Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease caused by the progressive death of motor neurons. Cannabidiol, the second most prevalent cannabinoid in the Cannabis sativa plant, is a potential therapeutic tool for ALS due to its antioxidant, anti-inflammatory, and anti-spasticity effects, as well as its complementary role in treating other neurodegenerative diseases. In SOD1-G93A murine ALS models, cannabinoids have been shown to slow disease progression, extending lifespan and increasing motor function. However, the effects of specific cannabinoids-including cannabidiol-are yet undefined and their functions slowing disease progression are unknown. To advance this understanding we aim to study the effects of cannabidiol treatment in a Caenorhabditis elegans ALS model: a SOD-1 mutant transgenic strain with SOD-1 aggregation in muscular cells. We will use a death assay to measure the lifespan of SOD-1 mutant C. elegans and cannabidiol-treated SOD-1 mutant C. elegans to investigate whether treatment with cannabidiol impacts the lifespan of SOD-1 mutants. To assess mechanosensation, we will touch C. elegans with sutures of various sizes, based on the Von Frey filaments touch response assay in humans. We will develop a novel computational analysis system to measure C. elegans movement in response to touch. We will then compare the motor response of the SOD-1 mutant transgenic strain to wild type and study if cannabidiol modulates a possible change in motor response. This study will evaluate the functions of cannabidiol as a potential therapeutic tool in ALS using a SOD-1 mutant C. elegans model.
