Question

Cell-mediated immune responses are ______.

Options

• enhanced by depletion of complement

• suppressed by cortisone

• enhanced by depletion of T-cells

• suppressed by antihistamine

Answer 1

Cell-mediated immune responses are suppressed by cortisone.

Explanation:

Cell-mediated immune responses are suppressed by cortisone, as it is an immunosuppressive corticosteroid that inhibits T-cell function. Complement depletion or T-cell depletion would reduce or impair cell-mediated immunity, while antihistamines generally do not suppress these responses directly.
