Deep brain stimulation of the subthalamic nucleus (DBS-STN) is an effective treatment for advanced motor symptoms of Parkinson's disease (PD). Recently, a connection between the limbic part of the STN and side effects of DBS-STN has been increasingly recognized. Animal studies have shown that DBS-STN influences behavior and provokes neurochemical changes in regions of the limbic system. Some of these regions, which are activated during DBS-STN, are involved in neuroimmunomodulation. The therapeutic effects of DBS-STN in PD treatment are clear, but the influence of DBS-STN on peripheral immunity has not been reported so far. In this study, we examined the effects of unilateral DBS-STN applied in male Wistar rats with 6-hydroxydopamine PD model (DBS-6OHDA) and rats without nigral dopamine depletion (DBS) on corticosterone (CORT) plasma concentration, blood natural killer cell cytotoxicity (NKCC), leukocyte numbers, lymphocyte population and apoptosis numbers, plasma interferon gamma (IFN-γ), interleukin 6 (IL-6), and tumor necrosis factor (TNF-α) concentration. The same peripheral immune parameters we measured also in non-stimulated rats with PD model (6OHDA). We observed peripheral immunity changes related to PD model. The NKCC and percentage of T cytotoxic lymphocytes were enhanced, while the level of lymphocyte apoptosis was down regulated in 6OHDA and DBS-6OHDA groups. After DBS-STN (DBS-6OHDA and DBS groups), the plasma CORT and TNF-α were elevated, the number of NK cells and percentage of apoptosis were increased, while the number of B lymphocytes was decreased. We also found, changes in plasma IFN-γ and IL-6 levels in all the groups. These results suggest potential peripheral immunomodulative effects of DBS-STN in the rat model of PD. However, further studies are necessary to explain these findings and their clinical implication.

丘脑底核深部脑刺激术（DBS-STN）是治疗帕金森病（PD）晚期运动症状的一种有效方法。最近，人们越来越认识到丘脑底核的边缘部分与DBS-STN的副作用之间存在联系。动物研究表明，DBS-STN会影响行为，并引发边缘系统区域的神经化学变化。其中一些在DBS-STN过程中被激活的区域参与神经免疫调节。DBS-STN在PD治疗中的疗效是明确的，但迄今为止，DBS-STN对外周免疫的影响尚未见报道。在本研究中，我们检测了对雄性Wistar大鼠应用单侧DBS-STN，其中包括6-羟基多巴胺帕金森病模型大鼠（DBS-6OHDA）和未发生黑质多巴胺耗竭的大鼠（DBS），观察其对皮质酮（CORT）血浆浓度、血液自然杀伤细胞细胞毒性（NKCC）、白细胞数量、淋巴细胞亚群及凋亡数量、血浆干扰素γ（IFN-γ）、白细胞介素6（IL-6）和肿瘤坏死因子（TNF-α）浓度的影响。我们还对未接受刺激的帕金森病模型大鼠（6OHDA）测量了相同的外周免疫参数。我们观察到与帕金森病模型相关的外周免疫变化。在6OHDA和DBS-6OHDA组中，NKCC及细胞毒性T淋巴细胞百分比升高，而淋巴细胞凋亡水平下调。在进行DBS-STN后（DBS-6OHDA和DBS组），血浆CORT和TNF-α升高，NK细胞数量及凋亡百分比增加，而B淋巴细胞数量减少。我们还发现，所有组的血浆IFN-γ和IL-6水平均有变化。这些结果表明，DBS-STN在帕金森病大鼠模型中具有潜在的外周免疫调节作用。然而，需要进一步研究来解释这些发现及其临床意义。图形摘要：丘脑底核深部脑刺激对帕金森病大鼠模型外周免疫的影响
