Secreted C-type lectins protect the intestinal epithelium from Gram-positive bacteria; this study shows that for the C-type lectin RegIIIα, bacterial killing occurs in a two-step process whereby the lectin first binds to bacterial peptidoglycans then oligomerizes on the bacterial membrane to form a permeabilizing pore.
