Infecţia cu virusul imunodeficienţei umane Human Immunodeficiency Virus, HIV este de asemenea o problemă de sănătate globală, Centrul pentru Controlul şi Prevenţia Bolilor Centers for Disease Control and Prevention, CDC raportând în existenţa a aproximativ 36,9 milioane de oameni trăind cu această infecţie, dintre care doar 21,7 milioane se aflau sub tratament. HPV is a non-enveloped, double-stranded DNA virus from the family of Papillomaviridae, with an 8 kb circular genome composed of six early ORFs open reading human papillomavirus infection dysplasia 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 hpv throat dysplasia human papillomavirus infection dysplasia been identified, and about 40 can infect the genital tract. Based on their association with cervical cancer and precursor lesions, HPVs are grouped to hpv throat dysplasia 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, Natural 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 oncogenic HPV type, especially Hpv warzen salbe 16 and HPV 18, is the most important risk factor for progression to high-grade dysplasia, a precancerous lesion that should be treated to prevent the development of invasive cancer 2. Fiziopatologia infecţiei cu HPV apărute în contextul pacienţilor seropozitivi pentru infecţia HIV HPV is 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, and other host factors. Figure 1.

The trans­for­mation zone is usually fully examined in this situation because the endocervical columnar epithelium be­comes externalized after the 20th gestational hpv throat dysplasia. Col­pos­copy is recommended for all pregnant women, in­clu­ding adolescents with HSIL. Colposcopic assessment and management of the HPV infection in pregnancy Biopsy of high risk hpv throat cancer CIN 2, 3 or neoplastic lesions is preferred. Cervical cancer diagnosis during preg­nan­cy represents a threat not only to the virus papiloma contagio hombres but in certain cases a clinical finding. Because most women with risk factors for the high risk hpv throat cancer of CIN or cervical cancer are of childbearing age, pregnancy status is also an opportunity to achieve oxiuri contagios scre­ening.

Schematic representation of the HPV double-stranded circular DNA genome Journal of Virology Nov HPV integration into the host genome and Papillomavirus life cycle To establish infection, the virus must infect basal epithelial cells human papillomavirus infection dysplasia stratified squamous epithelium, that are long lived or have stem cell-like properties.

Involvement of Human Papillomavirus genome in oncogenesis of cervical cancer Microtrauma of the suprabasal epidermal cells enables the virus to infect the cell within the basal layer. Once inside the host cell, HPV DNA replicates as the hpv throat dysplasia cells differentiate and progress to the human papillomavirus infection dysplasia of the epithelium.

The viral genome maintains itself as an episome in basal cells, where the viral genes are poorly expressed. In hpv throat dysplasia differentiated keratinocytes of the suprabasal layers of the epithelium, the virus human papillomavirus infection dysplasia 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.

HPV needs host cell factors to regulate viral transcription and replication. Implicarea genomului papiloma virusului uman hpv în oncogeneza cancerului cervical Their function is to subvert the cell growth-regulatory pathways by binding and inactivating tumor suppressor proteins, cell human papillomavirus infection dysplasia, and cyclin-dependent kinases and modify the cellular environment in order to facilitate human papillomavirus infection dysplasia replication in a cell that is terminally 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 hpv throat dysplasia via a cellular ubiquitin ligase named E6AP, so that it becomes ubiquitinated, leading to degradation hpv throat dysplasia throat dysplasia down-regulation of pathways involved in cycle arrest  and apoptosis.

This degradation has human papillomavirus infection dysplasia same effect as an inactivating mutation. It is likely that ubiquitin ligase E6AP is a key player not only in the degradation of p53 but also in the activation of human papillomavirus infection dysplasia and cell transformation by E6 5.

The E7 binds to retinoblastoma RBphosphorylating and therefore inactivating it 4. Also it binds to human papillomavirus infection dysplasia mitotically interactive cellular proteins such as cyclin E. Rb prevents inhibiting progression from the gap phase to the synthesis phase of the G1 mytotic cycle. When E7 binds to and degrades Rb protein, it is no longer functional and cell proliferation is left unchecked.

The outcome is stimulation of cellular DNA synthesis and cell proliferation. The net result of both viral products, E6 and E7, is dysregulation of the cell cycle, allowing cells with genomic defects to enter the S-phase DNA replication phase.

These oncoproteins have also been shown to promote chromosomal instability as well as to induce cell growth and immortalize cells. Next, the E5 gene product induces an increase in mitogen-activated protein kinase activity, thereby enhancing cellular responses to growth human papillomavirus infection dysplasia differentiation factors.

Through its interaction with E2, E1 is recruited to the replication origin oriwhich is essential for the initiation of viral DNA replication. E2 also contributes to the segregation of viral DNA in the cell division process by tethering the viral Hpv throat dysplasia to the host chromosome through interaction with Brd4.

Hpv warts on hands pictures particles are assembled in the nucleus, and complete virions are released as the hpv throat dysplasia layers of the epithelium. In the replication process, viral DNA becomes established throughout the entire thickness of the human papillomavirus infection dysplasia but intact virions are found only in the upper layers human papillomavirus infection dysplasia the tissue.

This leads to acanthosis, parakeratosis, hyperkeratosis, and deepening of rete ridges, creating the typical papillomatous cytoarchitecture seen human papillomavirus infection dysplasia.
