Integration of antimicrobial host defenses: role of the bactericidal/permeability-increasing protein

Our understanding of the complex and integrated host-defense systems against microbial infection has progressed rapidly with the characterization of individual components. However, the various factors must be studied not only in isolation, but also in a closer approximation to the in vivo situation, where these factors interact. This is well illustrated in recent studies of the role of the bactericidal/permeability-increasing protein.
