Reference Entry
A definition of the term "thymus" is presented. It refers to a lymphoid organ that is located in the mediastinal cavity anterior to and above the heart. This organ is composed of two fused lobes each containing multiple lobules. These lobules are roughly divided into an outer cortex and inner medulla. Thymus is the primary site for differentiation of T lymphocyte.

    The article focuses on the identity of thymus-settling progenitors (TSP). It states that TSP has been known as a T-cell development helper. It emphasizes that the main candidate for TSP include the hemopoietic stem cells, as well as its differentiated progeny, common lymphoid progenitors (CLP)...

    Cdc42 of the Rho GTPase family has been implicated in cell actin organization, proliferation, survival, and migration but its physiological role is likely cell-type specific. By a T cell-specific deletion of Cdc42 in mouse, we have recently shown that Cdc42 maintains naïve T cell homeostasis...
