Lack of PD-L1 signaling leads to altered intestinal histology. A, Histology of the small intestine from isotype and anti-PD-L1-treated C57BL/6 and iFABP-tOVA mice 5–7 days posttransfer of T cells. Tissues were fixed and processed for H&E staining. Images at a magnification of ×20 show representative histology of the small intestine for each condition. B, Images at a magnification of ×40 show representative histology of intestinal villi for each condition with apoptotic epithelial cells indicated (arrowhead).
