Background: Leukocyte activation results in a rapid increase in adhesion to the extracellular matrix due to the activation of β1 integrin receptors. A role for phosphatidylinositol (PI) 3-kinase in integrin activation has been proposed, as activation of integrins by many receptors can be blocked by PI 3-kinase inhibitors. One receptor that regulates integrins is the CD28 surface antigen; here, ...
background: the ovariectomized animals are good models to evaluate the effect of different steroid hormone treatments on implantation events and the pattern of integrin expression. therefore, this study was performed to compare the expression of integrins and osteopontin (opn) in correlation with pinopode development in ovariectomized mice endometrium which was subjected to steroid hormones. me...
Integrins belong to a large family of αβ heterodimeric transmembrane proteins first recognized as adhesion molecules that bind to dedicated elements of the extracellular matrix and also to other surrounding cells. As important sensors of the cell microenvironment, they regulate numerous signaling pathways in response to structural variations of the extracellular matrix. Biochemical and biomecha...
Caveolae are specialized compartments of the plasma membrane that are involved in signaling, endocytosis, and cholesterol transport. Their formation requires the transport of caveolin-1 to the plasma membrane, but the molecular mechanisms regulating the transport are largely unknown. Here, we identify a critical role for adhesion-mediated signaling through β1 integrins and integrin-linked kinas...
The underlying mechanisms allowing West Nile virus (WNV) to replicate in a large variety of different arthropod, bird and mammal species are largely unknown but are believed to rely on highly conserved proteins relevant for viral entry and replication. Consistent with this, the integrin αvβ3 has been proposed lately to function as the cellular receptor for WNV. More recently published data, how...
