1. 6. The role of calcium and calcium-regulated proteins in neutrophil phagocytosis

   Författare :Petra Jerström Skarman; Urban Gullberg; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Neutrophil phagocytosis is an essential component of the innate immunity against invading pathogens. The two types of phagocytosis that are investigated in detail are IgG- and C3bi-mediated phagocytosis. Although the two types are controlled differently, they share the same driving force - reorganisation of the actin cytoskeleton. LÄS MER

3. 7. Mechanisms of Integrin Signal Transduction

   Författare :Anne Stefansson; Staffan Johansson; Annika Armulik; Björn Öbrink; Uppsala universitet; []
   Nyckelord :Cell biology; Integrin; Integrin signalling; PI3K; Akt PKB; Integrin transmembrane domain; cell spreading; Cellbiologi;

   Sammanfattning : Integrins are a protein family of cell surface receptors, expressed in all cell types in the human body, except the red blood cells. Besides their importance in mediating physical connections with the surrounding environment, the integrin family members are also vital signalling mediators. LÄS MER

4. 8. Links between activation and cytoskeletal regulation of B lymphocytes

   Författare :Gediminas Greicius; Edvard Smith; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoological Developmental Biology; zoologisk utvecklingsbiologi;

   Sammanfattning : Interplay between adhesion molecules and the cytoskeleton is involved in many aspects of B lymphocyte behaviour during an immune response. Events such as cell polarisation and locomotion, collaboration with T lymphocytes and segregation in secondary lymphoid tissues all include mechanisms that recognise microenvironment and accordingly adjust morphological features of the cell.
