Rescue of MHC class II expression by ICSBP retrovirus transduction.

(A) Expression of MHC class II mRNA in ICSBP^+/+ or ICSBP^−/− DCs (left graph) or ICSBP^−/− DCs transduced with indicated vectors (right graph) was analyzed by real-time PCR. (B) Expression of promoter I–specific CIITA transcripts was analyzed by real-time PCR.
