It is now well established that it is one of the primary central lymphoid organs, the other being the red bone marrow, from which it receives T-lymphocyte precursors. The thymus gland, while providing thymus-processed T-lymphocytes to the entire body, also produces some special humoral ...
The thymus is an important organ of the immune system (see Chap. 3). Numerous experimental and clinicopathologic investigations have demonstrated that the immunologic function of the thymus is closely dependent on the presence of normal thymic structures....
It functions as the initial site of T cell immune maturation through positive and negative selection processes. T cells gain their name as they mature in the thymus and B cells are so named, as they mature in the bone marrow. This article will describe the anatomy, histology and function ...

Additionally, the SNS regulates immunity through the innervation of immune organs such as the spleen, thymus, and lymph nodes.[15][22]This influence may up- or down-regulate inflammation.[23]Cells of the adaptive immune system primarily express beta-2 receptors, while those of the innate immune...

In the thymus, APCs carrying ocular antigens interact with NKT cells, transforming them into NK1.1 Thy regulatory cells that migrate to the spleen and help in the transformation of CD4+ and CD8+ T cells into Treg cells. 2.5 Embryology and Interpretation of Ocular Tissue Changes Table 53.1 ...
