To refine analyses regarding tissue destruction and viral load, immunofluorescence data were generated using MUC5AC (mucus and mucus-producing cells, orange), acetylated tubulin (ciliated cells, red), Hoechst stain (nuclei, blue) and SARS-CoV-2 anti-N mAb (virus, green) (Fig. 1d) following infection with WT- (not shown) or Omicron BA.5 (Fig. 1d in absence or presence of 1% P80 natural essence. The gene discussed is MUC5AC; the disease is infection.
