In December 2019, a novel infectious disease, caused by Severe Acute Respiratory Syndrome-coronavirus 2 (SARS-CoV-2), was identified in Wuhan, China, now declared as a pandemic. The Renin-Angiotensin system (RAS) and angiotensin-converting enzyme 2 (ACE2) have drawn special attention, as ACE2 acts as a receptor for SARS-CoV2. No specific therapy against SARS-COV2 has been invented yet. There is a constant need towards understanding of the underlying pathophysiology to aid the pharmacological

... earch. We have looked at the current evidence on the relationship between SARS-COV-2 and RAS and ACE2. Articles in English language published between 1 st January 2003 and 15 th June 2020 were searched using keywords and MeSH (Medical Subject Heading). We used Google Scholar and Pubmed as search engines. Conclusion: Bats serve as primary reservoir for SARS-CoV2, but its intermediate host has not been identified yet. 'Hot spots' on ACE2, serve as receptors for SARS-COV2. Imbalance in the activity of ACE/ACE2 is an important contribution towards the pathogenesis of coronavirus related diseases. ACE2 also has protective role and recombinant ACE2 has been shown to improve lung injury and it is a potential therapeutic agent.
