[Retracted] IFN-γ induces PD-L1 through p38/JNK/ERK signaling pathways and counteracts the tumor promoting effect mediated by PD-L1 in Glioblastoma

Figure 2

IFN-γ upregulates PD-L1 expression via the p38/JNK/ERK signaling pathways. PD-L1 expression was detected after incubated with SB203580 (a), SP600125 (b), and U0126 (c) in U251, TG-905, and PT-2, prior to IFN-γ (50 ng/mL).
