Honey bees immune system and hiv-A Mushroom Extract Might Save Bees From a Killer Virus | WIRED

A mushroom extract fed to honey bees greatly reduces virus levels, according to a new paper from Washington State University scientists, the USDA and colleagues at Fungi Perfecti, a business based in Olympia, Washington. In field trials, colonies fed mycelium extract from amadou and reishi fungi showed a fold reduction in deformed wing virus and a 45,fold reduction in Lake Sinai virus compared to control colonies. Time is running out for bee populations and the safety and security of the world's food supply hinges on our ability to find means to improve pollinator health. This is the first research paper to come out of a partnership between Sheppard's lab and Fungi Perfecti. Their co-owner and founder Paul Stamets is a co-author on the paper.

British Medical Journal. Princeton Univ. To assess immune responses following natural infection, eight 1st-instar larval bees from the same stock were given per os challenges of P. To better understand what happens, we need to have a firm grasp of how the bee immune system functions. Just click on their ads to go to their websites. What makes it so special? Boyle P, Levin B. Global youth tobacco surveillance, — Have you tried propolis? The five Toll receptors present in the A.

The bees, as you've probably heard, are dying, in massive numbers.

  • I'd like to thank these sponsors for supporting this website.
  • Social insects are able to mount both group-level and individual defences against pathogens.

Recently, however, many researchers have been turning their attention toward how animals and animal products may have a potential role in modern medicine that the industry has yet to fully realize.

Demary and Nola J. Social immunity serves an important role in improving the health of a hive, but it provides benefits to humans as well. Ultimately, the authors assert that bees should be recognized as an essential keystone species in the field of zootherapy, adding to calls for their conservation. Apitherapy is practiced using a variety of bee products, all of which the article discusses in detail.

Here are just a few highlights:. Many hypotheses have also asserted that, beyond being a construction material, propolis is also used by bees as a sanitizing agent.

Propolis contains a variety of organic compounds called flavonoids, which have been shown to exhibit numerous antimicrobial properties. A controlled study demonstrated the effectiveness of propolis-based treatments over antibiotics in mitigating American Foulbrood, an often-devastating bacterial infection. Propolis contains a variety of active compounds which are useful to human health, dating back in medical history to Ancient Egypt. In lab-based experiments, wax has shown to be effective in the resistance of bacteria associated with American and European foulbrood, as well as stonebrood.

Venom is known for its use as a defense system in bees. Beyond being the primary cause of irritation following a sting, bee venom also contains a naturally antiseptic compound called melittin.

Melittin has shown effective resistance to a variety of bacteria. Honey bees have been shown to spread venom on their bodies and around the nest, likely for the purpose of staving off harmful pathogens. The natural presence of melittin in bee venom has led to a wide range of research considering its apitherapy applications. Studies of melittin as an anticancer agent have shown its effectiveness in inhibiting tumor growth in mice, as well as in limited clinical studies.

The antibacterial properties of bee venom have also shown potential for treating antibiotic resistant strains of bacteria such as MRSA, a methicillin-resistant pathogen which causes a variety of infections in humans that are currently difficult to treat. Studies in mice and isolated cells have shown a recovery from MRSA-caused infections following venom treatment, but further clinical research is required. Honey is unique in that it can be stored indefinitely without becoming a home for pathogens.

For example, a study showed that bees which fed on sunflower honey experienced a significant decrease in Nosema infection as opposed to those which fed on honeydew honey. Honey has been used as a wound treatment for millenia. In the context of modern medicine, it is a highly affordable and potent antibiotic which has proven effective in resisting MRSA, E.

Therefore, it has huge potential for wound treatment as it is so resistant to infection. Specifically, honey of the manuka flower from New Zealand has proven particularly effective.

Manuka honey was first approved for wound dressing by the United States Food and Drug Administration in , and is now used in a variety of wound dressing products. Many brands use medical grade honey, which is produced in greenhouse environments and designed to maximize antibacterial capabilities.

Bee bread is a very different product from raw pollen. Before being consumed, bee bread actually undergoes the same chemical process which gives things like sauerkraut and sriracha their distinct flavor.

Within the hive, bee bread is important as the primary source of food for larvae, and as the primary source of protein for worker and drone bees. Its high concentration of amino acids, lipids, and other micronutrients like vitamins make it essential for bee health and development.

