Figure 3: Analysis of mesothelioma FNA by flow cytometry characterizes tumor immunophenotype.

(A,B) Immunoprofiling revealed high expression of inhibitory receptors on CD8+ T cells (A) and CD4+ T cells (B) on both tumor and FNA, but not blood. Left panel represents % positivity of inhibitory receptors for individual samples (B = blood, F = FNA, T = tumor) and right panel depicts Mean % positivity of inhibitory receptors ± SEM across dataset.
