MODULATORS OF PURINERGIC RECEPTORS AND RELATED IMMUNE CHECKPOINT FOR TREATING ACUTE RESPIRATORY DISTRESS SYNDROM

摘要

The inventors herein show that purinergic receptors regulate the conversion of macrophage pro-inflammatory reprogramming into anti-inflammatory phenotype in patients suffering from COVID-19 disease. Moreover, they show that P2Y receptor agonists repress NLRP3 inflammasome-dependent IL-1b secretion, but also impair the replication and the cytopathogenic effects of SARS-CoV-2. These results therefore suggest that some purinergic receptors agonists can treat acute lung injury and respiratory disease that are associated with SARS-CoV-2 infection. In addition, their results show that antagonists of the purinergic receptors P2X impair the replication of said virus. The present invention therefore proposes to use purinergic receptors modulators and NLR3-P2Y2R immune checkpoint modulators to treat patients suffering from a virus-induced acute respiratory distress syndrome.
