Given that we noticed that BDCA-1+/BDCA-3+ cDCs were infected by oHSV1-FLT3L, we assessed whether the virus is cytotoxic for BDCA-1+/BDCA-3+ cDCs by analyzing their viability using flow cytometry at different time points (24, 48, and 72 h) after infection. This evidence concerns the gene FLT3LG and infection.
