Fresh tissue samples from patients with OLP and healthy controls were carefully dissected. Protein concentrations were measured according to a BCA assay (Thermo Scientifc, Waltham, MA, USA) generated standard curve. A total of 40 µg of protein was denatured and then subjected to 12% SDS-polyacrylamide gel electrophoresis, followed by transfer onto polyvinylidene fuoride membranes (Millipore Corporation, Billerica, MA, USA). The membranes were incubated with primary antibodies (
anti-γδ TCR (Thermo Fisher, Catalog #5A6.E9),
anti-STING (Cell Signaling Technology, Catalog #D2P2F),
anti-NAK/TBK1 (Abcam, Catalog #EP611Y),
anti-p-STING (Cell Signaling Technology, Catalog #E9A9K),
anti-p-TBK1 (Cell Signaling Technology, Catalog #D52C2),
anti-IFN-γ (Abclonal, Wuhan, China, Catalog #A12450),
anti-IL-17A (Bioworld, Dublin, OH, USA, Catalog #BS6041), anti-HLA-DR (Nonus, CO, USA, Catalog #NBP2-67610) and anti-CCR6 (Bioss, Beijing, China, Catalog #BS-1542R)). After being washed, the membranes were then probed with secondary antibodies. Next, the blots were stained using an
enhanced chemiluminescence detection kit (Applygen, Beijing, China). The relative protein levels were calculated based on
β-actin (Proteintech, Chicago, IL, USA, Catalog #66009-1-Ig) as the loading control and were densitometrically analyzed by Image J software (NIH, Bethesda, MD, USA).
