All T-cells originate in the same place in humans. They originate from hematopoietic stem cells which are located in the bone marrow.
No. Both B- and T-cell precursors come from the bone marrow. B-cells hang around in bone marrow to mature (hence the "B"). T-cells develop in the thymus (hence the "T").
B cells stand for Bursa of Fabricus and T cells stand for T-lyphocytes.
t cells are killer cells b cells are antibodies
Helper T cells activate killer T cells.
Regulatory 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).
T cells destroy pathogens.
this is my question what is the function of t-cells?
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
