IL-4 and CD40 ligation affect differently the differentiation, maturation, and function of human CD34+ cell-derived CD1a+CD14- and CD1a-CD14+ dendritic cell precursors in vitro.


We examined the effect of interleukin (IL)-4 or CD40 ligation on the differentiation and maturation of CD1a+CD14- and CD1a-CD14+ dendritic cell (DC) precursors. Cord blood CD34+ cells were cultured with granulocyte-macrophage colony-stimulating factor (GM-CSF) and tumor necrosis factor alpha (TNF-alpha), to which stem cell factor and Flt-3 ligand were added… (More)
