Arginine Methylation by PRMT2 Controls the Functions of the Actin Nucleator Cobl.

The complex architecture of neuronal networks in the brain requires tight control of the actin cytoskeleton. The actin nucleator Cobl is critical for neuronal morphogenesis. Here we reveal that Cobl is controlled by arginine methylation.

Oral vaccination of wildlife against rabies: Differences among host species in vaccine uptake efficiency.

Oral vaccination using attenuated and recombinant rabies vaccines has been proven a powerful tool to combat rabies in wildlife. However, clear differences have been observed in vaccine titers needed to induce a protective immune response against rabies after oral vaccination in different reservoir species. The mechanisms contributing to the observed resistance against oral rabies vaccination in some species are not completely understood.

Proteomic biomarkers for psoriasis and psoriasis arthritis.

Unlabelled: Although several new biomarkers have been recently proposed for psoriasis (Ps) and psoriasis arthritis (PsA), nothing is known about their diagnostic sensitivity and specificity, and their routine use. We therefore searched in-depth for new biomarker candidates using a biobank with EDTA-plasma from 158 individuals, patients and healthy controls. Samples from 6 selected pairs (patients against healthy controls) were searched proteomically using a workflow of extensive and precise design that is highly comprehensive.

Reverse genetics in high throughput: rapid generation of complete negative strand RNA virus cDNA clones and recombinant viruses thereof.

Reverse genetics approaches are indispensable tools for proof of concepts in virus replication and pathogenesis. For negative strand RNA viruses (NSVs) the limited number of infectious cDNA clones represents a bottleneck as clones are often generated from cell culture adapted or attenuated viruses, with limited potential for pathogenesis research. We developed a system in which cDNA copies of complete NSV genomes were directly cloned into reverse genetics vectors by linear-to-linear RedE/T recombination.

The Actin Nucleator Cobl Is Controlled by Calcium and Calmodulin.

Actin nucleation triggers the formation of new actin filaments and has the power to shape cells but requires tight control in order to bring about proper morphologies. The regulation of the members of the novel class of WASP Homology 2 (WH2) domain-based actin nucleators, however, thus far has largely remained elusive. Our study reveals signal cascades and mechanisms regulating Cordon-Bleu (Cobl).

A Dynein Light Chain 1 Binding Motif in Rabies Virus Polymerase L Protein Plays a Role in Microtubule Reorganization and Viral Primary Transcription.

Unlabelled: Rabies virus (RABV) polymerase L together with phosphoprotein P forms the PL polymerase complex that is essential for replication and transcription. However, its exact mechanism of action, interactions with cellular factors, and intracellular distribution are yet to be understood. Here by imaging a fluorescently tagged polymerase (mCherry-RABV-L), we show that L accumulates at acetylated and reorganized microtubules (MT).
