29.1 million people have Type II diabetes, a chronic disease where the body’s insulin levels are altered, and β-cells of pancreas does not function properly. This causes the blood glucose levels to rise above normal and eventually create severe health circumstances. Recent research has correlated this chronic disease with red blood cells rather than blood vessels, and scientists are undergoing further investigation to discover preventative care treatments.
Hemoglobin, a protein that makes up 95% of red blood cells, helps to carry oxygen from the lungs to the rest of the body. This molecule attaches to glucose and remains there for as long as up to three months, which is recorded as HbA1c. Most of the red blood cells have a lifespan of 3-4 months. When this concentration of HbA1c reaches higher than the average concentration, it means that there are elevated levels of glucose in your blood and it is critical to managing your glucose levels.
Some short-term complications with Type II diabetes are sleepiness, headaches, rapid heart rate, sweating, and numbness in fingers, toes, and lips. If left untreated, Type II diabetes can develop into more serious complications such as affecting the eyes, kidneys, heart, brain, and blood vessels. The Centers for Disease Control and Prevention (CDC) have noted that now people who have diabetes are more prone to cardiovascular injury such as heart attacks.
New Study Shows How Diabetes Attacks the Blood
Previous studies had claimed that healthy blood vessels’ tissues were damaged when they came into contact with red blood cells. Current research has shown that red blood cells are the targeting factor that is damaged, which leads to increased risks of strokes and heart attacks.
Blood vessels help in transporting glucose and insulin throughout the body. If there are high glucose levels, it was assumed previously that the clotted vessels lead to advanced glycation end products (AGEs); hence organs cannot be adequately fed. Now, the research focus is towards the innermost cell layer of the red blood cells which is made up of endothelial cells. With the in-depth understanding of diabetes, the root cause has been found to be the abnormal activity of the enzyme- arginase produced by endothelial cells.
Scientists have observed that patients with diabetes have an up-regulation of arginase and reactive oxygen species within the red blood cells. This is significant as newer avenues targeting arginase can prevent cardiovascular complications. Hopefully, with advances in research and scientific studies, there will be a solution for the complications of diabetes and red blood cells arginase could potentially be the next therapeutic target.
