  1. 01LabIn vitro (cells)Activity measurement

    In lymphocytes from head and neck cancer patients and normal subjects, thymosin alpha‑1 further decreased the levels of IL-2 receptor-positive CD4 and CD8 cells at 48 and 72 hours.

    In plain wordsIn lab tests of human lymphocytes, thymosin alpha‑1 lowered the number of cells with IL-2 receptors at 48 and 72 hours.

    Summary
    Thymosin alpha 1 further decreased levels of IL-2 receptor-positive (both CD4 and CD8) cells at 48 and at 72 hours.

    Summary · context
    Recent evidence for the potential importance of in lymphokine interleukin 2 (IL-2) in patients with cancer prompted a study of the kinetics of IL-2 receptor expression on lymphocytes from patients with untreated advanced head and neck cancer and normal subjects and an evaluation of the in vitro effe…
  2. 02LabIn vitro (cells)Mechanism

    In these lymphocytes, the thymosin alpha‑1-induced down-regulation of IL-2 receptors was not due to an effect on proliferation.

    In plain wordsIn lab tests of human lymphocytes, the drop in IL-2 receptors was not explained by a change in cell growth.
