... aged thymocytes is a reflection of the generalized increased output of antibodies by B cells in the aged thymus. Given that the actual number of circulating B cells within the thymus is very small, ... One of the underlying causes of the reduced effectiveness of the immune system with age is the involution of the thymus. As the thymus involutes, the...
