1. Human intraepithelial lymphocytes : a comparative study of phenotype, morphology, and functional properties of intraepithelial lymphocytes in gut and oral mucosa
Sammanfattning : Human intraepithelial lymphocytes (IEL) constitute a unique cell population situated in the first line of defense of the alimentary tract. Here they are continuously exposed to a massive antigenic load of high complexity. However, different conditions prevail along the alimentary tract. LÄS MER
2. Human intestinal T lymphocytes : a comparative analysis of phenotype and function in normal and inflamed mucosa
Sammanfattning : The epithelial lining of the gut must allow immediate contact with beneficial components as nutrients and normal microflora. At the same time it runs the constant risk of attack from pathogenic microbes and noxious agents. LÄS MER
3. 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
4. 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
5. Human vaginal epithelial immunity and influences of hormonal contraceptive usage
Sammanfattning : The vagina is the port of entry for sexually transmitted diseases in women. Its epithelium constitutes the luminal border, thus comprising an important defence barrier. LÄS MER
