Full textGlioblastoma multiforme (GBM) is a serious disease and no effective treatment is availabe, especially because the drugs cause significant adverse reactions in therapeutic doses. Methotrexate (MTX) is a cytotoxic drug used to treat many neoplasms, however, their use is limited by the low bioavailability and adverse reactions. Nanotechnology has been used to increase the effectiveness of antitumor drugs in order to direct them to the site of action and to reduce adverse effects. Accordingly, we carried out an experimental approach with MTX lipid nanocapsules (MTX LNC) to evaluate the uptake mechanisms in glioblastoma and microglia cell lines, and the therapeutic efficacy of MTX LNC in vitro and in vivo systems. Initially, fluorescence microscopy assays employing specific pharmacological blockers for membrane transport showed that the MTX LNC stained with Rhodamine B penetrated into GL261 tumor cells by caveolae-mediated endocytosis, and in BV2 microglia cells by phagocytosis and macropinocytosis. Treatment with MTX solution or MTX LNC (at corresponding concentrations) on GL261 cells inhibited the proliferation; increased DNA fragmentation, but only the LNC induced cell death by necrosis and decreased the number of cells in the G1/G0 phase of the cell cycle. In BV2 cells, treatment with MTX solution or MTX LNC inhibited proliferation, reduced number of cells in the G1/G0 phase of the cell cycle, increased DNA fragmentation and cell death, induced by apoptosis and late apoptosis. Intravital microscopy study showed that the MTX LNC across the Blood-Brain Barrier (BBB) of C57BL/6 female mice after intravenous or oral administrations, without damaging its structure. The area of glioblastoma in vivo was reduced in animals oral treated with MTX LNC comparing to saline treated mice. This reduction was not observed in animals treated with MTX solution. Together, the data herein obtained show that MTX LNC penetrate the cell membrane and cause cell toxicity on glioma and neurons lineage, cross the BBB and suggest that the nanoencapsulation of MTX can be an important strategy for the treatment of glioblastoma.

Full textOne of the major needs of living cells is the regulation of their internal environment. Apart from being of considerable theoretical importance, the transport of water is of practical importance in a broad range of process, from the protection of cells undergoing cryogenic preservation to the effects of certain hormones in some tissues. Virtually all the cells are submitted the osmotic transitions during their period of life, because both intracellular metabolism and transmembrane transport produce fluctuations in concentrations of osmolytes. The regulation of cellular volume is a phenomenon ubiquitous and allows, to the cells, to keep their normal volume. Cells subjected to acute anisosmotic shocks suffer from fast alterations in volume (depending on the osmotic gradient and on the permeability of the membrane to the water and osmotically active substances), and followed or not by a slow volume regulation response. Thus, the present work aims to clarify some aspects of the water transport in murine melanoma S91 cells subjected to anisosmotic conditions. S91 murine melanoma cells were grown in F12 HAM medium (290 mOsm.kgH2O-1). Morphometric measurements of relative changes in cell volume were performed using a video microscopy system and a PC software (Image Pro-Lite, Media Cybernetics). The experimental cells were exposed either to acute hyposmotic shocks (190 mOsm.kgH2O-1) or to acute hyperosmotic shocks (350 mOsm.kgH2O-1), in different temperatures (ranging from 17 to 37 oC) and in the presence of HgCl2 (from 0,001 to 1000 µM), an aquaporin blocker. The results of the present study indicate that: (i) the time of volume regulation in S91 murine melanoma cells is dependent on temperature; (ii) the values of osmotic water flow are compatible with activation energy through aquaporins (E < 6 kcal.mol-1) and (iii) HgCl2 treatments affect osmotic behavior of S91 murine melanoma cells in a dose-response manner and also suggest the presence of more than one type of aquaporin. Minimum osmotic water permeabilities were observed in a range of µM HgCl2 treatments.

