The present application provides compositions and methods for producing
antigen presenting cells (APCs) from
cancer cells (e.g., hematological
cancer cells) that involve one or more agents selected from a STAT3 activator (e.g., IL-10), IFNγ
receptor activator (e.g., IFNγ ), TNFα
receptor activator (e.g., TNFα), IL-4
receptor activator (e.g., IL-4), GM-CSF receptor activator (e.g., GM-CSF), and / or IL-6 receptor activator (e.g., IL-6). APCs produced accordingly are also provided, as well as methods of activating immune cells (e.g., T cells) via co-culturing with APCs. The activated immune
cell compositions and the methods of treatments that involve the activated immune cells are also provided.
