天疱疮是一种针对皮肤和/或粘膜的器官特异性自身免疫性疾病。我们前期研究发现,寻常型天疱疮(pemphigus vulgaris, PV)病变浸润淋巴细胞体外培养后产生抗粘胶蛋白(Dsg) 1/3抗体。在这项研究中,我们发现弥漫性异位淋巴样结构(ELSs)通常存在于PV和天疱疮的病变中。值得注意的是,天疱疮病变中含有成中心细胞、浆母细胞和浆细胞,它们再现了B细胞分化的不同阶段。天疱疮病变中分化相关转录因子slimp -1、IRF4、bcl -6 mRNA表达水平升高。此外,B细胞受体库分析显示病变B细胞克隆扩增。病变B细胞可能在病变、淋巴结和外周血中循环。天疱疮病变中多种趋化因子mRNA表达水平升高,病变B细胞趋化因子受体表达水平升高。总之,这些结果表明天疱疮病变中的ELSs可能作为一个生态位,支持原位B细胞分化和克隆扩增。
Pemphigus is an organ-specific autoimmune disease that targets skin and/or mucous membranes. Our previous study showed that infiltrating lymphocytes in pemphigus vulgaris (PV) lesions produce anti-desmoglein (Dsg) 1/3 antibodies after in vitro culture. In this study, we found diffuse ectopic lymphoid-like structures (ELSs) commonly present in the lesions of both PV and pemphigus foliaceus. Notably, pemphigus lesions contained centroblasts, plasmablasts, and plasma cells, which recapitulated the different stages of B cell differentiation. Elevated mRNA expression levels of the differentiation-related transcription factorsBLIMP-1,IRF4,andBCL-6were observed in pemphigus lesions. Moreover, B cell receptor repertoire analysis revealed the clonal expansion of the lesional B cells. Lesional B cells might recirculate among lesions, lymph nodes, and peripheral blood. Increased mRNA expression levels of multiple chemokines in pemphigus lesions and elevated expression levels of chemokine receptors on lesional B cells were also observed. Collectively, these results show that the ELSs in pemphigus lesions might act as a niche, supporting in situ B cell differentiation and clonal expansion.
