Cell-mediated immunity involves:

A) T lymphocytes.

Cell-Mediated Immunity

An immune response that does not involve antibodies but rather the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

T Lymphocytes

A type of white blood cell crucial for the immune system's response to infected or cancerous cells.

Antibodies

Proteins produced by the immune system that recognize and bind to specific antigens, such as bacteria or viruses, to neutralize or destroy them.
