"Methylglyoxal and the brain microcirculation: The source matters"

The small blood vessels in the brain are crucial for maintaining healthy brain function. When these vessels are affected by disease, a condition called cerebral small vessel disease, it is common in older adults. People with diabetes, a condition characterised by high blood sugar, are at an increased risk for this disease, though the reasons remain unclear. This thesis explores the role of methylglyoxal, a reactive byproduct of sugar metabolism, in the development of cerebral small vessel disease. Using animal models, data from The Maastricht Study, and cell cultures, we investigated the effects of methylglyoxal. Our findings suggest that while methylglyoxal levels are elevated in people with diabetes, they do not directly harm small brain vessels in otherwise healthy individuals. However, the way methylglyoxal forms in the body may still influence disease development. The source of methylglyoxal is crucial to consider for future research, as it may help identify potential targets for treating cerebral small vessel disease in people with diabetes.
