Interferon Type I (IFN-I) might be involved in disease pathology; however, evidence is limited. This study explores a systemic IFN-I signature and expression of IFN-I markers in GCA and PMR patients. Treatment naive GCA and PMR patients, and PMR patients with glucocorticoid treatment were included. Patients suspected of but not diagnosed with GCA were used as controls. Five relevant IFN-I-stimulated genes were identified in literature, and relative expression levels were determined using quantitative reverse transcription polymerase chain reaction (RT-qPCR) in peripheral blood mononuclear cells. An IFN-I score was generated. Serum levels of IFN-I induced C-X-C motif chemokine 10 (CXCL10) and Galectin-9 were determined by multiplex immunoassay. There were no differences in IFN-I scores between the groups. An IFN-I signature was observed in 0/9 controls, 2/11 GCA patients, 4/20 treatment naive PMR patients, and 2/10 PMR patients with treatment. Serum CXCL10 and Galectin-9 were not increased in GCA or PMR patients compared to control patients. Treated PMR patients had lower CXCL10 levels [423.2 pg/ml (375.1-491.1)] compared to treatment naive PMR patients [641.8 pg/ml (552.8-830.6)]. An IFN-I signature does not distinguish GCA and PMR patients from controls. Also, IFN-I-induced serum markers are not upregulated in GCA and PMR patients.

Transcriptome sequencing data of patients with psoriasis were obtained, in which differentially expressed genes were assessed by principal component analysis. A diagnostic model was developed using random forest algorithm and validated by receiver operating characteristic (ROC) curves. Subsequently, we performed consensus clustering to calculate angiogenesis-associated molecular subtypes of psoriasis. Additionally, a correlation analysis was conducted between ARGs and immune cell infiltration. Finally, validation of potential ARG genes was performed by quantitative real-time PCR (qRT-PCR). We identified 29 differentially expressed ARGs, including 13 increased and 16 decreased. Ten ARGs, CXCL8, ANG, EGF, HTATIP2, ANGPTL4, TNFSF12, RHOB, PML, FOXO4, and EMCN were subsequently sifted by the diagnostic model based on a random forest algorithm. Analysis of the ROC curve (area under the curve [AUC] = 1.0) indicated high diagnostic performance in internal validation. The correlation analysis suggested that CXCL8 has a high positive correlation with neutrophil (R =0.8, P < 0.0001) and interleukins pathway (R = 0.79, P < 0.0001). Furthermore, two ARG-mediated subtypes were obtained, indicating potential heterogeneity. Finally, the qRT-PCR demonstrated that the mRNA expression levels of CXCL8 and ANGPTL4 were elevated in psoriasis patients, with a reduced expression of EMCN observed.

Since homeostatic NET-forming neutrophils [NET+Ns] have beneficial roles in defense against pathogens, their distinction from pro-injury [NET+N] subtypes is important, especially if they are to be therapeutically targeted. Having identified circulating, pro-injury DEspR+CD11b+[NET+Ns] in patients with neutrophilic secondary tissue injury, we determined whether DEspR+[NET+Ns] are present in rheumatoid arthritis (RA) flares. Whole blood samples of patients with RA flares on maintenance therapy (n = 6) were analyzed by flow cytometry (FCM) and immunofluorescence cytology followed by semi-automated quantitative confocal microscopy (qIFC). We assessed clinical parameters, levels of neutrophils and [NET+Ns], and plasma S100A8/A9. qIFC detected circulating DEspR+CD11b+neutrophils and [NET+Ns] in RA-flare patients but not healthy controls. DEspR+[NET+Ns] were positive for citrullinated histone H3 (citH3+), extruded DNA, decondensed but recognizable polymorphic nuclei, and [NET+N] doublet interactions in mostly non-ruptured NET-forming neutrophils. Circulating DNA+/DEspR+/CD11b+/citH3+microvesicles (netMVs) were observed. FCM detected increased %DEspR+CD11b+neutrophils and DEspR+ cell-cell doublets whose levels trended with DAS28 scores, as did plasma S100A8/A9 levels. This study identifies circulating DEspR+/CD11b+neutrophils and [NET+Ns] in RA-flare patients on maintenance therapy. Detection of circulating DEspR+citH3+[NET+Ns] and netMVs indicate a systemic neutrophilic source of citH3-antigen concordant with multi-joint RA pathogenesis. Increased S100A8/A9 alarmin levels are associated with cell injury and released upon NET-formation. As a ligand for TLR4, S100A8/A9 forms a positive feedback loop for TLR4-induced DEspR+neutrophils.
