- 产品介绍
- background:
Cytomegalovirus is a member of the herpes virus group, which includes herpes simplex virus types 1 and 2, varicella zoster virus (which causes chicken pox), and Epstein Barr virus (which causes infectious mononucleosis). These viruses share a characteristic ability to remain dormant within the body over a long period. CMV viral genes are co-ordinately expressed in groups at various times after infection. Early viral proteins are expressed in the nucleus of infected cells within 3 to 24 hours of infection prior to the commencement of viral DNA replication. This is followed by expression of the early intermediate genes, which encode enzymes required for viral DNA replication. After 48 to 72 hours, a number of late viral antigens may be demonstrated in the nuclei and cytoplasm of infected cells. pp65 is a 65kD phosphorylated glycoprotein and is the most abundant of the late antigens.
Function:
Counteracts the host antiviral immune response by preventing IRF3 to enter the nucleus once activated and phosphorylated. Participates also in the transactivation of viral major imediate-early genes by recruiting host IFI16 to their promoters.
Subunit:
Interacts with host NCL/nucleolin. Interacts with host IFI16.
Subcellular Location:
Virion tegument (Potential). Host nucleus. Host cytoplasm. Note=As part of the incoming virion, pp65 is targeted to the nucleus immediately after infection. The newly synthesized pp65 is observed in the nucleus until some time after 48 hours postinfection. Thereafter, pp65 is probably exported and accumulates in the cytoplasm. Also found in dense bodies.
Post-translational modifications:
Phosphorylation may play a role in the localization of the protein.
Similarity:
Belongs to the herpesviridae pp65 family.

CMV又称为涎病毒,属于疱疹病毒亚科,是人类疱疹病毒组中最大的一种病毒。由分子量约为150X106的线状双股DNA所组成。其形最大由162个壳粒(capsomer),正20面体构成。有典型的疱疹病毒结构。形态与单纯疱疹病毒及水痘-带状疱疹病毒非常相似,不易区别。 CMV只能在人纤维母细胞的组织培养中增殖,而不能在其他动物细胞中生长,增殖非常缓慢,其复制周期为36-48小时,比单纯疱疹病毒复制周期8小时要长得多。初次分离需一个多月才能出现特殊的细胞;细胞变园,膨胀,细胞及核巨大化,核周围出现一轮“晕”的大型嗜酸性包涵体。在活体中的靶细胞主要是上皮细胞。人类CMV各株之间有广泛交叉反应。
CMV在20%乙醚中最多存活2小时。pH<5时,或置于56℃30分钟,或紫外线照射5分钟可被充分灭活。CMV的感染性对冻融或存于-20℃或-50℃均不稳定,10%的家用漂白粉可使其感染性明显降低。
CMV感染的特征时出现有典型的胞浆及核内包涵体的巨大细胞,故又名巨细胞病毒。它在人体组织中可形成肥大的细胞,引起巨细胞包涵体病。
巨细胞病毒感染可导致致畸
人巨细胞病毒是一种双链DNA病毒,是最大的动物病毒之一。人是人巨细胞病毒唯一可感染的对象。同其他病毒相比,由于人巨细胞病毒的毒力较弱,侵入机体后一般不会使器官和组织受到严重损伤,但是该病毒基因整合在受精卵细胞的相关基因后,则可阻止或影响后者的复制和表达,最后导致不可逆的形态和结构的异常。
巨细胞病毒主要在早孕3个月内感染致胎儿畸形,脑是巨细胞病毒最易侵袭的器官,胎儿脑组织中的神经元细胞、神经胶质细胞均可受侵犯。颅内钙盐沉着、脑软化、脑积水是人巨细胞病毒感染最常见的临床表现,其后遗症也以神经系统最为严重。最常见的是智力低下,其他如粗大运动异常,精神运动异常,感觉神经性耳聋,脉络膜视网膜炎等。虽然在听力和神经方面明显存在着高风险,甚至可能有后遗症,只有5%的被感染婴儿会在新生儿期就表现巨细胞病毒感染征象。而90%的先天性感染的胎儿出生时无任何临床症状。因此,加强监测,尽早诊断是预防巨细胞病毒感染致畸的重要措施。怀孕时初次感染巨细胞病毒的孕妇,其胎儿的感染率是30%,而被感染的孕妇在分娩时有40%可传染给胎儿。妊娠期,巨细胞病毒感染至今尚无特殊疗法,所以关键在预防。对早孕妇女,不仅可监测其抗体,还可用特殊方法监测其抗原,如果发现孕妇体内有巨细胞病毒活跃复制,应采取果断措施,终止妊娠,以避免畸形儿出生。此外,要提高人们的文化素质,讲究卫生,杜绝病毒感染的各种机会,并注意保持和增强人体免疫功能,这样就有可能防止或减少育龄妇女巨细胞病毒感染。
巨细胞包涵体病对小儿脑组织广泛损伤-智力障碍
巨细胞包涵体病是由于巨细胞病毒感染后,引起的全身多个器官损害并出现临床症状的疾病。若在出生时就有临床症状,则为宫内感染(先天感染),出生后数天或数周发病多为出生后感染。巨细胞病毒感染很广泛,是先天病毒感染的重要病原之一。巨细胞病毒感染可引起胎儿脑组织广泛损伤,是小儿智力低下的最主要原因。
巨细胞病毒感染较广泛,大多数人一生中不同时期均可获得感染。居住拥挤、经济条件差、卫生条件差的人易感染。女性较同龄男性感染率高。晚期孕妇宫颈排出巨细胞病毒者达28% ,是先天性巨细胞病毒感染的重要原因。母乳排毒者约13%~27%,且排毒时间长,易引起后天感染。
巨细胞病毒感染后,临床表现有多种类型。如为先天感染,出生后即有低体重,呼吸不规则,黄疸重,肝脏、脾脏肿大,抽搐,视力受损,肌肉瘫痪,智力低下等。如为后天感染,一般症状较轻,多表现为肝炎症状。
因此,育龄妇女怀孕前应做体检,如果发现有巨细胞病毒感染应抗病毒治疗,使血中巨细胞病毒抗体转阴,子宫颈分泌物检查巨细胞病毒为阴性方可受孕。
