What is T-cell immunity?

Immunity

T-cells is a reaction in the body's immune system by which the immune system recognizes a foreign attacker called antigen, and responds by destruction. There are two types of white blood cells: B-cells and T-cells. T-cell immunity is used to destroy white blood cell antigens or lymphocytes called T-cells or T-lymphocytes. This particular immune response is different from other immune responses, such as a compliment system's protein reaction or the use of body phagocytes to eat foreign bodies, although these elements are involved in T-cell immunity.

There are several types of T-cells in the body: auxiliary T-cells, killer T-cells, suppression T-cells and memory T-cells. Although T-cells, like other lymphocytes, are formed in the bone marrow in the body, T-cells move into the thymus after development. This function also gives it its name "T-Cell".

Immunity T-cell is to evoke other components of the immune system, starting with PRoces called antigen presentation. First Fagocyte, such as a macrophage, captures and absorbs the attacker. He then travels to the lymph node to give information about the attacker to the auxiliary T-cell by representing pieces of antigen on its surface. The receptors of each auxiliary T-cell recognize only one type of antigen, so Fagocyte must find the right assistant T-cell to recognize it and cause a reaction. When the T-cell finally recognizes the antigen, it starts to divide and create proteins called cytokines to announce the rest of the immune system-zabel T-cells and B-cells-to continue the immune response.

The

T-cells are also known as cytotoxic T-lymphocytes. As their name suggests, the attack and killing of infected cells react, which would not notice other components of the immune system. Its receptors check every nearby cell, thus attacking any cell that shows the signs infection using an enzyme that eventually kills the cell in question. Types of infections that can affectThus, the cell-and the reaction of the T-Bulberry-Bulk-zero-bare viruses, bacteria and even cancer.

As soon as the antigen is detained, other T-cells stem into action. For example, suppression T-cells try to reduce other killer T-cells from unnecessary formation. In addition, the T-cell memory remember that a specific antigen that provokes a faster reaction if the attacker ever returns to the body.

Immunity

T-cells is also known as immunity mediated by cell and can itself be disturbed by viruses as human immunodeficiency virus (HIV). Specifically, these types of viruses focus and kill auxiliary T-cells to seriously weaken the basic immune response. For example, this HIV action is what causes the body to eventually succumb to the obtained immune deficiency syndrome (AIDS).
