AB The mechanisms regulating the onset of atopic sensitization in human
beings are not yet fully clarified. We assessed the capacity of
mitogen-stimulated umbilical and peripheral blood mononuclear cells to
produce interferon-gamma (IFN-gamma) and interleukin-2 (IL-2) at birth
and at 9 months of age in 159 infants. Mononuclear cell production of
both IFN-gamma and IL-2 at 9 months, but not at birth, was found to be
inversely related to parental immediate skin test reactivity to seven
local aeroallergens. Skin test reactivity at the age of 6 years was also
inversely related to IFN-gamma and IL-2 production at 9 months of age.
However, no relationship was evident between total serum IgE levels at 6
years and production of these cytokines at 9 months. The proportions of
circulating lymphocytes and CD4+ or CD8+ cells were also unrelated to
skin test reactivity at the age of 6 years. These data suggest that
mechanisms regulating skin test reactivity to inhaled allergens may
involve deficient IFN-gamma production, deficient IL-2 production, or
both during or preceding the time of initial sensitization and that
additional mechanisms are involved in regulating total serum IgE level.
