The present disclosure provides a method of inhibiting
telomerase activity to reduce
human herpesvirus (e.g., HMCV, EBV, HSV-1, and / or HHV-6 / 7 / 8) replication. The method comprises treating cells with a
telomerase inhibitor prior to and after
HCMV infection. The
telomerase inhibitor may be a pharmaceutical inhibitor such as BIBR1532 or MST312, or an siRNA construct targeting the hTERT catalytic
subunit of telomerase. Treatment with the
telomerase inhibitor results in reduced viral
titer, decreased
viral gene expression, and diminished
viral protein levels across different temporal phases of
herpesvirus infection. The method provides a novel approach for inhibiting herpesvirus replication through targeting of host
cell telomerase activity.
