免疫系统激活涉及亨廷顿病 (HD) 的发病机制,这一过程的生物标志物可能与研究该疾病和表征对特定干预措施的治疗反应有关。我们的目的是研究 HD 患者脑脊液中的炎症细胞因子和小胶质细胞标记物。检测了 23 名突变携带者和 14 名健康对照者的脑脊液 TNF-α、IL-1β、IL-6、IL-8、YKL-40、壳三糖苷酶、总 tau 蛋白和神经丝轻链 (NFL)。 CSF TNF-α 和 IL-1β 低于检测限。突变携带者比对照组具有更高的 YKL-40 (p = 0.003)、壳三糖苷酶 (p = 0.015) 和 IL-6 (p = 0.041)。调整年龄后,YKL-40 与疾病阶段 (p = 0.007)、UHDRS 总功能能力评分 (r = -0.46,p = 0.016) 和 UHDRS 总运动评分 (r = 0.59,p = 4.5*10−4) 显着相关。经过进一步研究,脑脊液中的 YKL-40 水平可能会成为 HD 某些方面的生物标志物。需要进一步的调查来支持我们的探索性发现。
Immune system activation is involved in Huntington’s disease (HD) pathogenesis and biomarkers for this process could be relevant to study the disease and characterise the therapeutic response to specific interventions. We aimed to study inflammatory cytokines and microglial markers in the CSF of HD patients. CSF TNF-α, IL-1β, IL-6, IL-8, YKL-40, chitotriosidase, total tau and neurofilament light chain (NFL) from 23 mutation carriers and 14 healthy controls were assayed. CSF TNF-α and IL-1β were below the limit of detection. Mutation carriers had higher YKL-40 (p = 0.003), chitotriosidase (p = 0.015) and IL-6 (p = 0.041) than controls. YKL-40 significantly correlated with disease stage (p = 0.007), UHDRS total functional capacity score (r = -0.46, p = 0.016), and UHDRS total motor score (r = 0.59, p = 4.5*10−4) after adjustment for age. YKL-40 levels in CSF may, after further study, come to have a role as biomarkers for some aspects of HD. Further investigation is needed to support our exploratory findings.
