Medical science has not yet been able to explain why the Epstein-Barr virus triggers infectious mononucleosis (IM) in some people with initial infections and not in others. But now, a research team led by Elisabeth Puchhammer-Stöckl, head of the Center for Virology at MedUni Vienna, has identified a specific immune response to the virus as the cause, and as a potential target for the development of vaccines. The findings were recently published in the American Society of Hematology’s journal Blood.
Proliferation of the Epstein-Barr virus (EBV) in humans is normally combated by T cells as part of an antiviral immune response. By means of this important mechanism, certain EBV components (peptides) are presented to the T cells by a specific1LA-E molecules on EBV-infected cells.
