Care must be taken with interferons. EBV is a very clever virus and takes advantage of the increase in IFN-γ produced during the antiviral response to infect new cells. Since IFN-γ enhances the immune response by increasing the expression of MHC-II in cells so that they present more antigens. This increase in MHC-II is exploited by EBV to infect new cells through gp42-MHCII interaction that previously did not express it.
@Manuel very interesting! Thx! But I would need a little clarification on how to look at it - I have VERY low IFN-γ in my blood tests. How to read it in conjunction with EBV according to what you write?
