Death Cap Mushroom

May 18, 2023

The death cap mushroom, scientifically known as Amanita phalloides, carries a notorious reputation for its deadly consequences when consumed. With liver failure and even kidney failure as potential outcomes, this mushroom poses a significant threat to those who mistakenly ingest it. Recently, a research has identified a potential antidote for the death cap mushroom, offering a ray of light in the fight against its toxicity.

Understanding the Lethal Consequences

Consuming the death cap mushroom can have devastating effects on the liver and, in some cases, the kidneys. The toxins within this mushroom can cause irreversible damage and ultimately lead to death. Recognizing the urgent need for a countermeasure, researchers have sought to identify a solution that can combat the mushroom’s deadly properties.

The Potential Antidote: Indocyanine Green

Scientists from China’s Sun Yat-sen University have focused their attention on indocyanine green, a dye already approved by the Food and Drug Administration (FDA) for medical diagnostic imaging purposes. Through their research, they have discovered that this substance has the potential to combat the toxicity of the death cap mushroom and prevent cell death caused by its toxins.

Insights into the Research

The research team adopted a multi-step approach to understand the mushroom’s toxicity. They conducted genome-wide CRISPR screening on human cell lines, which revealed the significant role played by a group of proteins called N-glycans in cell death. Furthermore, they identified an enzyme known as STT3B as a key contributor to the mushroom’s toxicity.

Promising Results

In their quest for a solution, the researchers found that indocyanine green could inhibit the enzyme STT3B. They observed that when human cell lines, including HAP1 and Hep G2, were pre-treated with indocyanine green, they exhibited increased resistance to toxin-induced cell death. Encouraged by these findings, the researchers conducted tests on live mice. Injecting the toxin and subsequently treating the mice with indocyanine green after four hours resulted in less organ damage, lower cell death, and higher survivability among the treated group.

Optimizing Treatment

Although indocyanine green shows promise as an antidote, its effectiveness diminishes after 8-12 hours. Therefore, seeking treatment as early as possible is crucial to mitigate the mushroom’s impact. Immediate action is essential to provide the best chance of counteracting the deadly consequences of the death cap mushroom.
