The thymic cortex has a substantial population of macrophages in addition to the developing T cells (i.e., thymocytes). These macrophages are extremely useful in:
A) Eliminating bacterial infections in the thymus
B) Producing cytokines that promote T cell maturation
C) Engulfing apoptotic thymocytes
D) Maintaining the structural integrity of the thymic organ
E) Inducing inflammatory signals to increase blood flow to the thymus

Question

Quizplus · Accepted Answer

Macrophages in the thymic cortex play a critical role in engulfing and removing apoptotic thymocytes, which are a natural by-product of T cell development. This process helps prevent the release of potentially harmful cellular debris and antigens, which could trigger an immune response or autoimmunity.
