(A) Immune profile of KPAR and KPB6 orthotopic tumours compared to normal lung, assessed by flow cytometry.
(B) Frequency of tumour-infiltrating T cell populations and NK cells.
(C) Percentage of effector memory CD8+ (left) and CD4+ (right) T cells.
(D) Quantification of PD-1, LAG-3 and TIM-3 expression on CD8+ (left) and CD4+ (right) T cells.
(E) Representative plot of PD-1 and LAG-3 expression on CD8+ T cells.
(F) Frequency of PDL1+ macrophages, cDC1, cDC2, monocytes and neutrophils. Tumours were analysed 21 days after transplantation. In (B)-(D) and (F), data are mean ± SEM, n=4 mice (KPB6) or 9 mice (KPAR), symbols represent pooled tumours from individual mice. Unpaired, two-tailed Student’s t-test; ns P>0.05, * P≤0.05, ** P≤0.01, *** P≤0.001, **** P≤0.0001.
