re·tic·u·lo·en·do·the·li·al system

The diffuse system of cells that destroy pathogens by phagocytosis, originally thought to include cells of the reticular tissues of the spleen, liver, bone marrow, and lymph nodes along with a variety of endothelial cells, all of which take up dye introduced into the bloodstream. This term has been largely replaced by "mononuclear phagocyte system" and restricted to the monocytes and macrophages.

[reticul(um) + endothelial.]

reticuloendothe′lial sys`tem

the aggregate of the phagocytic cells that have reticular and endothelial characteristics and function in the immune system's defense against foreign bodies. Abbr.: RES

It was thought that peliosis develops exclusively in organs that are part of the mononuclear phagocytic system, but studies have shown that other organs such as the lungs, parathyroid glands and kidneys may also be affected.
The spleens had increased numbers of mononuclear phagocytic system cells, some of which had vacuoles that contained similar organisms, as observed in the liver.
Our observations have the following implications: a) the visualization of red fluorescence (Figure 4A-C) suggest aggregation of a large number of QD705 nanocrystals in situ because fluorescence from one or a few particles of QD705 would have been invisible under the microscope; b) a major mechanism of disposition of QD705 involves mononuclear phagocytic system and organs.
