The (endo)cannabinoid system in multiple sclerosis and amyotrophic lateral sclerosis

Area of Science:

• Neuroscience
• Pharmacology

Background:

• The endocannabinoid system (ECS) plays a role in neurological functions.
• Dysregulation of the ECS is implicated in neuroinflammatory and neurodegenerative diseases.

Purpose of the Study:

• To review the alterations of the ECS in multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS).
• To evaluate the therapeutic potential of modulating the ECS in MS and ALS.

Main Methods:

• Literature review of studies on ECS rearrangement in MS and ALS.
• Analysis of data supporting therapeutic agents targeting cannabinoid (CB) receptors and endocannabinoid tone.

Main Results:

• Complex changes in the ECS are observed in both MS and ALS.
• These ECS alterations influence the pathophysiology and clinical manifestations of these diseases.
• Neuroinflammation, microglial activation, oxidative stress, and excitotoxicity are key factors modulated by the ECS.

Conclusions:

• The ECS is significantly altered in MS and ALS.
• Pharmacological modulation of the ECS offers a promising therapeutic strategy for treating MS and ALS.
