| pubmed-article:11071646 | pubmed:abstractText | Dendritic cells (DCs) have the unique ability to initiate an immune response in vivo by capturing antigens (Ags) in peripheral tissues and migrating to secondary lymphoid organs, where they sensitize naive CD4(+) T cells. To mimic this process in vitro, previous studies have shown that DCs directly isolated from peripheral blood can be used to elicit primary responses to neoantigens (neoAgs). In other studies, when monocyte-derived DCs have been utilized to sensitize total CD4(+) T cells in vitro, only secondary proliferation to neoAgs could be elicited. In the present study, the relative abilities of CD40 ligation, protein kinase C activation, and culture in tumor necrosis factor alpha (TNF-alpha) to induce functional and phenotypic maturation of human DCs from monocyte precursors were compared. Optimal TNF-alpha-induced maturation of DCs required a prolonged 4-day culture. It was then found that loading immature DCs with the neoAgs keyhole limpet hemocyanin or human immunodeficiency virus-1 p24 gag prior to TNF-alpha-induced maturation, rather than after maturation, was crucial to sensitize CD4(+) T cells to new Ags. This primary proliferation to neoAgs was initiated from the CD4(+) CD45RA(+) naive T-cell population. Finally, it was found that monocyte-derived DCs acquired the ability to secrete interleukin-12 p70, after contact with Ag-specific T cells. The ability to prime and expand Ag-specific CD4(+) T cells ex vivo to neoAgs in serum-free conditions has potential application for cellular vaccination and adoptive immunotherapy. | lld:pubmed |
