Research progress on Toll-like receptor 2(TLR2)with Mycobacterium tuberculosis infection
Toll-like receptor 2(TLR2)is a pattern recognition receptor expressed on the surface of leukocytes.Various ligands can activate or inhibit TLR2,therefore regulating the inflammation and apoptosis of immune cells.Mycobacterium tuberculosis(MTB)typically parasitizes macrophages.Further,after infecting the body,MTB can interact with TLR2 on the surface of various immune cells,including macrophages,leading to the release of cytokines that can affect the state and proliferation of MTB in the body.Additional research is needed to understand the polymorphism of TLR2 at the molecular level.Current studies indicate that the majority of TLR2 polymorphisms are not associated with susceptibility to MTB infection.This review provides an overview of the researches related to TLR2 and its ligands,the immune regulation activities of TLR2 following MTB infection,and the association of TLR2 polymorphism with susceptibility to MTB.
