Abstract
Epstein-Barr virus (EBV) is the first human cancer-causing viral
pathogen to be discovered; it has been epidemiologically associated with
a wide range of diseases, including cancers, autoimmunity and
hyperinflammatory disorders. Its evolutionary success is underpinned by
coordinated expression of viral transcription factors (EBV nuclear
antigens), signaling proteins (EBV latent membrane proteins) and
non-coding RNAs, which orchestrate cell transformation, immune evasion
and dissemination. Each of those activities entail significant metabolic
rewiring, which is achieved by viral subversion of key host metabolic
regulators such as mammalian target of rapamycin (mTOR), MYC and
hypoxia-inducible factor (HIF). In this review, we systemically discuss
how EBV-encoded factors regulate metabolism to achieve viral persistence
and propagation, as well as potential research questions and directions
in EBV-driven metabolism.
