Final answer:
T cells differentiate and acquire the capacity to produce (3) cytokines, which are crucial for managing immune responses and are part of cell-mediated immunity. Immunoglobulins are produced by B cells, not T cells, and are involved in the humoral immune response.
Step-by-step explanation:
As T cells divide and differentiate, they acquire the capacity to produce cytokines. These are soluble factors that T cells secrete to communicate with other cells of the immune system, thus managing the immune responses. This process is a key part of cell-mediated immunity, where T cells can become either killer T cells or helper T cells. Killer T cells are responsible for destroying cells that are infected with pathogens or are cancerous, whereas helper T cells release cytokines to control and coordinate the actions of other leukocytes.
The production of immunoglobulins, also known as antibodies, is associated with B cells, not T cells. Immunoglobulins bind to specific antigens on pathogens or infected cells, leading to their destruction. The humoral immune response includes this. Despite not producing immunoglobulins, T cells are essential for the adaptive immune response because they create cytokines and regulate cellular connections.
