Development of type 1 diabetes mellitus T1D in NOD mice follows transcriptional activity of thymocytes and peripheral T lymphocytes

Project description:Non-obese diabetic (NOD) mice feature pancreatic infiltration of autoreactive T lymphocytes as early as 1 month of age, which destruct insulin-producing beta-cells to finally emerge autoimmune diabetes mellitus (T1D) within 8 months. In view, we hypothesized that during the development of T1D, transcriptional modulation of immune reactivity genes may occur as thymocytes mature toward peripheral T lymphocytes. Transcriptome of thymocytes and peripheral CD3+ T lymphocytes from pre-diabetic or diabetic mice analyzed through microarray hybridizations allowed observation of 3,586 differentially expressed genes. Hierarchical clustering grouped mice according to age/T1D onset and genes to their ontology. Transcriptional activity of thymocytes toward peripheral T lymphocytes unraveled sequential participation of genes involved with CD4+/CD8+ T cell differentiation (Themis), tolerance induction (Foxp3), apoptosis (Fasl) to soon after T cell activation (IL4), while the emergence of T1D coincided with the expression of cytotoxicity (Crtam) and inflammatory response genes (Tlr) by peripheral T lymphocytes.

mRNA expression profile of medullary thymic epithelial cells-mTECs- of BALBc mice

Project description:The medullary thymic epithelial cells (mTECs) express virtually all autoantigens of the body. This phenomenon was then termed promiscuous gene expression (PGE). A large set of autoantigen genes (but not all) is controlled by the transcriptional modulator Autoimmune regulator (Aire) in mTECs. These autoantigens represent all tissues and organs in the thymus and it is implicated in the negative selection of autoreactive thymocytes, and consequantly preventing autoreactive autoimmune reactions and autoimmune diseases (e.g. type 1 diabetes mellitus, systemic lupus erythematosus). Thus, we are looking at gene expression in thse cells because it is very important to better understand the molecular basis of central immune tolerance to normal tissues and organs. The aim of this study is to evaluate the possible link between the expression of the transcriptional regulator Aire, the genetic background of mouse strains and the promiscuous gene expression in mTECs.

MicroRNA profiling of mouse thymus from diabetic and pre-diabetic NOD (non obese diabetic) animals

Project description:The current project is within the range of molecular immunogenetic auto immune diseases and refers to the comparative study of promiscuous gene expression of tissue-specific antigens (TSAs) in the thymus of NOD mice line (non obese diabetic) who plays the auto-immune diabetes mellitus type 1, during the transition from state pre-diabetics to diabetics. Use the technology of oligo arrays to investigate the expression of miRNAs and cDNA microarrays to investigate the expression of genes encoding the messenger RNAs including TSAs (tissue specific antigens).

Assessing the role of microRNAs in post-transcriptional control of thymocytes and peripheral lymphocytes in NOD mice

Project description:As early as one month of age, non-obese diabetic (NOD) mice feature pancreatic infiltration of autoreactive T lymphocytes, which destruct insulin-producing beta cells, leading to autoimmune diabetes mellitus (T1D) within eight months. Thus, we hypothesized that during the development of T1D, the transcriptional modulation of immune reactivity genes, as well as, modulation of microRNAs (miRNAs) may occur during thymocytes mature into peripheral CD3+ T lymphocytes. Our aim is to analyze the transcriptional modulation of mRNA and microRNAs during development of thymocytes into peripheral CD3+ T lymphocytes in the context of the emergence of T1D.

Transcriptional profile in TECs

Project description:Cortical 1.4C18 and medullary 3.10 TEC lines (mTEC) were cultured in 10% fetal bovine serum-supplemented RPMI 1640 medium at 37 ?C in a 5% CO2 atmosphere. Confluent cultures of 3.10 mTEC cell line were cultured during 72 h in RPMI medium as above mentioned and total RNA was extracted using the mirVana kitM-. (Ambion, Austin, TX, USA).
