One of the more technical yet fascinating aspects I discussed was freeze substitution, a technique performed at -90°C, where water remains mobile, but larger molecules are immobilized. During this process, we introduce acridine orange and uranyl acetate, which results in a "fluffy" structural visualization—a revealing view into the delicate architecture we're studying. What I want the audience to understand is the crucial role of the glycocalyx—not just as an isolated structure, but as a dynamic, functional layer of the cell surface. It plays a vital role in cell behavior, communication, and vascular integrity, and its condition changes dramatically between health and disease. My personal focus is on the impact of diabetes. In diabetic patients, the glycocalyx becomes disrupted, which contributes to a host of microcirculatory problems—in the kidneys, retina, and lower limbs. These complications are common and devastating, and they correlate strongly with glycocalyx degradation. We believe the glycocalyx is a key player in diabetic vascular complications, and our hope is to one day restore or rebuild a healthy glycocalyx, which could help reestablish proper endothelial function and ultimately preserve vascular health. This research opens a door not just for better understanding, but for potential therapeutic interventions—aiming to consolidate the vasculature and mitigate the progression of diabetes-related organ damage.
