If a new viral strain exploits dendritic cell surface receptors to inhibit MHC-II complex presentation to T-helper cells, which consequence follows?

💡 Explanation

Suppression of MHC-II presentation impairs T-helper cell activation, because these cells require MHC-II complexes displaying antigens to initiate adaptive immune responses. Therefore, adaptive immunity is suppressed, rather than overstimulated antibody production or cytotoxic T-cell proliferation without T-helper cell coordination.
