A rabies viral polypeptide (of 29 amino acids) modified red blood cell membrane (RBCm) was used to encapsulate curcumin nanocrystals (RVG29-RBCm/Cur-NCs), and this nanodecoy delivery of curcumin was able to inhibit α-syn aggregation, restore the number of TH-positive neurons, and attenuate motor deficits in a mouse model of PD [62]. This evidence concerns the gene TH and Parkinson disease.
