Pseudotyping

from Wikipedia, the free encyclopedia

As pseudotyping (engl. Pseudotyping ) of the exchange which is the viral envelope proteins in the production of viral vectors , respectively. This creates pseudotype vectors. The envelope proteins of the virus are replaced by foreign viral envelope proteins. In this way, various changes in the vector can be generated, which among other things cause a change in the tropism compared to the host cells or an increased stability of the virus particle. The pseudotypes are not genetically determined.

Pseudotyping enables, for example, the investigation of specific properties of the virus envelope proteins. A frequently used coat protein is the glycoprotein G of the vesicular stomatitis virus (VSV), abbreviated VSV-G . This envelope protein enables the transduction of almost all cell types .
