4 EGFR inhibitor abrogates the up-regulation of PD-L1 due to RT in glioma cells
4 EGFR inhibitor abrogates the up-regulation of PD-L1 due to RT in glioma cells. EGFR signaling and PD-L1 proteins level in U251 and U87 cell lines were detected at 24, 48 and 72?h after 5 or 10?Gy irradiation. on the mRNA and proteins amounts in both cell lines was all considerably up-regulated ( em P…
