Estonian researchers make a breakthrough in the development of the human papillomavirus drugs

Researchers of the University of Tartu and Icosagen Cell Factory have introduced the new cellular monitoring system for evaluating the growth of the human papillomavirus (HPV) and the effect of drugs; the new drug screening system could considerably speed up the development of a new HPV drug. 

Being the most common sexually transmitted infection globally, HPV is typically spread by sustained direct skin-to-skin contact with vaginal and anal sex being the most widespread methods.

New method

“Almost all people get a papillomavirus infection at some point in their life but the majority of infections pass relatively harmlessly and in many people the symptoms never appear,” Mart Toots, a doctoral researcher whose dissertation studied the life-threatening or cancerous types of the virus, said in an article published in PLOS Pathogens journal.

However, some infections are more serious. There are more than 200 subtypes of human papillomaviruses and they may cause illnesses ranging from warts to throat and cervical cancer. HPV-caused illnesses are treated using a wide variety of methods with varying success, but no specific cure for the infection exists so far.

To aid development for an efficient cure, Toots and his colleagues from the University of Tartu and Icosagen, one of the leading biotechnology companies in Estonia, created a new method that enables the identification of potentially effective drugs and drug targets. Their method takes into account the full HPV genome, as well as all three stages of the viral life cycle that occur during the infection.

To develop the new system, researchers genetically engineered HPV genomes by adding bioluminescent proteins that allow easy monitoring of viral growth at any stage of life cycle. This enables to quickly test whether a potential drug has an effect on the virus or not – and thereby speed up the development of potential drug candidates.

Identifying new drugs

The researchers said the new system would allow identifying several new drugs, which could be used effectively for the elimination of skin-related low-risk and high-risk infections, including those that could otherwise lead to malignant tumours.

So far, the method has been used to screen more than 1,600 chemical compounds, several of which were identified as blocking the growth of some high-risk subtypes of HPV.

This research was financed by the Institute of Technology of the University of Tartu, Icosagen, and the European Regional Development Fund through Enterprise Estonia.

  1. Learning that you have HUMAN PAPILLOMAVIRUS(HPV) can be one of the most difficult experiences you go through in life. You may feel scared, sad or even angry – this is OK, and a completely natural part of coping with something that can be life changing.

    It will probably take a while for the news to sink in.

    I remember spending so much money buying drugs like Gardasil, Imiquimod (Aldara), and Podofilox(Condylox) from hospitals hoping that i will be cured, but all to no avail. I contacted so many doctors and they prescribe Antiviral, which they indeed tried their best but was unable to provide for me a possible cure, luckily a good friend of mine told me to a herbal doctor website, (Dr. Vikraft Sambo).

    At first i never wanted to contact him because i have been fraud by lots of online scam. After much chat and enquiry with the doctor, i decide to take a leap of faith because i have nothing to loose.

    To my greatest surprise, Dr. Vikraft Sambo NEVER DEMANDED FOR AN UPFRONT FEE when i contacted him. All he did was to give me a Herbal Medicine and guidelines on how i am to take them. I followed all procedures as instructed, and after 11 days i went back for a check up, and i was tested NEGATIVE of HUMAN PAPILLOMAVIRUS(HPV).

    I just want to encourage all individuals out there living with HUMAN PAPILLOMAVIRUS(HPV), That there is still a huge chance that you can get well again.

    You can contact Dr. Vikraft Sambo using his email (vikraft.sambo@gmail.com). or visit his website below for more details;

    Doctor Vikraft Sambo will never ask you for an upfront fee payment.

    BEWARE OF FRAUDSTERS ONLINE.
