General description.4 are immortalized murine dendritic cells created by transducing bone marrow isolates of C57BL/6 mice with retrovirus vectors expressing murine granulocyte-macrophage CSF (GM-CSF) and the myc and raf oncogenes . DC2.4 exhibits characteristic features of dendritic cells including cell morphology and the expression of dendritic cell-specific markers and the ability to phagocytose and present exogenous antigens on both MHC class I and class II molecules .
Dendritic cells (DC) are the antigen presenting cells of the immune system and are found in most tissues, particularly those that are in contact with the external environment (e.g., skin and the inner linings of the nose, lungs, stomach and intestine). First described in 1973 , one of the primary functions of DCs is to phagocytose foreign pathogens and present the processed antigens to naïve T cells to regulate adaptive immune responses. DCs also express Toll-like receptors and help regulate the innate immune responses. Despite their distribution in most tissues, DC are present at low numbers in vivo and are difficult to maintain in vitro. These difficulties have limited the studies of dendritic cells.
