11. Transforming Growth Factor-b, Regulatory functions on normal lymphocytes and tumor outgrowth Regulatory functions on normal lymphocytes and tumor outgrowth
Abstract : Transforming growth factor-beta (TGF-b) is a well-characterised growth regulatory factor, which acts on most cell types. This thesis has focused on the regulatory roles of TGF-b on normal lymphocytes. One interesting finding is that TGF-b acts both costimulatory and inhibitory on T-lymphocytes. READ MORE

12. Chemokines and Integrins in Lymphocyte Development and Localization
Abstract : The small intestine contains a large number of T lymphocytes within the single-layered epithelium that separates the gut lumen from the lamina propria. These intraepithelial T lymphocytes have potent cytolytic and immunoregulatory capacities, thought to be important for fighting infections, neoplastic growth, and sustaining epithelial integrity.

13. Chemokine Receptor CCR9: Studies on the Generation and Localization of Gut Tropic Lymphocytes
Abstract : Lymphocytes are important mediators of adaptive immune responses. Naive T lymphocytes circulate in the blood and lymph between different secondary lymphoid organs in search for their specific antigen. READ MORE

14. T cell Tolerance - Cellular and molecular features of immune regulation
Abstract : The immune system has evolved regulatory mechanisms in order to balance the effects of deleterious immune responses. Such immunological tolerance may be specifically acquired by lymphocytes, although different cells of the immune system participate in the induction and maintenance of tolerance. READ MORE

15. Extrathymic T cell receptor gene rearrangement in human alimentary tract
Abstract : T lymphocytes regulate the initiation, duration, and magnitude of adaptive immune responses and function as effector cells in cell mediated immunity. To become immunologically competent they must generate functional antigen receptors. This process takes place in the thymus and requires somatic recombination of T cell receptor (TCR) genes. READ MORE
