From: Response of Nasopharyngeal Carcinoma Cells to Epstein-Barr Virus Infection In Vitro
Immunolocalization of EBNA-1, latent membrane protein (LMP)-1, interleukin (IL)-6 and EBV-viral capsid antigen (VCA) in NPC-TW 01 cell lines infected by EBV and incubated for 10 days. A, Anti-EBNA-1, shows some cells containing strong nuclear reaction product (arrows) and other cells contain moderate immunostaining (arrowheads); B, anti-LMP-1, shows some cells containing strong membrane staining (arrows) and other cells containing rather weak or no immunostaining (arrowheads); C, anti-EBV-VCA, shows no immunoreactivity; D, anti-IL-6, shows many cells containing strong cytoplasmic immunostaining (arrows) and a few cells containing very weak or no staining (arrowheads). (Bars in A to D, 20 μm.)
