Cieslak, Agata. "Normal and pathological mechanisms of TCRα/δ locus rearrangement in thymic lymphopoiesis". Thesis, Sorbonne Paris Cité, 2016. http://www.theses.fr/2016USPCB112.
Maturation of T lymphoid cells is a highly regulated process where ordered thymic rearrangements at the TCRδ, TCRy, TCRβ and finally TCRα loci determine the development into either yδ or αβ T-cell lineages. Somatic rearrangements of V, (D), and J gene segments of TCR loci involve RAG1/2 proteins, RSS sequences juxtaposing V, D, and J genes segments and regulatory elements (enhancers) providing a cis-regulation of this process. The control of the V(D)J recombination is achieved through various mechanisms including epigenetic modifications, involvement of transcription factors and RSS conformation/sequence. In this work, we show that TCRδ rearrangements are strictly ordered in Humans. The first Dδ2-Dδ3 rearrangement occurs at ETP (Early T-Cell Precursor) stage CD34+/CD1a-/CD7+dim, and always precedes Dδ2-Jδ1 rearrangement. In-silico analysis of the locus identified a key binding site for a transcription factor RUNX1 in close proximity to the Dδ2-23RSS heptamer in human, but not in mice. The RUNX1 recruitment at this site in immature CD34+/CD3- thymocytes increases binding affinity of RAG1/2 proteins. This work identifies an original cofactor of human VDJ recombination. A set of comprehensive epigenetic analysis conducted within the Europeen Blueprint project on human thymic subpopulations allowed as to establish that the TCRα enhanceosome (Eα), as in mice, is already formed from the earliest stages of thymopoiesis without being able to be activated before the end of β-selection. Our preliminary results suggest that HOXA homeobox proteins (including HOXA9) suppress the activity of the Eα (thus TCRα rearrangements) by interacting with the transcription factor ETS1 via their homeodomains. Induced by β-selection HOXA repression results in the chromatin opening of the Vα/Jα gene segments through TCRα activation. These finding shed new light on the so far unexplained shift observed between the formation of Eα enhanceosome at a very immature stages and its activation at a much later developmental stages

[FR]Il est bien illustré que la génération périnatal de Treg est le principal mécanisme responsable du maintien de la tolérance immunitaire fœtale qui se développe suite à l'exposition aux antigènes maternels non-hérités (NIMA). De plus, la présence de Tregs spécifiques des NIMA dans l'utérus des femmes enceintes favorise la capacité de reproduction en renforçant la tolérance maternelle aux mêmes antigènes paternels exprimés par le fœtus pendant les grossesses de prochaine génération. Cependant, la raison pour laquelle la lignée des cellules T fœtales est biaisée en faveur de la tolérance immunitaire est mal comprise. Chez la souris, en raison du manque d'expression de la désoxynucléotidyl transférase terminale (TdT), les cellules T néonatales ont un répertoire de TCR moins diversifié. Ceci est connu pour limiter leur spécificité et augmenter leur affinité pour les complexes CMH / peptide. Au début du présent travail, nous avons émis l'hypothèse que l'expression de TCRs de haute affinité pourrait être la raison qui force le développement de Treg spécifiques chez les nouveau-nés. Nous avons plus particulièrement entrepris notre étude dans le but d'étudier les mécanismes sous-jacents au développement de Tregs spécifiques des NIMA chez la souris pendant la période périnatale. En utilisant le modèle de souris hétérozygotes pour 2W1S-OVA+ dans lequel l'antigène 2W1S a été transformé en NIMA pour la moitié de la progéniture, nous avons observé une fréquence accrue de Tregs spécifiques de 2W1S chez les animaux exposés au NIMA. De plus, nous avons également observé que les Treg NIMA-2W1S dérivés de la périphérie avaient un répertoire de TCRs moins diversifié et étaient phénotypiquement distincts des Tregs spécifiques de SELF-2W1S dérivés du thymus. Afin de déterminer si le manque de diversité était responsable du développement de Tregs néonataux spécifiques de NIMA, nous avons généré des souris transgéniques où l'expression de TdT était appliquée dans les cellules T avant la naissance. Nous avons constaté que le TdT transgénique ajoutait une diversité de TCR clonale, mais n'empêchait pas le développement de clones de cellules T avec un répertoire TCR de type néonatal et ne modifiait pas la fréquence des Treg néonataux spécifiques du NIMA. Au contraire, l'expression de TdT a augmenté de manière significative la génération de Tregs spécifiques de SELF-2W1S à des niveaux similaires à ceux des Treg spécifiques de NIMA-2W1S. Prises ensembles, nos données indiquent que les voies de développement du répertoire des Tregs néonataux spécifiques de NIMA et SELF sont différentes en termes d'induction et de maintien de la tolérance néonatale.

