Background: Cannabinoid receptors are involved in the neuro-pathogenic mechanisms of inflammatory conditions of the central nervous system and their expression can be modulated during diseases.

Methods: In this manuscript we highlight the function of cannabinoid receptors, their signalling and expression at peripheral and central levels in order to understand their implication in neuro-inflammation and review the effects of cannabinoids in neuro-inflammatory disorders.

Results: Brain inflammatory processes are characterized by infiltration of numerous types of cells: both peripheral and brain resident immune cells and other neuronal cells. The disruption of the blood brain barrier favours cell infiltration in the central nervous system with consequent neuronal damage, a common event in many neuro-inflammatory diseases. Cannabinoids affect brain adaptive and immune response, regulate inflammatory mediators and can exert a role in blood brain barrier damage prevention.

Conclusion: Various patents describe the beneficial properties of cannabinoids in numerous neurodegenerative diseases with inflammatory components and overall effects support the therapeutic application of cannabinoids.
