In particular, a cocktail mixture containing tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and prostaglandin E2 (PGE2), is currently considered the gold standard for DC maturation and had been largely used in the context of anti-cancer therapeutic vaccines [19,20]. The gene discussed is TNF; the disease is cancer.
