Why the study?
The study aimed to investigate the influence of statins on the secretion of angiogenesis mediators by peripheral blood mononuclear cells derived from patients with type 2 diabetes.
Does low-dose atorvastatin alter the secretion of angiogenic factors by peripheral blood mononuclear cells in patients with type 2 diabetes?
Does low-dose atorvastatin alter the secretion of angiogenic factors by peripheral blood mononuclear cells in patients with type 2 diabetes?
Low-dose atorvastatin exhibits antiangiogenic activity by reducing proangiogenic factors and increasing antiangiogenic IL-10 secretion by PBMCs in patients with type 2 diabetes.
Statin-treated T2DM patients show reduced proangiogenic PBMC mediators; leaves open whether this affects vascular outcomes in diabetes.
The aim of this study was to investigate the influence of statins on the secretion of angiogenesis mediators by the peripheral blood mononuclear cells (PBMCs) derived from patients suffering from type 2 diabetes. The study group comprised 30 participants and included: 10 statin-treated patients with diabetes, 10 statin-free diabetic subjects, and 10 statin-free non-diabetic individuals. PBMCs isolated from the blood were cultured in vitro in standard conditions and in an environment mimicking hyperglycemia. Culture supernatants were evaluated for VEGF, MCP-1, Il-10, and Il-12 by flow cytometry using commercial BDTM. Cytometric Bead Array tests. The secretion of VEGF, MCP-1 and Il-12 by PBMCs, cultured both in standard and hyperglycemic conditions, was significantly lower in the statin-treated patients with type 2 diabetes in comparison with the statin-free diabetic patients. Conversely, the secretion of Il-10 was higher in the statin-treated than in the statin-free diabetic patients. VEGF, MCP-1 and Il-12 levels in PBMCs supernatants from the glucose-containing medium were higher than those from the standard medium in each of the diabetic groups. The results of the study suggest that statins in low doses exhibit an antiangiogenic activity, reducing the secretion of potent proangiogenic factors, such as VEGF and MCP-1, and increasing the secretion of antiangiogenic Il-10 by PBMCs, also under hyperglycemic conditions characteristic for type 2 diabetes.
