  1. 01LabIn vitro (cells)Activity measurement

    In murine peritoneal and human HMC-1 mast cells, Tbeta4 at 0.2-2000nM induced mediator release of up to 23% in a concentration-dependent manner.

    In plain wordsIn lab tests on mouse and human mast cells, thymosin beta‑4 caused the cells to release mediators, more with higher concentrations.

    Summary
    Exposure to 0.2-2000nM Tbeta4 induced mediator release (up to 23%) in murine peritoneal and human HMC-1 mast cells in a concentration-dependent manner.

    Summary · context
    Mast cells are involved in these processes as well and therefore we investigated the effect of Tbeta4 on mast cells.

Studies that did not test the peptide alone2

In this study, Thymosin beta-4 (human) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Thymosin beta-4 (human).

    The Tbeta4 N-terminal fragment AcSDKP caused low but detectable mediator release in mast cells.

    In plain wordsIn lab tests, a short N-terminal piece of thymosin beta‑4 caused low but detectable mediator release from mast cells.

    Tbeta4 fragments 16-38 and 17-23 stimulated mast cell mediator release at a level equal to or higher than native Tbeta4.

    In plain wordsIn lab tests, two pieces of thymosin beta‑4 made mast cells release mediators as much as or more than the whole peptide.

    Summary
    peptides corresponding to the Tbeta4 amino acid sequences 16-38 and 17-23 stimulated mast cells mediator release on a level equal to or higher than that observed with native Tbeta4.
