Scientists at DTU have developed a new broad-spectrum nanobody-based antivenom that could revolutionize snakebite treatment, especially in Africa, by targeting multiple snake species with a safer, more stable, and cost-effective solution, though human trials are still needed.
A new antivenom made from llama and alpaca antibodies can neutralize venom from 17 African snake species, offering a broad-spectrum treatment that outperforms current options and reduces tissue damage, addressing a major public health issue in sub-Saharan Africa.
Scientists have discovered that antivenom treatment for mamba snakebites can sometimes worsen symptoms by unmasking hidden neurological effects, with different mamba species causing either limp or spastic paralysis, and effectiveness varies based on venom variation across regions.
New research shows that mamba snake venoms are more complex than previously thought, attacking the nervous system in multiple ways and varying by region, which complicates treatment and calls for specialized antivenoms to improve patient outcomes.
A study reveals that green mamba bites cause a unique form of paralysis called spastic paralysis, making treatment challenging as most antivenoms do not target this condition. The research highlights regional venom variations and the need for region-specific antivenom development, especially in India where snakebite deaths are high. Advances in monoclonal antibody treatments and increased research are crucial for better management of snakebite envenoming.
A study from the University of Queensland reveals that black mamba venom causes a dual neurological attack, leading to initial paralysis followed by severe spasms, which current antivenoms often fail to fully neutralize, explaining the high mortality rate from mamba bites in Africa and highlighting the need for improved treatments.
Tim Friede, who has been bitten over 200 times by snakes to develop immunity, has contributed to research that could lead to a universal antivenom, potentially saving thousands of lives annually from snakebites.
A toddler in San Diego was bitten by a rattlesnake, leading to a hospital bill of $297,461, primarily due to the high cost of antivenom. The child received 30 vials of Anavip, with prices varying significantly between hospitals. The incident highlights the exorbitant costs of medical treatment for snakebites in the U.S., driven by hospital markups and lack of competition in the antivenom market. The family's insurance covered most costs, but they still faced significant out-of-pocket expenses.
Scientists have developed a "blood-vessel-on-a-chip" to study how snake venom causes internal bleeding and to aid in the creation of new antivenoms. This 3D model mimics human blood vessels and reveals how different venoms damage them, potentially reducing the need for animal testing and improving snakebite treatments.
Researchers have made significant progress in developing a universal antivenom that can neutralize the effects of venom from any venomous snake by creating a lab-made antibody called 95Mat5, which can neutralize neurotoxins found in the venom of many snake species. This breakthrough could potentially replace traditional antivenoms, but additional antibodies are needed to neutralize other toxin types, and further research and human trials are required before a universal antivenom becomes available to snakebite victims.
Scientists at Scripps Research have developed a synthetic antibody effective against the venom of multiple deadly snake species, raising hope for a universal antivenom. This discovery could revolutionize snakebite treatment, as current antivenoms require separate manufacturing for each type of snake. The antibody, 95Mat5, was found to be effective in neutralizing venom from various elapid snakes in initial testing on mice. With proper funding, researchers aim to develop a "cocktail of antibodies" that could protect against all the world's deadliest snakes, potentially eliminating the need for hundreds of specific antivenoms.
Scientists at Scripps Research Institute have identified a potential universal antivenom for snakebites by screening human antibodies and discovering one that counteracts a protein in venom found in various snake species. The antibody, called 95Mat5, protected mice against venom from snakes including king cobras and black mambas. This breakthrough could be crucial for low and middle-income countries with high snakebite burdens, as existing antivenoms are specific to individual snake species. The researchers are now pursuing other broadly neutralizing antibodies to potentially create a universal antivenom cocktail against medically relevant snake venoms.
Scientists have made a significant breakthrough in developing a universal antivenom that can protect against the venom of various deadly snakes, including the black mamba and king cobra. The newly discovered human antibody, 95Mat5, has shown promising results in animal trials by preventing paralysis and death caused by venom from different elapid snakes. While this development is a crucial step forward, further research and clinical trials are needed before the antivenom can be made available for use in patients.
Researchers at Scripps Research have developed an antibody that can block the effects of lethal toxins in the venoms of a wide variety of snakes found throughout Africa, Asia, and Australia, representing a significant step toward creating a universal antivenom. The antibody, called 95Mat5, protected mice from the venom of snakes including black mambas and king cobras, and works by mimicking the structure of the human protein that the toxins usually bind to. This synthetic antibody could potentially work as a universal antivenom against medically relevant snake venoms worldwide, and the researchers are now pursuing broadly neutralizing antibodies against other snake toxins.
Researchers at DTU discovered that an antibody, previously considered a promising antidote to snake venom, unexpectedly enhanced the venom's toxicity in certain testing conditions, shedding light on a phenomenon known as antibody-dependent enhancement of toxicity (ADET). This finding has significant implications for the development of broad-spectrum antivenoms and could potentially expedite the process of creating effective treatments for snakebites, which claim the lives of over 100,000 people annually. The study, published in Nature Communications, marks the first observation of ADET in connection with animal venoms and underscores the complexity of antibody behavior in combating toxins.
