In a normal immune response interferons (IFN) are produced to alert surrounding cells of the presence of a pathogen. This response activates STAT1, which increases production of immune fighting genes in cells, by phosphorylation. STAT1 is brought to the nucleus by karyopherin α proteins. Ebola protein VP24 binds to karyopherin α1, α5, and α6, making it unable to transport the P-STAT1 to the nucleus. | In a normal immune response interferons (IFN) are produced to alert surrounding cells of the presence of a pathogen.
