Halts the multiplication and spread of the virus by leveling up miRNAs from the hsa-miR-200 family, and hsa-miR-125b expression, leading to reduced ACE2 receptors’ level. Furthermore, hsa-miR-15b and hsa-miR-622 play a role as they bind to viral S proteins to hinder the infection. This evidence concerns the gene PROS1 and infection.
