Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them are called T4 cells. They are also known as T helper cells.
the B-cells.
Do you mean lymphocytes? Lymphocytes are white blood cells which make chemicals called antibodies. Antibodies destroy bacteria which get into the blood. They give us immunity to diseases.
Antibodies
Both are T and B lymphocytes are produced in bone marrow, but B lymphocytes mature in bone marrow and are part of the humoral response, while T lymphocytes mature in the thymus gland and are part of the cell mediated response.
The antigen itself cannot destroy the pathogen but here are three ways it helps out:1. Antibodies can clump antigens together in order to enhance phagocytosis2. Antibodies can activate the cytotoxic cell responses (a chemical that destroys antibody-bound antigen).3. Antibodies can activate B lymphocytes, which results in the production on plasma and memory cells.
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
Antibodies attach to antigens preventing them from attacking cells in the body. Antitoxins attack antigens and destroy them
complement fixation
Lymph nodes are located along lymphatic pathways, and contain lymphocytes and macrophages, which destroy invading microorganisms. They remove and destroy potentially harmful foreign particles from the lymph through phagocytosis by macrophages. They are also the centers for the production of lymphocytes that act against foreign particles.Lymph nodes are located along lymphatic pathways, and contain lymphocytes and macrophages, which destroy invading microorganisms.
