We present a murine model that examines the effects of macrophage-produced apolipoprotein E3 (apoE3) and apoE4 on VLDL and high density lipoprotein (HDL) metabolism. Mice expressing apoE3 on the Apoe−/− background had substantially lower VLDL lev

Apolipoprotein (apo) E4 increases the risk and accelerates the onset of Alzheimer's disease (AD). However, the underlying mechanisms remain to be determined. We previously found that apoE undergoes proteolytic cleavage in AD brains and in cultured ne

A series of mutants incorporating furin recognition sequences within the P6-P1 region of the reactive site loop of alpha(1)-antitrypsin were constructed. Variants containing different combinations of basic residues in the P1, P2, P4, and P6 positions

The x-ray crystal structure of the serpin-proteinase complex is yet to be determined. In this study we have investigated the conformational changes that take place within antitrypsin during complex formation with catalytically inactive (thrombin S195

Protease cascades and their inhibitors are a common feature of many biological regulatory systems, and the various components of such cascades have been subjected to a long and concerted evolution. We present here evidence that in the coagulation cas

A number of disease states are attributable to α 1 -antitrypsin polymerisation within the endoplasmic reticulum of hepatocytes and subsequent plasma deficiency. Two distinct mechanisms describing the process of α 1 -antitrypsin polymerisation have

Serpin polymerization is the underlying cause of several diseases, including thromboembolism, emphysema, liver cirrhosis, and angioedema. Understanding the structure of the polymers and the mechanism of polymerization is necessary to support rational

The hinge region of serpins is a conserved sequence of 8 amino acids located 7 residues away from the scissile bond at P8 to P15, on the edge of the protease-binding domain. In the inhibitory serpins the P8 to P12 residues of this motif are usually s

Recombinant alpha 1-antitrypsin with a P1 arginine residue (Arg-alpha 1-antitrypsin) is a rapid inhibitor of both thrombin and activated protein C (APC). A series of mutants were made in an attempt to increase the specificity of this serpin for throm

The importance of interactions with residues 15-21 in the core domain of hirudin for the formation of the complex with thrombin has been investigated by site-directed mutagenesis. Contacts made by Leu-15 were found to be particularly important; repla
