Assessment of the total expression of IL-17, IL-23 and receptors of IL-17, IL-23 in MSGs of patients with pSS, probable preclinical pSS, and nonautoimmune sicca syndrome and comparison of the total expression of IL-17, IL-23 and receptors of IL-17, IL-23 between three groups showed significant differences (P < 0.05) (Tables 2 and 3). Here, IL17A is linked to peeling skin syndrome.
