Abstract
According to some embodiments herein, expression systems and methods for activity-dependent transcription of nucleic acids are provided. In some embodiments, adeno-associated viral vector systems comprise an immediate early gene promoter operably linked to a transcriptional activator. The transcription activator can be fused to an N-terminal portion of an immediate early gene, for example fos.
Claims14
An activity-dependent adeno-associated virus (AAV) vector expression system comprising:
- an immediate early gene (IEG) promoter operably linked to a converter nucleic acid encoding a converter comprising an N-terminal portion of FOS fused to a nucleic acid encoding an activator, wherein the activator is downstream of the N terminal portion of FOS;
- and
- a regulatable promoter operably linked to an insertion site for a transcript-encoding nucleic acid, wherein transcription by the regulatable promoter is activated by the activator, and
- wherein the activator's activation of the regulatable promoter is modulated by a transcriptional modulator compound, if present.
