T-suppressor cell
A type of immune cells, also called CD8 cells, these cells close down the immune response after it has destroyed invading organisms. CD8 cells are sensitive to high concentrations of circulating lymphokine hormones and release their own lymphokines after an immune response has achieved its goal, signaling all other participants to cease their attack. Some memory B-cells remain to ward off a repeat attack by the invading organism.

- T-suppressor count
A test that counts the number of T-suppressor (T-8) cells in the bloodstream. It appears that some T-8 cells secrete a substance that can kill the HIV virus, so a high count is believed to be a good indicator for people with HIV (AIDS). See also T- suppressor cells.
- t.i.d. (on prescription)
If a medicine is to be taken every so-many hours, it is written “q_h”; the “q” standing for “quaque” and the “h” indicating the number of hours. So, for example, “2 caps q4h” means “Take 2 capsules every 4 hours.”
- T1-T12 (thoracic vertebrae)
