Abstract

A neutrophil monolayer system was used to study the effects of uric acid on neutrophil-aggregate interactions important in rheumatoid inflammation. No effect on immunoglobulin G aggregate phagocytosis was seen, but hyperuricaemic levels of uric acid were associated with an enhancement of phagocytosis-induced release of the azurophilic granular enzyme beta-glucuronidase. A trinitrophenyl-coupled mononuclear leucocyte rheumatoid factor plaque-forming assay was utilised to study uric acid effects on polyclonal activation of immunocompetent cells. Low levels of uric acid enhanced and high levels suppressed this system. Hyperuricaemia may enhance some aspects of rheumatoid inflammation, while uric acid may modulate an important component of rheumatoid autoimmunity.

摘要

采用中性粒细胞单层系统研究尿酸对类风湿性炎症中重要的中性粒细胞聚集相互作用的影响。未观察到对免疫球蛋白G聚集物吞噬作用的影响，但高尿酸水平的尿酸与吞噬作用诱导的嗜天青颗粒酶β-葡萄糖醛酸酶释放增强有关。利用三硝基苯基偶联的单核白细胞类风湿因子斑块形成试验研究尿酸对免疫活性细胞多克隆激活的影响。低水平尿酸增强该系统，而高水平尿酸则抑制该系统。高尿酸血症可能会增强类风湿性炎症的某些方面，而尿酸可能会调节类风湿性自身免疫的一个重要组成部分。
