Treg and Th cells are under transcriptional modulation via cytokine mediated control of a Nfil3 protein that serves to block FOXp3 expression.DR Guerra verifies the evidence in the data from a recent paper: Experimental & Molecular Medicine volume 51, Article number: 80 (2019) that demonstrated Inhibition of the TGF-β signaling pathway led to increased Nfil3 expression which blocked Foxp3 transcription via SMAD3.
This is an important contribution to the T lymphocyte literature as it points to the proximal and distal modulation of T cell lineage differentiation, thus focusing attention to potential pharmacotherapeutic and immunoepigenetic mechanisms to control inflammation in diseases such as IBD while simultaneously suggesting strategies to reorganize the T cell profile to destroy tumors.
