6. Chemokines and Integrins in Lymphocyte Development and Localization
Sammanfattning : 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.

7. Specific and nonspecific immune mechanisms in human gut : a comparative study of normal and ulcerative colitis intestine
Sammanfattning : The intestine, with its large mucosal surface area, digests and absorbs food nutrients and maintains a beneficial microbial flora in the colon. Local protective immune responses against intestinal pathogens ensure the survival of the individual. These immune reactions are both specific and non-specific in nature. LÄS MER
8. Extrathymic T cell receptor gene rearrangement in human alimentary tract
Sammanfattning : 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. LÄS MER
9. Immune cells in pregnant uterine mucosa : functional properties, cellular composition and tissue organization
Sammanfattning : The pregnant uterus mucosa - decidua - is an "immunologically privileged" site. A semiallogeneic embryo is allowed to survive, develop, and grow while the same tissue implanted outside the uterus will be rejected. The decidua basalis, which participates in the placenta formation, is a tissue rich in lymphoid cells. LÄS MER
10. Studies of innate and adaptive lymphocytes in human liver diseases and viral infections
Sammanfattning : The immune system, including innate and adaptive lymphocytes, is involved in determining the outcome of many human diseases. Two lymphocyte subsets, natural killer (NK) cells and T cells, which are present in both peripheral blood and in tissues, will be further discussed in the context of acute and chronic viral infections and inflammatory liver diseases in this thesis.
