Harnessing the Funnel-web spider venom to block cell death after a stroke.
1. Blocking Acid-Sensing Ion Channels
The Australian **Funnel-web spider** is one of the world's deadliest. However, scientists at the **University of Queensland** have isolated a molecule called **Hi1a** from its venom. This is a **proven scientific fact**: Hi1a can effectively block "acid-sensing ion channels" (ASICs) in the brain, which are responsible for massive cell death following a stroke [1, 2].
During a stroke, the brain becomes acidic. This acidity triggers cells to "suicide." Hi1a stops this signal, potentially saving millions of neurons even hours after the initial event.
Clinical Breakthrough
As of 2025/2026, clinical trials in Australia are accelerating. This is no longer just a laboratory curiosity; it is a leading candidate for the world's first drug that can actively **stop the progression of brain damage** while a patient is in the ambulance.
