This virus was derived from a Chinese NPC patient and has shown high expression level of lytic genes such as BZLF1 and BALF in the M81-infected cells .
Several studies have also evidenced that lytic proteins such as BZLF1, BRLF1, and BRMF1 could be potential therapeutic targets but further investigations and validations are warranted [49, 55, 70].
Raji cell line models expressing EBV latent infection showed that H3K4me, H3K27me3, and H4K20me3 repress BZLF1 transcription, leading to reactivation of EBV .
Although EBV is not integrated into the host genome, its materials such as EBNA1 and BZLF1 seem to interact with various cellular promoters and induce epigenetic alterations that are associated with carcinogenesis.

However, it includes CD8 T cell epitopes from other EBV early antigens, such as EBNA1, EBNA3, EBNA6, BMRF1, BRLF1, and BZLF1 (Tables 1 and 5).

However, several groups have demonstrated that SLE patients have abnormally high expression of several viral mRNAs (coding for BZLF1, gp350, viral IL10, LMP1, LMP2, and EBNA1) [54, 59].
Contrarily, CD8+ cytotoxic T-cells specific for the two lytic cycle EBV antigens, BZLF1 and BMLF1, have been detected in synovial fluid and synovial membranes of RA patients, indicating a contribution of infiltrated cytotoxic T-cells specific for EBV lytic cycle antigens in joint inflammation [84, 85].
Eight out of 12 SS saliva samples were found to have an activating effect on the BZLF1 promoter in EBV-negative BZLFl-transfected salivary gland cells, indicating a possible frequent reactivation of EBV in the oropharynx of SS patients .
