  • Title: Antimicrobial peptides in the brain.
    Author: Su Y, Zhang K, Schluesener HJ.
    Journal: Arch Immunol Ther Exp (Warsz); 2010 Oct; 58(5):365-77. PubMed ID: 20668978.
    Abstract:
    Antimicrobial peptides (AMPs) are an evolutionarily conserved component of the innate immune system of many species. The brain is an immunologically privileged organ but can produce a robust immune response against pathogens and cell debris, promoting rapid and efficient clearance. AMPs may be critically involved in the innate immune system of the brain. Though the mechanisms of AMPs' action in the brain still need further elucidation, many studies have shown that AMPs are multifunctional molecules in the brain. In addition to antimicrobial action, they take part in congenital and adaptive immune reactions (immunoregulation), function as signaling molecules in tissue repair, inflammation and other important processes through different mechanisms, and they might, in addition, become diagnostic markers of brain disease.
