CAMP and susceptibility to pneumonia measurement: Recently, Hou et al.31reported that the antimicrobial peptide LL-37 and innate defense regulator peptide IDR-1 could ameliorate MRSA-induced pneumonia by exerting an anti-inflammatory property and attenuating pro-inflammatory cytokine release, thereby providing support for the hypothesis that both innate and synthetic peptides could play a role of protection against MRSA in vivo.
