Macrophages in Immunopathology of Atherosclerosis: A Target for Diagnostics and Therapy
نویسندگان
چکیده
Immunopathology plays important roles in the development of different life-threatening diseases, such as atherosclerosis and its consequences (acute myocardial infarction and stroke), cancer, chronic inflammatory diseases. Effective modulation of the immune system may significantly increase the efficacy of prevention and therapy efforts. Currently there are no marketed drugs capable of normalizing immune system function in an intrinsic and comprehensive way. Here, we describe a test system designed for complex analysis of monocyte activity in individuals to diagnose immunopathology and monitor treatment efficacy. This cell-based test system may also be useful for screening compounds with an immune-correcting effects. Both diagnostic and screening systems are based on primary culture of human monocytes and/or monocyte-derived macrophages. This is the first step in creating a method for assessment of macrophage activity, which is required for further development of immune-correcting drugs. The existing preliminary data provide the basis for realization of this idea.

Monocyte Activation in Immunopathology: Cellular Test for Development of Diagnostics and Therapy
Several highly prevalent human diseases are associated with immunopathology. Alterations in the immune system are found in such life-threatening disorders as cancer and atherosclerosis. Monocyte activation followed by macrophage polarization is an important step in normal immune response to pathogens and other relevant stimuli. Depending on the nature of the activation signal, macrophages can a...
متن کاملLOX-1 protein, A Biomarker in the Prognosis of Atherosclerosis
LOX-1 is a class E scavenger receptor that mediates the uptake of oxLDL by vascular cells. LOX-1 is involved in endothelial dysfunctions, monocyte adhesion, the proliferation, migration, and apoptosis of smooth muscle cells, foam cell formation, platelet activation, as well as plaque instability; all of these events are critical in the pathogenesis of atherosclerosis. These LOX-1-dependent bio...
متن کاملInvestigation of the effect of trimethylamine-N-oxide on the proinflammatory cytokine genes expression in U937-derived macrophages
Background and Aim: Atherosclerosis is known as a multifactorial inflammatory disease. Trimethylamine N-oxide (TMAO) as a risk factor, has a potential to trigger or enhance the immune inflammatory reactions in atherosclerosis. Yet, The exact mechanism by which TMAO induces inflammation during atherosclerosis is not well understood. The present study was designed to evaluate the expression of IL...
متن کاملInhibitory effect of Cinnamon on prevention of foam cell formation in platelet and monocytes co-culture
Introduction: Atherosclerosis is one of the leading causes of cardiovascular disease. Following endothelial damage and platelet aggregation in that area and the recruitment of monocytes and their conversion to macrophages, LDL gradually accumulates under the endothelial artery wall and gradually oxidized and convert to oxi-LDL. By swallowing it, the macrophages turn into foam cell and then athe...
