For example, Hamsten and colleagues recently drew attention to the differential expression of chemokine ligand 5 (CCL5), hematopoietic prostaglandin D synthase (HPGDS), and neuropeptide S receptor 1 (NPSR1) in the plasma of children with asthma using an antibody-based proteomic array [73]. This evidence concerns the gene NPSR1 and asthma.
