AAV with MBP promoter driven Cre Inducible hChR2(E123T/H134R)-Venus
This AAV expresses DIO-hChR2(E123T/H134R)-Venus driven by an olgiodendricyte MBP promoter.
The myelin basic proteins (MBPs) are a family of polypeptides that are predominantly expressed in the nervous system, where they play a major role in myelination. This 1.3 Kb mouse MBP promoter drives reporter gene expression mainly in oligodendrocytes.
hChR2(E123T/H134R), also known as ChETA, is a channelrhodopsin-2 variant with faster deactivation kinetics.
In the DIO scenario, the transgene of interest is inserted in reverse orientation relative to the 5′ promoter and is flanked by oppositely oriented loxP and lox2272 sites. In the absence of Cre expression, the transgene will not be produced. In the presence of Cre expression, the transgene will be “FLip-EXchanged” or FLEXed, leading to expression of the transgene. This is due to a permanent Cre-mediated recombination/inversion of the flanked transgene. This arrangement is called DIO (double-floxed inverse ORF), Cre-ON, Flex-rev (reverse), Flex-ON/FlexON, or DIO-AAV/AAV-DIO (double-floxed inverse ORF in AAV).
