J Endod:沉默C1减弱牙髓疾病中的炎症和牙槽骨吸收

2019-06-05 lishiting MedSci原创

牙髓疾病是全球慢性感染性疾病中流行性最高的一种,在牙髓感染和发炎时发生,导致根周骨损伤、严重疼痛以及牙齿缺失。尽管有许多研究试图研发有效的治疗方案以减缓骨侵蚀和牙髓疾病相关的炎症,但是目前还是迫切需要行之有效的疗法。

牙髓疾病是全球慢性感染性疾病中流行性最高的一种,在牙髓感染和发炎时发生,导致根周骨损伤、严重疼痛以及牙齿缺失。尽管有许多研究试图研发有效的治疗方案以减缓骨侵蚀和牙髓疾病相关的炎症,但是目前还是迫切需要行之有效的疗法。在这篇研究中,作者采用基因疗法,通过重组腺相关病毒(AAV)介导的Atp6v1c1敲除技术靶向小鼠牙髓疾病模型的尖周骨吸收和炎症反应。结果显示,Atp6v1c1敲除通过损伤破骨细胞活性可以在减少70%骨吸收的同时,通过减少T细胞在根尖损伤处75%的浸润抑制炎症,并且保护牙周膜因炎症造成的破坏。值得注意的是,AAV介导的Atp6v1c1敲除基因疗法可以显著减弱尖周组织由于细菌感染引起的促炎症因子表达,包括肿瘤坏死因子α、白细胞介素1α、6、12和17水平。实时定量聚合酶链式反应结果显示,Atp6v1c1敲除可以减弱尖周组织破骨细胞特异性功能基因(ie, Ctsk)的表达。结论:尖周组织中AAV介导的Atp6v1c1敲除通过调节toll-like受体信号减缓牙髓疾病的进程,防止骨侵蚀以及减缓牙槽骨和牙周膜的炎症反应,表明靶向Atp6v1c1可以加速全新疗法的设计以减轻牙髓疾病的

SCI TRANSL MED:成骨不全症基因重大发现

Joeng等人研究了成骨细胞中的Wnt1信号,并发现了Wnt1缺陷小鼠中可以有效改善骨骼质量降低的药物作用靶点。研究人员采用了被称作“摇动小鼠”(swaying mouse)作为实验材料,这种小鼠本身就带有Wnt1突变,再通过骨特异性Cre-Lox系统进行有条件的Wnt1敲除和过表达。Wnt1在晚期成骨细胞和骨细胞中的缺失会导致自发性骨折,成骨细胞活性降低,并导致骨质量下降。相比之下,体内/体外试

Sci Rep:STEAP2敲除能够减少前列腺癌细胞的入侵能力

与正常前列腺比较,前列腺-2的六次跨膜上皮抗原(STEAP2)表达在前列腺癌中增加,表明了STEAP2也许能够促进前列腺癌的恶化。最近,有研究人员进行了旨在阐明STEAP2在前列腺致瘤过程中的功能作用情况和评估将其敲除后是否能够减少前列腺癌细胞侵入能力的研究。研究人员将STEAP2 siRNA转化进入PC3和LNCaP细胞系中,并且分析了增殖、迁移、入侵和基因表达情况。研究人员根据格林森得分情况,

Stroke:短暂局灶性脑缺血后IL - 4基因敲除小鼠的脑损伤加重

背景和目的卒中可通过激活引起损伤的炎症反应导致脑损伤。假说认为抗炎细胞因子白细胞介素4(IL - 4)可减少IL - 4基因敲除(KO)的成年雄性小鼠卒中后损伤,我们对其进行了检验。 方法制作IL – 4敲除小鼠及野生型小鼠短暂性大脑中动脉阻塞模型。通过氯化三苯四唑染色法评估了梗死体积的预后,神经评分和自发活动评估了行为结果的预后以及免疫染色和体视学计数评估了细胞应答的预后。 结果与野生型小