A ausência de um modelo animal adequado de infecção crônica para estudo da cromoblastomicose experimental e o desconhecimento sobre as formas fúngicas infectantes de Fonsecaea pedrosoi estimularam a realização da presente investigação. Inicialmente, diferentes formas micelianas de F. pedrosoi, hifas, conídios e células conidiogênicas, foram testadas quanto ao seu potencial infectivo em camundongos BALB/c. Cada estrutura demonstrou capacidade distinta de sobrevida frente à resposta tecidual do hospedeiro. A transformação in vivo do inóculo fúngico para corpos escleróticos somente foi verificada nas infecções com células conidiogênicas. Neutrófilos parecem ser importantes no controle de F. pedrosoi, possivelmente pela degranulação e liberação de produtos tóxicos, enquanto macrófagos podem ser mais relevantes nos processos de clearance. A inoculação do fungo em único sítio produziu resposta inflamatória com formação de abscesso rico em fagócitos, ocorrendo eliminação da infecção em até dois meses. No entanto, coestímulo antigênico em dois sítios distintos, tais como pata s.c. e peritônio, respectivamente, com células fúngicas viáveis e inviáveis, nas diferentes linhagens de camundongos e animais knockouts, provocou a formação de lesões multifocais ricas em histiócitos e infecção persistente por F. pedrosoi, ocorrendo cura clínica e micológica desses animais, em geral, após 4 meses. Nos animais coestimulados, quando o foco primário (abscesso rico em neutrófilos) desaparecia, a migração de neutrófilos se intensificava para o sítio secundário (lesões focais ativas), culminando com a eliminação fúngica. Tais dados corroboraram para hipótese de atuação individualizada da resposta imune em focos múltiplos, porém com resolução, sistemicamente, coordenada das lesões. Após imunização das mucosas e infecção da pata com células de F. pedrosoi também foi verificada maior duração das lesões infecciosas, indicando que a apresentação antigênica de sítios distintos poderia estar envolvida com mecanismos tolerogênicos aos antígenos fúngicos. Camundongos CD4 KO que receberam duplo-estímulo, embora manifestassem agravamento das lesões nos períodos iniciais pós-inoculação fúngica, controlaram a infecção mais tardiamente. Progressão exarcebada e agravamento da infecção foram verificados em animais KO CD8 coestimulados. Camundongos co-estimulados apresentaram lesões com perfil anatomopatológico similar, no entanto, os animais IL-10 KO não desenvolveram infecção prolongada após coestimulação. Animais XID coestimulados desenvolveram infecção crônica, o que demonstrava a possibilidade das células B1 atuarem antagonicamente à resposta imunossupressora. Em outro estudo, selecionamos uma cepa bacteriana com propriedades antagônicas aos fungos filamentosos, identificada como B. subtilis, para ser utilizada em ensaios de interação com a cepa de F. pedrosoi. Em cocultivos, verificamos alterações celulares, como modificação das hifas para formas artroconidiadas, produção de clamidoconídios terminais e indução da síntese de melanina fúngica. Tais células cocultivadas foram inoculadas em camundongos, sendo os clamidoconídios terminais mais resistentes in vivo a ação dos fagócitos. No último experimento, utilizamos culturas axênicas de F. pedrosoi, mantidos em cultivos por seis meses. Formas fúngicas variadas, tais como células arredondadas, clamidoconídios terminais e intercalares, com parede celular composta por múltiplas camadas, foram analisadas por microscopia óptica e eletrônica. Essas células fúngicas foram inoculadas em camundongos BALB/c, produzindo infecção crônica, principalmente em grupo de animais infectados em dois sítios. Por fim, nossos achados evidenciaram que o desenvolvimento de um modelo murino adequado para cromoblastomicose depende de fatores ligados ao parasito e hospedeiro. Células fúngicas ou formas, potencialmente, infectantes devem ser utilizadas de modo preferencial no desenvolvimento dos modelos experimentais, devendo os mecanismos de imunossupressão, como a coestimulação antigênica, ser empregados como “ferramenta auxiliar” para ampliar as chances de sucesso na obtenção de lesões crônicas em animais hígidos.
