Thymic hormones, in general, inhibit the changes provoked by aging, and helps to maintain the learning and memory capacities in the aging organism. The two – lymphoid and endocrine – parts (function) of the thymus are in close connection directly or with the help of mediators.

The activity of thymic extracts at extra-thymic sites requires further definition. Serum thymic hormone was assayed in genetically-obese (C57B1/6J ob/ob) mice and lean controls (+/+, +/-) of the same strain.

The thymic hormone activity was higher in the majority of the. Polypeptide beta1, in contrast, is inactive in our bioassay systems, suggesting that it is not involved in thymic hormone action. Sequence analysis and homology studies have indicated that polypeptide beta1, although present in Fraction 5, does not contribute to the biological activity of thymosin Fraction 5.

These observations suggest that /31, although present as a major component in thymosin Fraction 5, is not involved in thymic hormone action.
