Nitrogen-doped carbon nanotube cups (NCNC) loaded with paclitaxel (Pac) block TGF-β production by tumor-associated MDSC. Bone marrow MDSC were sorted from tumor-free and B16-bearing mice (3 weeks), incubated with medium (Control), empty NCNC and NCNC/Pac. TGF-β was measured by ELISA. *, p<0.05 (vs controls in tumor-free mice; **, p<0.05 (vs NCNC Pac).
