TSLP and asthma: The expression of TSLP observed in biopsy samples was found to be significantly elevated in the polyp tissue of all patient subgroups in comparison with HCs (CRSwNP without asthma) (72.41 ± 53.64, p = 0.048); asthmatics with CRSwNP (104.49 ± 76.78, p = 0.009); and N-ERD (121.23 ± 145.03, p = 0.009), (Table 4).
