E6 produces a protein that binds to and inactivates a protein in the host cell known as p53. Typically, p53 acts to protect against cell growth, and promotes cell death in the presence of DNA damage. In quick, p53 is a tumor-suppressor protein that arrests the cell cycle and prevents cell development and survival when DNA damage occurs.

In 2009, a group tested Australian Red Cross blood samples from 180 wholesome male donors for HPV, and subsequently located DNA of a single or far more strains of the virus in 15 (eight.three%) of the samples. As such, it remains to be determined regardless of whether HPV can or can’t be transmitted through blood.
