The red fire ant, Solenopsis invicta, native to South America, has made its debut in Europe, specifically in Sicily. Research indicates that this invasive species could spread rapidly across Europe, posing environmental, health, and economic challenges. (Artist’s illustration. See photos below.) The invasive red fire ant, native to South America, has been officially identified in Sicily, marking its introduction to Europe. Researchers warn of its potential rapid spread, posing major environmental and health challenges across the continent. One of the most invasive species in the world is Solenopsis invicta, a red fire ant species with a painful sting. Native to South America, the ant has established itself across the globe. In an article that will be published today (September 11) in the journal Current Biology, a group of ant experts confirm that the species has made its way to Sicily—the ant’s first official sighting in Europe. The ants could soon spread all over the continent, the researchers warn, which could cause major environmental, health, and economic problems in Italy and beyond. “S. invicta is one of the worst invasive species. It can spread alarmingly quickly,” says lead author Mattia Menchetti of the Institute of Evolutionary Biology in Spain. “Finding this species in Italy was a big surprise, but we knew this day would come.” Commonly known as the imported red fire ant, S. invicta’s name comes from the ant’s most infamous characteristic—its stings—which are painful and, occasionally, may cause anaphylactic shock.

Credit: Jesse Rorabaugh The Ant’s Global March Although it originated in South America, S. invicta has spread quickly, flying into wind streams to travel farther on the local level. But humans have also helped it spread both through the maritime trade industry and by shipping plant products, enabling it to establish in Australia, China, the Caribbean, Mexico, and throughout the United States in less than a century. Europe has evaded them for longer than expected, say the researchers. “There are a vast number of alien ant species currently establishing in Europe, and the absence of this species was kind of a relief,” says Menchetti. “For decades, scientists have feared that it would arrive. We could not believe our eyes when we saw it.” After seeing photos taken in Sicily of what looked like S. invicta, the researchers took a trip to the region to confirm the ants’ identity and collect samples. They found a total of 88 nests in a 4.7-hectare area next to a river, some of which housed many thousands of worker ants. After speaking with locals, the researchers learned that people in the Sicilian region had been getting stung—and frequently—for several years. “The locals have been experiencing these painful things since at least 2019, so the ants have probably been there for a while,” says Menchetti. “And the real extension of the invaded area is probably larger.” S. invicta nest in Sicily next to a river. Credit: Institute of Evolutionary Biology Origins and Predictions The team suspects that this wasn’t S. invicta’s first point of arrival in Europe. Although they couldn’t determine how exactly S. invicta got into Italy, after analyzing the DNA of the Sicilian queen ants and comparing it with the genomes of ants from all over the world, the researchers concluded that this particular population likely came from either the US or China. Next, the authors analyzed the local wind patterns in Sicily to see how the ants might spread now that they’re in Europe. They also put together a comprehensive model to determine how suitable the rest of Europe and the Mediterranean area will be for the species—and whether climate change will be a factor. According to the model, 7% of the European continent is suitable for S. invicta given current environmental conditions, and climate change will likely expedite their spread and population growth even further. They also found that urban areas are particularly at risk. In fact, 50% of Europe’s cities are vulnerable to invasion. “This is especially concerning because many of the cities, including London, Amsterdam, and Rome, have large seaports, which could allow the ants to spread rapidly to more countries and continents,” says senior author Roger Vila, who is also from the Institute of Evolutionary Biology in Spain.

Credit: Institute of Evolutionary Biology Eradication and Public Involvement Given that the only place that has successfully eradicated the invaders is New Zealand, the researchers plan to base their interventions on what worked there and on efforts currently underway in China. To start, they’ll systematically inspect local areas to see if the species has already reached them. Then, they’ll begin a multi-year treatment plan to eradicate the nests and monitor the invaded sites carefully to make sure there aren’t any resurgences. The authors stress the importance of getting the public involved as much as possible to help monitor the ants’ spread. “Citizens can play a very important role in this,” says Menchetti. “We hope that, with their help, we will be able to cover a wider area. This will help us track and spot all the possible areas invaded in the region.” The team hopes to organize citizen science programs in which people would look for S. Invicta and take photos if they think they’ve found the ants. The specialists would then double-check to confirm that it’s the right ant species—an important step because many European ants make similar-looking nests. “There needs to be more awareness about this problem because the problem is already in Europe,” says Menchetti. “We need coordinated action, and we need it now.” Reference: “The fire ant Solenopsis invicta is established in Europe” by Mattia Menchetti, Enrico Schifani, Antonio Alicata, Laura Cardador, Elisabetta Sbrega, Eric Toro-Delgado and Roger Vila, 11 September 2023, Current Biology.

