Characterization of neutralizing monoclonal antibody against tick-borne encephalitis virus in vivo.

Tick-borne encephalitis virus (TBEV) is the most important tick-transmitted pathogen in the family Flaviviridae and causes one of the most severe human neuroinfections. In this study, a neutralizing mouse mAb 14D5, which was previously shown to have cross-reactive binding to several flaviviruses belonging to the TBEV group, was examined for its prophylactic and therapeutic effects in BALB/c mice infected with TBEV. Before and after infection, mice were administrated mAb 14D5 at doses 100 μg and 10 μg per mouse.

Post-exposure administration of chimeric antibody protects mice against European, Siberian, and Far-Eastern subtypes of tick-borne encephalitis virus.

Tick-borne encephalitis virus (TBEV) is the most important tick-transmitted pathogen. It belongs to the Flaviviridae family and causes severe human neuroinfections. In this study, protective efficacy of the chimeric antibody chFVN145 was examined in mice infected with strains belonging to the Far-Eastern, European, and Siberian subtypes of TBEV, and the antibody showed clear therapeutic efficacy when it was administered once one, two, or three days after infection.

Correction to: Role of β Cell Precursors in the Regeneration of Insulin-Producing Pancreatic β Cells under the Influence of the Pegylated Form of Glucagon-Like Peptide 1.

The title of the article should read:"Role of β Cell Precursors in the Regeneration of Insulin-Producing Pancreatic β Cells under the Influence of the Pegylated Form of Glucagon-Like Peptide 1".

Role of β Cell Precursors in the Regeneration of Insulin-Producing Pancreatic β Cells under the Influence of Glucagon-Like Peptide 1.

The effects of the pegylated form of glucagon-like peptide 1 (pegGLP-1) on oligopotent β cell precursors (CD45TER119CD133CD49f) in the pancreas were studied in C57Bl/6 mice. Under conditions of streptozotocin-induced type 1 diabetes mellitus, intraperitoneal injection of pegGLP1 increased the content of β cell precursors and dithizone-stained cells in the pancreas. β Cell precursors of mice with diabetes demonstrated high self-maintenance potential.

Multilocus sequence analysis of Borrelia burgdorferi sensu lato isolates from Western Siberia, Russia and Northern Mongolia.

Lyme borreliosis (LB) is the most frequently recorded tick-transmitted disease in Eurasia. Tomsk Province, Western Siberia in Russia and Selenge Aimag in Northern Mongolia are leading regions in the LB incidence rate in these countries. Spirochaetes of the Borrelia burgdorferi sensu lato (s.
