Fig. 6. Response of human MF to celastrol treatment. Human monocyte-derived MF were subject to LPS activation (100 ng mL⁻¹) and celastrol treatment at varying doses (1–10 μM). The expression of both M1-associated (A) and M2-associated (B) genes is presented as gene counts relative to untreated (M0) controls; M1 controls (red) are included for reference.
