T cell undergoes maturation in the thymus and one of the tests it must pass to mature into a single positive mature naive T cell is positive selection. In positive selection your body is making sure that the T cell that it produces is reactive to your own MHC. If it cannot bind to your own MHC, the T cell is useless and it will just die by neglect in your thymus. In positive selection the T cell is "tickled" with thymic endothelial cells that express your own MHC class 1 and MHC class 2. If there is an affinity of the T cell to bind to your MHCs it will continue to the next step in maturation which is negative selection. If the T cell binds way too strongly to your MHC it will also die. There is a specific range that it must bind to your own MHC for it to continue.
The thymus goes through a positive and negative selection for T cells. T cells will respond to MHC class 1, either ignore if self or activate to destroy if foreign.
T cells mature in the thymus The T-cells mature in both the thymus gland and the organs known as tonsils.
Lymphocytes... more specifically T lymphocytes.
Yes
The white blood cell that is formed in the thymus and attacks cancer cells is called a "T lymphocyte" or "T cell." T lymphocytes are a type of immune cell that plays a crucial role in the body's immune response against cancer and various other pathogens. They are part of the adaptive immune system, which recognizes and targets specific antigens, including cancer cells. T cells undergo maturation in the thymus, which is a specialized organ located behind the breastbone. During their maturation process, T cells develop the ability to recognize foreign antigens presented by other cells in the body, including cancer cells. Once mature, T cells can circulate throughout the body to identify and eliminate cells that display abnormal or cancer-associated antigens.
T lymphocytes undergo their final maturation in the thymus, hence why they are called 'T cells'.
The thymus goes through a positive and negative selection for T cells. T cells will respond to MHC class 1, either ignore if self or activate to destroy if foreign.

Im afraid that your question is quite unclear. If you are refering to how the thymus turns pre-T Cells into Naieve T-cells, this is not a process mediated by a secretion. Its a process called positive and negative selection (or central tollerance) mediated by surface molecules called MHCs present on thymic cells and Dendritic Cells, which eliminates those cells that either do not react with these MHCs or react too strongly. I hope this answers your question.............
False, the Thymus lacks B cells.
No. Your thymus is lymphoid organ. It does not produce the red blood cells.
The thymus gland, it promotes the maturation of T-cells.
Stem cells seed which structure that helps develop T cells are the thymus gland.
The primary function of the thymus is the processing and maturation of special lymphocytes (white blood cells) called T-lymphocytes or T-cells, which are associated with antibody production. T-lymphocytes migrate from the bone marrow to the thymus, where they mature and differentiate until activated. in short the thymocytes present in the thymus produces the T lymphocytes
Body cells do not undergo meiosis. Reproductive cells undergo meiosis, body cells, mitosis.
killer t cells
Yes, T lymphocytes mature in the Thymus Gland.
