A recent study identified Interleukin-18 as a trigger for Eosinophilic esophagitis, a chronic immune disease affecting children. The research suggests that inhibiting the protein’s release could prevent the disease and proposes an existing drug, VX-765, as a potential treatment. Eosiniphilic esophagitis was not identified as a disease until the 1990s. Decades later, a treatment may have been discovered. A new study from Tulane University has identified a new treatment for a chronic immune system disease that can prevent children from eating. Eosinophilic esophagitis (EoE) is triggered by food allergies or airborne allergens which causes a type of white blood cell, eosinophils, to build up in the lining of the esophagus. This causes the esophagus to shorten and the esophageal wall to thicken, making swallowing difficult and causing food to get stuck in the throat. Disease Prevalence and Newly Identified Cause The disease occurs in an estimated 1 in 2,000 adults but more frequently affects children (1 in 1,500) where symptoms can be harder to diagnose and pose greater risks as difficulty feeding can lead to malnutrition, weight loss, and poor growth. The new study, published today (July 31)  in Nature’s Communications Biology journal, found that the disease is caused by Interleukin-18 (IL-18), a protein involved in the innate immune response that can cause inflammation if produced in excess. When a food allergen enters the body, it activates a pathway responsible for regulating the innate immune system, resulting in the release of proinflammatory proteins like IL-18. This produces the eosinophils which damage the esophagus. Discovering Potential Treatment The study found that successfully inhibiting this pathway, called the NLRP3 pathway, and the release of IL-18 prevented the development of EoE from both food and airborne allergens. “Parents and doctors may not be aware of this, but this is a very prominent and serious disease in the pediatric population, and it is increasing in number because it is directly related to food allergens, which are also on the rise,” said lead author Dr. Anil Mishra, director of the Eosinophilic Disorder Center at the Tulane University School of Medicine. “In this study, we show that after treating the disease in animals, the disease is gone and completely in remission.” The Study’s Impact The findings are crucial for a disease that was not identified until the 1990s. For many years, EoE was misdiagnosed as gastrointestinal reflux disease (GERD), despite GERD medication being ineffective for treating EoE. Additionally, this study’s findings replace decades of thinking that Th2 cells play a major role in triggering EoE. “Given the paucity of mechanistic information and treatment strategies for EoE, we feel the proposed studies are highly relevant and are poised to have a major impact on establishing the significance of NLRP3-IL-18 pathway in the initiation of EoE pathogenesis,” Mishra said. The Next Steps The study identified one existing drug, VX-765, as an inhibitor that may work as a treatment for humans. Importantly, this inhibitor would only deplete pathogenic eosinophils generated and transformed by IL-18 and not affect white blood cells created by IL-5, a protein important for maintaining innate immunity. Mishra said a clinical trial would be the next step to determining the treatment’s effectiveness.

A recent study reveals that ultraviolet radiation alters the microstructure of human skin, particularly impacting collagen, causing the skin to become tougher. This research provides insights into the biological reason behind the “leathery” skin appearance observed in individuals exposed to the sun for extended periods. Researchers found that prolonged UV exposure makes skin stiffer by causing collagen fibers to pack more tightly, aligning with aging theories that suggest accumulated molecular bonds lead to dysfunction. Common belief holds that prolonged exposure to the sun can eventually toughen your skin. Consider the “leathery” skin of farmers, road crew members, and others who spend extensive hours outdoors, or individuals who frequent tanning booths or beaches during the summer. However, despite these observations, minimal research has been conducted to explain why this happens on a biological level — until now. A study from Binghamton University researchers recently published in the Journal of the Mechanical Behavior of Biomedical Materials explores how ultraviolet radiation can alter the microstructure of human skin. Particularly affected is collagen, the fibrous protein that binds together tissue, tendon, cartilage, and bone throughout our bodies. How UV Light Alters Collagen Structure “We don’t want to put a fear factor in here saying ‘don’t go out in the sun,’” said Binghamton University Associate Professor of Biomedical Engineering Guy German. “But extended periods of time under UV light can toughen up your skin as well as lead to a higher risk of carcinogenic problems.” Leading the research with German at the Thomas J. Watson College of Engineering and Applied Science’s Department of Biomedical Engineering are Ph.D. student Abraham Ittycheri, Zachary Lipsky, Ph.D. ’21, and Assistant Professor Tracy Hookway. The new study builds on previous research from German and Lipsky that focused on the outer stratum corneum, which is the top layer of skin. This time, the Binghamton team compared full-thickness skin samples before and after various levels of UV exposure. “One way to characterize the material characteristics of skin is by conducting a mechanical stretch test on it,” Ittycheri said. “If it stretches very easily, it’s relatively compliant, but if it’s much harder to stretch it, you can characterize it as much stiffer. My experiment was to see what the isolated effects of UV light would be and compare it with a scenario where a skin is not exposed to UV light.” The researchers found that as the skin absorbed more UV radiation, the collagen fibers in it became more tightly packed together, leading to increased stiffness and tissue that is harder to break. German sees correlations with the cross‐linkage theory of aging, which proposes that the accumulation of undesirable molecular bonds over time can cause cellular dysfunction. Aging and Cellular Response to UV Damage Hookway — who won a National Science Foundation CAREER Award earlier this year for her research on cardiac cells — sees similarities between how heart and skin cells deal with damage, even though they have very different functions. “Our body has this natural response in any tissue when there’s some sort of injury, which likely happens in the stratum corneum,” she said. “First, wherever there’s some sort of weakening, there has to be compensation by some other part of the tissue or else there’ll be catastrophic failure. The same thing happens in the heart when you have a myocardial infarction — you build up a scar and your heart’s going to not work the same way anymore.” Sometimes, she added, the body’s reaction will keep you alive but isn’t necessarily a good result, possibly leading to other medical issues later. Figuring out the mechanics of how it all happens could allow future doctors to steer the reactions in a healthier direction. Following this research, further collaborations among Ittycheri, German, and Hookway are already in the works. Our skin is the body’s largest organ and the first line of protection against microbes and other outside attacks, so ways to maintain and even strengthen it are clearly beneficial. “Any kind of disruption to the normal process of skin is going to be extremely dangerous and detrimental to our overall lifestyle,” Ittycheri said. “That’s not even going into the cosmetic side of things, where a person’s perception about themselves can be challenged when their skin does not look good.” Reference: “Ultraviolet light induces mechanical and structural changes in full thickness human skin” by Abraham Ittycheri, Zachary W.

