WebDuring thymus organogenesis, these functionally distinct sub-lineages are thought to arise from a common thymic epithelial progenitor cell (TEPC). However, the mechanisms controlling cTEC and mTEC production from the common TEPC are not… Vis mere Thymus function depends on the epithelial compartment of the thymic stroma. Web4 nov. 2015 · In this study, in mouse thymus, we analyze late-stage mTEC development in relation to the timing and requirements for Aire and involucrin expression, the latter a marker of terminally differentiated epithelium including Hassall's corpuscles. We show that Aire expression and terminal differentiation within the mTEC lineage are temporally ...

Maturation of mTEC leads to expression of high levels of MHCII, CD80, autoimmune regulator Aire and tissue restricted antigens (TRAs). Expression of Cathepsin L and Cathepsin S is also typical for mTEC, because of participation of these proteases in the negative selection of T cells. Representative surface markers are UEA-1 and CD80. After maturation continue mTEC to the terminal differentiation stage, which is accompanied by loss of specific maturation factors (MHC… WebThe LIOTHYRONINE and B lymphocytes (T and BORON Cells) are involved is to acquired or antigen-specific immune respond given that they are the only cells to the organism able to recognize and respond specifically to each antigenic epitope.

Webselection in the thymus, whereby the developing T cell is exposed to a range of self-peptide-MHC complexes. This process, referred to as negative selection, results in the deletion from the T cell repertoire of cells with high affinity for self-peptide-MHC complexes (Klein et al., 2009). The range of self-peptides to which the developing T ...
