  • Termination codon (sequence)

    One of three triplet sequences (U-A-G, U-A-A, or U-G-A) found in DNA molecules (genes) that cause termination of protein synthesis; they are also called nonsense codons. The sequences cause the termination of the peptide chain and its release in free form.  

  • Taxol

    Goined during the 1960s by Monroe E. Wall when it was originally isolated from the Pacific yew tree (genus Taxus) this word is now a trademark of the Bristol-Myers Squibb Go. Taxol now refers to the anticancer preparation sold by Bristol-Myers Squibb Gompany. The active compound from Pacific yew tree is now known as paclitaxel.…

  • TATA homology

    An adenine-thymidine-rich (gene) sequence present 20 to 30 nucleotides “upstream” of the transcription start site on most eucaryotic protein coding genes; it is required for correct expression. Recent research indicates that blocking this portion of the (gene) sequence may inhibit ability of the AIDS virus to reproduce.  

  • Target

    The molecule (e.g., receptor) or moiety that a given drug or therapeutic regimen (e.g., gene delivery) is “aimed” at. Any component of the human body that can be affected by a drug. A place which is to be hit by something. Within an X-ray tube, the target refers to the anode, which serves as the…

  • Tachykinins

    A class of neuropeptides (i.e., peptides produced by cells of the nervous system; neurons) which includes neurokinin A, neurokinin B, eledoisin, physalaemin, kassinin, substance P, and substance K. Some of these neuropeptides (e.g.. Substance P) are picked up by mast cells, lymphocytes, and/or monocytes; and cause those three types of immune system cells to release…

  • T cell receptors

    Antibody-like transmembrane (i.e., across the cell’s surface membrane) proteins located on the surface of T cells. These trigger the (cellular) immune response that is mounted by T cells when these receptors bind to antigens (foreign pieces of antigenic protein) which have been “presented” to these receptors by an MHC protein which itself is located on…

  • T cell modulating peptide (TCMP)

    A short protein chain that is thought to restrain certain types of T cells from attacking an (arthritis) afflicted patient’s tissues (mainly cartilage). Arthritis is caused by the arthritis sufferer’s own immune system attacking the body’s cartilage tissues.  

  • Trayat

    Liberation, a root word from which tantra originates.  

  • Tapas

    Heat used for purification. In Spain, glasses of wine are often served with hors d’oeuvres known as tapas, sometimes offered in such abundance that they take the place of a meal. Originally, these small snacks were simply slices of bread, garnished with some savoury item and placed on the top of the wine glass by…

  • Tantra

    An approach to yoga which embraces all experience as divine and inherently capable of expanding one’s awareness into a state of liberation, free from the limitations of the mind and body. A spiritual path for deifying the body, utilising all the senses. Successfully practised, this results in being carried across to the other side of…
