Fig. 9From: Alpha5 nicotinic acetylcholine receptor mediated immune escape of lung adenocarcinoma via STAT3/Jab1-PD-L1 signallingα5-nAChR promotes tumour growth and immune escape by upregulating PD-L1 in C57BL/6 mice model. A Stable α5-nAChR overexpression upregulated PD-L1 expression. B The morphology of tumour xenografts from each mouse was photographed. C The expression level of PD-L1, CD4 and GB within tumour xenografts in each group of C57BL/6 mice, N = 5 mice/group.
