1. 1. An experimental study on the interaction between the neuro-endocrine and immune systems in the gastrointestinal tract

   Författare :Bi-Feng Qian; Eva Ekblad; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gastrointestinal tract; neuro-endocrine system; substance P; vasoactive intestinal polypeptide; vagus nerves; mucosal immune system; T lymphocytes; cytokines; inflammation; mouse;

   Sammanfattning : The mucosa lining of the gastrointestinal (GI) tract is in immediate contact with food nutrients to allow a rapid and efficient digestion and absorption and at the same time protects against the incessant risk of attack from pathogenic microbes. Maintenance of normal physiological activities in the GI tract is dependent on a number of regulatory interactions between the nervous, endocrine, and immune systems, as well as environmental and genetic factors.

3. 2. Genetic Aspects of Environmental Disturbances in Marine Ecosystems : Studies of the Blue Mussel in the Baltic Sea

   Författare :Josefine Larsson; Mats Grahn; Inger Porsch-Hällström; Katarzyna Smolarz; Andrew Whitehead; Södertörns högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Blue mussel; Baltic Sea; anthropogenic disturbance; pollution; sewage effluents; harbors; genetics; genomics; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Sammanfattning : Anthropogenic environmental changes can serve as drivers for evolutionary responses in wild populations. To predict the long-term impact of anthropogenic changes on populations, it is crucial to understand the genetic effects caused by these disturbances. LÄS MER

4. 3. Innate and adaptive cellular immunity in chronic HCV and HIV-1 infection

   Författare :Veronica D Gonzalez; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :HCV; HIV-1; co-infection; adaptive immunity; innate immunity; NK cell; NKT cell; CD4 T cell; CD8 T cell; IFNalpha; ribavirin; immune activation;

   Sammanfattning : Viral infections are initially countered by an innate immune response as a first line of defence followed by an adaptive immune response. However, certain viruses successfully evade cellular immune responses and establish chronic infection. LÄS MER

5. 4. Gastro-intestinal toxicity related to haemopoietic stem cell transplantation with a special focus on the intestinal barrier function

   Författare :Jan-Erik Johansson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The myeloablative, cytotoxic therapy (conditioning treatment) prior to haemopoietic stem cell transplantation (HSCT) has the combined purpose of eliminating leukaemic or cancer cells located in the bone marrow or elsewhere in the body and, in the allogeneic setting, of suppressing the immune response of the recipient to prevent marrow rejection. The unwanted effect is the inevitable elimination of normal, haemopoietic stem cells, a lethal effect which is circumvented by the following administration of haemopoietic stem cells from the patient (autologous HSCT) or from a related or an unrelated donor (allogeneic HSCT).

7. 5. Comparative bioinformatics analyses of transcriptome and epigenome data using bovine model systems

   Författare :Naveed Jhamat; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Bioinformatics methodology is used to understand complex biological processes in molecular biology, genetics and epigenetics. This thesis performed analysis of the complex biological processes controlling reproduction in mammals including dairy cattle. LÄS MER
