OBJECTIVE: To address the role of cord blood (CB) CD25+ CD4+ T cells, the gene
expressions and function of this subset were analyzed. MATERIALS AND METHODS:
CD25+ CD4+ T cells fractionated from CB of term and preterm infants were subjected to flow
cytometry, quantitative polymerase chain reaction analysis for cytokines, costimulatory
molecules, and transcription factors, and functional assays. RESULTS: Human preterm CB
contained a high proportion of CD25+ CD4+ T cells that declined with gestational age to the …
