摘要

The absolute number of circulating CD4~+CD25~+Foxp3~+ regulatory T lymphocytes (T_(reg)) was elevated in children with transient hypogammaglobulinemia of infancy (THI), but not common variable immunodeficiency (CVID) and selective IgA deficiency (SlgAD), as we previously reported (see Rutkowska et al. [1]). Our follow-up studies performed on THI children revealed a consistent decrease in T_(reg) cell numbers over time that was associated with the normalization of serum IgG levels. Molecular mechanisms responsible for T_(reg) generation in humans are still poorly understood. However, the requirement of transforming growth factor beta (TGF-beta) signaling in the generation and maintenance of T_(reg) cells is well defined [2].
