In addition to detection of EBV-specific latent transcripts such as EBV-encoded latent membrane proteins 1 and 2 (LMP1 and LMP2) and EBV-encoded nuclear antigen 1 and 2 (EBNA1 and EBNA2), as well as lytic transcripts such as BZLF1, they have additionally revealed that the basal level of epithelial EBV-infection is significantly increased in chronic periodontitis [17]. This evidence concerns the gene PDLIM7 and periodontitis.
