Now, if the DNA is altered, the cell keeps replicating. Hm, sounds familiar. Retinoblastoma normally keeps the cell from growing too fast or responding to growth stimulators. And so, without these two mechanisms to slow down cell growth and prevent mutation. . . Preventing HPV infection is very difficult.
Most infections are asymptomatic, yet transmissible.
Also cofactors such as smoking and number of sexual partners can increase the risk of actually developing neoplasias or malignant transformations. Vaccines Vaccines have yet to be developed for Human Papillomavirus. Lone L1 and L2 proteins self-assemble into a capsid that is identical to the complete virion. So, a antibody-mediated response is mounted before the body actually comes into contact with the live virion. For these vaccines, researchers are targeting the activity of the E6 and E7 oncoproteins.
