What are T cells?

Type of lymphocyte. When lymphocytes were first recognized as a small population of the white blood cells, Bob Good divided them into T and B cells. The T cells were matured in the Thymus and the B cells in the Bursa of Fabricius found in the chicken. The B cells produce antibody andthe T cells contain cells ie. Th 1, making IL2 and the Th2 IL 10. The TH 1 targets bacteria and viruses.

What is adoptive t-cell therapy?

Delivery of T cells. Adoptive T cell therapy is a form of immunotherapy for malignancy that involves isolation and ex vivo expansion of tumor specific T cells to deliver a greater number of T cells to the tumor than by vaccination alone. These tumor specific T cells are infused into patients with cancer in an attempt to give their immune system the ability to overwhelm remaining tumor.. Tumor infiltrating lymphocytes or TIL have been used by isolating and expanding one particular T cell or clone have been engineered to potently recognize and attack tumors with minimal effect. It is now being recognized that IgG1’s can be more effective than TIL thru ADCC. Read more...

None for sure. Living a healthy life is one way to help preserve your immune system. There are indeed medications which can boost your t cell function but the side effects are also not insignificant-at least for now. I know of no proven supplements which will increase T cell production. Read more...

What number of t-cells does HIV infect?

Replication. The number of cells infected depends on the number of available cells wh/express a cd4+ receptor (helper lymphocytes, dendritic cells, and other cells with the receptor) and how much fit virus is floating around to take up the viral particles. If the virus has a high replicative capacity and the virions are fit (no mutations), many cells will be infected/. If no than the number infected is low. Read more...
