Novel Skin Cell Culture Technique to Study HPV Developed

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.

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.
