Research Abstract

In many cancer patients, immune system is subverted by immunosuppressive cells as well as tumor-derived factors, which contributes to tumor progression. Tumor-associated macrophages with immunosuppressive, M2-like phenotype support the tumor growth by several mechanisms. Here, we show that double-stranded RNA(dsRNA) adjuvant induces growth retardation of 3LL tumor by converting tumor-supporting macrophages to tumoricidal effectors through the activation of TLR3-TICAM-1 signaling pathway
