PG - 231-44 AB - Dendritic cells (DCs) are highly specialized professional antigen presenting cells that have a potent capacity for stimulating naive, memory and effector T-cells. They are located in lymphoid organs as well as in almost all nonlymphoid tissues. Immature DCs, residing in the host microenvironment, respond to danger signals with maturation, a differentiation process along which they acquire the ability to direct the extent and the type of primary immune responses according to the type of danger perceived. In this review we present some of our approaches and experiences regarding the isolation of human monocytes from peripheral blood and the in vitro preparation of, first, immature and then mature DCs by applying several maturation factors: bacterial lipopolysaccharide (LPS), a defined mixture of recombinant pro-inflammatory cytokines, monocyte conditioned medium (MCM) and TNF-alpha alone. The assessment of DC phenotypes and their functional capabilities as well as some of the techniques used for tumour associated antigen loading are also presented. The results of such studies represent a basis for optimal in vitro preparation of DCs, which could be clinically used to modulate immune responses in cancer, autoimmune diseases and in the planned onset of tolerance to disparate major histocompatibilty complex (MHC) antigens prior to tissue or organ transplantation.
