At neuronal synapses, multiprotein complexes of trans-synaptic adhesion molecules, scaffold proteins and neurotransmitter receptors assemble to essential building blocks required for synapse formation and maintenance. Here we describe a novel role for the membrane-associated guanylate kinase (MAGUK) protein MPP2 (MAGUK p55 subfamily member 2) at synapses of rat central neurons. Through interact...
The formation of focal adhesions governs cell shape and function; however, there are few measurements of the binding kinetics of focal adhesion proteins in living cells. Here, we used the fluorescence recovery after photobleaching (FRAP) technique, combined with mathematical modeling and scaling analysis to quantify dissociation kinetics of focal adhesion proteins in capillary endothelial cells...
This study was carried out to further characterize the RGD-dependent cell adhesion activity which was previously observed in the vitamin K-dependent matrix Gla protein (MGP) (Loeser, R. F., and Wallin, R. (1992) J. Biol. Chem. 267, 9459-9462). We have found that this cell adhesion activity can be completely removed from the 10-kDa MGP by gel filtration over Sephacryl S-200-HR. The higher molecu...
Understanding how the information is conveyed from outside to inside the cell is a critical challenge for all biologists involved in signal transduction. The flow of information initiated by cell-cell and cell-extracellular matrix contacts is mediated by the formation of adhesion complexes involving multiple proteins. Inside adhesion complexes, connective membrane skeleton (CMS) proteins are si...
Neisseria meningitidis is hosted only by humans and colonizes the nasopharynx; it survives in the human body by reaching an equilibrium with its exclusive host. Indeed, while cases of invasive disease are rare, the number of asymptomatic Neisseria meningitides carriers is far higher. The aim of this paper is to summarize the current knowledge of survival strategies of Neisseria meningitides aga...
The ability of cells to modulate interactions with each other and the substrate is essential for epithelial tissue remodeling during processes such as wound healing and tumor progression. However, despite strides made in the field of proteomics, proteins involved in adhesion have been difficult to study. Here, we report a method for the enrichment and analysis of proteins associated with the ba...
STUDY OBJECTIVES Improved understanding of the phenotypic characteristics of small cell lung cancer (SCLC) cells may facilitate the development of new therapies for this bronchogenic malignancy with early metastases. Herein we investigate whether activation of the M3 subtype of muscarinic acetylcholine receptor (mAChR) expressed on SCLC cells affects beta1-integrin-mediated adhesion of these ce...
Age-related macular degeneration (AMD) may cause severe loss of vision or blindness, particularly in elderly people. Exudative AMD is characterized by the angiogenesis blood vessels growing from underneath macula, crossing blood–retina barrier (which comprises Bruch’s membrane (BM) and retinal pigmentation epithelium (RPE)), leaking fluid into retina knocking off photoreceptors. Here, we simula...
