Human TLR10 is an anti-inflammatory pattern-recognition receptor
Abstract
We demonstrate the biological role of TLR10, the only member of the Toll-like receptor (TLR)-family so far without a known function. We show that TLR10 acts as an inhibitory receptor, with suppressive effects. Blocking TLR10 by specific antibodies significantly upregulated TLR2-mediated cytokine production. Additionally, we show that individuals carrying loss-of-function SNPs in TLR10 display upregulation of TLR2-mediated cytokine production. After challenging human TLR10 transgenic mice with TLR2 ligand pam3CSK4 (Pam3Cys), less inflammation could be observed when compared with wild-type mice. Taking these data together, we show that TLR10 is the only pattern-recognition receptor within the TLR family that is able to dampen TLR2 responses, thereby suppressing immune responses through production of IL-1Ra.
