Specifically, the acute myeloid leukemia (AML)-specific mutated NPM1 (mNPM1)-derived neoantigen CLAVEEVSL was delivered to DCs in the form of αCD40mNPM1 and αCD40.FlgmNPM1 antibody constructs, making this study the first to investigate mNPM1 in a DC vaccination context. The gene discussed is NPM1; the disease is acute myeloid leukemia.
