  1. 1. Intracellular regulation of TLR signaling Basic mechanisms and importance in intestinal inflammation

    Författare :Martin Berglund; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TLR IL-1R signalling; Gαi2- - mice; IRAK; peritoneal macrophages; cross-tolerance; dextran sulfate sodium; IBD;

    Sammanfattning : Toll-like receptors (TLRs) recognize conserved structures on/in microorganisms. The intracellular signalling pathways of TLRs are shared with IL-1R and IL-18R and their activation leads to transcription of proinflammatory cytokines and type-I interferons. LÄS MER

  3. 2. The analgesic mechanisms of buprenorphine

    Författare :Poli Francois Kouya; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Buprenorphine; morphine; cross-tolerance; g- opioid receptors; inbred mice.;

    Sammanfattning : Buprenorphine, a derivative of thebaine, is a semi-synthetic opiate and a partial p-opioid receptor agonist. Buprenorphine is also a weak kappa-opioid receptor antagonist. Buprenorphine is used clinically as an analgesic and for maintenance therapy of opiate-dependent subjects because it produces limited withdrawal symptoms. LÄS MER

  4. 3. Genetic differences in neuropathy and opioid responses in rats

    Författare :Aleksandra Bulka; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Allodynia; genetic difference; neuropathic pain; NMDA-receptor; opioids; rat strains; pharmacokinetics; tolerance.;

    Sammanfattning : The studies examined mechanisms and treatments of experimental neuropathic pain with particular emphasis on the differences between rat strains and sub-strains in basal nociceptive sensitivity, development of neuropathic behaviors and sensitivity to opioid analgesia. In order to study the mechanisms that mediate mechanical allodynia (touch-evoked pain) following ischemic nerve injury to the sciatic nerve in rats, the myelinated primary afferents have been examined in the injured and intact nerves.

  5. 4. Impact of Mycobacterium tuberculosis and HIV-1 on innate immune mechanisms

    Författare :Jolanta Mazurek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human immunodeficiency virus type 1 (HIV-1), a causative agent of acquired immunodeficiency syndrome (AIDS), and Mycobacterium tuberculosis (Mtb), a causative agent of tuberculosis (TB), are among the leading causes of death from infectious disease worldwide. Interplay between HIV-1 and Mtb leads to the detrimental dysregulation of immune system mechanisms, which provides the conditions facilitating progression of the disease in co-infected individuals.

  7. 5. Nitric oxide generation from nitroglycerin and other no-donors measured in the lung and studies on nitrate tolerance in the cardiovascular system

    Författare :Per Agvald; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Exhaled; nitric oxide; nitroglycerin; nitrite; temperature; tolerance; hypoxia;

    Sammanfattning : Nitroglycerin (GTN) and compounds referred to as nitrovasodilators or NOdonors are frequently used in the treatment of ischemic heart disease. The common mode of action for these drugs is liberation of nitric oxide (NO). Nitric oxide evokes relaxation of smooth muscle through activation of guanylate cyclase with subsequent formation of eGMP. LÄS MER
