What specific function do T-cells serve in the immune response?

T-cells play a crucial role in the immune response, specifically by recognizing and destroying cells that have been infected by pathogens, such as viruses. This action is part of the adaptive immune system, which tailors its response to specific threats.

There are different types of T-cells, including cytotoxic T-cells, which directly kill infected cells, and helper T-cells, which support the immune response by activating other immune cells. When T-cells recognize an infected cell, they bind to the antigens presented on the surface of that cell and can initiate a killing process to eliminate the infection. This is essential for controlling and clearing infections from the body.

In contrast, producing antibodies is a function associated with B-cells, not T-cells. Enhancing red blood cell production is managed by other mechanisms in the body, primarily the hormone erythropoietin. Regulation of body temperature does not involve T-cells and is controlled by different physiological processes. Therefore, the specific function of recognizing and destroying infected cells accurately describes the role of T-cells in the immune response.
