Description
技术领域
本发明涉及人类免疫缺陷病毒糖蛋白120gp120诱导神经病理痛药物用途发明领域,尤其是涉及亮蓝G可用于在制备降低人类免疫缺陷病毒糖蛋白120gp120诱导的神经病理痛的药物中的应用,其作用机理涉及抑制背根神经节嘌呤2X(P2X)7受体介导的痛觉信息传递。
背景技术
人类免疫缺陷病毒(human immunodeficiency virus,HIV)感染常可导致神经系统认知、感觉和行动功能障碍,引发各种神经系统疾病,严重时可危及生命。HIV感染并发周围神经病变的病人肢体远端出现感觉功能障碍,呈袜套式分布,足部最先疼痛,伴随着病情的进一步发展,患者肢体将会出现极度疼痛和功能障碍,导致行走功能丧失。HIV感染神经导致周围神经发生病理改变,而原发病变部位可能在背根神经节(dorsal root ganglia,DRG)。已证实在HIV病毒的表面,多种蛋白具有神经毒性,包括穗花状的结构外膜糖蛋白(glucoprotein120,gp120)。gp120暴露在HIV病毒表面,因其相对分子质量为120KD而得名,在病毒浸染宿主细胞的过程中发挥重要作用。体外实验模型和体内实验模型研究都证实它与HIV感染相关性末梢感觉多发性神经病的病理相关,gp120还能介导培养的Schwann细胞和DRG神经细胞凋亡。病毒通过包膜糖蛋白gp120识别并浸染宿主细胞,通过巨噬细胞和小胶质细胞产生炎性细胞因子和神经毒素,导致神经元受损,并阻碍神经递质的释放和运输。HIV包膜糖蛋白gp120可以直接兴奋初级感觉传入神经元,导致痛觉过敏。重组gp120鞘内注射或短暂置于坐骨神经膜上可增强动物的热痛敏和机械痛敏。
大多数疾病都伴随有疼痛,给人们造成极大痛苦,其治疗是世界难题之一。按疼痛时程不同,可将疼痛分为急性痛(生理性痛)和慢性痛(病理性痛)。神经病理性疼痛就属于慢性痛。神经病理性疼痛(neuropathic pain,NPP),简称神经痛,是由躯体感觉系统的损伤或疾病引起的疼痛,令人感觉不愉快。NPP常伴随感觉功能障碍,对非伤害性刺激产生痛觉过敏,这种痛觉有的为连续性的,有的是阵发性的。阵发性的疼痛感像被电击或刀割一样。周围神经损伤后,可能发生异常再生,神经元变得异常敏感,并自发地进行病理活动,对化学、冷、热和机械刺激高度敏感。NPP发病率较高,患者常感到疼痛难忍,常伴有睡眠障碍、精神萎靡、注意力分散、焦虑、抑郁、食欲减退,严重影响病人的生活质量。NPP发病的分子机理仍不清楚,治疗受限,诱发因素多种多样。HIV感染的神经病理痛并发症有自发痛和诱发痛。感觉神经病理改变是HIV并发外周神经病理性损伤的最常见形式,可影响30%的艾滋病感染的成人和儿童患者。HIV感染并发神经病理痛的发病率较高、发病机理尚不清楚、治疗极为困难,亟待解决。
Burnstock在1972年首次提出了“嘌呤能神经学说”,认为ATP可作为第一信使参与信息传递,调节组织细胞的生物生化代谢与生理活动。嘌呤信号转导(purinergicsignalling)受体分为P1和P2受体。腺苷及其类似物作用于P1受体;三磷酸腺苷(ATP)及其类似物作用于P2受体。根据受体的状态和功能的不同可将P2受体分为配体门控性离子通道型受体(P2X受体,包括P2X1-7)和G蛋白偶联型受体(P2Y受体,包括P2Y1、P2Y2、P2Y4、P2Y6、P2Y11、P2Y12、P2Y13、P2Y14、P2Y15)。P2X属于配体门控非选择性阳离子通道受体,ATP与其结合后,Na+、K+等阳离子可以通过。目前,随着基因敲除技术和P2X7受体选择性拮抗剂的问世,P2X7受体在一些神经病理性痛的作用越来越明确。
当受到外界损伤及伤害性剌激时,受损细胞、应激细胞以及感觉神经末梢释放的ATP大量增加,ATP在痛觉及相关伤害性信息传递中具有重要作用。研究显示P2X7受体参与炎症痛、NPP的发生。由ATP激活的P2X7受体在病毒急性感染的炎症反应调节过程中承担着重要角色。文献显示HIV包膜糖蛋白gp120损伤坐骨神经诱发NPP,上调背根神经节的炎性因子表达。因此,ATP、炎性因子等信号分子可能激活表达于DRG的P2X7受体,参与HIV感染并发NPP的痛觉形成和维持。HIV感染并发NPP的防治是个十分棘手的问题。目前尚不清楚DRG中P2X7受体在HIV感染并发的NPP中的作用。
本实验通过人类免疫缺陷病毒糖蛋白120诱导神经病理痛大鼠模型,观察P2X7受体特异性拮抗剂亮蓝G(brilliant blue G,BBG)处理后人类免疫缺陷病毒糖蛋白120诱导神经病理痛大鼠痛行为的变化,以及与介导神经病理痛的P2X7受体表达变化的关系,为亮蓝G用于人类免疫缺陷病毒糖蛋白120诱导神经病理痛的预防和治疗提供帮助。应用

