Preclinical Studies of Immunogenity, Protectivity, and Safety of the Combined Vector Vaccine for Prevention of the Middle East Respiratory Syndrome.

The Middle East Respiratory Syndrome (MERS) is an acute inflammatory disease of the respiratory system caused by the MERS-CoV coronavirus. The mortality rate for MERS is about 34.5%.

A new method of producing NS5A antigen of hepatitis C virus.

A task of creating a universal platform for engineering affordable recombinant producers of viral proteins conserving immunogenicity has not been solved yet. High toxicity of the viral proteins for the host cells, low yield and abnormal folding of the products often present severe obstacles to obtaining producers of the viral proteins. In this work, we report a new method of engineering and screening of deletion libraries from the viral antigen genes.

Simulation of Viral Hepatitis E in Marmosets.

We developed a model of hepatitis E virus infection in common marmosets (Callithrix jacchus) and determined optimal route of infection, duration, clinical and virological characteristics of infection in laboratory animals. Using this model, we demonstrated that replication of hepatitis E virus primarily occurs in the liver, while virus replication presumed to take place in the intestine was not confirmed in this experiment.
