Toll-like receptors.
Ref: – British Journal of Dermatology 2005 153, pp1105-1113
Today I read one interesting article titled “Induction of toll-like receptors by propionibacterium acnes”. Toll-like receptors (TLRs) are recently identified group of receptors with homologues in Drosiphila, important in immediate immunological response. 10 different types of TLRs have been identified which are trans-membrane proteins with a leucine-rich extracellular domain and a cytoplasmic domain, called the TIR domain, analogous to the fruit fly Toll protein. They bind to various bacterial antigens like peptidoglycans, Lipoarabinomannans or lipo polysaccharides. Inflammation in acne is due to induction of TLR-2 and TLR-4.
Is there any similarity with MHCs?
Any role in lepra reactions?
Interested in exploring further?
