Neutrophils can proliferate at inflammatory sites, but macrophages are terminally differentiated and do not have the ability to proliferate

Neutrophils express the high-affinity FcγRI receptor, which binds a specific opsonin attached to microbes and aids in phagocytosis, unlike macrophages

Neutrophils can survive for several days at sites of inflammation, whereas macrophages have a much shorter lifespan, lasting only hours

Both neutrophils and macrophages do not express MHC I

Both neutrophils and macrophages are capable of phagocytosis and can eliminate internalized microbes