This study was prompted by the lack of a satisfactory chronic infection animal model for studies of experimental chromoblastomycosis and the fact that very little is known about the infective fungal forms of Fonsecaea pedrosoi. First, we investigated the infective potential of different mycelial forms of F. pedrosoi, hyphae, conidia and conidiogenous cells, in BALB/c mice. The extent to which each structure could survive the host tissue response was found to vary. In vivo transformation of the fungal inoculum into muriform cells was only observed when the mice were infected with conidiogenous cells. Neutrophils appeared to play an important role in the control of F. pedrosoi, possibly by degranulating and releasing toxic products, while macrophages may be of greater importance in clearance. Fungal inoculation of a single site led to an inflammatory response accompanied by the formation of abscesses rich in phagocytes. The fungus was eliminated efficiently in up to two months. However, antigenic co-stimulation with viable and nonviable fungal cells in two different sites, such as the footpad (s.c.) and peritoneum, led to the formation of multifocal lesions rich in histiocytes and to prolonged F. pedrosoi infection in different strains of mice and knockout animals. Clinical and mycological cure in these animals generally occurred after 4 months. When the primary focus in the co-stimulated animals (an abscess rich in neutrophils) disappeared, neutrophil migration to the secondary site (active multifocal lesions) increased, culminating in the elimination of the fungi. These data support the hypothesis that multifocal infections show individual immune responses, while systemic resolution of lesions is coordinated as a whole. After the mucosae had been immunized and footpads had been infected with F. pedrosoi cells, infectious lesions were found to be more prolonged, indicating that antigen presentation at different sites may be involved in peripheral tolerance mechanisms. Although lesions in co-stimulated CD4 KO mice worsened during the initial period following inoculation with the fungus, the mice were found to control the infection later. Exacerbated inflammatory progression and a worsening of the infection were observed in co-stimulated CD8 KO animals. Lesions in co-stimulated KO mice had a similar pathologic profile, but IL-10 KO animals did not developed prolonged infection after co-stimulation. Co-stimulated xid mice developed chronic infection, showing that B1 cells may have an antagonistic effect on the immunosuppressive response. In another study, we selected the bacterial strain B. subtilis, which has known antagonistic properties against filamentous fungi, for use in interaction assays with the F. pedrosoi strain. The main cell changes observed after co-culture were the transformation of hyphae into arthroconidial forms and the production of terminal chlamydoconidia. The induction of synthesis of fungal melanin was also observed. Fungal cells from co-cultures were inoculated into mice. The chlamydoconidia from these co-cultures were more resistant in vivo to the actions of phagocytes. In the final experiment, we used axenic F. pedrosoi cultures that had been maintained for six months. Various fungal forms, such as round cells and terminal and intercalary chlamydoconidia, with cell walls made up of multiple layers, were found in aged cultures. When inoculated into BALB/c mice, these fungal forms produced chronic infection, primarily in the group of animals infected at two sites. Our findings show that the development of a satisfactory murine model of chromoblastomycosis depends on factors associated with the parasite and the host. Potentially infective fungal cells should preferably be used when developing experimental models, and immunosuppression mechanisms such as antigenic costimulation should be used as “auxiliary tools” to increase the likelihood of obtaining chronic lesions in healthy animals.

Full textThe occurrence of tuberculosis (TB) reaches much of the world's population and the prevalence is accompanied by the World Health Organization (WHO) since 1990. The same organization publishes the overall situation of the disease, as well as the situation of countries where the disease is not under control. Moreover, in recent years the number of people infected with Mycobacterium tuberculosis grows for many reasons, especially those derived from social inequality, AIDS, migration and the emergence of resistant bacilli to drugs. Moreover, the infection in the central nervous system (CNS) the bacillus is one of the most devastating clinical manifestations of the disease. This is called extrapulmonary neurotuberculosis (Ntb) and stands out with a high rate of mortality and morbidity among the extrapulmonary manifestations. The risk factors include age Ntb, coinfection with HIV, malnutrition, children with recent measles, alcoholism, malignant diseases, the use of immunosuppressant‟s in adults and in community prevalence of the disease. However, pathophysiological mechanisms of the disease need to be better understood. In this respect, more research is urgently needed to better understand the disease and to study new vaccines against the disease. Methods: On day 0 C57BL / 6 mice were challenged in the CNS of the lateral ventricle with micro stereotactic injection technique containing virulent Mycobacterium tuberculosis (H37Rv). After 30 days, the brain and lung CFU were analyzed and histology. Results: In this study, we observed large numbers of bacilli in the CNS determined by the CFU. Moreover, histological analysis showed an intense inflammatory activity in the ventricle while the animal was challenged with H37Rv. Thus demonstrating a model infection with H37Rv strain infused into the lateral ventricle of the CNS in male C57BL / 6 mice. In conclusion, this model is the closest to the normal course of disease in humans, as presented granulomatous tissue lesion characteristics therefore an important strategy for studying the pathophysiology well as mediators involved in the progression, and prevention of this disease.
