T cellWith the B cell, one of the two main types of white blood cell, essential parts of the immune system. T cells originate in the bone marrow, mature in the thymus, and travel in the blood to other lymphoid tissues, such as the spleen, tonsils, and lymph nodes. Through receptor molecules on their surfaces, T cells directly attack invaders (antigens) by binding to them and helping remove them from the body. Because the body contains millions of T and B cells, many of which carry unique receptors, it can respond to virtually any antigen. See also antibody, immunology. T cell [′tē ‚sel] (immunology) One of a heterogeneous population of thymus-derived lymphocytes which participates in the immune responses. Also known as T lymphocyte.

OTCBB:PFTR), a company involved in the development and commercialization of cell therapies, announced today that the Company will present three poster presentations based on their adult human T-cell vaccination and stem cell regenerative medicine platform technologies at the 2006 Annual Meeting of the International Society for Cellular Therapy (ISCT) in Berlin at the proArte Hotel on May 5, 2006. It was demonstrated that this extract, which contains a complex mixture of regulatory agents, but no genetic material, conferred the T-cell functional program on the skin cells. There are also a number of Isolex(R) systems currently in use in investigational protocols for gene therapy and dendritic cell therapy, engineered transplants with alternative donors and for autoimmune diseases, and depletion of specific T-cell subsets such as CD4 or CD8 cells. |
