Enhanced glycogen metabolism supports the survival and proliferation of HPV-infected keratinocytes in condylomata acuminata

Condylomata acuminata (CA) is caused by HPV infections of keratinocytes and is a common sexually transmitted disease. The main clinical feature and risk of CA is the high recurrence of genital warts formed by infected keratinocytes. Metabolic reprogramming of most types of mammalian cells including keratinocytes can provide energy and intermediates essential for their survival. Here we report that HPV infection develops a hypoxic microenvironment in CA warts, inducing the accumulation of glycogen and increased glycogen metabolism in the infected keratinocytes in a HIF-1 α dependent pathway.

Ismagilov, Xu Han, Dongmei Lai, Feng ShenAbstractHuman papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide, and persistent HPV infection can cause warts and even cancer. Nucleic acid analysis of HPV viral DNA can be very informative for the diagnosis and monitoring of HPV. Digital nucleic acid analysis, such as digital PCR and digital isothermal amplification, can provide sensitive detection and precise quantification of ...

Human papillomavirus (HPV) is the most common sexually transmitted virus. The high-risk HPV types (i.e., HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59) are considered to be the main etiological agents of genital tract cancers, such as cervical, vulvar, vaginal, penile, and anal cancers, and of a subset of head and neck cancers. Three prophylactic HPV vaccines are available that are bivalent (vs. HPV16, 18), tetravalent (vs. HPV6, 11, 16, 18), and non-avalent (vs. HPV6, 11, 16, 18, 31, 33,45, 52, 58). All of these vaccines are based on recombinant DNA technology, and they are prepared from the purified L1 protein that s...

Authors: Ma B, Yuan J, Chen S, Huang K, Wang Q, Ma J, Lin R, Zhang L, Zhou Y, Wang T, Walton SF, Pan X, Chen G, Wang Y, Ni G, Liu X Abstract Genital warts, which are one of the most common sexually transmitted diseases (STDs), result from persistent infection with human papillomavirus (HPV), especially subtypes 6 or 11. Topical application of 5% imiquimod cream is currently recommended as a first-line treatment choice for genital warts, but the clearance and patient compliance rates remain less than sufficient. In the current study, we developed a temperature-sensitive gel that contains the host-defense peptides ca...

Abstract HPV is still the most common sexually transmitted infection, leading to the onset of many disorders while causing an increase in direct and indirect health costs. High Risk (HR) HPV is the primary cause of invasive cervical cancer and contributes significantly to the development of anogenital and oropharyngeal cancers. The introduction of universal HPV vaccination has led to a significant reduction in vaccine-targeted HPV infections, cross-protective genotypes, precancerous lesions and anogenital warts. Despite the several limitations of HPV vaccination programs, including vaccine type specificity, differ...

Background Studies in countries with high human papillomavirus (HPV) vaccination coverage have demonstrated marked reductions in anogenital wart (AGW) incidence. Our goal was to assess the impact of HPV vaccination in a population with suboptimal coverage by comparing AGW incidence trends in the years before and after vaccine introduction. Methods We conducted a retrospective analysis of AGW incidence trends using an ecologic study design among 11- through 39-year-olds enrolled at Kaiser Permanente Northwest. We defined incidence as the proportion of persons who had a new AGW diagnosis for each calendar year in the pr...

umban Human papillomaviruses (HPVs) are the most common sexually transmitted infections worldwide. Ninety percent of infected individuals clear the infection within two years; however, in the remaining 10% of infected individuals, the infection(s) persists and ultimately leads to cancers (anogenital cancers and head and neck cancers) and genital warts. Fortunately, three prophylactic vaccines have been approved to protect against HPV infections. The most recent HPV vaccine, Gardasil-9 (a nonavalent vaccine), protects against seven HPV types associated with ~90% of cervical cancer and against two HPV types associated wi...

This is a public health success story. A landmark report on the effectiveness of the quadrivalent human papillomavirus vaccine (4vHP) in the U.S. is now a matter of medical record. Human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the U.S., with nearly 80 million people infected with some type of HPV at some point in their lives [1]. About 14 million Americans, including teens, become infected each year [2]. HPV causes genital warts and is associated with an estimated 33,700 newly diagnosed cancers every year in the U.S.