A ocorrência da tuberculose (TB) atinge grande parte da população mundial e essa prevalência é acompanhada pela Organização Mundial de Saúde (OMS) desde 1990. A mesma organização publica anualmente a situação global da doença, assim como também a situação dos países onde a doença não está sob controle. Além disso, nos últimos anos o número de pessoas infectadas pelo Mycobacterium tuberculosis cresce por muitas razões, principalmente as derivadas de desigualdade social, AIDS, migração e o surgimento de bacilo resistente aos medicamentos. Além disso, a infecção no Sistema Nervoso Central (SNC) pelo bacilo é uma das manifestações clínicas mais devastadoras da doença. Esta forma extrapulmonar é denominada neurotuberculose (Ntb) e se destaca com uma elevada taxa de mortalidade e morbidade entre as manifestações extrapulmonares. Os fatores de risco para a Ntb incluem a idade, a coinfecção com o HIV, desnutrição, crianças com sarampo recente, alcoolismo, doenças malignas, o uso de imunossupressores em adultos e prevalência da doença na comunidade. Entretanto, mecanismos fisiopatológicos da doença precisam ser melhor compreendidos. Neste sentido mais pesquisas são urgentemente necessárias para uma melhor compreensão da doença e para estudar novas vacinas contra a doença. Métodos: No dia 0 camundongos C57BL/6 foram desafiados no ventrículo lateral do SNC com técnica de micro injeção estereotáxica contendo cepa virulenta Mycobacterium tuberculosis (H37Rv). Após 30 dias, o cérebro e pulmão foram analisados por CFU e histologia. Resultados: Neste estudo observou-se grande número de bacilos no SNC determinadas pelo CFU. Além disso, a análise histológica mostrou uma intensa atividade inflamatória no ventrículo, quando o animal foi desafiado com H37Rv. Demonstrando assim um modelo de infecção com a cepa H37Rvinfundida no ventrículo lateral do SNC nos camundongos machos C57BL/6. Em conclusão, este modelo é o mais próximo com o curso normal da doença em humanos, pois apresentou lesão tecidual com características granulomatosa portanto uma importante estratégia para estudar a fisiopatologia assim como mediadores envolvidos na progressão e prevenção desta doença.

Many compounds isolated from lichens exhibit biological activity, and a number of them are proven sources of antitumor drugs. Even simple structural changes to these bioactive compounds can lead to potentiation of their activity. The purposes of this study were to evaluate the antiproliferative activity and selectivity of the following compounds isolated from lichens: atranorin; diffractaic, divaricatic, perlatolic, psoromic, norstitic, protocetraric, and fumarprotocetraric acids; and alkyl derivatives. Cytotoxicity tests based on the sulforhodamine B dye were performed on seven lines of neoplastic cells and one line of normal cells (3T3)

Full textOropouche (OROV) is an arbovirus that occurs in the South American, Amazon region, producing outbreaks of acute febrile illness occasionally associated to meningoencephalitis. Approximately 500,000 cases of Oropouche have been reported in Brazil in the last 60 years. However, there is no available vaccine for OROV. We show here the development of an animal model of OROV suitable for studies on pathogenesis and vaccine testing. A vaccine prototype based on recombinant OROV nucleocapsid protein (NrOROV), an important viral antigen, was evaluated in the animal model. Initialy, we observed that all 12-week-old Balb/c mice inoculated intracerebrally with 8x105 PFU died after the third day of infection. Surprisingly, OROV genome was detectable in the liver as early as 12 hours post infection (pi) and in the spleen at 24 hours pi at 3 log10 PFU/g. Besides, high viral titers were found in brain and spinal cord. To test the NrOROV as a vaccine candidate, animals divided in 5 groups were immunized subcutaneously 3 times, two weeks apart with either OROV, OROV and Freud complete Adjuvant (FCA), NrOROV, NrOROV and FCA, NrOROV and Poly I:C and Montanide ISA 720. The experiment also included a group of naïve animals. After the third immunization, the animals were challenged with 10LD50 by intracerebral route and followed for 20 days. The animals immunized with NrOROV and adjuvants developed specific antibodies that were not able to neutralize the virus or confer protective immunity against OROV. Nevertheless, mice immunized with OROV showed high levels of neutralizing and protective antibodies. Despite the discouraging results with NrOROV as a vaccine, the mouse model is suitable to study pathogenesis, and to test other vaccines for OROV.

