  1. 21. Dopamine D2 receptor G protein coupling and it's regulation

    Författare :Anton Terasmaa; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dopamine; D2 receptor; G protein; supersensitivity; 6-hydroxydopamine; [3 S]GTP-gamma-S; radioligand binding;

    Sammanfattning : Dopamine (DA) receptors belong to the superfamily of G protein coupled receptors. The D2 DA receptor is negatively coupled with adenylate cyclase via pertussis toxin sensitive (Gi/o) G proteins. LÄS MER

    Sammanfattning : There is sex-bias in morbidity and mortality from infectious diseases. Infections kill more men than women and several studies have pointed out differences in the immune system as a reason. The sex hormones estrogen, progesterone and testosterone all shape the effect of the immune response on multiple levels. LÄS MER

    Sammanfattning : Lipoprotein particles act as lipid transporters in the blood stream, and measuring cholesterol content in specific subclasses of lipoprotein particles has long been, and still is, a frequently used tool to estimate the risk of cardiovascular disease (CVD). High-density lipoprotein (HDL) is a subclass of lipoproteins often regarded as providing protection against CVD via several functions including reverse cholesterol transport and anti-inflammatory capacities.

  5. 24. Chemokine receptor expression and function in experimental autoimmune neuroinflammation

    Författare :Sana Eltayeb; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neuroinflammatory lesions in the central nervous system (CNS) are characterized by the presence of leukocytes, mainly monocytes/macrophages, derived from the systemic compartment. We believe CC inflammatory chemokine receptors (CkRs), CCR1, CCR2 and CCR5 are prerequisite for controlling the migration of monocytes/macrophages into inflammatory foci. LÄS MER

  7. 25. Testosterone and the postmenopausal breast : aspects on cell proliferation and mammographic density

    Författare :Marie Hofling; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Menopause; testosterone; breast cell proliferation; fine needle aspiration biopsy; mammographic density; Syndecan-1; androgen receptor; cynomolgus macaques;

    Sammanfattning : The breast is a target organ for sex steroids, and hormonal treatments have been associated with a risk of breast cancer. There is increasing interest in androgen treatment for postmenopausal women. Testosterone has been shown to improve bone density, body composition, mood, psychosexual function and general well-being.
