From: A novel method of modifying immune responses by vaccination with lipiodol-siRNA mixtures
In vivo immune modulation lipiodol/siRNA vaccine. C57/BL6 mice were immunized intradermally at the interior side of both hind legs with 100 μl of KLH or ovalbumin (1 μg/μl) emulsified in CFA in the presence or absence of 10 nMol siRNA and 10% lipiodol. After 14 days mice were sacrificed and T cell cytokine responses were assessed culturing purified CD4+ T cells with irradiated syngeneic splenocytes in triplicate and mixed with serial dilutions of antigen. IFN-γ in KLH (A) and ovalbumin (C) cultures, and IL-4 in KLH (B) and ovalbumin (D) cultures was assessed by ELISA.
