Question

multiple choice question
which t cell inhibits multiplication and cytokine secretion by other t cells and thus limits immune responses?

• cytotoxic t cell
• memory t cell
• helper t cell
• regulatory t cell

Explanation:

To solve this, we analyze each T - cell type:

• Cytotoxic T cells kill infected or abnormal cells, not inhibit other T cells' multiplication/cytokine secretion.
• Memory T cells are for long - term immunity and rapid response on re - exposure, not for limiting immune responses.
• Helper T cells activate other immune cells, promoting immune responses.
• Regulatory T cells (Tregs) have the function of suppressing the activity of other T cells, including inhibiting their multiplication and cytokine secretion to regulate and limit immune responses.

Answer:

D. Regulatory T cell
