Enhancement of B19V infection by CQ in HepG2 cells and BMMCs.

<p>Panel A shows the quantification of viral DNA synthesis from HepG2 cells 90 h after infection with B19V in the presence of increasing CQ concentrations (0–200 µM). The results are the average of three independent experiments. SD bars are shown. Panel B shows the quantification of viral DNA replication at increasing post-infection times in untreated and CQ-treated (25 µM) HepG2 cells. Panel C shows the quantification of viral RNA transcription in HepG2 cells at increasing post-infection times in the presence of 0 or 25 µM CQ. Values shown in panels B and C represent the average of two independent experiments. SD bars are shown. Panel D shows the quantification of viral RNA transcription in BMMCs at increasing post-infection times in the presence of 0 or 25 µM CQ. Results represent mean values from two independent experiments. SD bars are shown.
