Macrophages Express Multiple Types of Receptors on Their Surface That

Multiple Choice

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 mannose receptor
B) The class A scavenger receptor
C) The lipid receptor
D) The macrophage C-type lectin receptor
E) The complement receptor
