  1. 16. Signal transduction in the brain : modulation of receptor-mediated inositol phospholipid breakdown by potassium and fluoride ions

    Författare :Gunnar Tiger; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inositol phospholipid breakdown; muscarinic receptors; potassium; fluoride; rat brain; pig brain;

    Sammanfattning : Neurotransmitter receptor types mediating the generation of intracellular signals are of two types; ligand-gated ion channels and G protein coupled receptors. The effector enzyme phosphoinositide-specific phospholipase C (PLC) is modulated by stimulation of G protein coupled receptors, leading to an increased breakdown of inositol phospholipids ("Ptdlns breakdown").

  3. 17. Autoimmunity in Africa: Comparing Systemic Lupus Erythematosus and Anti-phospholipid Antibodies in Sudan and Sweden

    Författare :Sahwa Elbagir; Johan Rönnelid; Iva Gunnarsson; Amir I Elshafie; Bo Nilsson; Cem Gabay; Uppsala universitet; []
    Nyckelord :SLE; anti-phospholipid antibodies; IgA; immune complexes; pregnancy; autoimmunity; Sudan; Africa; Klinisk immunologi; Clinical Immunology;

    Sammanfattning : Systemic Lupus Erythematosus (SLE) is a chronic immune complex (IC)-mediated disease with variable prevalence worldwide, reported to be more common in Africans, Hispanics and Asians than in Caucasian populations. Expression of autoantibodies might vary between different ethnic populations due to environmental and genetic factors. LÄS MER

  4. 18. On the Formation of Supported Phospholipid Bilayers

    Författare :Erik Reimhult; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vesicle adsorption; formation kinetics; SPR; QCM-D; SPB; AFM; supported lipid bilayer; supported membrane; liposome;

    Sammanfattning : Lipid bilayers are a central component of both the structure and function of biological membranes, like the one surrounding cells of living organisms. Since the lipid bilayer provides a host matrix for membrane proteins, which perform many of the specialized tasks in cells like energy, signal and material transduction, researchers have tried to develop artificial model membranes to study a variety of membrane protein functions.
