Recent studies from several laboratories suggest that the rate of postnatal maturation of T-cell function(s) associated with in vitro activation may be slower in children at high genetic risk for atopy (HR), compared to their normal (low risk; LR) counterparts. The present study compared the in vitro activity of the function-associated surface molecules CD2, CD3 and CD28 in panels of 27 HR and 13 LR infants, with a reference panel of 10 adults, employing assay systems involving T-cell stimulation with MoAbs against these molecules. The response maxima induced by saturating levels of the MoAbs were equivalent in all 3 groups, but T-cells from the HR infants required 10-50 fold higher levels of anti-CD3 stimulation to attain their maximum response, relative to adults (p = 0.02); T-cells from LR infants were also less responsive to anti-CD3 than adults, but these differences were smaller and did not attain statistical significance. It is suggested that these differences are attributable to varying proportions of competent T-memory cells (which respond to low levels of anti-CD3) in PBL from these populations, the postnatal accumulation of which proceeds slowest in the HR group.
