← Human Body & HealthWhich immunological consequence results when B-cells undergo somatic hypermutation in germinal centers?
A)Increased antibody affinity maturation✓
B)Decreased complement activation cascade
C)Induced immune system self-tolerance
D)Prevented antigen presentation via MHC-II
💡 Explanation
Somatic hypermutation introduces random mutations within antibody genes; affinity maturation occurs because B-cells producing antibodies with higher affinity for the antigen are preferentially selected to survive and proliferate, therefore driving the antibody affinity higher rather than leading to tolerance.