Phoneutria boliviensis in the Peruvian Amazon. Credit: N. Hazzi Scientists have found that the venomous spider P. boliviensis is actually two species, correcting misidentifications in venom studies and improving public health insights. Spiders from the genus Phoneutria — also known as banana spiders — are considered aggressive and among the most venomous spiders in the world, with venom that has a neurotoxic action. These large nocturnal spiders usually inhabit environments disturbed by humans and are often found in banana plantations in the Neotropical region. One of these spiders, P. boliviensis, is a medically important species widely distributed in Central and South America, whose behavior, habitat, venom composition, toxicity and bites on humans have already been paid considerable attention in previous research work. Nevertheless, after examining a large pool of museum specimens, biologists from The George Washington University (N. Hazzi and G. Hormiga) began to wonder if samples named P. boliviensis were actually belonging to one and the same species. Everything started when N. Hazzi was examining specimens of banana spiders identified in the past by experts as P. boliviensis. The research team quickly realized that the morphological features currently used to identify this species were not sufficient. Then, they discovered two well-defined morphological groups of P. boliviensis that were separated by the Andean mountain range, a geographic barrier that separates many other species. Genetic and Morphological Evidence Confirms Two Distinct Species To prove that these two “forms” were different species, the authors conducted fieldwork in the Amazon, Andes, and Central America, collecting specimens of these venomous spiders to explore if the genomic signal also suggests two species. They discovered that genetic differences separating these two forms were similar compared to the genetic differences separating other recognized species of banana spiders. Using morphological, genomic and geographic distribution data, the authors concluded that P. boliviensis represents not a single species, but two different ones. They uncovered that the true P. boliviensis was only found in the Amazonian region, and the second species, P. depilata (an old name revalidated by the research team), was found in the Andes, Chocó and Caribbean regions. Their findings are published in the open-access, peer-reviewed journal ZooKeys. To obtain more distribution records for these species, the research team used the citizen science platform iNaturalist. Since the two species are among the few spiders that can be identified using only images, the platform turned out to be a very helpful tool. Data submitted by the iNaturalist community helped identify where the two species of Phoneutria are found. Curiously enough, for these two species, iNaturalist presented higher and more widely distributed records than the scientists’ own database. “To our knowledge, this is the first study that has used iNaturalist to gather occurrence records on venomous species to estimate distribution models,” the researchers say. This is how the two spiders can be distinguished using only photographs: P. boliviensis has two lateral white-yellow bands in the anterior area of the carapace, while P. depilata has four series of yellow dots in the ventral side of the abdomen. In addition, for P. depilata’s identification, information is needed on where the image was taken, because this is the only species of Phoneutria found in the Andes, Chocó, and Central America. However, the most reliable approach to identify these species requires examination under a stereomicroscope. Implications for Venom Studies and Public Health Interestingly, P. depilata has been mislabeled as P. boliviensis throughout many studies, including works on venom composition and toxicity, ecology, geographic distribution, and human epidemiology of bites. There have been human bite records of this species reported in Costa Rica and in banana plantations in Colombia, most of them with mild to moderate envenomation symptoms. Except for brief anecdotal mentions by field explorers in the Amazon, little is known about P. depilata. The study provides detailed diagnoses with images to distinguish both species and distribution maps. “This valuable information will help identify risk areas of accidental bites and assist health professionals in determining the identity of the species involved, especially for P. depilata. This is a significant discovery that will affect studies about toxicology, opening new opportunities to compare the venom composition and the effect of these two species,” the authors conclude.