Pollen enhances immune function in bees in a way which other food sources cannot. Recently, a major concern for bee health is that this immune function is being undermined by a low diversity of pollen-rich plant varieties on modern, monocropped farms.

Access to a wide variety of raw pollen creates a rounded micronutrient diet for bees, much like how humans benefit from eating a wide variety of vitamin-rich fruits and vegetables.

Bee bread has been shown to be an effective treatment in rabbits for conditions involving high cholesterol, even in contexts in which pharmaceuticals have not yet found a solution. Bee bread is also a known detoxifying agent, in some cases reversing the liver damage sustained by mice which had been poisoned.

In several additional studies, the introduction of bee bread to poisoned mice demonstrated high antioxidant activity, and sped up the removal of toxic substances from the bloodstream. Like many other bee products, bee bread has been shown to hold a variety of antimicrobial benefits. Notably, pollen extracts were shown effective in inhibiting the development of E. Coli , as well as several different kinds of yeast.

Royal jelly is a key food source in the development of larvae, and is the only food source for the queen bee throughout her lifetime. This allows her to live upwards of 2 years, compared to workers which live for only a few weeks in the summer.

Like bee bread, the primary substance from which it is created, royal jelly is abundant in protein and micronutrients. Due to its role in larval development, royal jelly is high in particular antimicrobial compounds that improve resistance to American foulbrood.

Royal jelly has also been found to contain octanoic acid, a substance which repels the destructive mite Varroa. Royal jelly is commonly sold as a nutritional supplement due to its abundance of amino acids, antioxidants, and vitamins. Research has been done demonstrating the possibly antitumoral properties of the product, but it has yet to be tested in the clinical setting.

While there are a number of possible applications of royal jelly in medicine, directly consuming it can be dangerous to humans. There have been documented cases of death and other severe cases as a result of an allergic reaction to the substance. Adding to calls for conservation of these essential pollinators, the recent review article out of the Urban Bee Laboratory demonstrates the importance of honey bees even outside of their own ecosystems. Oner advocate for designating honey bees as a keystone species in the field of zootherapy.

Ultimately, they assert that bee health is not simply limited to the hive, but is a vital component of human health as well. User Login. Propolis is typically glue-like but becomes brittle fragments when cooled.

What could cause such a suppression of the normal immune response? What does she mean by this? Picorna viruses have an unusual way of hijacking ribosomal function. But picorna viruses have figured out a way to sneak into the middle of the ribosome without a password Ongus Take a moment to grasp the implications of the above. Beekeepers will soon have at their disposal, from Beeologics, an antiviral medication that mimics the natural bee RNAi response.

Of note, is that in the Florida trial, the non-treated hive with the highest natural siRNA levels before and after infection had the highest bee population of the control group at the end-point analysis. In contrast, the two control hives that had no siRNAs either before or after infection were either dead or were extremely weak at the end point.

This finding indicates that colonies that are able to naturally ramp up an siRNA response to viruses are better able to survive. We fed the test hives Remebee prior to inoculating them with the virus cocktail, and then took samples two weeks after inoculation. It appears that treating hives with Remebee prior to virus exposure primes them to initiate a stronger antiviral response should they subsequently be exposed to the virus. They are looking for some commercial beekeepers who would like to test the product in their operations this winter.

The answer is that the viruses launch a preemptive strike by suppressing that immune response before it is initiated, and by further tweaking the ribosomal machinery to their benefit. This is akin to defeating an army by simply infiltrating its command headquarters and then rewriting the orders going out to the manufacturing sector, supply chain, and the troops. Narayanan This is cutting edge science, not yet thoroughly understood, but great strides are being made. Allow me to quote Scaria :.

The exclusive dependence of viruses on the host cellular machinery for their propagation and survival also make them highly susceptible to the vagaries of the cellular environment like short RNA mediated interference. These interactions can be further fine-tuned in the host by changes in gene expression, mutations and polymorphisms. In the pathogen, the high rate of mutations adds to the complexity of the interaction network. The last point of the above quote, about the high rate of viral mutations is of great import.

The RNA viruses are notable for their high mutation rate. Even the change of a single base molecule on the RNA strand can have a dramatic effect upon the virulence of the virus!

Shiboleth What we beekeepers observe in the field is the year-by-year evolutionary process in action, as some colonies fall sick with odd symptoms, then see the population rebound as resistant survivors supplant the less fortunate.

