Epstein Barr Virus
  • Strongly associated with sinonasal (NK) lymphomas
  • Associated with monoclonal B cell lymphoproliferative disorder (high grade) and immunosuppression (methotrexate) for autoimmune disease
  • Expresses LMP1, which prevents apoptosis via bcl2 interaction
  • Expresses EBER1, which transactivates host genes
EBER1 & EBER2
  • EBV encoded RNA
    • Nuclear RNA portions of EBER 1 and 2 genes
  • Interpretation: nuclear stain
LMP
  • Latent Membrane Protein of EBV
  • Interpretation: cytoplasmic or membranous staining
