All 12 patients survived and ten had complete neurological and renal function recovery.
Antibodies are probably involved in the pathogenesis of severe neurological symptoms in patients with E coli O104:H4-induced haemolytic uraemic syndrome. Immunoadsorption can safely be used to rapidly ameliorate these severe neurological complications.”
“The architecture of the Golgi apparatus is intimately linked to its role in regulating membrane trafficking. The recruitment of peripheral membrane proteins, in particular golgins and small G proteins has emerged as a key to the understanding of the organization and the dynamics of this organelle. There have been considerable recent advances in defining the structures and binding partners
Nocodazole solubility dmso of golgins, and their contribution to membrane-mediated biological processes. In this paper, we review the proposed roles for golgins with a focus on the golgins of the trans-Golgi network (TGN). We explore the potential for TGN golgins, acting as scaffold molecules, to co-ordinate the regulation of TGN structure and function.”
“A method is presented to produce large amounts of Bcl-2 and Bcl-X-L, two anti-apoptotic proteins of considerable biomedical interest. Expression constructs were prepared in which the Escherichia coli protein TolAIII, known to promote over expression of soluble product, was added to the N-terminus of Bcl-2 or BCl-X-L proteins, which had their C-terminal hydrophobic anchors deleted. Here the expression of these TolAIII-fusion GS-4997 constructs, followed by a two-step metal-affinity based purification protocol is described. The method delivers at least 20 and 10 mg of more than 90% pure TolAIII-Bcl-x(L)Delta C and TolAIII-Bcl-2(2)Delta C proteins, respectively, per liter of E. coli cell culture. The proteins Mephenoxalone are released by proteolysis with thrombin providing > 12mg of Bcl-X-L Delta C or > 6mg of Bcl-2(2)Delta C per liter of E coli cell culture with a purity of more than 95%. Whereas Bcl-X-L Delta C is soluble both before and after TolAIII
removal, Triton X-100 can significantly increase the extraction of TolAIII- Bcl-2(2)Delta C from the bacterial cells and its subsequent solubility. Far-UV CD spectroscopy demonstrated that they both have an alpha-helical structure. Fluorescence spectroscopy was used to quantitatively analyze the binding of the respiratory inhibitor antimycin A to recombinant Bcl-2 and Bcl-XL proteins as well as the displacement of this ligand from the hydrophobic pocket with BH3 Bad-derived peptide. Purified BCl-X-L Delta C and Bcl-2(2)Delta C both protect isolated mitochondria from Bax-induced release of cytochrome c. The ensemble of data shows that the expressed proteins are correctly folded and functional. Therefore, the TbIAIII-fusion system provides a convenient tool for functional characterization and structural studies of anti-apoptotic proteins. (c) 2008 Elsevier Inc. All rights reserved.
