  1. 16. The eukaryotic ribosome in focus : a chemical footprinting analysis of ribosome-ligand interactions in in vivo assembled complexes

    Författare :Marika Salonen Sloma; Diarmaid Hughes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; Zoological Cell Biology; zoologisk cellbiologi;

    Sammanfattning : Protein synthesis is an essential biological process that occurs on ribosomes. The process requires an involvement of numerous components like mRNA, tRNA and translation factors. The mammalian 80S ribosome, the focus of this thesis, is composed of four rRNAs and approximately 80 proteins distributed in two subunits the 40S and 60S subunit. LÄS MER

  3. 17. ATP Dynamics in Pancreatic α- and β-cells

    Författare :Jia Li; Anders Tengholm; Erik Gylfe; Hindrik Mulder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATP; Ca2 ; β-cell; α-cell; SERCA; SOCE; muscarinic receptor; insulin secretion; glucagon secretion; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Glucose metabolism in pancreatic α- and β-cells is believed to regulate secretion of glucagon and insulin, respectively. In β-cells, ATP links glucose metabolism to electrical activity and insulin secretion. LÄS MER

  7. 20. Pro- and anti-inflammatory regulation of β2 integrin signalling in human neutrophils

    Författare :Veronika Brodin Patcha; Eva Särndahl; Emmanuelle Caron; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inflammation; neutrophils; signalling; integrins; Cell biology; Cellbiologi;

    Sammanfattning : The body is under constant attack from pathogens trying to slip by our immune defence. If the barrier is breached, invading pathogens enter the tissues and cause inflammation. During this process neutrophils, constituting the first line of defence, leave the bloodstream and seek out and kill the invading pathogens. LÄS MER
