Freshly isolated mouse 4F7+ splenic dendritic cells process and present exogenous antigens to T cells.
1994
The antibody 4F7 was reported to recognize an epitope expressed on dendritic cells (DC) from various tissues. To study the ability of splenic 4F7+ dendritic cells to process antigen for presentation to CD4+ T cells, DC were enriched using a separation procedure avoiding overnight culture which could lead to an altered phenotype. These DC were used as antigen-presenting cells (APC) in stimulation cultures of major histocompatibility complex class II-restricted T cells. It was found that they induce antigen-dependent lymphokine production by T cells and therefore could present exogenous antigens. These processing takes place intracellularly, because fixation abrogates presentation to T cells.…
Processing and Presentation of Protein and Parasite-Derived Antigens by 4F7+ Dendritic Cells
1995
The dendritic cell (DC), a trace component of splenocytes is the principal cell type required for a primary mixed lymphocyte reaction.1 Splenic DC are described as antigen presenting cells (APC) capable to generate immunogenic fragments of intact protein antigens for presentation to MHC class II restricted T cells,2 in contrast to former findings.3 Langerhans cells (LC) as potent APC are members of the dendritic cell lineage forming a system of potent APC, first identified by Steinman and Conn.4 Importanly Schuler and Steinman have subsequently presented experimental evidence suggesting that LC represent immature DC.3 During infectious diseases caused by parasites of the genus Leishmania LC…
