On the cover: Immunohistochemical staining of the C5a receptor in the mouse kidney subjected to renal ischemia-reperfusion. The C5a receptor is expressed on infiltrating neutrophils. Intriguingly, also tubular epithelial cells express the C5a receptor. De Vries et al. Complement factor C5a mediates renal ischemia-reperfusion injury independent from neutrophils. 3883.)
