Results from this study2

No result from this study comes from a test of the peptide.

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).

  1. 01LabNot a test of Thymosin beta-4 (human) aloneEx vivo tissueActivity measurement

    In T-lymphocytes from uremic patients incubated in human serum, the thymosin beta‑4 analog with D-Ala in place of the acetyl group restored the impaired blastogenic response.

    In plain wordsIn lab tests on uremic blood cells, an altered thymosin beta‑4 analog (D-Ala) restored a weakened immune cell response.

    Summary
    One of the synthetic analogs, D-Ala-thymosin beta 4 demonstrated a restorative effect on these patients when incubated in human serum

    Summary · context
    Two analogs of thymosin beta 4 the N-terminal acetyl groups of which were substituted by Ala or D-Ala, were synthesized by the solution method and studied for their immunological effect on the impaired blastogenic response of T-lymphocytes isolated from uremic patients after treatment of human serum.

    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. This result is not evidence about taking Thymosin beta-4 (human).
