干燥综合征 (SS) 涉及一种主要发生在唾液腺和泪腺的慢性进行性炎症,导致唾液和泪液水平下降,从而导致口干和干眼疾病。关于主要分泌白细胞介素 (IL)-17A 的 TH17 细胞群的开创性发现已被证明在越来越多的自身免疫性疾病(包括 SS)中发挥着重要作用。在本研究中,我们研究了 IL-17A 在 SS 发生和发病中的功能。通过逆行插管将表达 IL-17A 或 LacZ 的腺病毒血清型 5 (Ad5) 载体输注到 6 至 8 周龄或 15 至 17 周龄的 C57BL/6J 小鼠的唾液腺中。对小鼠进行了 SS 表型的表征。疾病特征表明,唾液腺接受 Ad5-IL17A 载体的 SS 非易感性 C57BL/6J 小鼠出现了类似 SS 的疾病特征,包括淋巴细胞病灶的出现、细胞因子水平增加、抗核抗体特征变化以及唾液流暂时丧失。 IL-17A 在 SS 非易感小鼠中诱导 SS 病理强烈表明,IL-17A 是唾液腺功能障碍中重要的炎症细胞因子。因此,局部抗IL17治疗可能有效预防腺体功能障碍。
Sjögren's syndrome (SS) involves a chronic, progressive inflammation primarily of the salivary and lacrimal glands leading to decreased levels of saliva and tears resulting in dry mouth and dry eye diseases. Seminal findings regarding TH17 cell populations that secrete predominantly interleukin (IL)-17A have been shown to play an important role in an increasing number of autoimmune diseases, including SS. In the present study, we investigated the function of IL-17A on the development and onset of SS. Adenovirus serotype 5 (Ad5) vectors expressing either IL-17A or LacZ were infused via retrograde cannulation into the salivary glands of C57BL/6J mice between 6 and 8 weeks of age or between 15 and 17 weeks of age. The mice were characterized for SS phenotypes. Disease profiling indicated that SS-non-susceptible C57BL/6J mice whose salivary glands received the Ad5-IL17A vector developed a SS-like disease profile, including the appearance of lymphocytic foci, increased cytokine levels, changes in antinuclear antibody profiles, and temporal loss of saliva flow. Induction of SS pathology by IL-17A in SS-non-susceptible mice strongly suggests that IL-17A is an important inflammatory cytokine in salivary gland dysfunction. Thus, localized anti-IL17 therapy may be effective in preventing glandular dysfunction.
