Article Synopsis
  • This study explores how regulatory T cells (Tregs) behave in inflammatory bowel diseases like Crohn's disease, focusing on their metabolic processes that impact gut homeostasis.
  • Researchers used various advanced techniques (like electron microscopy and mass cytometry) to analyze Tregs' cellular structures and functions in humans and murine models of colitis.
  • Key findings show that inhibiting a specific protein (VDAC1) disrupts Treg metabolism and increases sensitivity to inflammation, while manipulating metabolic pathways can restore proper Treg function and potentially inform new therapeutic strategies for inflammatory diseases.

Background & Aims: The incidence of Crohn's disease (CD) continues to increase worldwide. The contribution of CD4 cell populations remains to be elucidated. We aimed to provide an in-depth transcriptional assessment of CD4 T cells driving chronic inflammation in CD.

FOXP3+ Tregs are expanded within the inflamed intestine of human Crohn's disease, yet FOXP3-mediated gene repression within these cells is lost. The polycomb repressive complexes play a role in FOXP3 target gene regulation, but deeper mechanistic insight is incomplete. We have now specifically identified the polycomb-repressive complex 1 (PRC1) family member, BMI1 in the regulation of a proinflammatory enhancer network in both human and murine Tregs.

T cell lineage decisions are critical for the development of proper immune responses to pathogens as well as important for the resolution of inflammatory responses. This differentiation process relies on a combination of intrinsic and extrinsic factors converging upon epigenetic regulation of transcriptional networks relevant to specific T cell lineages. As these biochemical modifications represent therapeutic opportunities in cancer biology and autoimmunity, implications of writers and readers of epigenetic marks to immune cell differentiation and function are highly relevant.

Regulatory T (Treg) cells expressing the transcription factor FOXP3 play a pivotal role in maintaining immunologic self-tolerance. We and others have shown previously that EZH2 is recruited to the FOXP3 promoter and its targets in Treg cells. To further address the role for EZH2 in Treg cellular function, we have now generated mice that lack EZH2 specifically in Treg cells (EZH2FOXP3).
