  1. 01AnimalAnimal study (in vivo)Efficacy outcome

    In mice with cyclophosphamide-induced immunodeficiency, repeated thymosin alpha‑1 injection accelerated restoration of the reduced number of CD4+CD8+ thymocytes.

    In plain wordsIn mice with a weakened immune system, thymosin alpha‑1 helped restore the number of thymus T cells faster.

    Outcome
    IncreaseCD4+CD8+ T cell number in thymus

    Summary
    Repeated injection of 30-300 microg/kg/day of Talpha1 after CY-treatment significantly accelerated the restoration of the reduced number of CD4+CD8+ T cells in the thymus.

    Summary · context
    Here, we characterized immunostimulating properties of Talpha1 in experimental immunodeficiency of mice that was induced by the administration of cyclophosphamide (CY).
