Fig. 7From: Downregulation of the PD-1/PD-Ls pathway in peripheral cells correlates with asbestosis severityCorrelations between PD-1 expression and FVC% predicted in patients with asbestosis. PD-1+CD4+ T cell fractions (r = 0.591, P = 0.008) (a) and PD-1+CD8+ T cell fractions (r = 0.507, P = 0.027) (b) positively correlated with FVC predicted. FVC, forced vital capacityBack to article page
