Blimp1 Prevents Methylation of Foxp3 and Loss of Regulatory T Cell Identity at Sites of Inflammation

2018

Summary Foxp3+ regulatory T (Treg) cells restrict immune pathology in inflamed tissues; however, an inflammatory environment presents a threat to Treg cell identity and function. Here, we establish a transcriptional signature of central nervous system (CNS) Treg cells that accumulate during experimental autoimmune encephalitis (EAE) and identify a pathway that maintains Treg cell function and identity during severe inflammation. This pathway is dependent on the transcriptional regulator Blimp1, which prevents downregulation of Foxp3 expression and “toxic” gain-of-function of Treg cells in the inflamed CNS. Blimp1 negatively regulates IL-6- and STAT3-dependent Dnmt3a expression and function …

Antigen-dependent competition shapes the local repertoire of tissue-resident memory CD8+ T cells.

2016

Muschaweckh et al. show that antigen presentation in the skin regulates the generation of tissue-resident memory T (TRM) cells by orchestrating local competition of antiviral CD8+ T cells, revealing a mechanism to fine-tune the repertoire of regional pools of TRM cells.
