Outline of Final Research Achievements |
Phosphatidyl-inositol mannosides (PIM) are unique mycobacterial glycolipids that stimulate host immune responses. Mycobacteria activated reporter cells expressing DCAR and delipidation of mycobacteria abolished this activity. Further, tri- and tetra-acylated PIMs (AcPIM2 and Ac2PIM2) purified from mycobacteria lipids were ligands for DCAR. DCAR was predominantly expressed in small peritoneal macrophages (SPMs) and monocyte-derived inflammatory cells in lungs and spleen. PIM treatment induced these cells to produce MCP-1, and production of MCP-1 was abrogated in the absence of DCAR or FcRγ. Upon mycobacterial infection, DCAR-deficient mice showed reduced numbers of monocyte-derived inflammatory cells at the infection site, impaired IFNγ production by CD4+ T cells, and an increased bacterial load. These results demonstrate that DCAR is a critical receptor for mycobacterial PIM and functions to promote Th1 responses against mycobacteria.
