  1. 21. Chloride Channels and Brown Fat Cells

    Författare :Victor Sabanov; Jan Nedergaard; Bernd Nilius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chloride channel; BAPTA; EGTA; Ca; Animal physiology; Zoofysiologi;

    Sammanfattning : Chloride ion channels are macromolecular pores providing for passage of chloride ions (and certain other inorganic and organic anions) through the cell membrane, down their electrochemical gradients. Chloride channels are differentially expressed in various cells, to best suit specific cellular activities. LÄS MER

  3. 22. Structural Details of Human Aquaporin Regulation : Three stories of three aquaporins

    Författare :Veronika Nesverova; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaporin; membrane proteins; protein trafficking; water channel; aquaporin 0; aquaporin 5; aquaporin 2; cryo-EM; protein phosphorylation; protein-protein interaction; aquaporin regulation; aquaporins;

    Sammanfattning : Every cell is surrounded by a thin plasma membrane, protecting it from its surrounding. Specialized protein channels and transporters are embedded in this membrane, ensuring selective transport of molecules in and out of the cells. To maintain optimal hydration, water channels called aquaporins (AQPs) are present in every cell of our body. LÄS MER

  4. 23. Pulsatile insulin release from single islets of Langerhans

    Författare :Johanna Westerlund; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; islets of Langerhans; insulin; ELISA; cytoplasmic calcium; oscillations; type 2 diabetes; glucose; diazoxide; potassium; tolbutamide; DNP; antimycin A; iodoacetamide; microfluorometry; fura-2; KATP channels; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Insulin release from single islets of Langerhans is pulsatile. The secretory activities of the islets in the pancreas are coordinated resulting in plasma insulin oscillations. Nutrients amplitude-regulate the insulin pulses without influencing their frequency. LÄS MER

  5. 24. Advances in Pharmacological Treatment of Cystic Fibrosis

    Författare :Igor Oliynyk; Godfried M. Roomans; Marie Johannesson; Hugo R. de Jonge; Örebro universitet; []
    Nyckelord :Cystic fibrosis; CFTR; chloride transport; N-acetylcysteine; NO-donors; duramycin; intracellular calcium; azithromycin; MEDICINE; MEDICIN; Medicin; Medicine;

    Sammanfattning : Cystic fibrosis (CF) is an inborn, hereditary disease, due to mutations in the gene for a cAMP-activated chloride (Cl-) channel, the cystic fibrosis transmembrane conductance regulator (CFTR). As a result of impaired ion and water transport,the airway mucus is abnormally viscous, which leads to bacterial colonization. LÄS MER

  7. 25. Host-parasite interactions in the dissemination of Toxoplasma gondii

    Författare :Sachie Kanatani; Antonio Barragan; Per Uhlén; Isabelle Tardieux; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apicomplexa; dendritic cells; microglia; cell migration; 14-3-3 proteins; GABAergic signaling; voltage-dependent calcium channel; host-parasite interaction; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Toxoplasma gondii is an obligate intracellular parasite that infects virtually all warm-blooded organisms. Systemic dissemination of T. gondii in the organism can cause life-threatening infection that manifests as Toxoplasma encephalitis in immune-compromised patients. LÄS MER
