Will protein design tools solve the snake antivenom shortage?

a year ago

Protein design tools like RFDiffusion are being used to create proteins that bind to snake venom toxins, potentially offering a new approach to antivenom production.
The current state of antivenom production is plagued by economic and logistical challenges, including high costs, supply shortages, and lack of profitability, especially in low-income regions.
Snake venom is highly heterogeneous, varying between families, species, populations, and even within individual snakes over time, complicating the development of universal antivenoms.
Traditional antivenom production involves injecting venom into animals like horses or sheep to produce antibodies, a method that hasn't changed significantly in over a century.
Computationally designed antivenoms could offer advantages such as increased stability and specificity, but their success depends on overcoming production and economic hurdles.
Recent research has identified broadly neutralizing antibodies from hyperimmune individuals, suggesting a path toward universal antivenoms, though challenges in scalability and cost remain.
The market for antivenoms is challenging due to low purchasing power in affected regions, but improved, universally effective antivenoms could potentially revitalize the market by increasing trust and demand.
