A, DCs with stimulatory phenotype, high expression of MHCII, CD40, CD86, CD80, and secreting IL-12, are likely to support a Th1-IFNγ producing T cell phenotype. This DC phenotype will result in mycobacterial killing within macrophage through the secretion of IFNγ by T cells. B, DCs found within chronic granulomas with low expression of T cell stimulatory molecules and secreting IL-10, will be liable to support an anergic or regulatory T cell response. This would result in less local IFNγ production, and thus, maintain mycobacterial latency inside macrophage.
