Defensin HNP-5 (HD-5) is a human α-defensin secreted primarily by small-intestinal Paneth cells, stabilized by three disulfide bonds. It is studied as a core effector of intestinal mucosal innate immunity and as a broad-spectrum antimicrobial research reagent, particularly against Gram-negative bacteria.
