A heterozygous R1101K mutation of the p150 subunit of dynactin (DCTN1) is reported in a family with amyotrophic lateral sclerosis (ALS) and co-occurrence of frontotemporal dementia (FTD). Two members of our kindred were affected with motor neuron disease and two with dementia in an autosomal dominant pattern of inheritance. We excluded the involvement of(More)
The authors report mutation screening of the p150 subunit of dynactin (DCTN1) and the cytoplasmic dynein heavy chain (DNCHC1) genes in 250 patients with ALS and 150 unrelated control subjects. Heterozygous missense mutations of the DCTN1 gene were detected in one apparently sporadic case of ALS (T1249I), one individual with familial ALS (M571T), two(More)
TRESK (TWIK-related spinal cord K(+) channel) is the most recently identified member of the two-pore-domain potassium channel (K(2P)) family, the molecular source of background potassium currents. Human TRESK channels are not affected by external acidification. However, the mouse orthologue displays moderate pH dependence isolated to a single histidine(More)
A broad-spectrum mercury resistance locus (mer) from a spontaneous chloramphenicol-sensitive (Cms), arginine auxotrophic (Arg-) mutant of Streptomyces lividans 1326 was isolated on a 6 kb DNA fragment by shotgun cloning into the mercury-sensitive derivative S. lividans TK64 using the vector pIJ702. The mer genes form part of a very large amplifiable DNA(More)
Activated mast cells trigger edema in allergic and inflammatory disease. We report a paracrine mechanism by which mast cell-released heparin increases vascular permeability in vivo. Heparin activated the protease factor XII, which initiates bradykinin formation in plasma. Targeting factor XII or kinin B2 receptors abolished heparin-triggered(More)
Posttranslational amyloid-β (Aβ) modification is considered to play an important role in Alzheimer's disease (AD) etiology. An N-terminally modified Aβ species, pyroglutamate-amyloid-β (pE3-Aβ), has been described as a major constituent of Aβ deposits specific to human AD but absent in normal aging. Formed via cyclization of truncated Aβ species by(More)
Virus-like particles with genetically defined envelope proteins were generated from cDNA in order to examine the requirement of Sendai virus haemagglutinin-neuraminidase (HN) protein for particle formation, and the role of fusion protein (F) in receptor binding and membrane fusion. Characterization of particles devoid of HN protein showed that particle(More)
Mice with targeted genetic alterations are the most effective tools for deciphering organismal gene function. We generated an ENU-based parallel C3HeB/FeJ sperm and DNA archive characterized by a high probability to identify allelic variants of target genes as well as high efficiencies in allele retrieval and model revitalization. Our archive size of over(More)
In a comparative study the factors influencing the recovery of recombinant Sendai viruses (SeV) from plasmid based cDNA were analysed systematically in order to establish an efficient and robust method for virus rescue. The amounts and ratios of transfected helper plasmids encoding the viral N, P and L proteins proved to be crucial for virus rescue, and(More)
Treatment by gene replacement is critical in the field of gene therapy. Suitable vectors for the delivery of therapeutic genes have to be generated and tested in preclinical settings. Recently, extraordinary features for a local gene delivery by Sendai virus vectors (SeVV) have been reported for different tissues. Here we show that direct intravenous(More)
