在许多由自身免疫或感染引起的慢性炎症性疾病中,B 细胞浸润皮肤。尽管有可能导致疾病,但与皮肤相关的 B 细胞的特征仍知之甚少。使用肉芽肿性皮肤炎症的绵羊模型,我们证明了炎症期间皮肤和皮肤引流传入淋巴液中的 B 细胞增加。令人惊讶的是,皮肤 B 细胞是一个异质群体,与淋巴结 B 细胞不同,具有更大的淋巴细胞以及共表达高水平 IgM 和 CD11b 的 B-1 样 B 细胞。与淋巴结 B 细胞相比,皮肤 B 细胞的 MHCII、CD1 和 CD80/86 表达增加,表明它们非常适合炎症部位的 T 细胞激活。此外,我们发现炎症期间皮肤 B 细胞和抗体分泌细胞的积累会增加局部抗体滴度,从而增强宿主防御和自身免疫。虽然皮肤 B 细胞表达典型的皮肤归巢受体,例如 E-选择素配体以及 α-4 和 β-1 整联蛋白,但它们对与 T 细胞归巢到皮肤相关的趋化因子受体配体没有反应。相反,皮肤 B 细胞会向皮肤表达的 CCR6 配体 CCL20 迁移。我们的数据支持一种模型,其中 B 细胞利用 CCR6-CCL20 通过皮肤进行再循环,在皮肤免疫和炎症中发挥新作用。
B cells infiltrate the skin in many chronic inflammatory diseases caused by autoimmunity or infection. Despite potential contribution to disease, skin-associated B cells remain poorly characterized. Using an ovine model of granulomatous skin inflammation, we demonstrate that B cells increase in the skin and skin-draining afferent lymph during inflammation. Surprisingly, skin B cells are a heterogeneous population that is distinct from lymph node B cells, with more large lymphocytes as well as B-1-like B cells that co-express high levels IgM and CD11b. Skin B cells have increased MHCII, CD1, and CD80/86 expression compared with lymph node B cells, suggesting that they are well-suited for T cell activation at the site of inflammation. Furthermore, we show that skin accumulation of B cells and antibody-secreting cells during inflammation increases local antibody titers, which could augment host defense and autoimmunity. While skin B cells express typical skin homing receptors such as E-selectin ligand and alpha-4 and beta-1 integrins, they are unresponsive to ligands for chemokine receptors associated with T cell homing into skin. Instead, skin B cells migrate toward the cutaneously expressed CCR6 ligand CCL20. Our data support a model in which B cells use CCR6-CCL20 to recirculate through the skin, fulfilling a novel role in skin immunity and inflammation.
