PG - 415-419 LID - 10.4049/immunohorizons.2000011 [doi] AB - Dendritic cells (DCs) play a key role in the initiation of an immune response and are known as "professional" APCs because of their ability to activate naive T cells. A widely used method to generate DCs in vitro is to culture bone marrow (BM) cells or blood monocytes in the presence of GM-CSF and IL-4. In this study, we show that a small population of NK cells residing in the BM of RAG(-/-), but not RAG(-/-) gamma(c) chain(-/-) mice, remain in the DC culture and is the source of IFN-gamma produced after stimulation with LPS. These cells, which may represent early promoters of LPS-induced responses, have to be taken into account when interpreting experiments using BM-derived DCs.