7、新生大鼠原代培养。
3-5天内的新生SD大鼠苯巴比妥(50mg/kg)腹腔注射麻醉后,用大头针将四肢固定俯卧于泡沫手术台上,用75%酒精消毒皮肤,铺无菌手术巾。经背部正中切开皮肤,钝性分离脊柱两旁肌肉,充分暴露棘突和横突,从颈部椎管开口插入显微剪,交替在中线两侧将椎管平行剪开,用显微镊去除椎板暴露脊髓,解剖显微镜下可见两侧椎间孔内圆形透亮的脊神经节,显微镊轻轻推脊髓两侧以松动神经节,然后慢慢将脊髓从椎管中提出(神经节成串挂于脊髓两侧)转入装有5mL DMEM:F/12培养基的100mm培养皿中。在解剖显微镜下用镊子逐个分离摘取神经节。转移入加有0.25%胰蛋白酶和I型胶原酶的离心管中,37℃培养箱中消化20min。加入含有10%FBS的培养基终止胰蛋白酶的消化,离心,重悬,用吸管小心吹打,将其制成单细胞悬液,接种于用多聚氨酸包被处理的细胞培养皿中于37℃、5%CO2培养箱中进行培养。培养基成分为Neurobasal培养基、2%B27、50ng/ml神经生长因子、2mmol/L L-谷氨酰胺以及双抗。培养48h后大部分DRG已经贴壁,全量换液并加入5μmol/L阿糖胞苷以抑制非神经元细胞的增殖,96h后全量换液,此后每48h半量换液。做膜片钳实验前,神经元分别用含有或者不含200pmol/L HIV gp120处理24h。
8、电生理电流记录。

9、统计学方法。
应用SPSS统计软件对实验数据进行分析,结果以均数±标准差表示,各组之间差异性采用方差分析,组间比较采用LSD法,p<0.05表示有显著性差异,p<0.01为极显著差异。
二、结果。
(一)行为学结果。
各组大鼠造模中均未见肢体运动障碍和自残现象。造模前测定各组间机械缩足反射阈值的基础值差异无显著性(p>0.05)。
机械痛敏(MWT)测定结果。
Gp120大鼠神经病理痛模型的机械缩足反射潜伏期测定结果显示,在术后7天到14天,模型组与对照组相比,手术侧机械痛反应阈值明显降低(p<0.01)。模型+亮蓝G处理组与模型组相比,手术侧机械痛反应阈值明显升高(p<0.01)。(见图1)。
(二)实时定量-聚合酶链式反应(Real-time PCR)。
P2X7受体表达。
P2X7的Real-time PCR结果表明:gp120模型组DRG中P2X7受体mRNA表达水平较对照组明显增加(p<0.01),gp120模型+亮蓝G处理组较模型组明显降低(p<0.01)。(见图2)。
(三)蛋白印迹。
1、P2X7蛋白印迹结果。
P2X7蛋白印迹结果表明:gp120模型组DRG中P2X7受体表达水平较对照组明显增加(p<0.01);gp120模型组+亮蓝G处理组P2X7受体蛋白的表达低于模型组(p<0.01)(见图3)。
2、TNF-α蛋白印迹结果。
TNF-α蛋白印迹结果表明:gp120模型组DRG中TNF-α受体表达水平较对照组明显增加(p<0.01);gp120模型组+亮蓝G处理组P2X7受体蛋白的表达低于模型组(p<0.01)(见图4)。
3、IL-1β蛋白印迹结果。
IL-1β蛋白印迹结果表明:gp120模型组DRG中IL-1β受体表达水平较对照组明显增加(p<0.01);gp120模型组+亮蓝G处理组P2X7受体蛋白的表达低于模型组(p<0.01)(见图5)。
4、IL-10蛋白印迹结果。
IL-10蛋白印迹结果表明:gp120模型组DRG中IL-1β受体表达水平较对照组明显降低(p<0.01);gp120模型组+亮蓝G处理组P2X7受体蛋白的表达高于模型组(p<0.01)(见图6)。

(四)全细胞膜片钳记录结果。
在培养的新生大鼠DRG神经元细胞上进行实验,神经元细胞呈圆形或椭圆形,选用轮廓和形态清晰的中小细胞进行实验。Gp120模型组的BzATP激活电流明显大于对照组(p<0.01),亮蓝G对gp120模型组BzATP激活电流的抑制作用也较对照组明显(见图8)。
发明人研究发现注射亮蓝G后,HIV gp120模型组DRG中P2X7的表达降低,同时观察到注射亮蓝G后HIV gp120模型组大鼠的机械痛升高,表明亮蓝G可降低HIVgp120模型组神经病理大鼠的痛行为。亮蓝G处理后同时可下调HIV gp120模型组大鼠背根神经节P2X7受体的表达,降低细胞炎性因子—肿瘤坏死因子(TNF-α)和白细胞介素(IL-1β)的含量,增加抗细胞炎性因子—白细胞介素(IL-10)的含量,降低ERK1/2磷酸化水平。因此,亮蓝G可能通过减少TNF-α、IL-1β的释放、增加IL-10的释放、减少ERK1/2磷酸化水平、降低HIV gp120神经病理大鼠背根神经节P2X7受体的表达、抑制背根神经节P2X7受体介导的伤害性信息传递,减轻HIV gp120神经病理痛大鼠的痛行为。
