ABSTRACT
Currently, there are no reliable biomarkers for identifying COVID-19 patients and no definite therapeutics to control this deadly disease. MicroRNAs (miRNA) have been explored in several human diseases for their potential role as biomarkers and their therapeutic potential. However, there is very little information available about the roles of miRNAs in COVID-19 infection. This chapter outlines the recent updates and developments of miRNAs in COVID-19 such as miRNAs as potential biomarkers for COVID-19, the molecular basis of miRNAs in COVID-19 infection, and the use of miRNAs as therapeutics targets for COVID-19. While a few potential miRNAs have been researched for the aforementioned reasons, more research is needed to determine the roles of individual miRNAs in COVID-19 infection. © 2023 Elsevier Inc.
