For example, chemokine (C-C motif) ligand 5 (CCL5), also known as RANTES, previously reported to be genetically associated with asthma [28,29], is differentially expressed between asthmatic and non-asthmatic cultures at both baseline (p = 0.026) and post viral infection (p = 0.047). The gene discussed is CCL5; the disease is asthma.
