  2. 1. Molecular targets for glucocorticoids in macrophages: cytosolic phospholipase A2 and cytokine formation

    Author : Karin Gewert; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; signal transduction; dexamethasone; cytosolic phospholipase A2; glucocorticoids; macrophages; protein kinase C; mitogen-activated protein kinases; TNF-alpha; IL-1beta; protein phosphatases; okadaic acid; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : The aim of this investigation has been to study mechanisms by which glucocorticoids inhibit inflammatory processes in vitro. Type IV cytosolic 85 kDa phospholipase A2 (cPLA2) is an important modulator of inflammatory responses that is present in macrophages as well as in other cell types. READ MORE

  4. 2. In vitro cellular models for neurotoxicity studies : neurons derived from P19 cells

    Author : Dina Popova; Jacobsson Stig O.P.; Anna Forsby; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurotoxicity; Neuronal cell culture; P19 cells; SH-SY5Y cells; βIII-tubulin; Methylmercury; Okadaic acid; Acrylamide; MDMA; Piperazine-derived designer drugs.;

    Abstract : Humans are exposed to a variety of chemicals including environmental pollutants, cosmetics, food preservatives and drugs. Some of these substances might be harmful to the human body. READ MORE

  5. 3. Protein phosphorylation cascades regulating islet beta-cell insulin exocytosis through glucose sensing and drug signaling : with special focus on serine/threonine protein phosphates and hypoglycemic sulfonylureas

    Author : Mikael Lehtihet; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Diabetes; Islet; Insulin; Exocytosis; Protein phosphatase; Protein kinase; CPT-1; Sulfonylurea; Glutamate; Polyphosphoinositide;

    Abstract : In human type 2 diabetes, loss of glucose-sensitive insulin secretion from the pancreatic �-cell is an early pathogenetic event. Initially, this may be compensated for by stimulating insulin secretion by sulfonylurea drugs. READ MORE

  6. 4. Studies of nucleotide receptors-induced calcium response in glomerular mesangial cells and afferent arterioles

    Author : Antonio M. Gutiérrez; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mesangial cells; nucleotide receptors; purinoceptors; desensitization; afferent arterioles; ATP; UTP; adenosine; protein phosphatases; calcium; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : It is known that intracellular calcium concentration ([Ca2+]i) changes in rat glomerular mesangial cells (GMC) and rabbit afferent arterioles (AA) in response to extracellular nucleotides. We studied the nucleotide-induced calcium response in cultured GMC and AA. READ MORE

  7. 5. TNFalpha expression in monocytes/macrophages

    Author : Karolina Andersson; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper allmänt ; General biomedical sciences; Protein kinase; Macrophage; TNF;

    Abstract : The recognition of microbes or microbial products by leukocytes is a key event in innate immunity. Binding of microbial products to cell surface receptors on phagocytes induce a response that includes the production of inflammatory mediators. One such mediator is the cytokine tumour necrosis factor alpha (TNF). READ MORE
