“Because of their neuroprotective properties, cannabinoids are being investigated in neurodegenerative disorders, mainly in preclinical studies. These disorders also include amyotrophic lateral sclerosis (ALS), a degenerative disease produced by the damage of the upper and lower motor neurons leading to muscle denervation, atrophy and paralysis.
The studies with cannabinoids in ALS have been conducted exclusively in a transgenic mouse model bearing mutated forms of human superoxide dismutase-1, the first gene that was identified in relation with ALS.
The present study represents the first attempt to investigate the endocannabinoid system in an alternative model, the transgenic mouse model of TAR-DNA binding protein-43 (TDP-43), a protein related to ALS and also to frontotemporal dementia…
In conclusion, our data support the idea that the endocannabinoid signaling system, in particular the CB2 receptor, may serve for the development of a neuroprotective therapy in TDP-43-related disorders. We are presently engaged in pharmacological experiments to investigate this possibility.”
