Differentially expressed genes (DEGs) were intersected with PRGs to identify pyroptosis\u2010related DEGs (PRDEGs). Functional enrichment was assessed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). Key genes were identified using the least absolute shrinkage and selection operator (LASSO) and support vector machine (SVM) analyses. A diagnostic model was constructed using logistic regression. mRNA\u2013microRNA (miRNA) and mRNA\u2013transcription factor (TF) interaction networks were constructed. Immune cell infiltration (ICI) was analyzed using cell\u2010type identification by estimating relative subsets of RNA transcripts (CIBERSORTs) and single\u2010sample gene set enrichment analysis (ssGSEA). Experimental validation was performed in nonobese diabetic (NOD)\/ShiLtj mice using reverse transcription quantitative polymerase chain reaction (RT\u2010qPCR), western blotting, and immunofluorescence and was further validated using immunofluorescence in pSS patient samples.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 489 DEGs were identified, of which 22 were pyroptosis\u2010related.
