1. 1. Human intraepithelial lymphocytes : a comparative study of phenotype, morphology, and functional properties of intraepithelial lymphocytes in gut and oral mucosa

   Författare :Carina Lundqvist; Marie-Louise Hammarström; Sten Hammarström; Per Brandtzaeg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intraepithelial lymphocytes; alimentary tract; intestinal epithelium; gut luminal antigens; gingiva; γδ T cells; immunoelectron microscopy; cytokine mRNA; RT-PCR; extrathymic T cell maturation; RAG-1; periodontitis; mucosal immune system; CD4-CD8- αβ T cells; CD8 γδ T cells;

   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

3. 2. Human intestinal T lymphocytes : a comparative analysis of phenotype and function in normal and inflamed mucosa

   Författare :Silvia Melgar; Nadine Cerf-Bensussan; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestinal mucosa; intraepithelial lymphocyte; lamina propria lymphocyte; γδ T cell; regulatory T cell; cytotoxicity; cytokine; basal lymphoid aggregate; ulcerative colitis; Crohn s disease;

   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

4. 3. T-cells in COPD to help or harm? A study of T-cells in COPD patients and related aspects of T-cell function in vitro

   Författare :Pernilla Glader; allergologi och palliativ medicin Lungmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Andningsorganen; Respiratory system; Immunologi; serologi; T-cell; inflammation; mucosal immunology; transplantation; serology; Immunology; lymphocyte; chronic obstructive pulmonary disease;

   Sammanfattning : Chronic obstructive pulmonary disease, COPD, is manifested by chronic airflow limitation due to inflammation and tissue destruction in the lungs. COPD is caused primarily by smoking and with increasing cigarette consumption in the world, the prevalence for COPD will most probably increase in the future. LÄS MER

5. 4. Butyrophilin- and Butyrophilin-like genes and their role in epithelial cell-intraepithelial T lymphocyte cross-talk

   Författare :Cristina Lebrero-Fernandez; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Butyrophilin-like Btnl ; Butyrophilin Btn ; Intraepithelial lymphocytes IELs ; Mucosal immunity; Intestinal epithelial cells; γδ T cells; Intestinal inflammation; Colon cancer; Ulcerative colitis;

   Sammanfattning : More than 50% of our immune system is located in the gut. The intestinal epithelium, which forms an interface between the organism and the environment, harbors intraepithelial lymphocytes (IELs) that comprise a mixture of conventional αβ T cells and unconventional αβ- and γδ T cells.

7. 5. Adaptive immune response in the intestinal mucosa of microscopic colitis patients

   Författare :Ashok Kumar Kumawat; Elisabeth Hultgren-Hörnquist; Johan Bohr; Curt Tysk; Allan Sirsjö; Samuel Lundin; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microscopic colitis; collagenous colitis; lymphocytic colitis; intraepithelial lymphocytes; lamina propria lymphocytes; T cell receptor excision circle; T helper cells; cytotoxic T lymphocyte and mucosal cytokines; Biomedicin; Biomedicine;

   Sammanfattning : Microscopic colitis (MC) is a chronic diarrhoeal disease of unknown aetiology, comprising collagenous colitis (CC) and lymphocytic colitis (LC). The nature of the adaptive local immune responses in the mucosa of MC patients is however far from elucidated. LÄS MER
