Abstract

BACKGROUND: The role of regulatory T (Treg) cells in allergic predisposition is not known.OBJECTIVE: This study compared the frequency and function of cord blood Treg cells from nonallergic children (n = 18) with those from children who have egg allergy (n = 15) in the first year of life.METHODS: CD...

Consistent with other reports, effector CD4(+) T-cell responses (IFN-gamma and IL-13) tended to be lower in the allergic group. These neonates showed less significant Treg cell-associated suppression of IFN-gamma (P = .015) compared with that seen in the nonallergic group (P = .001). The allergic group was also less likely (44%) to show Treg cell-associated suppression of IFN-gamma effector responses compared with that seen in the nonallergic group (78%, P = .015).
