Lack of HPV16 Infection in the absence of cathepsin B. HPV16 infection levels in cathepsin B and cathepsin L deficient (-/-) and wild type (+/+) MEF cells were analyzed and compared 48 hours post binding by FACS analysis of GFP expression. Cells alone were analyzed for background fluorescence. Statistics were analyzed by 1 tailed t-test and found to have a significant difference at P < 0.05.
