  1. 16. Membrane lipids and their transfer proteins in β-cells

    Författare :Beichen Xie; Olof Idevall-Hagren; Anders Tengholm; Jen Liou; Uppsala universitet; []

    Sammanfattning : Insulin secretion from β-cells is essential for glucose homeostasis and is often dysregulated in diabetes. Intracellular Ca2+ and membrane lipids cooperate to control insulin secretion with high spatial and temporal precision. LÄS MER

  3. 17. On neuroinflammation in psychotic disorders

    Författare :Carl Sellgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neuroinflammation has been implicated in several psychiatric conditions. Based on experimental studies, the glia-derived tryptophan metabolite kynurenic acid (KYNA) may be especially relevant for positive psychotic symptoms and impaired executive functioning. LÄS MER

  4. 18. Experimental inhibition of proliferative retinopathy

    Författare :Sylvia Almlöf Sarman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Retinal ischemic diseases like retinopathy of prematurity (ROP), diabetic retinopathy (DRP) and retinal vein occlusion, with preretinal neovascularization (angiogenesis) that may lead to vitreous hemorrhages and retinal detachment with subsequent vision loss and blindness is a global health problem. By analyzing the potential role of molecules acting at different levels of the angiogenic cascade the presented studies aimed to widen our understanding of retinal ischemic diseases on a molecular, cellular and morphologic level.

  5. 19. The role of red blood cells in cardiac and endothelial dysfunction in cardiometabolic disease

    Författare :Tong Jiao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Cardiometabolic disease, which includes the combination of cardiovascular disease, especially coronary artery disease and type 2 diabetes (T2D), is a major health problem and cause of mortality worldwide. ST-elevation myocardial infarction (STEMI) occurs when coronary arteries are occluded and is regarded as a life-threatening disorder. LÄS MER

  7. 20. Autocrine/paracrine interactions moendocrine pancreasdulating hormone release in the endocrine pancreas

    Författare :Over Cabrera; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human islet transplantation is emerging as an alternative to pancreas transplantation or insulin therapy in the treatment of type I diabetes. It has been possible to achieve euglycemia by transplanting isolated human islets in patients who suffer from the long term side effects of diabetes and insulin therapy. LÄS MER
