Blood keeps us alive, but what happens when it clots too much—or not enough? Join us for a fascinating journey into the world of platelets and fibrin, the tiny players behind blood clotting. Discover how they heal injuries, but also how they can turn against us, leading to strokes or heart attacks. From life-saving glue to dangerous blockages, find out why balance is everything!
Platelets: small but mighty

Discover the power of platelets! Learn their role in clotting, their discovery, and how they can contribute to cardiovascular disease, turning from healers to culprits in heart health.

Blood Clots: Heroes or Villains?
Dr Thembaninkosi Gaule
(Postdoctoral Research Fellow)
Blood clotting is a lifesaver, stopping bleeding when we’re injured. At its core is fibrinogen, which transforms into fibrin—a sticky "glue" that holds clots together. Other proteins then strengthen the clot, making it stable. But balance is key! If fibrin is too weak, we risk excessive bleeding; too strong, and dangerous clots can form, causing strokes or heart attacks. Understanding how fibrin structure affects clot stability could lead to better treatments, keeping our blood flow just right.
