Final answer:
The answer is False. T cells are made in the bone marrow and can trigger other immune cells to produce antibodies.
Step-by-step explanation:
T cells are a type of white blood cell that play a critical role in the immune response. They are made in the bone marrow and mature in the thymus gland. T cells can be activated by the presentation of foreign antigens on MHC molecules. Once activated, they can trigger other immune cells, such as B cells, to produce antibodies.
Option A is true. T cells can release cytokines, which are signaling molecules that help regulate the immune response.
Therefore, the answer is False. T cells are made by the bone marrow, not by other T cells.
