Abstract:
As an obligate intracellular pathogen, the principal host cells for Mycobacterium leprae are mononuclear phagocytes or macrophages. The macrophage is a primitive cell type being found in both early and advanced life forms, and possesses a variety of functions, such as phagocytosis of invaded bacteria, production of cytokines, antigen presentation and tumor killing. Hansen's disease is a chronic infectious disease characterized by specific host immune responses against M. leprae. In this article the macrophage is focused to dissect its functions in the disease.
Insights
Mycobacterium leprae infects macrophages, key immune cells. This article explores macrophage functions in Hansen's disease, detailing their role in the host immune response to this infection.
