Poster Title

New strategies to produce pseudotyped viruses to study entry of

Flaviviruses

Synopsis

A pseudotyped virus (PV) is a viral particle harbouring the core structure of one virus and the envelope

(Env), the viral protein which interacts with the cellular receptor mediating entry, of a heterologous virus:

these PV have been largely employed in gene therapy, serology and virus-host interaction studies. The

use of PV is particularly important to study viruses classified as hazard group 3 and 4, as they can be

handled at a lower containment level (BSL1/2) and do not require enhanced security, such examples are

Ebola and other filoviruses, Lassa fever, Coronaviruses. However, those viruses which assemble within the

intracellular membrane systems are particularly difficult to pseudotype, as the incorporation of their Env

on the surface of a PV is compromised by the endoplasmic reticulum (ER) retention signal present on their

Env. These include viruses which have caused or have the potential to cause an outbreak such as

flaviviruses, e.g. Zika virus, Dengue virus and Japanese Encephalitis virus (IEV).
