Currently, CBD’s use as an antiviral therapy for PCC is under exploration, especially since 7-hydroxy-cannabidiol, a derivative of CBD, has been shown to inhibit SARS-CoV-2 replication by blocking viral gene expression, upregulating interferon expression, and downregulating ACE2 and transmembrane protease serine 2 (TMPRSS2) [132,133]. Here, TMPRSS2 is linked to adrenal gland pheochromocytoma.
