Influenza viruses cause acute respiratory infections in humans that result in significant excessive morbidity and mortality rates every year. Current vaccines are limited in several aspects, including laborious manufacturing technology, non-sufficient efficacy, and time-consuming adjustments to new emerging virus variants. An alternative vaccine approach utilizes plasmid DNA encoding influenza virus antigens.

Hereby, the IAV-caused misuse of cellular nuclear factor kappa B (NF-κB) signaling pathways in infected cells represents one target for antiviral therapy. In the present study, pyrrolidine dithiocarbamate (PDTC), which is known as an antioxidant and as an inhibitor of IAV-induced NF-κB activation, was studied in vivo.

Moreover, CVB3 also infects immune cells like CD19+ B lymphocytes, but the viral uptake mechanism into these cells is not well understood. Therefore, primary murine and human CD19+ B cells were isolated by magnetic-activated cell separation technology and analyzed for virus receptor expression, antibody-dependent enhancement of viral infection, and different cellular surface proteins, that might be involved in mechanisms of viral uptake.
