It wasn’t until the early 1960s that Australian immunologist Jacques Miller made an amazing discovery: The thymus is the place where T cells, the major effector cells of the immune system, are generated. This image of a mouse thymus shows all cells in the thymus (blue); the red portion indicates the thymus medulla.
Within the thymus, T cells mature. T cells are critical to the adaptive immune system, where the body adapts specifically to foreign invaders. The thymus is composed of two identical lobes and is located anatomically in the anterior superior mediastinum, in front of the heart and behind the sternum.
Within the thymus, thymus cell lymphocytes or T cells mature. T cells are critical to the adaptive immune system, where the body adapts specifically to foreign invaders.
