Scientists Identify Key Mechanism Driving Epstein-Barr Virus Spread and Potential Therapeutic Target

Research reveals how EBV hijacks immune cell migration to spread systemically, with new inhibitors showing promise in preclinical models.

Overview

  • Epstein-Barr virus (EBV) manipulates immune B cells to mimic 'homing cells,' enabling them to traverse blood vessel walls and spread throughout the body.
  • Viral proteins EBNA2 and LMP1 drive this migration by increasing pro-inflammatory cytokines, such as CCL4, and activating CCR1 and FAK-dependent pathways.
  • Researchers at DKFZ and Heidelberg University Hospital demonstrated that blocking these pathways with specific inhibitors reduced the survival and spread of EBV-infected B cells in animal models.
  • This breakthrough could inform targeted therapies for EBV-associated diseases, including multiple sclerosis and cancers like Burkitt’s lymphoma.
  • Clinical validation of these inhibitors in humans is the next step, offering hope for novel treatments to prevent viral dissemination and related diseases.
