Purpose

Duchenne muscular dystrophy (DMD), caused by dystrophin deficiency,

Results

CBD and CBDV promoted the differentiation of murine C2C12 myoblast cells into myotubes by increasing [Ca2+ ]i mostly via TRPV1 activation, an effect that undergoes rapid desensitization. In primary satellite cells and myoblasts isolated from healthy and/or DMD donors, not only CBD and CBDV but also THCV promoted myotube formation, in this case, mostly via TRPA1 activation. In mdx mice, CBD (60 mg·kg-1 ) and CBDV (60 mg·kg-1 ) prevented the loss of locomotor activity, reduced inflammation and restored autophagy.
