Antigen Presenting Capacity of Peritoneal Macrophages and Dendritic Cells
Dendritic cells (DC) are very potent antigen presenting cells (1), that can be isolated from many lymphoid and non-lymphoid tissues from different species (2). Recently, we have demonstrated that in the peritoneal cavity of rats approximately 1 % of the cells are DC, based on similar morphological and functional characteristics as DC isolated from lymphoid organs (3). Next to this small number of DC, a large number of Mϕ (macrophages) is present in the peritoneal cavity, which are also capable of presenting antigen although to a lesser extent. Both cell types are bone marrow derived (4), but there are numerous morphological and functional differences (5) that suggest the existence of different cell lineages.
