Antibody-enhanced NS1 expression in infected B cells. DV2 was incubated with normal human serum or DV3 immune serum before infecting B cells of donors 4, 5, and 8 at an MOI of 1. At 48 h p.i., infected cells were collected and subjected to flow-cytometric analysis of the viral NS1 protein. The results are expressed as the mean percentages of cells that express the NS1 protein of DV ± SEM.
