Figure 8From: The E5 protein of the human papillomavirus type 16 down-regulates HLA-I surface expression in calnexin-expressing but not in calnexin-deficient cellsHPV16 E5, M2 and M3 mutants but not M1 mutant strongly co-localize with calnexin. HaCaT cells were transfected with A) AU1-tagged codon-optimised E5 or AU1- tagged codonoptimised E5 mutants M1 B), M2 C), and M3 D) and analysed after 24 h by confocal laser scanning microscopy using a monoclonal anti-AU1 and polyclonal anticalnexin antibodies.Back to article page
