Why doesn't the thymus have follicles?
The thymus does not have follicles because it is primarily involved in the maturation of T-cells rather than the production of antibodies, which is the main function of lymphoid follicles found in lymph nodes and the spleen. Instead of follicles, the thymus has a unique structure composed of epithelial cells, which provide a microenvironment for T-cell development and selection. The absence of follicles reflects the thymus's specialized role in the adaptive immune system, focusing on T-cell differentiation rather than B-cell activation and antibody production.
