Dopamine-loaded blood exosomes targeted to brain for better treatment of Parkinson’s disease
Abstract
Parkinson's disease (PD), one of the most common movement and neurodegenerative disorders, is challenging to treat, largely because the blood-brain barrier blocks passage of most drugs. Here we find exosomes from blood showing natural brain targeting ability which involved the transferrin-transferrin receptor interaction. Thus, we develop a biocompatible platform based on blood exosomes for delivering drugs across the blood-brain barrier. Blood exosomes show sizes between 40 and 200 nm and spherical morphology, and dopamine can be efficiently loaded into blood exosomes by a saturated solution incubation method. Further in vitro and in vivo studies demonstrates these exosomes successfully delivered dopamine to brain, including the striatum and substantia nigra. Brain distribution of dopamine increased >15-fold by using the blood exosomes as delivery system. Dopamine-loaded exosomes show much better therapeutic efficacy in a PD mouse model and lower systemic toxicity than free dopamine after intravenous administration. These results suggest that blood exosomes can be used as a promising drug delivery platform for targeted therapy against PD and other diseases of the central nervous system.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
