CD4 and neoplasm: Consistent with these results, B7-H3 knockdown tumors grew faster in Cd4 KO mice than Cd8 KO mice (Supplementary Fig. 6e), with tumor size ~4-fold larger in Cd4 KO mice vs. control mice, and ~2.7-fold larger in Cd8 KO mice (Supplementary Fig. 6f), whereas the growth of the shRNA control cells was not different between Cd4 KO mice and Cd8 KO mice (Supplementary Fig. 6g, h).
