Detailed explanation-1: -Your thymus actually starts making T-cells before you’re born. It keeps producing T-cells and you have all the T-cells you need by the time you reach puberty. After puberty, your thymus gland slowly starts to decrease in size and is replaced by fat.
Detailed explanation-2: -Viral, bacterial, and fungal infections are common causes of acute thymic atrophy. Of particular concern is the human immunodeficiency virus (HIV), which can cause an infection that severely alters the normal function of the thymus as a result of the loss of developing thymocytes and thymic stromal cells.
