Toll-like receptor 2 (IPR027185)

Short name: TLR2

Family relationships

Description

Toll-like receptor 2 (TLR2) is a member of the Toll-like receptor (TLR) family, which plays a role in activation of innate immunity and pathogen recognition [PMID: 11680785]. It helps mediate the innate immune response to bacterial lipoproteins and other microbial cell wall components, acting via MyD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response [PMID: 12610729, PMID: 17449723, PMID: 10426995, PMID: 12594207]. TLR2 in association with TLR1 or TLR6 is essential for recognising bacterial lipoproteins and lipopeptides [PMID: 11431423, PMID: 12077222]. It also promotes apoptosis in response to lipoproteins [PMID: 10426996].

Genetic variations in TLR2 are associated with susceptibility to leprosy, a chronic disease associated with depressed cellular (but not humoral) immunity [PMID: 18177245, PMID: 12646604].
