  1. 21. Studies on the influence of sensory stimulation (acupuncture) on neuropeptide release in the saliva

    Författare :Irena Dawidson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :acupuncture; substance P; neurokinin A; calcitonin gene-related peptide; vasoactive intestinal polypeptide; neuropeptide Y; xerostomia; salivary secretion rates;

    Sammanfattning : The aim of this thesis was to elucidate the mechanisms behind the effect of sensory stimulation (acupuncture) on the salivary flow rates of xerostomic patients. We hypothesised that the sensory stimulation activates the sensory and autonomic nervous systems, leading to an increased release of neuropeptides that influence salivary secretion in co-operation with or/and beside the classical neurotransmitters.

  3. 22. Lymphoma studies in patients with Sjögren's syndrome

    Författare :Lilian Vasaitis; Eva Baecklund; Lars Rönnblom; Thomas Mandl; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sjögren s syndrome; primary Sjögren s syndrome; lymphoma; IgG4-related disease; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Patients with primary Sjögren’s syndrome (pSS) are at increased risk of developing malignant lymphoma. The studies in this thesis aim at broadening our understanding of the association between these two conditions. LÄS MER

  4. 23. Regulation of Hedgehog signalling during development and carcinogenesis

    Författare :Marie Fiaschi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hedgehog (Hh) signalling is one of the most important signalling networks in the body and, when miss-regulated, has been implicated in many human tumours, particularly that of skin (Basal Cell Carcinoma, BCC) and brain (medulloblastoma). BCC most commonly arises due to mutations in the gene sequence of the Hh receptor protein PATCHED1 (PTCH1). LÄS MER

  5. 24. Saliva: a cell suspension of epithelial cells harboring the antimicrobial peptide LL-37 and the growth factor EGF

    Författare :Alexandra Aidoukovitch; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Saliva; Oral health; Innate immunity; Cathelicidin; LL-37; Host defense peptides; EGF; Saliva; Oral health; Innate immunity; Cathelicidin; LL-37; Host defence peptides; EGF;

    Sammanfattning : Saliva plays a crucial role in maintaining oral health through its physical and chemical properties that provide various protective functions. One of its essential components is the human host defense peptide LL-37, which is produced by immune cells and epithelial cells, and participates in the first line of defense against pathogens.

  7. 25. Drosophila immune responses in a model for epithelial hypertrophy

    Författare :Robert Krautz; Ulrich Theopold; Hugo Stocker; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Biology; molekylärbiologi;

    Sammanfattning : Apoptosis, differentiation and proliferation have to be tightly balanced and thus regulated to maintain tissue homeostasis. Stress, metabolic cues, genetic variability, infections and physiological host-commensal interactions influence this balance and thus need to be integrated. Therefore, beyond the discrimination between self and non-self (i.e. LÄS MER
