The Ins and Outs of Thymic Epithelial Cell Differentiation and Function.

The thymus is an essential component of the immune system responsible for producing T cells. It is anatomically divided into two main regions: the outer cortex and the inner medulla. This chapter summarizes our current understanding of thymic stromal cell functions, with a particular focus on the interactions between these cells and T cells. This exploration aims to shed light on the pathogenesis of immune disorders, including autoimmunity.