"Origin of somatic mutations in lymphoid cancers : role of the V(D)J recombinase Breakage-fusion-bridge events trigger complex genome rearrangements and amplifications in developmentally arrested T cell lymphomas End donation errors at antigen receptor loci trigger genome-wide instability in ATM-deficient T cell lymphomas." Thesis, Sorbonne Paris Cité, 2018. http://www.theses.fr/2018USPCB057.
Lymphoid cancers frequently harbor chromosomal aberrations. Abnormal V(D)J recombinase (i.e RAG endonuclease) activity is thought to promote genomic instability in lymphocytes, while DNA damage response (DDR) factors such as Ataxia-telangiectasia mutated (ATM) and p53 have been shown to suppress aberrant chromosomal rearrangements and lymphomagenesis. During my thesis, to test the relative contribution of these factors in shaping the pattern of somatic mutations in lymphoma genome, I performed whole genome and transcriptome sequencing of several genetically modified mouse lymphoma models in which the activities of RAG and DDR were perturbed. In a first study, I have identified specific recurrent genomic lesions caused by off-target RAG activity and, more surprisingly, a unique pattern of aberrant rearrangements occurring in the absence of RAG. I provided evidence that, in the absence of RAG, Breakage-Fusion-Bridge triggers instability and amplification of a genomic region of several megabases leading to the overexpression of multiple known and putative cancer genes. Importantly, I also showed that this region is found amplified in a subset of human leukemia. Using additional animal models in which blocked T cell differentiation due to the absence of RAG was rescued by the expression of a transgenic T cell receptor, I could demonstrate that both developmental stage and RAG activity determine T cell lymphoma genome landscapes and mediate malignant transformation through distinct oncogenic paths. In addition, I have established the first genome-wide analysis of ATM-deficient T-cell lymphomas and identified a high number of aberrations localized at antigen receptor loci and ectopic locations in these tumors. My results suggest that, in the absence of ATM, aberrantly resolved RAG-induced DNA breaks at antigen receptor loci trigger massive complex rearrangements spreading to ectopic locations and affecting cancer genes. Overall, my studies provide new insights into the mechanisms of somatic mutations arising in lymphoid cancers in the context of aberrant V(D)J recombination and DDR

T-ALL is a lymphoid neoplasia that accounts for 10-15% of pediatric ALL and 25% of adult ALL. Alarmingly, and despite indisputable success achieved in treatments its incidence is increasing and its prognostic remains pejorative. Survival rate outcome depend notably on a better understanding in pathogenic mechanisms. In this context, the thesis work has been the following: 1) Based on the observation that rare chromosomal SJ keep on recombining in cis using V(D)J recombination, we hypothesized that episomal SJ (ESJ) still remain reactives and can undergo genomic reintegration. We show that mechanistically, ESJ efficiently rearrange in trans and that the cRSS, the sequences targeted in oncogenic chromosomal translocations, are good ESJ integration sites. Moreover, we demonstrate the presence of ESJ reintegration events in vivo and estimate their frequency to ~1/104-6. In conclusion, ESJ reintegration is a potential mechanism of oncogenic deregulation. 2) Conventional and illegitimate V(D)J recombination events (e. G. Translocations) are ordered during lymphocyte development. Based on our knowledge on chromosomal translocation mechanisms, we determine the kinetics of a subset of oncogenic activations acquired during the transformation process in a T-ALL patient’s leukemic cells. Moreover, we identified up to 10 independent oncogenic events in this patient, illustrating the multi-hit characteristic of T-ALL. Finally, the oncogenic event’s functional impact suggests that cMyc play an important role in the particularly aggressive features of the T-ALL developed by this patient

T lymphocytes express at their surface an antigen receptor composed by a~ or y8 chains. A TCRa chains are encoded by a variable (V), ajoining (J) and a constant (C) segments which are under the of the control of a specific recombination mechanism called "V(D)J recombination". The VJ combinatorial diversity is unknown and the current state of molecular technology does not allow us to perform an analysis of aIl putative VJ combination or to estimate the frequencies of the functional VJ in mice. To overcome this difficulty we defined a mathematical model fitting experimental data. This model gives new insights on the mIes controlling the use of the V and the J genes and provides a dynamic ca1culation of the VJ combinations. The model proposes an accessibility of the TRAlTRD locus by sûccessive windows of different sizes and with different speed of progression. Furthermore, a possibility of successive secondary rearrangements was introduced. Ln parallel, an experimental analysis of the VJ combination has been performed in humans. From this analysis, the VJ combination profiles are ca1culated and used to validate our simulation program. Ln the future, the model may be use to analysis the variations between sound or altered repertoire

