1. Innate immunity and HPV: friends or foes
Most human papillomavirus infections are readily cleared by the host immune response. However, in some individuals, human papillomavirus can establish a persistent infection. The persistence of high-risk human papillomavirus infection is the major risk factor for cervical cancer development. These viruses have developed mechanisms to evade the host immune sy

2. Bonafide, type-specific human papillomavirus persistence among HIV-positive pregnant women: predictive value for cytological abnormalities, a longitudinal cohort study
This study investigated the rate of human papillomavirus (HPV) persistence, associated risk factors, and predictors of cytological alteration outcomes in a cohort of human immunodeficiency virus-infected pregnant women over an 18-month period. HPV was typed through L1 gene sequencing in cervical smears collected during gestation and at 12 months after delive

3. Characteristics of co-infections by HCV and HBV among Brazilian patients infected by HIV-1 and/or HTLV-1
BACKGROUND: The human retroviruses HIV-1 and HTLV-1 share the routes of infection with hepatitis viruses B and C. Co-infection by these agents are a common event, but we have scarce knowledge on co-infection by two or more of these agents. OBJECTIVE: To evaluate the characteristics and risk factors for co-infections by HBV and HCV in patients infected by HIV

4. Human Papillomavirus (HPV) infection in HIV positive and negative men: analysis of HPV persistence and histological findings in clinical and sub-clinical lesions / Infecção pelo Papilomavírus Humano (HPV) em homens soropositivos e negativos ao HIV: persistência e relação histológica de lesões clínicas e subclínicas
BACKGROUND: Co-infection with HPV and HIV modifies its natural history and increases the risk of warts and neoplasia development in the anogenital tract. Cohort studies to address HPV infection in the penis are scarce, mainly in HIV infected individuals. METHODS: A longitudinal study, non-probabilistic, was conducted with 144 men of 18 to 70 years old includ

5. O papilomavirus humano e lesões do colo uterino
Analisamos uma coorte de mulheres no sul do Brasil, com objetivo de identificar associações epidemiológicas para persistência e cura da infecção pelo HPV e realizamos uma metanálise para determinar a acurácia da telomerase nas lesões precursoras do câncer cervical. Métodos: O estudo de coorte foi iniciado em fevereiro de 2003. Foram coletados esp�

6. Th1 Cytokine Patterns in Cervical Human Papillomavirus Infection
The host’s immune response to cervical human papillomavirus (HPV) infection is poorly understood. In a longitudinal cohort of women with cervical HPV infections, defined by PCR-based HPV DNA testing, we used exfoliated cervical cells and reverse transcription-PCR to examine the cervical mucosal mRNA expression of cytokines involved in regulating cell-

7. Vaccination of Rabbits with an Adenovirus Vector Expressing the Papillomavirus E2 Protein Leads to Clearance of Papillomas and Infection
Cervical cancer arises from lesions caused by infection with high-risk types of human papillomavirus (HPV). Therefore, vaccination against HPV could prevent carcinogenesis by preventing HPV infection or inducing lesion regression. HPV E2 protein is an attractive candidate for vaccine development because it is required for papilloma formation, is involved in

8. Managing women with human papillomavirus changes in cervical cytology.
Of 86 women with cervical cytological evidence of human papillomavirus (HPV) infection who underwent colposcopy, 55 yielded histological confirmation of HPV infection and 17 of them had cervical intraepithelial neoplasia (CIN). Of 51 women followed up six months after cryotherapy of their cervical lesions, 46 showed no evidence of HPV infection in their cerv

9. Altered Expression of TAP-1 and Major Histocompatibility Complex Class I in Laryngeal Papillomatosis: Correlation of TAP-1 with Disease
Recurrent respiratory papillomatosis (RRP) is an insidious disease caused by human papillomavirus (HPV) infection. It is characterized by a variable clinical course that can include frequent disease recurrence, significant morbidity, and occasional mortality. The mechanisms responsible for the variability in the clinical course and the persistence of latent
