Programmed cell death protein 1 (PD-1) regulates metabolic activity of regulatory T cells in ischemia-induced acute kidney injury.
It is demonstrated that PD-1 knockout mice have worse renal function after IRI when compared to wild-type mice, and the metabolic vulnerability of PD-1-deficient Tregs is revealed, highlighting the critical role of PD-1 in Treg-mediated nephroprotection.
