In a cohort of obese women with and without asthma (N = 11 and 15, respectively), followed for 12 months after bariatric surgery, although BAL cytokines were overall similar in asthmatics and controls, BAL IL-8 and MCP-1 levels were higher in asthmatics at 12 months compared to their baseline [32]. This evidence concerns the gene CXCL8 and asthma.
