Function of Macrophages in immune system

Macrophages are specialised phagocytic cells derived from the blood monocytes (one type of white blood cells) which facilitate the destruction of the extracellular antigen and other pathogenic substances by phagocytosis and also act as antigen presenting cell (APC) and processed and present peptide antigen to the naïve T-cell and activate it. Macrophages are mainly two …
