Viral replication of SARS-CoV-2 could be self-limitative – The role of the renin-angiotensin system on COVID-19 pathophysiology.
Currently, the world is suffering with one of the biggest pandemics of recent history. Caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the coronavirus disease 2019 (COVID-19) is provoking devastating consequences on economic and social fields throughout all continents. Therefore, pathophysiological knowledge about COVID-19 is imperative for better planning of preventive measures, diagnosis, and therapeutics of the disease. Based on previous studies, this work proposes new hypothesis related to the role of the renin-angiotensin system on the pathophysiology of COVID-19, and its purpose is to enrich the discussion and to offer alternative ways for experimental and clinical studies aiming at the formulation of new diagnosis and/or treatment methods.
