Cell fate following Fas (CD95) ligand or agonistic anti-Fas antibody stimulation is determined by multiple factors, including Fas expression level, microdomain localization, and modulating cytokines. Highly expressed Fas clusters and activates a canonical apoptosis signaling pathway. In less susceptible cells, Fas transduces apoptosis-independent signals, which are not well defined, but have be...
The heterodimeric laminin receptor α6β4 integrin plays a central role in the promotion of tumor cell growth, invasion, and organotropic metastasis. As an overproduction of the integrin is often linked to a poor prognosis, the inhibition of integrin α6β4 binding to laminin is of high therapeutical interest. Here, we report on the combination of a cell-systematic evolution of ligands by exponenti...
Neurogenesis in the subventricular zone (SVZ) is regulated by diffusible factors and cell-cell contacts. In vivo, SVZ stem cells are associated with the abluminal surface of blood vessels and such interactions are thought to regulate their neurogenic capacity. SVZ neural stem cells (NSCs) have been described to contact endothelial-derived laminin via α6β1 integrin. To elucidate whether heteroce...
Mutational analyses of genes that encode components of the anchoring complex underlying the basolateral surface of external epithelia indicate that this structure is the major element providing for resistance to external friction. Ultrastructurally, laminin 5 (alpha3beta3gamma2; a component of the anchoring filament) appears as a thin filament bridging the hemidesmosome with the anchoring fibri...
BACKGROUND Integrin αvβ3 plays an important role in the regulation of cell proliferation and neoangiogenesis. We found mesangial de novo expression of integrin αvβ3 in mesangioproliferative glomerulonephritis (MesGN). The aim of the study was to clarify if blockade of αvβ3 integrin with the specific αvβ3-blocking cyclic peptide RGDdFV (cRGD) has beneficial effects on the course of this disease....
Bacteria and viruses often use the normal biological properties of host adhesion molecules to infect relevant host cells. The outer membrane bacterial protein invasin mediates the attachment of Yersinia pseudotuberculosis to human cells. In vitro studies have shown that four members of the very late antigen (VLA) integrin family of adhesion molecules, VLA-3, VLA-4, VLA-5, and VLA-6, can bind to...
Speed from recycling n page 545, Strachan and Condic show that neural crest cells (NCCs) can be speedy if they remember to recycle receptors. The speed gained from their conservation efforts may expose them to differentiation pathways that other NCCs miss out on. Populations of NCCs differ in their speed on various matrices. Cranial NCCs, for instance, pick up speed on higher concentrations on ...