Full textThe low responsiveness of melanoma to traditional treatments together with its increasing incidence makes the development of new therapeutic strategies against this type of cancer extremely important. In this study, we used a murine melanoma model to evaluate the effects of synthetic phosphoethanolamine (PEA) on the development of this tumor. In vitro, PEA had an inhibitory effect on the proliferation of B16F10 cells, inducing apoptosis after 24 to 72h stimulation. In vivo, oral treatment of melanoma-bearing animals with different doses of PEA (10, 20 e 40mg/Kg) during 10 or 20 consecutive days resulted in reduced tumor volumes (at least 70% compared to the control) and in expressive macroscopic differences. PEA also induced a dose-dependent increase of apoptosis and decrease in tumor cell proliferation. The treatment also resulted in hematological changes, such as increased numbers of platelets, erythrocytes and leukocytes. Among leukocytes, we observed a higher proportion of lymphocytes and monocytes after 10 and 20 days of treatment, respectively. In addition, PEA induced higher levels of the pro-inflammatory cytokine IL-6 and of the anti-inflammatory cytokines IL-10 and TGF-, and it also induced a lower production of the pro-inflammatory cytokine IFN-. No differences were observed in the levels of IL-1, TNF-, IL-12p70 and IL-17 upon treatment. Our results demonstrate an inhibitory role of PEA in the development of melanoma, contributing to a better understanding of its antitumoral activity.

A Doença Esteatótica Não Alcoólica do Fígado (do inglês Nonalcoholic Fatty Liver Disease – NAFLD) é uma doença crônica hepática de caráter espectral, que vai desde a esteatose simples até a esteato-hepatite não alcoólica. A progressão para cirrose e carcinoma hepatocelular têm sido descrita. A NAFLD apresenta aspectos histológicos semelhantes à doença hepática relacionada ao álcool (esteatose, inflamação lobular, corpúsculos de Mallory e fibrose), mas acomete indivíduos com história negativa de consumo excessivo de álcool. A NAFLD é uma das principais doenças crônicas hepáticas mundiais, e os indivíduos obesos representam a maioria dos casos da doença. Os mecanismos envolvidos na progressão da esteatose para esteato-hepatite não são bem compreendidos. Neste aspecto, modelos murinos da NAFLD têm sido frequentemente utilizados para elucidação destes mecanismos. A maioria dos modelos disponíveis é resultante de modificações genéticas e/ou nutricionais e, em geral, não simulam as alterações metabólicas e histológicas comumente vistas em pacientes com NAFLD. Em nosso grupo, foi proposto um novo modelo de NAFLD. Camundongos C57BL/6 alimentados com dieta rica em gordura (High Fat - HF) demonstraram alterações metabólicas e histológicas sugestivas de NAFLD. O objetivo do presente trabalho foi comparar alterações histológicas hepáticas presentes nestes camundongos com as alterações observadas em pacientes obesos. Amostras de fígados de pacientes obesos e de camundongos alimentados com a dieta HF foram utilizadas. Os tecidos hepáticos foram corados em Hematoxilina & Eosina e Picrossírius Red para avaliação das alterações hepáticas (esteatose, balonização, inflamação, corpúsculos de Mallory-Denk e fibrose). Além disso, foi realizada imunoistoquímica para avaliação da presença de células estrelares ativadas e de células progenitoras hepáticas, células envolvidas na fibrose e no desenvolvimento de carcinoma hepatocelular, respectivamente. Os resultados demonstraram que os fígados de todos os pacientes obesos exibiram esteatose macrovacuolar, balonização hepatocelular, inflamação lobular e fibrose perissinusoidal, o que caracterizou estes pacientes como portadores da NAFLD. As mesmas alterações foram observadas em fígados de camundongos alimentados com a dieta HF. As células estrelares ativadas foram observadas em todos os pacientes obesos, assim como em camundongos de dieta HF. As células progenitoras hepáticas foram observadas na maioria dos pacientes obesos. O fígado de todos os camundongos alimentados com dieta HF exibiram células progenitoras hepáticas. A partir dos dados obtidos, pode-se concluir que fígados de camundongos alimentados com dieta HF exibem alterações histológicas hepáticas similares às observadas em pacientes obesos. Isto abre perspectivas para a utilização do modelo proposto em estudos que busquem elucidar os mecanismos envolvidos na patogênese da NAFLD.
