Specific chemokines, such as IP-10, IL-8, MIG/CXCL9 and MCP-1/CCL2 are released from monocytes, alveolar macrophages and polymorphonuclear granulocytes to recruit NK cells, γδ T lymphocytes, and αβ T lymphocytes of CD4+ and CD8+ phenotypes in sequential order into the site of MTb infection [5]-[9]. Here, CXCL8 is linked to infection.
