Besides its roles in the maintenance of latent infection and epithelial-cell transformation, LMP2A could also act as the target for a CTL-based therapy for EBV-associated malignancies. In the present study, sequence polymorphisms in LMP2A from northern Chinese EBV-associated gastric carcinoma patients, nasopharyngeal carcinoma patients and healthy donors were identified and compared with the prototype B95-8 strain. Four consistent mutations were detected in all isolates. Frequent mutations in the analysed sequences distinguished two and seven types of sequence variation in exon 1 and exons 2-8, respectively, with no consistent association shown between the genotyping of the two gene fragments. The immunoreceptor tyrosine-based activation motif and PY motif in the amino terminus were strictly conserved. Nine of the 16 identified CTL epitopes were affected by at least one point mutation, which may confer complexity to proposed immunotherapeutic approaches for EBV-associated malignancies. Most changed epitopes showed higher mutation rates in tumour isolates than in throat-washing samples from healthy donors, in accordance with the idea that virus strains can evade immune surveillance by altering amino acids within LMP epitopes. This first detailed investigation of sequence variations in the LMP2A gene reveals classifiable sequence polymorphisms in exon 1 and exons 2-8, and encourages further work on the impact of viral gene variations on tumour persistence and CTL-based immunotherapy."xsd:string |
