ANPEP and tuberculosis: Figure 2B shows a representative analysis of surface markers expression in terms of Geo-MFI in one patient with active TB. As shown in Figure 2C, both neutrophil populations expressed the myeloid surface markers CD33, CD66b, CD11b, CD10, CD15, CD13, CD16, and HLA-DR, but LDNs showed significantly elevated expression of CD66b, CD33, CD15, and CD16 cell surface molecules, when compared to NDNs population.
