NR4A1 and infection: We furthermore detected a significant increase in NR4A1 expression from 3 to 5 days post infection (Figure 5e) and a slight increase in FOSB expression at day 4 after SARS‐CoV‐2 infection, while no effects on FOS expression were observed (Figure 5e), suggesting a delayed response to SARS‐CoV‐2.
