Although an initial study concluded CCR3 was absent on neutrophils (Höchstetter et al., 2000), subsequent studies reported CCR3 expression on human neutrophils isolated from patients with chronic lung disease (Hartl et al., 2008) and on neutrophils isolated from the BAL fluid of mice infected with influenza (Rudd et al., 2019). The gene discussed is CCR3; the disease is chronic lung disease.
