Question

question 20 1 pts the presentation of an antigen by an antigen - presenting cell activates the t cell. the cell then divides repeatedly to form a clone of identical sensitized t cells that form effector t cells and cytokines. effector t cells and memory cells. memory cells and cytokines. memory cells and interleukins.

Explanation:

When a T - cell is activated by an antigen - presenting cell, it undergoes clonal expansion. The resulting clone of sensitized T - cells differentiates into two main types: effector T - cells (which carry out the immediate immune response, such as killing infected cells) and memory T - cells (which remain in the body to provide a faster and more robust response upon re - exposure to the same antigen). Cytokines are signaling molecules, but they are not a type of T - cell. Interleukins are a subset of cytokines.

Answer:

effector T cells and memory cells.
