HKMT

HKMT is a heat-killed preparation of the avirulent strain of Mycobacterium tuberculosis H37 Ra.

HKMT is sensed by Mincle which recognizes the mycobacterial cell wall glycolipid TDM. HKMT also possesses a large repertoire of TLR2 ligands, such as lipoproteins and lipomannan. Upon HKMT sensing, both Mincle and TLR2 lead to the activation of NF-κB.
