Figure 4. Immunofluorescence of lamin A/C in cells infected with HCMV.
At 96 hours p.i. (MOI = 1), cells were fixed and double-stained with a mouse monoclonal antibody against UL44, a replication compartment marker (red, left panels) and a goat antibody against lamin A/C (green, center panels). Signals from both antibodies were merged (right panels). (A) Wild-type HCMV strain AD169 (AD169) infected cells show characteristic deformation of the nuclei. The nuclei of cells infected with AD169 in the presence of 5 µM maribavir (AD169+MBV) (B) or in cells infected with UL97 deletion mutant virus RCΔ97 (Δ97) (C) retain the oval shape characteristic of mock-infected cells (mock) (D).
