The neuroprotection of cannabidiol against MPP+-induced toxicity in PC12 cells involves trkA receptors, upregulation of axonal and synaptic proteins, neuritogenesis, and might be relevant to Parkinson’s disease.

“Cannabidiol (CBD) is a non-psychoactive constituent of Cannabis sativa with potential to treat neurodegenerative diseases.

Its neuroprotection has been mainly associated with anti-inflammatory and antioxidant events; however, other mechanisms might be involved.

We investigated the involvement of neuritogenesis, NGF receptors (trkA), NGF, and neuronal proteins in the mechanism of neuroprotection of CBD against MPP+ toxicity in PC12 cells…

This is the first study to report the involvement of neuronal proteins and trkA in the neuroprotection of CBD.

Our findings suggest that CBD has a neurorestorative potential independent of NGF that might contribute to its neuroprotection against MPP+, a neurotoxin relevant to Parkinson’s disease.”
