The pathogenic role of EBV lytic infection in NPC carcinogenesis. After primary infection, EBV establishes latent infection in B cells. Upon reactivation, lytically-infected B cells travel through the nasopharynx tissue, followed by infection of the nasopharyngeal epithelial cells by cell-to-cell contact.

Hesperetin inhibits KSHV reactivation and reduces the production … WebWe have now used iPSCs to develop a model cell system to study HCMV latency and reactivation in different cell types after their differentiation down the myeloid lineage. Our results show that iPSCs can effectively mimic HCMV latency/reactivation in primary myeloid cells, allowing molecular interrogations of the viral latent/lytic switch.
