Research Abstract

We have demonstrated that EBV-encoded small RNA (EBER) is released by EBV infected lymphocytes and released EBER activates the signaling from toll-like receptor3, a sensor of viral RNA. Our results also suggest that activation of TLR3 signaling by EBER contribute to the pathogenesis of active EBV infection. We also demonstrated that released EBER activates TLR3-mediated signaling in EBV-infected gastric cancer cells.
