Function
APA_MYCTU A potent antigen in animals immunized with live bacteria, it induces a strong delayed-type hypersensitivity (DTH) in immunized animals (PubMed:10531201). Elicits a mostly Th1 type of T-cell response in healthy humans; induces IFN-gamma production from CD4(+) and CD8(+) cells (PubMed:12654810). Functions as an adhesin, binds to mouse macrophages via mannose residues (PubMed:10531201, PubMed:25359607). Might interact via host CD209 (PubMed:16092920).[1] [2] [3] [4]
