The IL‐1 family member IL‐38 (IL1F10) suppresses inflammatory and autoimmune conditions. Here, we report that plasma concentrations of IL‐38 in 288 healthy Europeans correlate positively with circulating memory B cells and plasmablasts. IL‐38 correlated negatively with age (p = 0.02) and was stable in 48 subjects for 1 year. In comparison with primary keratinocytes, IL1F10 expression in CD19+ B cells from PBMC was lower, whereas cell‐associated IL‐38 expression was comparable. In vitro, IL‐38 is released from CD19+ B cells after stimulation with rituximab. Intravenous LPS in humans failed to induce circulating IL‐38, compared to 100‐fold induction of IL‐6 and IL‐1 receptor antagonist. In a cohort of 296 subjects with body mass index > 27 at high risk for cardiovascular disease, IL‐38 plasma concentrations were significantly lower than in healthy subjects (p < 0.0001), and lowest in those with metabolic syndrome (p < 0.05). IL‐38 also correlated inversely with high sensitivity C‐reactive protein (p < 0.01), IL‐6, IL‐1Ra, and leptin (p < 0.05). We conclude that a relative deficiency of the B cell product IL‐38 is associated with increased systemic inflammation in aging, cardiovascular and metabolic disease, and is consistent with IL‐38 as an anti‐inflammatory cytokine.

B 细胞细胞因子白细胞介素 38 浓度降低与超重受试者的心血管疾病风险相关

IL-1 家族成员 IL-38 (IL1F10) 抑制炎症和自身免疫性疾病。在这里,我们报告了 288 名健康欧洲人的血浆 IL-38 浓度与循环记忆 B 细胞和浆母细胞呈正相关。IL-38 与年龄呈负相关 ( p = 0.02),并且在 48 名受试者中稳定 1 年。与原代角质形成细胞相比,来自 PBMC 的CD19 + B 细胞中的IL1F10表达较低,而细胞相关的 IL-38 表达相当。在体外,IL-38 从 CD19 +用利妥昔单抗刺激后的 B 细胞。与 IL-6 和 IL-1 受体拮抗剂的 100 倍诱导相比,人体静脉注射 LPS 未能诱导循环 IL-38。在 296 名体重指数 > 27 的心血管疾病高危受试者的队列中,IL-38 血浆浓度显着低于健康受试者 ( p < 0.0001),而在代谢综合征患者中最低 ( p < 0.05)。IL-38 还与高敏感性 C 反应蛋白 ( p < 0.01)、IL-6、IL-1Ra 和瘦素 ( p< 0.05)。我们得出结论,B 细胞产物 IL-38 的相对缺乏与衰老、心血管和代谢疾病中全身炎症的增加有关,并且与作为抗炎细胞因子的 IL-38 一致。
