dia de vida, Salina (n=9) e Fluoxetina (n=10), compostos por filhotes que receberam, respectivamente, solução de salina (NaCl 0.9%, 10μl/g, s.c.) e fluoxetina (10mg/kg, 10μl/g, s.c.). Foram analisados: a expressão gênica do SERT realizada no hipotálamo aos 21 e 40 dias e o peso corporal foi mensurado nos dias 1, 7, 14, 21 e 40. O presente trabalho demonstrou que a manipulação neonatal com fluoxetina promoveu menor ganho de peso corporal a partir do 14º dia até o final do experimento e aumento na expressão gênica do SERT aos 40 dias. Estes resultados indicam que a manipulação neonatal crônica do sistema serotoninérgico desencadeia alterações no principal componente de controle da neurotransmissão serotoninérgica, o SERT e consequentemente no neurotransmissor serotonina.

Full textSerotonin or 5-hydroxytryptamine (5-HT) is a substance found in many tissues of the body, including as a neurotransmitter in the nervous system, in which may exert varied post-synaptic actions. Inside the neuro-axis, the location of 5-HT neurons is almost restricted to the raphe nuclei of the brainstem, such that 5-HT-immunoreactivity can be considered a marker of the raphe nuclei. The raphe nuclei are located in the brainstem, at or near the midline. The serotonergic groups were originally alphanumerically classified as B1 to B9 towards caudorrostral in rats and can be divided into upper and lower groups. In this study the distribution of serotonergic neurons was studied using immunohistochemistry in the brain of the rock cavy (Kerodon rupestris), a species of rodent endemic to Northeastern Brazil. The cytoarchitectonic location of serotonergic neurons was established in series of adjacent coronal and sagittal sections stained by the Nissl method and immunohistochemistry for 5-HT. Thus, we defined the raphe rostral linear, caudal linear, dorsal, median, and paramedian pontine raphe nuclei, and B9 cluster, constituting the rostral group, and the interpositus, magnus, obscure and palidus, constituting the caudal part of the group, comparable to which has been described for other mammalian species
A serotonina ou 5-hidroxitriptamina (5-HT) ? uma subst?ncia encontrada em muitos tecidos do organismo, inclusive no sistema nervoso como neurotransmissor, onde pode exercer a??es p?s-sin?pticas variadas. Dentro do neuro-eixo, a localiza??o dos neur?nios 5-HT ? quase absoluta nos n?cleos da rafe do tronco encef?lico, de tal maneira que 5-HT neuronal pode ser considerada um marcador dos n?cleos da rafe. Os n?cleos da rafe est?o localizados no tronco encef?lico, na linha m?dia ou suas proximidades. Os grupamentos serotonin?rgicos foram originalmente classificados alfanumericamente como B1 a B9 no sentido caudorrostral no rato e podem ser divididos em grupos superior e inferior. Neste trabalho a distribui??o dos neur?nios serotonin?rgicos foi estudada com imunoistoqu?mica no c?rebro do moc? (Kerodon rupestris), uma esp?cie de roedor end?mica da regi?o Nordeste do Brasil. A localiza??o citoarquitet?nica dos neur?nios serotonin?rgicos foi estabelecida em s?ries de sec??es coronais e sagitais adjacentes submetidas a colora??o pelo m?todo de Nissl e imunoistoqu?mica para 5-HT. Assim, foram delimitados os n?cleos da rafe linear rostral, linear caudal, dorsal, mediano, paramediano e pontino da rafe e grupamento B9, compondo o grupo rostral, e os n?cleos interp?sito, magno, obscuro e p?lido, compondo o grupo caudal, compar?vel ao que j? foi descrito para outras esp?cies de mam?feros

Resumo: Variações na PCO2/pH sanguíneo em vertebrados são detectadas, principalmente, pelos quimiorreceptores centrais. Em aves, os tipos de neurônios quimiossensíveis intermediadores da resposta ventilatória não são conhecidos, assim como sua localização. Por outro lado, em mamíferos, sabe-se que estes quimiorreceptores compreendem uma grande população neuronal e estão distribuídos no sistema nervoso central. Dentre os tipos de quimiorreceptores centrais, em mamíferos, destacam-se os neurônios serotoninérgicos (5-HT) contidos em elevada concentração na rafe e que possuem projeções às principais regiões envolvidas na regulação da respiração. A partir do exposto, objetivou-se verificar a participação da serotonina no controle respiratório de frangos. Foram utilizados pintos carijós machos e fêmeas, em dois conjuntos experimentos com abordagem distintas que propuseram reduzir o conteúdo de serotonina liberado no espaço sináptico em resposta à hipercapnia e à hipóxia. O primeiro com deleção química dos neurônios 5-HT, mediante a injeção de 1µL de anti-SERT-SAP (0,1µM) no quarto ventrículo (4V), os grupos controle receberam injeções de PBS e IgG-SAP. O segundo experimento por inibição da biossíntese de serotonina pela p-clorofenilalanina (PCPA) em 100mg/kg i.p. (animais controles receberam salina 0,9% ou solução veículo). O anti-SERT-SAP reduziu o número de neurônios 5-HT no rombencéfalo dos pintos (P<0,05). Os animais anti-SERT-SAP apresentaram menor frequência respiratória (FR) que os ...

Abstract: Variations in PCO2/pH blood in vertebrates are mainly detected by central chemoreceptors. In birds, the types of chemosensitive neurons mediating the ventilatory response are not known, as is their location. On the other hand, in mammals, it is known that these chemoreceptors comprise a large neuronal population and are distributed in the central nervous system. Among the types of central chemoreceptors in mammals, serotoninergic (5-HT) neurons are found in high concentration in the raphe and have projections to the main regions involved in the regulation of respiration. From the above, we aimed to verify the participation of serotonin in respiratory control of broilers. Male and female carybush chicks were used in two sets with distinct approaches that proposed to reduce the serotonin content released in the synaptic space in response to hypercapnia and hypoxia. The first with chemical deletion of 5-HT neurons, by injecting 1μL of anti-SERT-SAP (0.1μM) into the fourth ventricle (4V), the control groups received injections of PBS and IgG-SAP. The second experiment by inhibition of serotonin biosynthesis by p-chlorophenylalanine (PCPA) at 100mg/ kg i.p. (control animals received 0.9% saline or vehicle solution). Anti-SERT-SAP reduced the number of 5-HT neurons in the hindbrain of chicks (P <0.05). Anti-SERT-SAP animals presented lower respiratory rate (RF) than controls in ambient air (P<0.05). When they were exposed to hypercapnia of 7%, the ventilation (VE) of these animals ... (Complete abstract click electronic access below)
