text_1: The RANK-RANK-Ligand (RANKL) pathway is involved in the development of Aire-expressing medullary thymic epithelial cells (mTECs).
text_2: Here we demonstrate a novel role for a CD4+3− inducer cell population, previously linked to development of organized secondary lymphoid structures and maintenance of T cell memory in the functional regulation of Aire-mediated promiscuous gene expression in the thymus.
