← Human Body & HealthWhich outcome occurs when B-cell receptors become insensitive?
A)Impaired antibody-mediated immune response✓
B)Enhanced interferon production
C)Increased histamine synthesis
D)Reduced erythrocyte production
💡 Explanation
Reduced B-cell receptor sensitivity diminishes B-cell activation which depends on crosslinking surface-bound immunoglobulin; this causes impaired antibody-mediated immune response. Therefore immune protection is lowered rather than allergy or red blood cell production because receptor mechanisms are compromised, not specific blood components.
