  1. 6. The Role of Zinc in Leishmaniasis and Tuberculosis

    Författare :Miguel Guzman; Tillämpad biokemi; []
    Nyckelord :Cutaneous leishmaniasis; tuberculosis; zinc supplementation; lymphocytes; cell proliferation; INF-γ; CD4 CD8 ratio;

    Sammanfattning : The synergistic relation between nutritional deficiency and infection may have negative effects on the immune system, making individuals more vulnerable to infection. Zinc can affect the resistance to infections by modulating cytokine release, and by acting as a cofactor of thymulin, which induces the differentiation of immature T lymphocytes. LÄS MER

  3. 7. Chemokines and Integrins in Lymphocyte Development and Localization

    Författare :Jan Marsal; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunologi; serologi; transplantation; serology; Immunology; homing; development; IEL; lymphocytes; chemokines; integrins;

    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.

  4. 8. Applications in Surface Enhanced Raman Spectroscopy

    Författare :Charlotte Eliasson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SERS; surface enhanced Raman spectroscopy; image analysis; lymphocytes; PCA; doxorubicin; living cells; PLS;

    Sammanfattning : The aim of this thesis is to address specific applications of Raman spectroscopy and specifically surface enhanced Raman spectroscopy, SERS. It includes an introduction to the techniques and several applications. The focus has been on how to achieve high precision SERS measurements, both qualitatively and quantitatively. LÄS MER

  5. 9. Immune maturation and lymphocyte characteristics in relation to early gut bacteria exposure

    Författare :Sophia Björkander; Eva Sverremark Ekström; Hanne Frøkiær; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Allergy; cell-free supernatant; chemokines; colonization; cytokines; FOXP3; immune-maturation; lactobacilli; lymphocytes; NK-cells; Staphylococcus aureus; unconventional T-cells; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : At birth, the immune system is immature and the gut microbiota influences immune maturation. Staphylococcus aureus (S. aureus) and lactobacilli are part of the neonatal gut microbiota and have seemingly opposite effects on the immune system. S. LÄS MER

  7. 10. Studies on stress in African green monkeys (Cercopithecus aethiops) : Stress associated cortisol and prolactin levels, lymphocyte modulation and pathological changes in adrenal cortex, stomach and hippocampus in the African green monkey (C. aethiops)

    Författare :Mbaruk Abdalla Suleman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; adrenal cortex; capture; confinement; cortisol; husbandry; housing; hippocampus; lymphocytes; prolactin; stomach; stress; wild; African green monkeys; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : African green monkeys (AGMs) are highly susceptible to captivity-induced stress. An investigation of spontaneous deaths of laboratory confined AGMs at the Institute of Primate Research, Nairobi, Kenya over a period of 7.5 years documented mild to severe gastric mucosal erosions and ulcers in 83 of 260 (32%) necropsies.
