“Coronavirus disease 2019 (COVID-19) is a highly infectious respiratory disease caused by the severe acute respiratory syndrome coronavirus 2. A significant proportion of COVID-19 patients develop Acute Respiratory Distress Syndrome (ARDS) resulting from hyperactivation of the immune system and cytokine storm, which leads to respiratory and multi-organ failure, and death. Currently, there are no effective treatments against hyperimmune syndrome and ARDS.
We propose that because immune cells express cannabinoid receptors and their agonists are known to exhibit potent anti-inflammatory activity, targeting cannabinoid receptors, and endocannabinoids deserve intense investigation as a novel approach to treat systemic inflammation, cytokine storm, and ARDS in patients with COVID-19.”
“The fact that cells of the immune system produce endocannabinoids and express both CB1 and CB2 cannabinoid receptors provides unique opportunities into investigating how the cannabinoid system can be engineered to suppress inflammation using both exogenous and endogenous cannabinoids. Because cannabinoids are potent suppressors of inflammation as evidenced by their ability to suppress cytokine storm in animal models, they may serve as novel therapeutic agents to treat cytokine storm and ARDS that are seen in patients with or without COVID-19. There is a dire need for novel anti-inflammatory agents that exert broad spectrum cytokine suppression associated with ARDS considering that currently up to 40% of such patients, including those with COVID-19, die because currently there are no FDA-approved drugs that are highly effective against cytokine storm and ARDS.”
