IL1B and cancer: detected that tumor‐loaded α‐type 1‐polarized dendritic cells cocktail (IL‐1β/TNF‐α/IFN‐α/IFN‐γ/poly‐I:C;αDC1) showed a better tumor therapeutic efficiency by producing more NK cell‐, NKT cell, and CD8 +  T cell‐recruiting chemokines CXCL9, CXCL10, and CXCL11 in the culture supernatants, as compared with the “standard” cocktail (IL‐1β/TNF‐α/IL‐6/PGE2;PGE2DCs), indicating the key role of the three chemokines in cancer treatment 109.
