We examined interleukin-2 (IL-2) activity in patients with Behçet's disease. T cells from all patients with Behçet's disease were able to produce normal levels of IL-2 in response to phytohemagglutinin; however, responsiveness to IL-2 was impaired in their concanavalin A-activated lymphoblasts. This defect was due to decreased numbers of cells bearing IL-2 receptors in patients with early active disease; in patients with chronic active or with inactive disease, there was a decrease in density of IL-2 receptors on T cells bearing these receptors. Unresponsiveness of T cells to IL-2 may thus contribute to immunologic aberrations in Behçet's disease.
我们检测了白塞病患者的白细胞介素-2(IL-2)活性。所有白塞病患者的T细胞对植物血凝素刺激均能产生正常水平的IL-2;然而,其伴刀豆球蛋白A激活的淋巴母细胞对IL-2的反应性受损。该缺陷是由于早期活动期疾病患者中携带IL-2受体的细胞数量减少;在慢性活动期或非活动期疾病患者中,携带这些受体的T细胞上IL-2受体的密度降低。因此,T细胞对IL-2无反应性可能导致白塞病的免疫异常。
