In SG epithelial cells, IL-17 inhibited acetylcholine-induced calcium movement and downregulated the expression of transient receptor potential canonical 1 via promoting mRNA stabilisation. Moreover, local IL-17 neutralisation in SG markedly attenuated hyposalivation and ameliorated tissue inflammation in ESS mice. These findings identify a novel function of IL-17 in driving salivary dysfunction during pSS development and may provide a new therapeutic strategy for targeting SG dysfunction in pSS patients.

Type I interferons are evolutionally conserved cytokines, with broad antimicrobial and immunoregulatory functions. Despite well-characterised role in spontaneous cancer immunosurveillance, the function of type I IFNs in cancer immunotherapy remains incompletely understood. We utilised genetic mouse models to explore the role of the type I IFN system in CD8 T-cell immunotherapy targeting the melanocytic lineage antigen gp100. The therapeutic efficacy of adoptively transferred T cells was found to depend on a functional type I IFN system in myeloid immune cells. Compromised type I IFN signalling in myeloid immune cells did not prevent expansion, tumor infiltration or effector function of melanoma-specific Pmel-1 CD8 T cells. However, melanomas growing in globally (Ifnar1 ) or conditionally (Ifnar1 ) type I IFN system-deficient mice displayed increased myeloid infiltration, hypoxia and melanoma cell dedifferentiation. Mechanistically,
