Résumé en anglais

Purpose of review Aberrations in the innate and in the adaptive arms of the immune system play both important roles in the initiation and progression of systemic lupus erythematosus (SLE). The aim of this study was to provide an update on the most recent findings on the cellular pathogenesis of SLE. Our overview focused particularly on results obtained over the last 18 months. Recent findings Recent observations have provided an improved understanding of the importance of low-density granulocytes, a highly proinflammatory subset of neutrophils. We also highlighted in this work recent descriptions of the various cellular sources associated with the interferon signature. In addition, novel contributions have also developed our understanding of the potential importance of extrafollicular T-B-cell interactions in SLE pathogenesis. Finally, the role of recently described B and T-cell subsets, that is, atypical memory B cells, T-peripheral helper cells, and Th10 T cells, were also reviewed. Summary Recent findings in the cellular pathogenesis of SLE give a deeper comprehension of previously described mechanisms which drive SLE pathogenesis and shed light on novel players in immune dysregulation that could help to identify potential therapeutic targets.< Réduire