Resumo: No presente estudo foi investigado um tipo de instabilidade específica dos linfócitos que, segundo dados de literatura, pode estar relacionado com o desenvolvimento de neoplasias "de novo" ou associadas ao aparecimento de neoplasias secundárias. Esta instabilidade estudada é definida através da freqüência de rearranjos que ocorrem entre o segmento V no receptor de células T no locus gamma (7p14-15) e do segmento J do receptor de células T no locus beta (7q 35). Desta forma, os objetivos deste estudo foram: 1) utilizando o gene lnorido Vy/JJ3como marcador, estudar a instabilidade gênica induzida pela quimioterapia antineoplásica em pacientes pediátricos portadores de leucemia linfocítica aguda ou tumores sólidos; 2) estudar o grau de reversibilidade desta instabilidade após o final da exposição aos agentes quimioterápicos e 3) demonstrar a validade da abordagem de estudo da recombinação, avaliando os produtos da "nested PCR" de DNA genômico dos pacientes em gel de poliacrilamida, posteriormente revelado pela prata (abordagem ainda não descrita na literatura para o estudo do gene em questão). Foram analisadas 210 amostras de DNA de indivíduos agrupados desta maneira: sem neoplasia- 30 indivíduos, 90 pacientes com LLA ( 15 pré Qt, 15 com QT 3-6 meses e 15 com 9 a 12 meses, 15 pacientes após término entre 6 e 12 m, 15 após 2 a 4 anos e 15 após 5 anos ou mais) e 90 pacientes com Tumor Sólido, também subagrupados da mesma forma que os pacientes com LLA. Todos os 210 pacientes foram classificados com resultado positivo ou negativo para o rearranjo, de acordo com a presença ou ausência da banda esperada após a segunda PCR Para cada indivíduo foram estudadas 6 diferentes quantidades de DNA (525ng, 350,175,35,17.4, e 8.75) e, em cada uma delas, chamamos de positivo ou negativo para o rearranjo de acordo com 'a presença ou ausência da banda visualizada no gel revelado. Foi determinada a média da freqüência do rearranjo Vy/Jp para cada grupo. O grupo de pacientes durante a quimioterapia foi comparado com a média da freqüência dos rearranjos pré e pós-quimioterapia separadamente para o grupo de LLA e TS. As médias foram comparadas utilizando-se o teste de Kruskal-Wallis. As comparações múltiplas foram feitas através do método Tukey-HSD. A média da fteqüência de rearranjos foi de 10,2/105 células para os pacientes com LLA que estavam expostos aos quimioterápicos no período de 3 a 6 meses e para o grupo em tratamento entre 9 a 12 meses foi de 13,8/105. Para o grupo controle (30 indivíduos) e para o grupo com LLA pré-tratamento os valores foram 1,3/105e 3,11105. O estudo estatístico comparando grupos -controle, LLA pré-QT e LLA durante QT - mostrou tratar-se de valores altamente significativos (p < 0,001). No grupo de pacientes com Tumor Sólido, a média da freqüência de rearranjos durante o tratamento foi de 9,2 e 9,11105 células respectivamente para 3 a 6 meses de tratamento e 9 a 12 meses. O grupo controle, sem neoplasia, foi o mesmo descrito acima e a média de rearranjo foi de 1,3/105 e para os TS pré-quimioterapia foi de 0,6/105 células. Novamente o estudo estatístico comparando grupos -controle, TS pré QT e TS durante QTmostrou tratar-se de valores altamente significativos(p < 0,002). Desta forma pode-se concluir que: 1) o método utilizando gel de poliacrilamida corado pela prata pode ser substituído pelo gel de agarose corado com brometo de etídio e hibridizado pela técnica de Southem Blot, sem prejuízo dos resultados e com a vantagem de ser mais rápido, de menor custo e da não-necessidade de utilização de material radioativo e 2) os resultados do estudo indicam que os pacientes apresentaram instabilidade gênica onde a presença do gene ln'brido Vy/Jf3pôde ser observada em freqüência mais elevada durante a fase de tratamento com quimioterapia
Abstract: The ftequency of the hybrid Vy/J[3 trans-rearrangement in peripheral blood lymphocytes (PBL) was analysed in a transversal study of pediatric patients (n=210) with acute lymphoblastic leukemia (ALL) and solid tumours (ST). DifIerent amounts of DNA were used as template for a nested PCR in order to evaluate the ftequency ofhybrid Vy/J[3 genes, using silver-stained gels. The ftequency of the rearrangement was evaluated in groups before, during and afier therapy. A great1y increased ftequency of Vy/J[3transrearrangement was found in PBL of both groups of patients during exposure to chemotherapeutic agents as compared to patients before chemotherapy. In patients that had finished treatment, the ftequency of the rearrangement feUprompt1yto the baseline levels in ST but showed a slow decrease in ALL, where increased levels could be found until 4 years afier the end oftreatment. We hypothesize that the chemotherapeutic agents are able to induce the Vy/J[3trans-rearrangement, but this is transient in most cases. It remains to be determined the exact relation between the persistence of the rearrangement and the occurrence of secondary leukemia

