Decreased CLEC1A expression in lung transplants is predictive of CR. Lung transplants from stable patients or from patients prior to the development of CR were subjected to qRT-PCR for HPRT, CLEC1A, IL17A, IFNG, and TGFB1. Results were expressed in histograms as mean ± SEM of 7 samples in each group and were expressed in AU of specific cytokine/HPRT ratio. *P < .05; **P < .01. mRNA, messenger RNA.
