We also transfected the CoV2‐miR‐O7a.2 mimic at a lower concentration to mimic the copy number per cell as observed on the infection (~2,000 copies/cell) (Fig EV5E), and we found that at this concentration as well CoV2‐miR‐O7a.2 is able to downregulate both BATF2 and LAMP3 mRNA (Fig EV5F). This evidence concerns the gene BATF2 and infection.
