HMGB1 and neoplasm: In an attempt to investigate whether the partial maturation of cDCs upon co-culture with oHSV1-FLT3L-induced oncolysates was due to the release of damage-associated molecular patterns (DAMPs), we measured the release of HMGB1 and ATP upon treatment of tumor cell lines with oHSV1-FLT3L for 24 h and 48 h.
