  1. 1. The Francisella pathogenicity island : its role in type VI secretion and intracellular infection

    Författare :Lena Meyer; Anders Sjöstedt; Siobhan C. Cowley; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella; FPI; Type VI Secretion; Igl; DotU; VgrG; Pdp; microinjection; phagosomal escape; intracellular replication; Clinical Bacteriology; klinisk bakteriologi;

    Sammanfattning : Intracellular bacteria have developed various mechanisms to enter and persist in host cells and, at the same time, to evade the host immune response. One such pathogen is Francisella tularensis, the etiological agent of tularemia. LÄS MER

  3. 2. Mechanisms of defective insulin secretion in type 2 diabetes

    Författare :Taman Mahdi; Diabetes - öpatofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; type 2 diabetes; Insulin secretion; TCF7L2; ADRA2A; KCNQ1; SFRP4; interleukin-1B;

    Sammanfattning : Defective insulin secretion from the pancreatic B-cells is a central feature in type 2 diabetes (T2D). There is a strong hereditary component in type T2D, but the underlying pathophysiology remains largely unknown. LÄS MER

  4. 3. New aspects of voltage-gated calcium channel regulation in pancreatic beta-cells - Relevance for insulin release and type 2 diabetes

    Författare :Thomas Reinbothe; Diabetes - öpatofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; voltage-gated calcium channels; L-type; insulin secretion; type 2 diabetes;

    Sammanfattning : Voltage-gated Ca2+ channels are essential transducers of cellular signals in many electrically excitable cells. In the pancreatic beta-cell they mediate controlled Ca2+ influx, which is the final trigger for Ca2+ dependent release (exocytosis) of the blood glucose lowering hormone insulin. LÄS MER

  5. 4. Small Molecules as Tools in Biological Chemistry : Effects of Synthetic and Natural Products on the Type III Secretion System

    Författare :Caroline E. Zetterström; Mikael Elofsson; Samuel I. Miller; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Type III secretion; salicylidene acylhydrazide; virulence-blocker; virulence; inhibitor; target identification; neohopeaphenol A; Yersinia pseudotuberculosis; Pseudomonas aeruginosa; Escherichia coli; biologisk kemi; biological chemistry;

    Sammanfattning : The increasing use of antibiotics has led to a huge problem for society, as some bacteria have developed resistance towards many of the antibiotics currently available. To help find solutions to this problem we studied small molecules that inhibit bacterial virulence, the ability to cause disease. LÄS MER

  7. 5. Pathogenesis of type 2 diabetes -role of defects in insulin secretion and insulin sensitivity

    Författare :Devjit Tripathy; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetology; Endokrinologi; sekretion; diabetologi; Endocrinology; secreting systems; Calpain 10 gene; genetics of type 2 diabetes; MODY; Endogenous glucose production; Disposition index; Botnia clamp; IGT; IFG; HOMA; insulin sensitivity; insulin secretion;

    Sammanfattning : Type 2 diabetes is characterised by defects in insulin sensitivity, insulin secretion and increased endogenous glucose production. The relative contribution of each of these defects remains controversial. LÄS MER
