| Sumario: | Dendritic cells are specialized antigen-presenting cells which are required to involve naive T-lymphocytes into immune response. Dendritic cells are used in numerous research studies, and have also found practical application as a main component of dendritic cell vaccines. In vitro induction of their maturation from monocytes using cytokines is the most widely used method to obtain these cells. In present study, we compared phenotypes of both immature and mature dendritic cells induced from monocytes of adult healthy donors by means of recombinant cytokines provided by different manufacturers. It is shown that recombinant human IL-4 and GM-CSF supplied by sci-store.ru could effectively stimulate in vitro differentiation of human monocytes to immature monocytic dendritic cells. The resulting immature dendritic cells exhibited a typical morphology and phenotype characterized by the absence of CD14 monocyte marker as well as HLA-DR and CD80 costimulatory molecule expression. A fraction of these cells expressed the CD86 costimulatory molecule. The recombinant human IL-6 from sci-store.ru, when used in a mixture of inflammatory mediators (IL-6, IL-1β, TNFα and PGE2), has induced effective terminal differentiation of immature dendritic cells to mature dendritic cells exhibiting typical morphology and phenotype. Virtually all dendritic cells obtained with this reagent were devoid of CD14, and expressed HLA-DR, CD80, CD83 and CD86 at high fluorescence intensity. |
