On a worldwide scale, the outbreak of the Severe Acute Respiratory Syndrome Coronavirus
2 (SARS-CoV-2) has led to extensive damage to the health system as well as the global economy.
Hitherto, there has been no approved drug or vaccine for this disease. Therefore, the use of general antiviral
drugs is at the first line of treatment, though complicated with limited effectiveness and systemic
side effects. Given the pathophysiology of the disease, researchers have proposed various strategies not
only to find a more specific therapeutic way but also to reduce the side effects. One strategy to accomplish
these goals is to use CRISPR/Cas13 system. Recently, a group of scientists has used the
CRISPR/Cas13 system, which is highly effective in eliminating the genome of RNA viruses. Due to
the RNA nature of the coronavirus genome, it seems that this system can be effective against the disease.
The main challenge regarding the application of this system is to deliver it to the target cells efficiently.
To solve this challenge, it seems that using virosomes with protein S on their membrane surface
can be helpful. Studies have shown that protein S interacts with its specific receptor in target cells
named Angiotensin-Converting Enzyme 2 (ACE2). Here, we propose if CRISPR/Cas13 gene constructs
reach the infected cells efficiently using a virosomal delivery system, the virus genome will be
cleaved and inactivated. Considering the pathophysiology of the disease, an important step to implement
this hypothesis is to embed protein S on the membrane surface of virosomes to facilitate the delivery
of gene constructs to the target cells.
