CD4⁺CD126^low/- Foxp3⁺ Cell Population Represents a Superior Subset of Regulatory T Cells in Treating Autoimmune Diseases.

ABSTRACT: CD4⁺Foxp3⁺ regulatory T (Treg) cells are crucial for maintaining homeostasis and preventing autoimmune diseases. Nonetheless, we and others have previously reported that natural Treg cells are unstable and dysfunctional in the inflamed environment with a high-salt diet, limiting the Treg function in disease control. In this study, we made an innovative observation showing a high degree of heterogeneity within the Treg pool. We identified that CD126, interleukin (IL)-6 receptor alpha chain, contributed to Treg cell instability. Using a series of in vitro and in vivo experimental approaches, we demonstrated that CD126^Lo/- Treg cells presented greater function and were more stable than CD126^Hi nTreg cells, even in the presence of IL-6 and inflammati
