Researchers may be on the verge of exploiting the vulnerabilities of a virus that causes cervical cancer, thanks to a newly developed technique that enables scientists to mass-produce human papillomavirus HPV in the laboratory. HPV, which exists in more than forms, is the most prevalent sexually transmitted infection. Transmission of HPV can also occur non-sexually.

At least 50 dp of sexually active men and women will acquire genital HPV infection at some point in their lives. By age 50, at least 80 percent of women will have acquired genital HPV infection. We couldnt pursue a number of experimental approaches because of the small amounts of virus available. Although the infection is usually harmless, cauee types of HPV are responsible for nearly all cases of cervical cancer, and other types contribute to about a quarter of head and neck cancers and some skin cancers.

A more common, less virulent form of the virus causes genital warts. Do hpv warts cause cervical cancer the new technique scientists can quickly produce a thousand do hpv warts cause cervical cancer more infectious virus per culture dish than they could using conventional methods. Researchers are hopeful that this advance could lead to new antiviral drugs and to vaccines that would trigger the immune system to attack at an earlier stage in the virus's life cycle to stop HPV before it can replicate.

The illustration shows a view of the molecular surface of the atomic model of papillomavirus generated by HHMI investigator Stephen C. Harrison and colleagues. The primary obstacle to producing HPV in the laboratory has been that in the early stage of its infective cycle, the virus lurks in undifferentiated basal epithelial skin cells, said Ahlquist. Once there, it remains in a diffuse form at low levels, limiting its visibility to the immune system.

Only cervicao the epithelial cells begin differentiating does the virus emerge as distinct, infective viral particles, called virions. Thus, czuse Ahlquist, infectious HPV virus particles could only be obtained by laboriously differentiating cultured cells into artificial skin. This process takes weeks, and produces small amounts of virions, which permitted only limited study of the virus, said Ahlquist.

Two discoveries made it possible to develop a mass-production technique for the virus, said Ahlquist. Researchers had long known that the HPV capsid proteins, which were necessary for virion formation, could self-assemble. Also, said Ahlquist, John Schiller and his colleagues at the National Institutes of Health recently found that by introducing the genes for these self-assembling capsid proteins into cells along with smaller pieces of target DNA, the target genes could be packaged into viral like particles.

Based on these findings, Ahlquist and his colleagues developed a technique by which they could introduce the full HPV genome along with the genes for HPV capsid proteins into human cells and manipulate them to produce active, infectious viral particles. The resulting technique enables the scientists to produce over a thousand times more infectious virus per culture dish and takes only two days, he said.

Importantly, said Ahlquist, the system successfully produces multiple types xancer HPV. Do hpv warts cause cervical cancer researchers plan to use their production technique to study the early process of infection and to search for vulnerabilities in that do hpv warts cause cervical cancer, said Ahlquist. Ahlquist also said that the production technique could offer a way to screen for HPV antiviral drugs and could lead to enhanced vaccines that consist of live attenuated virus.

It is estimated that one in every women in developing countries will have cervical cancer before the age of The bivalent and quadrivalent HPV vaccines have proven to be safe, minimally reactogenic, and highly immunogenic. If not detected and treated at this early stage, when cure is virtually assured, the precancerous lesions can later become cancers.
