Macrophages express multiple types of receptors on their surface that stimulate phagocytosis of microbes, leading to pathogen internalization and destruction. many of these receptors, such as dectin-1, rely on direct recognition of a pamp on the pathogen surface. however, some receptors that stimulate phagocytosis rely on soluble factors (not associated with the phagocyte membrane) to identify and mark the pathogen for uptake by the phagocyte. one such receptor is: a) the class a scavenger receptorb) the complement receptorc) the mannose receptord) the macrophage c-type lectin receptore) the lipid receptor
