At its core, the RVG29 peptide is a synthesized fragment of the rabies virus glycoprotein. Its primary function stems from its high affinity for the α7 subunit of nicotinic acetylcholine receptors (nAChRs)RVG29-Cys peptide. These receptors are abundantly expressed on neuronal membranes, making them an ideal target for brain-targeting strategies. The peptide's 29-amino acid sequence is optimized for this specific interaction, enabling it to effectively bind to and potentially cross the blood-brain barrier (BBB).
Beyond its direct use, RVG29 is frequently employed to modify various delivery systems. For instance, RVG29-modified exosomes are being explored for their capacity to carry therapeutic payloads like microRNAs (e.g., mir-133b) into the brain, holding potential for treating neurological disorders such as Parkinson's diseaseRVG (RVG29)狂犬病病毒肽（脑靶向肽）《促销中》. Similarly, RVG29-functionalized lipid nanoparticles are designed to enhance the neuronal uptake of drugs and genes, increasing their efficacy and reducing systemic side effects.
