Skin is a major barrier against the environment and provides the first line of defense against invading microorganisms. Two papers in November 22

They found that cathelicidins are an important native component of innate host defense in mice and provide protection against necrotic skin infection caused by Group A
In another paper, Birgit Schittek and colleagues from Eberhard-Karls-University Tübingen, Germany describe the isolation of the gene Dermcidin, which encodes an antimicrobial peptide having a broad spectrum of activity and no homology to other known antimicrobial peptides.
