Cell-mediated immunity, also known as cellular immunity, is one of the two types of the adoptive immune system inside the body. It is mostly responsible for fighting microbes and antigens or foreign substances inside the cells. The T lymphocytes, or thymus-derived lymphocytes, are a key part of cell-mediated immunity.
After activation by T H cells, B cells release proteins called antibodies. Antibodies travel through the body's fluids and attach to antigens, targeting them for destruction by nonspecific defenses. This type of immune response is called antibody-mediated immunity (or humoral immunity).
