Bactericidal/permeability increasing protein and host defense against gram-negative bacteria and endotoxin

Curr Opin Immunol. 1993 Feb;5(1):103-7. doi: 10.1016/0952-7915(93)90088-a.

Abstract

The bactericidal/permeability increasing protein is a major element in the host defense against Gram-negative bacteria and endotoxin, acting intracellularly in the polymorphonuclear leukocyte. As an isolated protein, bactericidal/permeability increasing protein also acts as an extracellular bactericidal and endotoxin-neutralizing agent and, when injected, protects animals against lethal effects of Gram-negative bacteria and endotoxin.
