What types of cells express Fc receptors that recognize IgG?
Macrophages and neutrophils express Fc receptors that recognize IgG opsonized on microbial surfaces.
What do receptors like FcγRI allow phagocytic cells to do?
Receptors like FcγRI allow phagocytic cells to bind to the Fc portion of an immunoglobulin.
What happens when FcγRI receptors bind to immunoglobulins on pathogen surfaces?
This facilitates phagocytic uptake by macrophages and neutrophils, leading to the removal of the tagged pathogen.
