  1. 1. Platelets : intracellular signalling and cellular interaction

    Author : Magnus Grenegård; Hans Gyllenhammar; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Activation of platelets is essential to prevent excessive blood loss at the site of vascular injury. These highly reactive cell fragments are also involved in several pathological conditions, in particular arterial thrombosis, which, in the coronary vessels, can lead to reduced blood flow, vessel occlusion and myocardial infarction.

  2. 2. Alzheimer's disease mutations and cellular signalling

    Author : Monika Vestling; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Alzheimer's disease is the most frequent cause of dementia in elderly and is characterised neuropathologically by the extracellular deposition of amyloid plaques (containing the 39-43 amino acid Abeta peptide), as well as intracellular neurofibrillary tangles (NFTs) composed primarily of an abnormally hyperphosphorylated form of the microtubule-associated protein tau. A proportion (10- 15%) of Alzheimer's disease cases is familial, the remainder being sporadic. READ MORE

  3. 3. Cross-regulation between TGFβ/BMP Signalling and the metabolic LKB1 pathway

    Author : Erna Raja; Aristidis Moustakas; Tomi Mäkelä; Uppsala University Faculty of Medicine Ludwig Institute for Cancer Research; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell signalling; TGFbeta; BMP; LKB1; AMPK; Molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Cell signalling determines physiological responses to many cellular stimuli and environmental changes. The transforming growth factor-beta (TGFβ)/bone morphogenetic protein (BMP) signalling pathways begin by binding of ligand to the heterodimeric receptor complex, followed by activation of Smads that translocate to the nucleus to regulate transcription of genes that further mediate cellular physiology.

  4. 4. Injury-Induced Signalling in Arterial Smooth Muscle Cells

    Author : Sara Moses; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GAG; Clinical biology; Klinisk biologi; proteoglycan; osteopontin; ERK; MAPK; signalling; smooth muscle cell; injury;

    Abstract : The vascular wall is an active, elastic and integrated organ made up of cellular and extracellular matrix (ECM) components. It is not a static organ; the components dynamically change and reorganize in response to physiological and pathological stimuli. Vascular injury induces a complex healing process, analogous to generalised wound healing. READ MORE

  5. 5. Insulin signalling in human adipocytes : mechanisms of insulin resistance in type 2 diabetes

    Author : Anna Danielsson; Peter Strålfors; Fredrik Nyström; Lena Stensson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipocytes; type 2 diabetes; insulin; insulin resistance; insulin signalling; phosphorylation; insulin receptor substrate 1; feedback control; Medical cell biology; Medicinsk cellbiologi;

    Abstract : Prevalensen av fetma ökar drastiskt i stora delar av världen och utgör en stor riskfaktor för att utveckla insulinresistens och typ 2 diabetes. Fettväven kan bli mycket stor om för mycket energi tas upp av kroppen. READ MORE
