Results from this study3

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

Natural levels measured3

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In juvenile squirrel monkeys, circulating thymosin alpha‑1 fell significantly after social separation, together with increased adrenocortical activity.

    Summary
    Thymosin alpha 1 was significantly decreased after social separation in association with increased adrenocortical activity, especially during the first day after being housed alone.

    Summary · context
    Thymosin-alpha 1 (thymosin alpha 1) and cortisol levels were evaluated in juvenile squirrel monkeys to investigate the influence of psychological disturbance on thymic and adrenal hormone activity.

    This result measures the body's own Thymosin alpha-1. Nobody was given the peptide. It is not evidence about taking it.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Other

    In a second study in squirrel monkeys, the fall in thymosin alpha‑1 levels was replicated and depended on psychosocial factors that changed the level of disturbance.

    In plain wordsIn squirrel monkeys, a second study again showed a fall in the body's own thymosin alpha‑1, linked to stress level.

    Summary
    A second study verified that the decrement in thymosin alpha 1 levels was replicable and also sensitive to psychosocial factors that influence the level of induced disturbance.

  3. 03AnimalEndogenous levelAnimal study (in vivo)Other

    In squirrel monkeys, pharmacological inhibition of the cortisol response and of opiate hormone action partly attenuated the change in thymosin alpha‑1 secretion.

    In plain wordsIn squirrel monkeys, blocking cortisol or opiate action partly reduced the change in the body's own thymosin alpha‑1.

    Summary
    In addition, changes in thymosin secretion could be attenuated partially by pharmacological inhibition of the cortisol response and opiate hormone action.
