  1. 01AnimalAnimal study (in vivo)Efficacy outcome

    In normal and immunosuppressed mice, orally administered Talpha1 significantly increased CD8+ levels.

    In plain wordsIn mice, thymosin alpha‑1 given by mouth raised CD8+ immune cells, in normal mice and in mice with a weakened immune system.

    Outcome
    IncreaseCD8+ level in normal and immunosuppressed mice

    Summary · context
    Dried yeast containing three different concentration of Talpha1 was fed to normal Balb/c mice and other Balb/c mice whose immunities were inhibited in advance by cyclophosphamide.
  2. 02AnimalAnimal study (in vivo)Efficacy outcome

    In immunosuppressed mice, CD8+ levels in the synthesized Talpha1 group were significantly higher than in the empty yeast group.

    In plain wordsIn mice with a weakened immune system, synthetic thymosin alpha‑1 raised CD8+ cells more than empty yeast.

    Summary
    Especially in immune inhibition Balb/c mice, CD8(+) levels in synthesized Talpha1 group (18.77%+/-4.72%), small dose group (13.48%+/-6.17%) and large dose group (22.74%+/-1.09%) were significantly higher than that in empty yeast control group (7.49%+/-2.14%).
