EF1a-hM3D(Gq)-mCherry AAV (Serotype 9)

EF1a-hM3D(Gq)-mCherry AAV (serotype 9) is a genetically engineered viral vector designed for advanced neurological research and therapeutic applications. This adeno-associated virus (AAV) belongs to serotype 9 and is known for its excellent transduction ability, capable of transducing a wide range of tissue types, with particular proficiency in the central nervous system. Its high efficiency in penetrating the blood-brain barrier makes it a valuable tool for delivering genetic material to neurons and other cells in the brain.

The construct within this specific AAV particle is designed to express the hM3D(Gq)-mCherry fusion protein. The hM3D(Gq) component is part of the designer G protein-coupled receptor (GPCR) in the DREADDs (Designer Receptors Activated Only by Designer Drugs) technology. This modified receptor is designed to be activated by an otherwise inert ligand, typically clozapine-N-oxide (CNO), allowing precise control of signaling pathways in receptor-expressing cells. Activation of hM3D(Gq) typically results in the stimulation of phospholipase C, which plays a key role in various intracellular signaling processes, leading to increased neural excitability. mCherry is a fluorescent protein that can be used as a reporter gene to facilitate visualization and confirmation of expression within target tissues. Scientists can use this property to ensure that AAV has successfully transduced the target area and evaluate the expression levels achieved.
