    The phenotype and functions of monocyte-derived dendritic cells (DCs), generated upon stimulation with GMCSF and IFN-α, were investigated in pulmonary tuberculosis (TB). Patient INF-DC cultures were characterized by increased number of CD14+ cells, lowered level of CD25+ cells and increased expression of B7-H1. Besides, DCs produced enhanced levels of IL-6 and IL-10 and differed by reduced secretion of INF-γ and INF-α. Patient IFN-DCs had lower capacity to stimulate allogeneic T-cell proliferation and induce CD3+IFN-γ+ T cells but increased ability to activate CD3+IL-4+ T cells in mixed lymphocyte culture. The most pronounced increase of IL-10 production, as well as the decrease of allostimulatory activity and the alteration of T1/T2 stimulatory activity of DCs were registered in patients with low PP..
