Insights
Diabetes elevates cardiovascular disease risk by increasing inflammatory monocytes. Understanding enhanced myelopoiesis in diabetes is key to finding new treatments for diabetic heart disease.
Area of Science:
- Cardiovascular Medicine
- Endocrinology
- Immunology
Background:
- Diabetes is a primary risk factor for cardiovascular disease (CVD), the leading cause of death in diabetic patients.
- Elevated levels of inflammatory monocytes are observed in diabetic individuals and are linked to atherosclerosis development.
- Preclinical diabetes models show increased monocyte production and activation due to enhanced myelopoiesis.
Purpose of the Study:
- To investigate the mechanisms driving enhanced myelopoiesis and inflammatory monocyte generation in diabetes.
- To explore potential therapeutic targets for reducing cardiovascular risk in diabetic patients.
- To deepen the understanding of diabetes pathophysiology concerning cardiovascular complications.
Main Methods:
- Review of preclinical studies in type 1 and type 2 diabetes models.
- Analysis of factors promoting monocyte proliferation, including hyperglycemia, impaired cholesterol efflux, and inflammasome activation.
- Focus on bone marrow precursor cell proliferation.
Main Results:
- Enhanced myelopoiesis contributes to increased monocyte production and activation in diabetes.
- Hyperglycemia, impaired cholesterol efflux, and inflammasome activation are key factors promoting myelopoiesis.
- Inflammatory monocytes play a significant role in atherosclerosis development in diabetic conditions.
Conclusions:
- Further mechanistic studies on myelopoiesis and monocyte generation are crucial.
- Understanding these processes can reveal new therapeutic strategies for diabetic cardiovascular disease.
- Targeting enhanced myelopoiesis may reduce cardiovascular risk in patients with diabetes.
Abstract:
Diabetes is the greatest risk factor for the development of cardiovascular disease, which, in turn, is the most prevalent cause of mortality and morbidity in diabetics. These patients have elevations in inflammatory monocytes, a factor consistently reported to drive the development of atherosclerosis. In preclinical models of both type 1 and type 2 diabetes, studies have demonstrated that the increased production and activation of monocytes is driven by enhanced myelopoiesis, promoted by factors, including hyperglycemia, impaired cholesterol efflux, and inflammasome activation, that affect the proliferation of bone marrow precursor cells. This suggests that continued mechanistic investigations of the enhanced myelopoiesis and the generation of inflammatory monocytes are timely, from the dual perspectives of understanding more deeply the underlying bases of diabetes pathophysiology and identifying therapeutic targets to reduce cardiovascular risk in these patients.

Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
