Hpv high low risk types
Înțelesul "HPV" în dicționarul Engleză The virus infects basal epithelial cells of stratified squamous epithelium. HPV E6 and E7 oncoproteins are the critical molecules in the process of malignant tumour formation.
Hpv high risk genotype
Interacting with various cellular proteins, E6 and E7 influence fundamental cellular functions like cell cycle regulation, telomere maintenance, susceptibility to apoptosis, intercellular adhesion and regulation of immune responses. High-risk E6 and E7 bind to p53 and pRb and inactivate their functions with dysregulation of the hpv high low risk types cycle.
Uncontrolled cell proliferation leads to increased risk of genetic instability. Usually, it takes decades for cancer to develop. This review presents the main mechanisms hpv high risk common HPV genome in the carcinogenesis of the uterine cervix.
Virusul infectează epiteliile bazale, celule de epiteliu scuamos stratificat. Proteinele celulare E6 și E7 influențează fundamental funcțiile celulare, cum ar fi hpv high risk common ciclului celular, întreținerea telomerilor, susceptibilitatea la apoptoză, adeziunea intercelulară și reglarea răspunsurilor imune.
E6 și E7 cu grad ridicat de risc hpv high risk common leagă la p53 și PRB și inactivează funcțiile lor cu dereglarea ciclului celular. Proliferarea necontrolată a celulelor conduce la un risc crescut de instabilitate genetică.
De obicei, este nevoie de zeci de ani pentru a dezvolta un cancer.

Although the majority of infections cause no symptoms and are self-limited, persistent infection with high-risk types of HPV is the most important risk factor for cervical cancer precursors and invasive cervical cancer. The presence of HPV in They are also responsible for others genital neoplasias like vaginal, vulvar, anal, and penian.
HPV is hpv high low risk types non-enveloped, double-stranded DNA virus from the family of Papillomaviridae, with an 8 kb circular genome composed of six early ORFs open reading frames with role in viral transcription and replication E1, E2, E4, E5, E6, E7two late ORFs L1,2-capsid proteins and a non-coding long controlled region LCR that contains a variety of cis elements, which regulate viral replication and gene expression.
More than HPV types have been identified, and about 40 can infect the genital tract.

Based on their association with cervical cancer and precursor lesions, HPVs are grouped to high-risk 16, 18, 31, 33, 34, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, 73, 82 and low-risk HPV types 6, 11, 42, 43, 44, 54, 61, 70, 72, Hpv high low risk types history Most genital HPV infections are benign, subclinical, and self-limited, and a high proportion of infections associated with low-grade cervical dysplasias also regress spontaneously 1.
By contrast, persistent cervical infection infection detected more than once in an interval of 6 months or longer with an hpv high risk common HPV type, especially HPV 16 and HPV 18, is the most cancerul rectal definitie risk factor for progression to high-grade dysplasia, a precancerous lesion that should be treated to prevent the development of invasive cancer 2.
HPV hpv high low risk types a necessary but not a sufficient condition for the development of cervical cancer. Cofactors associated with cervical cancer include: cigarette smoking, increased parity, increased age, other sexually transmitted infections, immune suppression, long-term oral contraceptive use, hpv high risk common other host factors.

Once inside hpv high risk common host cell, HPV DNA replicates as the basal cells differentiate and progress to the surface of the epithelium. The viral genome maintains itself as an episome in basal cells, where the viral genes are poorly expressed. In the differentiated keratinocytes of the suprabasal layers of the epithelium, the virus switches to a rolling-circle mode of DNA replication, amplifies its DNA to high copy number, synthesizes capsid proteins, and causes viral assembly to occur 3.
Involvement of Human Papillomavirus genome in oncogenesis of cervical cancer HPV needs host cell factors hpv high risk common regulate viral transcription and replication. Their function is to subvert the cell growth-regulatory pathways by binding and inactivating tumor suppressor proteins, cell cyclins, and cyclin-dependent kinases and modify the cellular environment in order to facilitate viral replication in a cell that is hpv high risk common differentiated and has exited the cell cycle 4.

Cell growth is regulated by two cellular proteins: the tumor suppressor protein, p53, and the retinoblastoma gene product, pRB. Unlike in many other cancers, the p53 in cervical cancer is usually wild type and is not mutated. E6 binds to p53 via a cellular ubiquitin ligase named E6AP, so that it becomes ubiquitinated, leading to degradation and down-regulation of pathways involved in cycle arrest hpv high risk common apoptosis.
This degradation has the same effect as an inactivating hpv high low risk types. It is likely that ubiquitin ligase E6AP is a key player not only in the degradation of p53 but also in the activation of telomerase and cell transformation by E6 5.
The E7 binds to retinoblastoma RBphosphorylating and therefore inactivating it 4.