Nonalcoholic Fatty Liver Disease (NAFLD) is a chronic liver disease ranging from simple steatosis to nonalcoholic steatohepatitis. The progression to cirrhosis and hepatocellular carcinoma has been reported. The NAFLD shows histological features similar to alcohol-related liver disease (steatosis, lobular inflammation, fibrosis and Mallory-Denk bodies), but affects individuals with no history of excessive alcohol consumption. The NAFLD is a major chronic hepatic disease in the world, and obese individuals represent the majority of cases of the disease. The mechanisms involved in the progression of steatosis to steatohepatitis are not well understood. In this regard, murine models of NAFLD have been frequently used for elucidation of these mechanisms. Most available models are the result of genetic or nutritional modifications, and generally do not mimic metabolic and histologic changes commonly seen in patients with NAFLD. In our group, we have proposed a new model of NAFLD. Mice fed high fat diet (HF diet) demonstrated metabolic and histological features suggestive of NAFLD. The aim of this study was to compare liver histological alterations present in these mice with the changes observed in obese patients. Samples of livers of obese patients and mice fed HF diet were used. For assessment of liver alterations, such as steatosis, ballooning, inflammation, Mallory- Denk bodies and fibrosis, tissues were stained with hematoxylin & eosin and picrossirius red. In addition, the presence of activated stellate and progenitor liver cells was estimated using immunohistochemistry. The results show that the livers of all obese patients exhibited macrovesicular steatosis, hepatocellular ballooning, perisinusoidal fibrosis, and lobular inflammation, which characterized these patients with NAFLD. Similar changes were observed in livers of mice that fed the HF diet. Activated stellate cells were observed in all obese patients as well as in mice HF. Hepatic progenitor cells were observed in most obese patients. The liver of all animals fed the HF diet exhibited liver progenitor cells. From the data obtained, it can be concluded that livers of mice fed with HF diet exhibit liver abnormalities similar to those observed in obese patients. This opens perspectives for the use of the proposed model in studies that seek to elucidate the mechanisms involved in the pathogenesis of NAFLD.

A Paracoccidioidomicose é uma micose sistêmica humana causada pelo fungo dimórfico, Paracoccidioides brasiliensis, que acomete, principalmente, indivíduos adultos do sexo masculino. O presente estudo propôs a padronização do modelo de infecção com P. brasiliensis pela via intratorácica em camundongos BALB/c. Este estudo foi monitorado pela detecção do P. brasiliensis através da contagem de unidades formadoras de colônia e pela presença de DNA do fungo nos pulmões dos animais infectados em diferentes pontos pósinfecção (2o, 7o, 15o, 30o, 45o, 60o e 90o dias) e a taxa de sobrevida dos camundongos. Além disto, foram avaliados alguns parâmetros imunológicos como a produção de óxido nítrico, TNF-alpha, IFN-gama, e IL-10 por células presentes no lavado intratorácico, contagem total e diferencial do número de células do lavado intratorácico, o estudo histopatológico dos pulmões e a detecção de anticorpos específicos anti-P. brasiliensis nos pulmões e no soro. Os resultados mostram um aumento gradual do número de colônias e de DNA de P. brasiliensis nos pulmões. Até o 15o dia após a infecção pode ser observado um aumento na produção de óxido nítrico e IFN-gama pelas células do lavado intratorácico, bem como um aumento do número total de células e da porcentagem de leucócitos mononucleares. A partir do 30o dia após a infecção observa-se um aumento de anticorpos específicos (IgG1) no soro e no pulmão, um aumento da produção de IL-10 e TNF-alpha pelas células do lavado intratorácico e conseqüente diminuição da produção de IFN-gama e óxido nítrico. Além disso, observa-se um aumento da porcentagem de células polimorfonucleares no lavado. No estudo histopatológico pode ser constatado um aumento gradual no tamanho e complexidade dos granulomas presentes nos cortes histológicos. Os camundongos utilizados no estudo de sobrevida começaram a morrer no 60o dia após a infecção. Os resultados mostram uma resposta inicial do hospedeiro com um perfil Th1 mudando durante a infecção para uma resposta Th2 que leva ao óbito dos camundongos BALB/c.
