Gao and colleagues [28] highlighted how patients with neutrophilic asthma, defined by neutrophils ≥61% in sputum samples, had lower levels of Gal-3 than patients with paucigranulocytic (sputum eosinophils ≤ 3% and neutrophils < 61%) or eosinophilic (sputum eosinophils ≥3%) asthma. This evidence concerns the gene LGALS3 and asthma.
