Combined phospholipids adjuvant augments anti-tumor immune responses through activated tumor-associated dendritic cells.

ABSTRACT: Dendritic cells (DCs) can initiate both naïve and memory T cell activation, as the most potent antigen-presenting cells. For efficient anti-tumor immunity, it is essential to enhance the anti-tumoral activity of tumor-associated DCs (TADCs) or to potently restrain TADCs so that they remain immuno-stimulating cells. Combined phospholipids (cPLs) adjuvant may act through the activation of DCs. This study demonstrated the potential mechanism of tumor growth inhibition of cPLs adjuvant, and confirmed that cPLs adjuvant could induce the maturation and activation (upregulation of MHC-II, CD80, CD40, IL-1β, IL-12, IL-6 expression) of BMDCs in vitro. Then we isolated tumor infiltrating lymphocytes (TILs) from solid tumor and analyzed the phenotype and cytokines of TILs. The examination of the TILs
