Plain Language Summary

This study demonstrated that thymosin alpha-1 has beneficial effects on lipid metabolism in hypercholesterolemic rabbits. After thymosin alpha-1 injection, erythrocyte lipid levels decreased significantly while erythrocyte membrane Na+/K+-ATPase activity increased. These findings suggest thymosin alpha-1 influences both lipid homeostasis and membrane enzyme function, expanding its known biological activities beyond immune modulation.

Abstract

Thymosin alpha-1 is an active polypeptide isolated from thymus. This polypeptide is widely used in the diagnosis and treatment of many diseases, especially immune diseases. In this present study, we examined the effects of thymosin alpha-1 on plasma and erythrocyte lipid levels and the changes in erythrocyte membrane (Na+, K+)ATPase activity in hypercholesterolemic rabbits. The erythrocyte lipid levels decreased, whereas the erythrocyte membrane (Na+, K+)ATPase activity increased significantly in these rabbits after thymosin alpha-1 injection. These findings suggest that thymosin alpha-1 is effective on both the lipid level and erythrocyte membrane (Na+, K+)ATPase activity.
