You asked! T cells belong to a group of white blood cess known as lymphocytes and play a central role in cell-mediated immunity. They can be distinguised from other lymphocyte types, such as B cells and NK cells by the presence of a special receptor on their cell surface that is called the T cell receptor (TCR). The 'T' in T cell stands for thymus since it is the principal organ, found dircetly behind the top of the sternum, for their development. Links to the virus that causes AIDS, HTLV-III. Human T-lymphotropic virus, type III.
B cells stand for Bursa of Fabricus and T cells stand for T-lyphocytes.
t cells are killer cells b cells are antibodies
Regulatory T-cells
Helper T cells activate killer T cells.
Yes, cytotoxic T-cells are a subset of T-cells that in contrast to helpter T-cells express CD8.
T cells apex or B cells
Killer t cells are activated by helper t cells. The Helper t cells are alerted by the macrophage that has engulfed the virus. It grows antigens to alert the helper t cells. The killer t cells are like white blood cells, there purpose is to fight pathogens.
The T in T-cells stands for the thymus gland. Lymphocytes produced in the bone marrow are either become B-cells or they are matured in the thymus gland and are "trained" to be either Natural Killer T-cells, CD4 (Helper T-cells), CD8 (Suppressor T-cells).
this is my question what is the function of t-cells?
T cells destroy pathogens.
B-cells and T-cells are both produced in the bone marrow. B-cells stay in the bone marrow but T-cells migrate to the thymus
Cytotoxic T-cells are just a specialized subset of T-cells that express CD8 (a co-stimulatory molecule). In general, there are two types of T-cells, helper T-cells that express CD4 and cytotoxic T-cells that express CD8. As the name implies, cytotoxic T-cells have the role of killing any infected cells.
