Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 and for which there are currently no approved treatments. Here, the principal investigator reported according to previous studies and research findings that Isotretinoin can strongly affect both inflammation and viral entry in severe acute respiratory syndrome coronavirus 2 infection via inhibiting the overproduction of early response proinflammatory cytokines (IL- 6 and tumor necrosis factors alpha ) which are over expressed in COVID-19 and contributed to disease progression, poor outcomes, vascular hyperpermeability and multiorgan failure in patients infected with severe acute respiratory syndrome(SARS-CoV-2) and also, via blocking COVID-19 entry by inhibiting androgenic factors which induce transmembrane protease, serine 2 (TMPRSS2) expression, In addition to inhibiting of Angiotensin-converting enzyme 2(ACE2) ,AT1 protein and Ang II-mediated intracellular calcium release pathway which is responsible for SARS-CoV-2 cell fusion and entry as opposed to ACE inhibitors (ACEIs) or angiotensin II type-I receptor blockers (ARBs) that upregulate ACE-2 receptors which might increase the risk of infection and subsequent complications Moreover, another study demonstrated that isotretinoin is a potential inhibitor of papain like protease (PLpro) which is a protein expressed by SARS-CoV-2 RNA and considered one of the proteins that should be targeted in COVID-19 treatment. And also,more than one study reported that 13 cis Retinoic Acid induces CD4+CD25+FOXP3+ Regulatory T Cells which their absence during acute infection alters the ability of the host to limit tissue damage In addition, isotretinoin was reported to increase CD4 counts and markedly decrease viremia in HIV positive patients suffering from acne vulgaris and retinoic acid inducible gene-1 (RIG-1) expression. And also, another study reported that 13 Cis retinoic acid induced significant upregulation of toll-like receptor 3 resulting in an immune response to dsRNA intermediate which can be partially generated during CoV-2 replication . TLR3 sensitized by dsRNA and cascades of signaling pathways (IRFs and NFκB activation, respectively) are activated to produce type I IFNs. The production of type I IFNs is important to enhance the release of antiviral proteins for the protection of uninfected cells. Isotretinoin therapy has furthermore proven anti-inflammatory, anti-platelet and fibrinolytic activities. which may protect patients infected with covid-19 from widespread blood clots. From this point, the principal investigator expects that isotretinoin will be the Immunity passport" in the context of COVID-19 Keywords: COVID 2019 , Retinoic acid, Endosomal toll-like receptor 3,T Cells, IFN type1, AT1, ACE2,TMPRSS2,RIG-1.
