These are surveillance cells found in all tissues and, as specialised antigen presenting cells, direct Received in revised form immune responses. Membrane molecules on the DC surface form a landscape that defines them as leu- 14 December 2017 cocytes and part of the mononuclear phagocytic system, interacts with their environment and directs Accepted 10 February 2018 interactions with other cells. This review describes the DC surface landscape, reflects on the differ- Available online 27 March 2018 ent molecules confirmed to be on their surface and how they provide the basis for manipulation and translation of the potent functions of these cells into new diagnostics and immune therapies for the Keywords: clinic.
