The absence of increased counts of CD3+ and CD8+ T lymphocytes on day 4 of acute RV infection in subjects with asthma alone is not in keeping with increased subepithelial CD3+ and CD8+ cells at day 6 reported previously.11 This inconsistency may be due to differences in timing of the biopsies, as the present specimens were taken at day 4 vs day 6. This evidence concerns the gene CD8A and asthma.
