Recent studies have shown that in cervical cancer, Poly(I:C), an adjuvant for cancer vaccine, may act through the NF-κB signaling pathway to promote the expression of M1-type cytokines (such as IL-1β and IL-6) and inhibit the expression of M2-type cytokines (such as IL-10 and CCL22) [174]. This evidence concerns the gene IL6 and cancer.
