However, the expression of CX3CR1 and GZMB in B cells has not been clarified, and their clinical significance in systemic lupus erythematosus (SLE) remains unclear. This study aimed to clarify the changes and clinical significance of peripheral blood B cells expressing GZMB and\/or CX3CR1 in SLE. Peripheral blood was collected from 39 patients with SLE and 48 healthy controls. We found that GZMB and CX3CR1 expression varied in different B-cell subsets, with plasmablasts possessing the highest positive percentages, consistent with bioinformatics prediction. GZMB+ and CX3CR1+ percentages in circulating B cells and plasmablasts were increased in patients with SLE. CX3CR1 was upregulated on B cells after in vitro stimulation. Notch intracellular domain expression was significantly decreased in plasmablasts of patients with SLE, and CX3CR1 in plasmablasts was downregulated with the addition of JAG1. In conclusion, GZMB and CX3CR1 were increased in B cells and in plasmablasts of patients with SLE and CX3CR1 was negatively regulated by Notch signal in plasmablasts, which may be involved in SLE pathogenesis.<\/jats:p>","DOI":"10.1093\/jleuko\/qiae127","type":"journal-article","created":{"date-parts":[[2024,6,5]],"date-time":"2024-06-05T01:21:31Z","timestamp":1717550491000},"page":"1061-1071","source":"Crossref","is-referenced-by-count":0,"title":["Upregulation
