For instance, BALF granulocytic markers, such as eosinophilia/neutrophilia, eosinophil cationic protein, and interleukin-6 (Riise et al. 1999) (Scholma et al. 2000), may herald the development of chronic allograft dysfunction, though, interestingly, they also represent biomarkers for acute cellular rejection, a well-established clinical risk factor for OB. Here, IL6 is linked to Increased total eosinophil count.
