目的
2
探讨牛磺熊去氧胆酸(TUDCA)对脊髓损伤后神经源性异位骨化(NHO)的抑制作用及其可能机制。
方法
2
选用SPF级雄性C57BL/6小鼠建立NHO模型,小鼠随机分为3组:假手术组(仅椎板切除术)、NHO模型组(脊髓损伤+心脏毒素肌肉注射)和TUDCA治疗组(NHO模型基础上每日灌胃TUDCA 200 mg/kg,连续4周)。通过小动物CT(micro-CT)、H&E染色定量评估异位骨化面积及成熟度;采用流式细胞术定量M2巨噬细胞白细胞介素(IL)-1β分泌水平。体外培养RAW264.7巨噬细胞,分为对照组、TNFα组和TNFα+TUDCA组(TUDCA 200 μmol/L),检测其极化标志物CD206表达水平;分为对照组、TUDCA 200 μmol/L组和TUDCA 400 μmol/L组,检测巨噬细胞IL-1β的分泌水平。
结果
2
与NHO组对比,TUDCA治疗组小鼠的骨量显著减少(12.69±1.13
vs
. 7.647±1.19,
P
=0.003);与TNFα组相比,qPCR结果显示TNFα+TUDCA组 M2巨噬细胞标志物CD206的表达显著上调(0.55±0.019,1.11±0.023,
P
<0.001);与对照组相比,ELISA结果显示TUDCA刺激巨噬细胞可显著上调IL-1β的分泌水平(404.7±24.38
vs
. 652.8±32.61,
P
=0.003 7); TUDCA喂养可上调肌肉局部巨噬细胞分泌IL-1β并抑制异位骨化形成。
结论
2
TUDCA可能通过诱导M2巨噬细胞极化并上调IL-1β分泌参与抑制NHO形成,从而减轻脊髓损伤后神经源性异位骨化的发生发展,为拓展TUDCA在脊髓损伤并发症治疗中的应用提供了实验依据。
Objective
2
To investigate the inhibitory effect of tauroursodeoxycholic acid (TUDCA) on neurogenic heterotopic ossification (NHO) after spinal cord injury and its potential mechanism.
Methods
2
SPF-grade male C57BL/6 mice were used to establish an NHO model. The mice were randomly divided into three groups: sham operation group (laminectomy only), NHO model group (spinal cord injury + intramuscular injection of cardiotoxin), and TUDCA treatment group (NHO model + daily intragastric administration of TUDCA at 200 mg/kg for 4 consecutive weeks). The area and maturity of heterotopic ossification were quantitatively assessed by micro-computed tomography(micro-CT) and hematoxylin-eosin(H
&
E) staining. Flow cytometry was used to quantify the interleukin(IL)-1β secretion level of M2 macrophages. RAW264.7 macrophages were cultured
in vitro
and divided into control, tumor necrosis factor(TNF)α, and TNFα+TUDCA (200 μmol/L) groups to detect the expression level of the polarization marker CD206. Additionally, macrophages were divided into control, TUDCA 200 μmol/L, and TUDCA 400 μmol/L groups to assess the IL-1β secretion level.
Results
2
Compared with the NHO group, the bone volume in the TUDCA-treated group was significantly reduced (12.69±1.13
vs
. 7.647±1.19,
P
=0.003). Compared with the TNFα group, qPCR results showed that the expression of the M2 macrophage marker CD206 was significantly upregulated in the TNFα+TUDCA group (0.55±0.019,1.11±0.023,
P
<0.001). Compared with the control group, ELISA results showed that TUDCA stimulation of macrophages significantly upregulated IL-1β secretion (404.7±24.38
vs
. 652.8±32.61,
P
=0.003 7). TUDCA administration upregulated IL-1β secretion by local muscle macrophages and inhibited heterotopic ossification formation.
Conclusions
2
TUDCA might participate in inhibiting NHO formation by inducing M2 macrophage polarization and upregulating IL-1β secretion, thereby alleviating the development and progression of neurogenic heterotopic ossification after spinal cord injury. This finding provides experimental evidence for expanding the application of TUDCA in the treatment of complications following spinal cord injury.