It is only recently that scientists even knew what to look for! Sick pupae, typical of a virus epidemic as varroa levels peak in September. Best I can tell is that they are dying from DWV or perhaps other viruses.

In the past decade, researchers have discovered that there are a whole set of genetic instructions whose functions had been previously overlooked. Realize that every type of cell gut, brain, hemocyte contains fine-tuned mechanisms to regulate the expression of each of the thousands of specific proteins needed for it to function.

However, I already had at least some strains of those viruses plus N. So I must be cautious about solely blaming the viruses as the initiating causal agents of colony collapse. I also, want to be clear that in this article I have extrapolated the current state of knowledge of similar viruses to the bee model, and that further work needs to be done before we can say that we definitively understand what is happening.

The exception to this live-bee rule is when the mid-aged hygienic bees transfer virions from virus-killed brood to other bees common with sacbrood and DWV, but not necessary for the transmission of either.

So go back to my discussion of viral replication. The question then is what exactly triggers the sort of multi-virus epidemics typical in collapsing colonies? What are the causal agents, and which are mere opportunistic pathogens?

So what happens when there are multiple parasites suppressing the bee immune system at the same time, and screwing with their ribosomal functions?

I will continue on that subject in my next article. RNAi is cutting edge science, the explanations of which are often buried in very arcane scientific journals; I thank Peter Borst for his tireless ferreting out of related research. I greatly appreciate the assistance of several scientists who have given their time to help clarify things for me. Through Prof.

Sela, I was introduced to RNAi, and to Nitzan Paldi, the inventor of the Remebee concept, with whom it has been a great pleasure to collaborate. I also wish to thank virologist Wayne Hunter, who brought his expertise with insect viruses to the USDA bee lab, and was a co investigator with me for the Remebee trials.

Finally, Jay Evans of the USDA lab, who has been a workhorse for CCD research and bee immune function, has always been there for me to bounce ideas against, and to whom we beekeepers all owe a debt of gratitude for his tireless efforts. I greatly appreciate the helpful reviews of the manuscript by Nitzan Paldi and Michelle Flenniken. Evans, J The role of multiple pathogens in colony collapse disorder. Martin, and DC.

Parallel Epigenomic and Transcriptomic Responses to Viral Infection in Honey Bees (Apis mellifera)

A mushroom extract fed to honey bees greatly reduces virus levels, according to a new paper from Washington State University scientists, the USDA and colleagues at Fungi Perfecti, a business based in Olympia, Washington. In field trials, colonies fed mycelium extract from amadou and reishi fungi showed a fold reduction in deformed wing virus and a 45,fold reduction in Lake Sinai virus compared to control colonies. Time is running out for bee populations and the safety and security of the world's food supply hinges on our ability to find means to improve pollinator health.

This is the first research paper to come out of a partnership between Sheppard's lab and Fungi Perfecti. Their co-owner and founder Paul Stamets is a co-author on the paper. After two years, we demonstrated that those anti-viral properties extend to honey bees. Stamets is passionate about the various benefits of fungi, both to humans and wildlife.

And he's been enjoying this partnership with Sheppard and his lab. For me, the best of science is when it is used for practical solutions. Our team is honored to work with WSU researchers and look forward to continuing collaboration. Right now, the mycelium extract isn't currently available in levels for beekeepers to purchase for their hives. Over the last decade, beekeepers have seen a disastrous decline in the health of honey bee colonies, often averaging over 30 percent loss annually.

Varroa mites, and the viruses they proliferate, play a major role in those losses. Deformed wing virus, which causes shriveled wings on bees, greatly reduces the lifespan of worker bees. Lake Sinai virus is also associated with varroa mites and is widespread in bee colonies around the United States. While the virus has no obvious or overt symptoms, it's an important virus to fight because it was found at higher levels in bees from collapsing colonies.

It is closely related to chronic bee paralysis virus and it likely makes bees sick and weak, according to WSU assistant research professor Brandon Hopkins. The treated bee colonies in this experiment were fed an oral treatment of mycelial extracts in dozens of small WSU bee colonies infested with varroa mites. Then it is expected that Fungi Perfecti will ramp up production.

There is currently no timeline for when the extract would be available at a scale large enough for beekeepers. Materials provided by Washington State University.
