New HPV info?????

I had types a question about HPV in Yahoo Answers and I just received this info...not so sure I am so confident about the body "keeping it in check" anymore...
Not sure where she gotten this info, but it seems/sounds factual.

UAB Researchers Make Breakthrough Discovery of HPV ReplicationPosted on March 15, 2004 at 4:00 p.m.

UAB Researchers have discovered the mechanism used by a common virus to replicate and remain in the human body for decades. Human papillomavirus (HPV), a family of over 100-related viruses, are responsible for a variety of medical conditions, ranging from benign hand or foot warts to genital warts, cervical cancer and recurrent respiratory papillomatosis, a potentially fatal disease in children.

In an article published in the Proceedings of the National Academy of Sciences in March, the research team reports that a viral replication protein known as E2 binds the circular viral DNA to cell structures called spindle fibers that are present in a cell when it divides, a process known as mitosis. In mitosis, a single cell divides in two, creating two genetically identical daughter cells. By latching onto the spindle fibers of the cell as it divides, HPV DNA also divides and replicates itself in each of the new daughter cells where it can continue to replicate and persist indefinitely.

“In effect, HPV is able to mimic our own chromosomes, behaving as a sort of ‘mini-chromosome’, independently replicating and keeping pace as the cellular chromosomes replicate and the cell divides,” says Tom Broker, PhD, professor of biochemistry and molecular genetics and co-author of the paper. “This allows the virus to remain in our bodies indefinitely, with the potential of causing serious disease years, even decades, after first exposure.”

Broker says that virtually all humans carry at least one type of HPV for much of their lives, usually transmitted to the external skin very early in life or to the internal mucosal lining later during sexual contact. For most people, the virus persists at low levels without causing obvious disease, and the body’s immune system keeps it in check.

However, in some people, the virus can become activated and cause lesions, particularly if the infected tissue is repeatedly injured, or following periods of emotional or physical stress, during pregnancy, as a result of immunosuppressive therapy for immune disorders or organ transplantation, as a outcome of progressing HIV/AIDS, and even as a consequence of aging.

“This is a major breakthrough in our quest to find ways to treat the myriad conditions associated with HPV,” says Louise Chow, PhD, professor of biochemistry and molecular genetics and co-author of the paper. “This improves our understanding of the mechanisms the virus uses to reproduce. We now have new molecular targets to aim at for antiviral drug discovery.”

HPV’s special mechanism for attaching itself to the mitotic spindles and getting pulled into the daughter cells has not been observed with other families of viruses, according to Chow.

There are about 15,000 new cases of cervical or penile cancer attributed to HPV each year in the US, and nearly 5000 deaths. Worldwide, 600,000 cases occur annually, especially in developing countries without advanced medical diagnostic methods such as Papanicolaou smear screening, which can detect the activation of HPV early enough for aggressive treatment to be successful.

HPV infection in the throat and respiratory tract, laryngeal papillomatosis, can cause recurrent respiratory papillomatosis in children, who are usually infected at birth from contact with HPV-caused genital warts present in the mother. There are an estimated 2,000 cases per year in the United States

This research was funded by grants from the United States Public Health Service and the National Cancer Institute, one of the National Institutes of Health. Tom Broker is the President of the International Papillomavirus Society. More information on HPV and associated disease can be found at the society’s web site at www.IPVSoc.org

I rarely believe anything confidently I read on Yahoo answers, particularly if it's not sourced appropriately.  But this article doesn't say anything that much different than the information you can find here.  It claims those who are pregnant, have autoimmune difficult, have HIV/AIDS or other severe health conditions may have recurrence troubles- which is what most basic HPV info will tell you.

So, I guess I just dont understand why mine is back?? ( I am not 100% positive that it is, but I cant imagine what else it would be) I am just having a hard time with this.... I am rarely sick, eat  (for the most part) healthy. Quit smoking. I guess, life's not fair. I am healthy for the most part :o)  I shouldn't complain!

this is a most mysterious newly discovered common virus with so many un-answered questions...my gynecologist said in 10 years they will probably find a cure for it!we can hope eh?:))))
