CCR7 and Increased total eosinophil count: We found that patients with blood eosinophilia (eosinophil count > 450/μL blood) and non-eosinophilia (eosinophil count < 450/μL blood) had similar percentages of circulating CCR7+ memory CD4+ T cells, but both subgroups of patients had a higher percentage of CCR7+ memory CD4+ T cells than non-asthmatic control subjects (Fig. 2a).
