TGF-beta treatment modulates PD-L1 and CD40 expression in proximal renal tubular epithelial cells and enhances CD8 cytotoxic T-cell responses.


BACKGROUND/AIM TGF-beta expression is increased in immune-mediated and fibrotic renal diseases and modulates the tubulointerstitial T-cell response. We examined whether TGF-beta changes the expression of PD-L1 and CD40 in the renal proximal tubular epithelial cell (TEC), and whether the activation of CD8(+) cytotoxic T cells (CTLs) is influenced by TGF-beta… (More)
