摘要
As a chronic systemic autoimmune disease,systemic lupus erythematosus(SLE)can influence multiple organs and systems.Although the pathological basis and risk factors for SLE have been extensively investigated,the exact pathogenesis of SLE remains to be explored.However,there is increasing evidence that T-cell−Bcell interactions promote the development of SLE,resulting in the generation of high-affinity antibodies[1].Tfh cells,a subgroup of T cells,can promote the formation of germinal centers,the maturation of B cells,and the differentiation of plasma cells[2].It has been found that multiple transcription factors(TFs)can regulate the generation of Tfh cells.For instance,B-cell lymphoma-6(BCL-6),an evolutionarily conserved zinc-finger protein,is an important positive transcription factor responsible for the differentiation and maturation of Tfh cells.In addition to maintaining the phenotype and GC response of Tfh cells,BCL-6 can also regulate the dynamics of T-cell−B-cell interactions and improve the efficiency of delivering help to B cells[3].
