Our results showed that HspB5 is weakly expressed in HNEC of healthy subjects (1.57 ± 0.22 ng/μg of proteins) but more strongly expressed in HNEC derived from nasal polyps from patients with CF (4 ± 0.45 ng/μg of proteins) or with CRS (3.74 ± 1.31 ng/μg of proteins) (Figure 1A). Here, CRYAB is linked to nasal cavity polyp.
