What is the role of thymosins in the immune system?
Options
- ARegulation of blood pressure
- BSecretion of insulin
- CDifferentiation of T-lymphocytes and production of antibodies
- DMaintenance of water and electrolyte balance
Correct answer
C. Differentiation of T-lymphocytes and production of antibodies
Step-by-step solution
The thymus gland is a lobular structure located between lungs behind sternum on the ventral side of aorta. The thymus plays a major role in the development of the immune system. This gland secretes the peptide hormones called thymosins. Thymosins play a major role in the differentiation of T-lymphocytes, which provide cell-mediated immunity. In addition, thymosins also promote production of antibodies to provide humoral immunity. Thymus is degenerated in old individuals resulting in a decreased production of thymos
