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

Results indicated higher phagocytic index of treated groups (at dose rate of 100 and 200 mg/kg body weight), which may be due to reticuloendothelial system stimulation (Neha and Mishra, 2011; Hajra et al.
3) Merozoites released from these schizonts enter erythrocytes to become gametocytes or other hepatic cells to form hepatic schizonts, or develop in cells of the reticuloendothelial system as megaloschizonts.
Patients with AIHA and warm RBC autoantibodies do not have the spontaneous agglutination of RBCs but can still have significant hemolysis as the RBCs coated with autoantibodies are removed by the reticuloendothelial system, which also presents with signs and symptoms of anemia and hemolysis.
Leukopenia observed initially was probably as an effect of peripheral destruction of cells in reticuloendothelial system or liver impairment as both of the effects were observed in our study.
The causes of anaemia in malaria include increased destruction of infected as well as uninfected RBCs by reticuloendothelial system, dyserythropoiesis in bone marrow, depressed reticulocytes response in acute malaria, hypersplenism and folate deficiency.
The reasons for this are the transfer of bacteria from the intestinal lumen to the mesenteric lymph nodes, portal and systemic circulation and the existence of portosystemic shunts, damaged functions of reticuloendothelial system which lead to reduced removal of bacteria and endotoxins from the portal circulation [4, 5].
The questions address such areas as anesthesia/analgesia, cardiovascular, first aid and transport, fluids and electrolytes, hematology, neurology, ophthalmology, parasites, polysystemic disease, shock/sepsis, reproduction, the reticuloendothelial system, trauma, and urinary.
This vascular channel lacks a well-developed reticuloendothelial system (RES) allowing for an ideal location for pathogens to deposit (2,4,13) and replicate while evading host defenses (2).
As the diameter is smaller than 50 nm, the MPEG-PEI-SPIONs can avoid the phagocytosis of reticuloendothelial system (RES) and are designed to have a much longer blood half-life and could rapidly circulate almost the whole body.
Spleen is the main reticuloendothelial system where anti- platelet antibodies are produced and autoantibody- platelet complex is destroyed.
8) In addition, IL-1 and TNF-[alpha] induce ferritin transcription, which increases iron storage in the reticuloendothelial system.
