show Abstracthide AbstractPyogenic arthritis, pyoderma gangrenosum and acne (PAPA) syndrome is characterized by flares of sterile arthritis with neutrophil infiltrate and the overproduction of Interleukin (IL)-1ß. The purpose of this study was to elucidate the potential role of neutrophil subsets and neutrophil extracellular traps (NETs) in the pathogenesis of PAPA. The transcriptome of PAPA normal-dense neutrophils, autologous LDGs, and healthy control normal-dense neutrophils was characterized using RNASeq. The transcriptome of a PAPA skin biopsy and a healthy control skin sample was elucidated using RNASeq. Overall design: This dataset includes a total of 5 individual samples. This study sought to characterize PAPA normal-dense neutrophils, autologous LDGs, and healthy control normal-dense neutrophils and determine their transcriptomic profiles. We also wanted to characterize the transcriptomic profile of PAPA skin compared to a healthy control skin.
