← Human Body & HealthIf a novel virus induces widespread apoptosis of dendritic cells, which consequence follows for adaptive immunity?
A)Increased antibody class switching
B)Impaired T-cell activation occurs✓
C)Enhanced complement-mediated lysis
D)Elevated innate interferon production
💡 Explanation
Impaired T-cell activation follows dendritic cell apoptosis because dendritic cells are antigen-presenting cells, and their reduced presence hinders T-cell priming via the MHC molecules. Therefore, T-cell activation is impaired, rather than enhanced innate immunity or antibody class switching, which rely on different initial signals.