Paracoccidioidomycosis or South American blastomycosis, is a chronic granulomatous human male infection caused by the Paracoccidioides brasiliensis. The present study it considered the standardization of the model of infection with P. brasiliensis for the intrathoracic route in BALB/c mice. This study was monitored by the detection of the P. brasiliensis through the counting of colony forming units and by the presence of DNA of fungi in the lungs of the infected animals in different points (2, 7, 15, 30, 45, 60 and 90 days) and the survival rate of the mice. Moreover, some immune parameters had been evaluated as the nitric oxide production, TNF-alpha, IFN-gamma, and IL-10 for cells in the intrathoracic washed, total and distinguishing counting of cells of the intrathoracic washed, the lung histopathology and the detection of specific antibodies anti-P. brasiliensis in the lungs and serum. The results show a gradual increase of the number of colonies and P. brasiliensis DNA in the lungs. Until 15 day after the infection can be observed an increase in the nitric oxide production and IFN-gamma for the cells of the washed, as well as an increase of the total number of cells and the percentage of mononuclear. From 30 day after the infection observes an increase of specific antibodies (IgG1) in the serum and the lung, an increase of the production of IL-10 and TNF-alpha for the cells of the washed and consequent reduction of the IFN-gamma production and nitric oxide. Moreover, observed an increase of the percentage of cells polimorphonuclear in the washed. In the histopathology it can be evidenced a gradual increase in the size and complexity of granulomas in the cuts. The mice used in the survival study had started to die in 60 day after the infection. The results show an initial reply of the host with a Th1 profile moving during the infection for a Th2 reply that leads to the death of the BALB/c mice.

Full textInflammatory bowel disease (IBD) in humans is a complex etiology of chronic reactions. It is an exacerbated immune reaction and depends on the microflora. The nervous system interacts with the intestinal immunity of a bidirectional fashion. Clinical reports and few experimental findings point to a link between depressive disorders and inflammatory bowel disease, suggesting neuroimmunological interaction in the pathogenesis of this process. Also, treatment of inflammatory bowel diseases (Crohn\'s disease DII- and Ulcerative Colitis) with antidepressants in murine models of colitis have pointed to positive results in reducing inflammation. The mechanism of inflammation in IBD and the involvement of the nervous system or modulation of this process by the use of antidepressants is not yet fully elucidated. This study aimed to study the effect of amitriptyline in a murine model of colitis. Colitis was induced in C57BL / 6 mice by Dextran Sodium Sulfate (DSS) and amitriptyline (AMT) were orally administered in a prophylactic or therapeutic regimen. We evaluated the AMT dose in the tail suspension test (TST), the accumulation of neutrophils by myeloperoxidase activity (MPO), oxidative burst, survival curve, bowel histopathology, disease activity by clinical symptoms, depletion of intestinal mucus, colon and inflammatory cytokines in the serum phenotype of CD4+ T lymphocytes, CD8+ and CD14+ monocytes. Results: The dose of AMT (200 μg / ml) and treatment regimens used herein are able to prevent or decrease the pathology of colitis, clinical signs (weight gain (%), colon weight and length) and mortality animals in the therapeutic model inflamed group and treated with AMT. MPO activity, circulating levels of IL- 1 β, IL- 6 and TNF- α were reduced in both experimental protocols (prophylactic and therapeutic). Conclusions: This study included a prolonged period of treatment, as antidepressants are known to be effective in humans after several weeks or months of limitation, and confirmed the effectiveness of oral administration route, since antidepressants are generally administered orally to humans. This treatment scheme has improved potential anti-inflammatory AMT in reducing DSS colitis in mice based on the study parameters
