| abstract |
Disclosed are nucleic acid vectors comprising a CBh promoter operably linked to a heterologous sequence encoding a G-protein coupled receptor (GPCR). In some embodiments, composition further comprise a sequence encoding an affinity tag, optionally comprising a SNAP polypeptide. In some embodiments, the GPCR comprises a metabotropic glutamate receptor (mGluR), which is optionally, mGluR2. The disclosure also provides compositions and genetically modified cells comprising these vectors. Methods of treatment of retinal diseases and disorders comprising administering compositions, vectors, and cells of the disclosure to a subject in need are also provided. |