The diversity of antigen receptors is composed from the recombination of their V, D and J segments. The mecanisms underlying the regulation of the recombination are poorly understood, but rely on the accessibility of the DNA to the V(D)J recombinase. We showed in this work that the two T cell receptors TCR J alpha are not randomly, but rather coincidentally rearranged in a given T cell. This coincidence relies, in part, on the presence of <> (TEA), a cis regulatorygenetic element located upstream of the TCRJA cluster

This doctoral thesis is dedicated to a manuscript belonging to the Berlin National Library : D-Bds Mus. Ms. Autogr. J. V. Meder 1. Although it is classified among highly valuable sources since 1850, this score of a St. Matthew Oratorio-Passion hasn't been the subject of any research yet. Though, the title page being lost, the composer as well as the composition place and date of the unique remaining source were unknown. Basing on the analysis of the source (paper, inks and handwritings), this thesis sets out how the three versions forming this manuscript have been updated. Considering that the Passion has been performed in Riga throughout the 18th century, the study of the historical context of the work in that city, revealed as the actual place of composition by the watermarks, allowed to determine the meaning of the apocryphal versions in comparison to the original one. Lastly, the analysis of the materials characteristics in the perspective of the sources of that time, as well as the dating of the chorals melodies in the manuscript, permitted the final identification of the Actus Musicus de Passione Jesu Christi, composed by Johann Valentin Meder in 1716. This research restores to favour a Passion that is wrongly identified and edited in current publications (MGG, New Grove or Das Chorwerk edition), making it therefore the prelude to a critical edition

An individual’s adaptive immune system needs to face repeated challenges of a constantly evolving environment with a virtually infinite number of threats. To achieve this task, the adaptive immune system relies on large diversity of B-cells and T-cells, each carrying a unique receptor specific to a small number of pathogens. These receptors are initially randomly built through the process of V(D)J recombination. This initial generated diversity is then narrowed down by a step of functional selection based on the receptors' folding properties and their ability to recognize self antigens. Upon recognition of a pathogen the B-cell will divide and its offsprings will undergo several rounds of successive somatic hypermutations and selection in an evolutionary process called affinity maturation. This work presents principled probabilistic approaches to infer the probability distribution underlying the recombination and somatic hypermutation processes from high throughput sequencing data using IGoR - a flexible software developed throughout the course of this PhD. IGoR has been developed as a versatile research tool and can encode a variety of models of different biological complexity to allow researchers in the field to characterize evermore precisely immune receptor repertoires. To motivate this data-driven approach we demonstrate that IGoR outperforms existing tools in accuracy and estimate the sample sizes needed for reliable repertoire characterization. Finally, using obtained model predictions, we show potential applications of these methods by demonstrating that homozygous twins share T-cells through cord blood, that the public core of the T cell repertoire is formed in the pre-natal period and finally estimate naive T cell clone lifetimes in human

Guicherd, Thibault. "Essai sur la genèse de la théorie de la concurrence monopolistique d' Edward H. Chamberlin." Thesis, Lyon, 2017. http://www.theses.fr/2017LYSE2148.
This thesis studies the genesis of Edward H. Chamberlin’s monopolistic competition theory. The originality of our work is based on a detailed story, emancipating itself from the usual approach which considers our author’s work and J. Robinson’s imperfect competition as alike without questioning their differences. The thesis develops the version given by Chamberlin in which he insists on the importance of duopoly and product differentiation along with the independence between his theory and the English post-Marshallian debate. Thanks to the study of his Ph. D thesis, which embodies the first version of monopolistic competition, the study of unpublished essays and correspondence and his published writings, we provide new elements sometimes attesting Chamberlin’s version and sometimes moderating its relevance. Specific attention has been given to the duopoly question and its role in monopolistic competition theory
