系统性红斑狼疮(SLE)是一种病因不明的自身免疫性疾病,会影响多个组织和器官。三氧化二砷 (ATO) 已用于狼疮易感小鼠,对免疫异常具有调节作用。四硫化二砷(As4S4)是一种中药,对急性早幼粒细胞白血病有效,且副作用比ATO轻。在本研究中,进行了一项初步研究,以研究 As4S4 对易患狼疮的 BXSB 小鼠的影响和机制。 As4S4 治疗观察到脾脏单核细胞增多症的改善 (p<0.05) 和血清白细胞介素 6 (IL-6) 的降低 (p=0.0277)。 As4S4 治疗的小鼠表现出皮肤、肝脏和肾脏疾病的改善,且副作用轻微。组织学分析表明,As4S4 抑制肾脏和肝脏中的免疫复合物沉积、系膜增殖和炎症细胞浸润。我们的研究支持 As4S4 选择性抑制 BXSB 小鼠的皮肤狼疮和肾炎,并且可能是 SLE 的潜在治疗方法。
Systemic lupus erythematosus (SLE) is an autoimmune disease of uncertain etiology that affects multiple tissues and organs. Arsenic trioxide (ATO) has been used in lupus-prone mice with a regulatory effect on immune abnormality. Tetra-arsenic tetra-sulfide (As4S4), a traditional Chinese medicine, is effective on acute promyelocytic leukemia with mild side effects than ATO. In this study, a pilot study was performed to investigate the effects and the mechanism of As4S4 on the lupus-prone BXSB mice. Improvement of monocytosis (p < 0.05) in spleen and decreased serum interleukin-6 (IL-6) (p = 0.0277) were observed with As4S4 treatment. As4S4-treated mice exhibited amelioration of skin, liver and renal disease with mild side effects. Histological analysis revealed that As4S4 suppressed immune complex deposition, mesangial proliferation and inflammatory cell infiltration in kidney and liver. Our study support that As4S4 selectively suppresses cutaneous lupus and nephritis in BXSB mice and might be a potential treatment for SLE.
