← Life Sciences & MedicineIf a pathogen enters the body, which consequence follows from opsonization by IgG antibodies?
A)Inhibition of T cell activation
B)Enhanced phagocytosis by macrophages✓
C)Reduced complement cascade initiation
D)Decreased antigen presentation by dendritic cells
💡 Explanation
Opsonization coats pathogens with IgG, because this process flags them for destruction by phagocytes. This enhances phagocytosis by macrophages and neutrophils, therefore the pathogen is more efficiently cleared rather than inhibiting T cells or reducing complement.
