Detailed explanation-1: -In the thymus, T cells develop their specific T cell markers, including TCR, CD3, CD4 or CD8, and CD2. T cells also undergo thymic education through positive and negative selection. The thymus is a multi-lobed organ composed of cortical and medullary areas surrounded by a capsule.
Detailed explanation-2: -The thymus makes white blood cells called T lymphocytes. These are also called T cells. These are an important part of the body’s immune system, which helps to fight infection. The thymus gland grows to its largest size during childhood and makes all the T cells we need before we become teenagers.
Detailed explanation-3: -T cells and B cells derive their names from the organs in which they develop. T cells develop in the thymus, and B cells, in mammals, develop in the bone marrow in adults or the liver in fetuses.
