Wang et al. further identified differential vimentin expression across CRS subgroups [controls, CRSsNP, non-eosinophilic CRSwNP (ECRSwNP), and ECRSwNP], with the highest vimentin positivity in ECRSwNP epithelium, suggesting EMT is particularly prominent in eosinophilic CRSwNP (77). Here, VIM is linked to chronic rhinosinusitis without nasal polyps.
