Isolated integrin beta3 subunit cytoplasmic domains require membrane anchorage and the NPXY motif to recruit to adhesion complexes but do not discriminate between beta1- and beta3-positive complexes.

Integrin adhesion receptors consist of non-covalently linked alpha and beta subunits each of which contains a large extracellular domain, a single transmembrane domain and a short cytoplasmic tail. Engaged integrins recruit to focal structures globally termed adhesion complexes. The cytoplasmic domain of the beta subunit is essential for this clustering. beta1 and beta3 integrins can recruit at distinct cellular locations (i.e. fibrillar adhesions vs focal adhesions, respectively) but it is not clear whether individual beta subunit cytoplasmic and transmembrane domains are by themselves sufficient to drive orthotopic targeting to the cognate adhesion complex. To address this question, we expressed full-length beta3 transmembrane anchored cytoplasmic domains and truncated beta3 cytoplasmic domains as GFP-fusion constructs and monitored their localization in endothelial cells. Membrane-anchored full-length beta3 cytoplasmic domain and a beta3 mutant lacking the NXXY motif recruited to adhesion complexes, while beta3 mutants lacking the NPXY and NXXY motifs or the transmembrane domain did not. Replacing the natural beta subunit transmembrane domain with an unrelated (i.e. HLA-A2 alpha chain) transmembrane domain significantly reduced recruitment to adhesion complexes. Transmembrane anchored beta3 and cytoplasmic domain constructs, however, recruited without discrimination to beta1- and beta3-rich adhesions complexes. These findings demonstrate that membrane anchorage and the NPXY (but not the NXXY) motif are necessary for beta3 cytoplasmic domain recruitment to adhesion complexes and that the natural transmembrane domain actively contributes to this recruitment. The beta3 transmembrane and cytoplasmic domains alone are insufficient for orthotopic recruitment to cognate adhesion complexes.

Hospital disaster preparedness in Switzerland.

STUDY OBJECTIVE: Hospital preparedness is an essential component of any developed health care system. However, there is no national legislation in Switzerland. The objective of this inquiry was to establish the geographic distribution, availability and characteristics of hospital preparedness across Switzerland. METHODS: A questionnaire regarding hospital preparedness in 2006 was addressed to all heads responsible for emergency departments (ED). The survey was initiated in 2007 and finalised in 2012. RESULTS: Of the 138 ED, 122 (88%) returned the survey. Eighty nine EDs (82%) had a disaster plan. CONCLUSIONS: Our study identified an insufficient rate of hospitals in which emergency physicians reported a disaster plan. The lack of national or cantonal legislation regulating disaster preparedness may be partially responsible for this.
