 AB    Variations in T lymphocytes in asthmatic patients are related to disease
       severity. However, the effects of natural exposure to pollens on
       peripheral blood T lymphocytes have not been clarified. In this paper,
       the effects on peripheral blood CD4 and CD8 lymphocytes from
       pollen-sensitive subjects and from nonatopic donors were studied during
       and outside the pollen season. In patients who suffer from seasonal
       asthma, we found an increase in the CD4/CD8 bright ratio and a decrease
       in the mean number of CD4 receptors per cell during the pollen season.
       No variation was observed in healthy subjects. These results suggest
       that CD4 lymphocytes may be causally linked to the pathogenesis of
       seasonal bronchial asthma.
