ABSTRACT
Introduction
The novel coronavirus (CoV) disease 2019 (COVID-19) is a viral infection that causes severe acute respiratory syndrome (SARS). It is believed that early reports of COVID-19 cases were noticed in December 2019 and soon after it became a global public health emergency. It is advised that COVID-19 transmits through human to human contact and in most cases, it remains asymptomatic. Several approaches are being utilized to control the outbreak of this fatal viral disease. microRNAs (miRNAs) are known signature therapeutic tool for the viral diseases; they are small non-coding RNAs that target the mRNAs to inhibit their post-transcriptional expression, therefore, impeding their functions, can serve as watchdogs or micromanagers in the cells.
Areas covered
This review work delineated COVID-19 and its association with SARS and Middle East respiratory syndrome (MERS), the possible role of miRNAs in the pathogenesis of COVID-19, and therapeutic potential of miRNAs and their effective delivery to treat COVID-19.
Expert opinion
This review highlighted the importance of various miRNAs and their potential role in fighting with this pandemic as therapeutic molecules utilizing nanotechnology.
Article highlights
The novel coronavirus disease 2019 (COVID-19) is caused due to SARS-CoV-2 infection which has been declared a pandemic.
The importance of miRNAs in the pathogenesis of this viral disease is summarized.
Currently, there is no approved treatment or vaccine for COVID-19 and miRNAs can become a potential therapeutic tool.
This work delineates the overall idea of developing nanoformulation(s) of the SARS-CoV-2-related miRNAs.
Multifaceted targeting approaches are required for miRNA nanotherapy for effectively tackling SARS-CoV-2.
The nanoparticles-based miRNAs could also be used in the form of nano-vaccines for the prevention from SARS-CoV-2.
