The new skin cell culture technique enables high infection rates of keratinocytes by HPV16, a human papillomavirus (HPV) type that is particularly strongly linked with cancer, report researchers.
According to the researchers, most HPV infections cause no symptoms, but certain types of HPV are associated with cervical, throat and other cancers.
Human Papillomavirus Infection
Human papillomavirus (HPV) infection, depending on the human papillomavirus that causes it, can result in common warts or can cause cervical cancer.

HPV infects skin cells known as keratinocytes before they have fully matured, or differentiated, and are still dividing into new cells. During the final stages of differentiation, uninfected cells cease division, but HPV makes infected cells keep dividing, the researchers said.
For the study, published in the journal PLOS, the research team took inspiration from recent reports that, before entering a keratinocyte, HPV16 binds to the extra cellular matrix -- a mesh of proteins and carbohydrates outside of the cell that performs a variety of structural and molecular functions.

Human papillomavirus (HPV) infection is the most common sexually transmitted infection spread by person to person contact, mainly sexual intercourse and affecting the skin and genital areas. There are over 100 types of HPV and some types can cause cervical cancer. Take this quiz to test your knowledge on HPV.
They found that high infection rates could be achieved by incubating HPV16 with extra cellular matrix materials in a dish, and then seeding it with keratinocytes.
They analysed RNA from infected cells at different time points to determine which HPV genes were expressed and when.
They also infected cells with mutant HPV16 viruses lacking different genes, revealing which viral proteins were essential to establish infection.
The researchers included Malgorzata Bienkowska-Haba, Timothy R. Keiffer among few others from the Louisiana State University in the US.
