Toll-like receptor 10 is a protein that in humans is encoded by the TLR10gene.[3] TLR10 has also been designated as CD290 (cluster of differentiation 290).
TLR10 has not been extensively studied because it is a pseudogene in mice, though all other mammalian species contain an intact copy of the TLR10 gene. Unlike other TLRs, TLR10 does not activate the immune system and has instead been shown to suppress inflammatory signaling on primary human cells.[4] This makes TLR10 unique among the TLR family. TLR10 was thought to be an "orphan" receptor, however, recent studies have identified ligands for TLR10 and these include HIV-gp41.[5] Ligands for TLR2 are potential ligands for TLR10.[6]