Credit: Lo lab, UC Riverside Biomedical scientists from UC Riverside state that the cells resemble M cells found in the gut and airways. It came as a surprise to Professor David Lo and his graduate student Diana Del Castillo when they were recently consulted by researchers in Israel for their expertise on specialized cells called Microfold cells, or M cells, which are mostly known for their presence in the intestinal epithelium. The Israeli group had identified similar cells in the thymus, an organ located just above the heart that makes lymphocytes — white blood cells that play an important role in the immune system and protect the body against infection. Lo, a distinguished professor of biomedical sciences in the UC Riverside School of Medicine, and Del Castillo, who are co-authors on the research paper published in Nature, confirmed the newly discovered cells in the thymus are just like M cells. Acting like gatekeepers, M cells are specialized antigen-delivery cells for the immune system in organs like the intestine and lungs. They play a key role in the development of the body’s immune system. The researchers at the Weizmann Institute of Science in Israel, led by Jakub Abramson, initiated the mouse study on the thymic epithelium before contacting Lo, whose research interests include understanding how M cells in the gut and airways work to build our immune system.  “I have been working on these cells for several years, so when the Israeli team contacted me, I was intrigued,” Lo said. “I learned this group had been doing studies on the cellular architecture of stromal cells — cells that make up certain types of connective tissue — in the thymus and, using a new advanced method, had discovered a population of cells much like the M cells we see in the gut and airways. In my own research, I had simply never thought to look for M cells in the thymus.” Fortuitously for the Israeli scientists, Del Castillo, under Lo’s guidance, had been studying mucosal tissues — tissues that line some of the body’s canals and organs — in mice in the lab and was able to answer several questions, such as where in the thymus the newly discovered cells are located and what they are doing there.  The Unique Nature of Thymic M Cells “These particular M cells are limited to a specific region in the thymus and have unique associations with different cell types and functions,” Del Castillo said. “Questions these cells have already prompted include how similar are they to M cells elsewhere in the body and what is different about where they have been found.” Lo explained that for many years the thymus has been a tissue of interest to immunologists because most of the immune system’s development is centered and dependent on the thymus.  “It’s still an ongoing deep puzzle that continues to attract interest,” he said. “The thymus offers clues to how the immune system got its start. This complicated organ, with so many different stromal cell types and interactions, is responsible for producing lymphocytes that protect us from infection.” David Lo (left) is seen here with Diana Del Castillo. Credit: Lo lab, UC Riverside According to Lo, the newly discovered M cells are extremely similar to the M cells seen in the gut and airways.  “But the thymic M cells have different developmental origins, which is an interesting puzzle in itself,” he said. “After they develop, they look very much like the ones we have been studying in the gut. As we know, M cells capture viruses and bugs that enter the airways and hand them off to the immune system, which then responds to the infectious agents. Are the M cells doing the same thing in the thymus in terms of organization and function? That’s what we would like to know.” Exploring the Function of Thymic M Cells Del Castillo, who is working toward her doctoral degree in biomedical sciences, used genetically engineered mice to tackle the questions from the Israeli researchers.  “We found the new cells were scattered in the medullary region of the thymus,” she said. “This has interesting implications in terms of the role and compartmentalization of the thymus, such as how these cells may function to regulate lymphocyte training within this organ.” Lo and Del Castillo were surprised to find that many steps involved in shaping an immune response in various parts of the body seem to be echoed in the thymus. “It is fascinating to see that many of these early cell interactions and development we have studied closely in the peripheral immune system take place in the thymus,” Lo said. “We had not anticipated to see these interactions here. It’s like watching a short video in the thymus about what is happening big-scale out in the periphery.” The thymus also ensures that lymphocytes do not accidentally attack our own tissues; the thymic medulla is where these decisions are made, the UCR scientists said. “The newly discovered M cells are part of this decision-making process,” Del Castillo said. “The production of antibodies in the peripheral immune system to fight off infectious organisms involves several steps and many cells interacting with each other. What is fascinating is that some of these interactions are recapitulated in the early stages of the development of the thymic M cells.” According to Lo, the thymic M cells could be seen as being trained to function later, when needed, in the periphery in such a way that they are ready to communicate and interact with other cells. “The thymus is complicated because it creates a whole functional immune system and repertoire, and we know many component parts play a role in its performance,” he said. “We didn’t expect M cells to even show up in the thymus. This is, therefore, a satisfying discovery because it is so clearly connected to similar processes happening in the gut and airways, which is where 60-70% of our infectious agents enter our bodies.”  Reference: “Thymic mimetic cells function beyond self-tolerance” by Tal Givony, Dena Leshkowitz, Diana Del Castillo, Shir Nevo, Noam Kadouri, Bareket Dassa, Yael Gruper, Razi Khalaila, Osher Ben-Nun, Tom Gome, Jan Dobeš, Shifra Ben-Dor, Merav Kedmi, Hadas Keren-Shaul, Rebecca Heffner-Krausz, Ziv Porat, Ofra Golani, Yoseph Addadi, Ori Brenner, David D.

A transplanted pseudoislet made from CD63hi beta cells. Credit: Weill Cornell Medicine High-functioning beta cells identified by CD63 expression play a critical role in insulin production. Their loss correlates with type 2 diabetes, offering insights for advanced transplant therapies. Multiple types of beta cells produce insulin in the pancreas, helping to balance blood sugar levels. A recent study conducted by Weill Cornell Medicine investigators has revealed that the loss of a highly productive type of beta cell in the pancreas could potentially contribute to the development of diabetes. The study, recently published in Nature Cell Biology, was led by Dr. James Lo, an associate professor of medicine at Weill Cornell Medicine, examined gene expression in individual beta cells from mice to identify the number of different beta cell types in the pancreas. The research team found four distinct types of beta cells, with one group, known as cluster 1, standing out due to their superior insulin production and sugar metabolism capabilities. The study also revealed that the loss of this particular type of beta cell may be linked to the development of type 2 diabetes. “Before this, people thought a beta cell was a beta cell, and they just counted total beta cells,” said Dr. Lo, who is also a member of the Weill Center for Metabolic Health and the Cardiovascular Research Institute at Weill Cornell Medicine and a cardiologist at NewYork-Presbyterian/Weill Cornell Medical Center. “But this study tells us it might be important to subtype the beta cells and that we need study the role of these special cluster 1 beta cells in diabetes.” Drs. Doron Betel, Jingli Cao, Geoffrey Pitt and Shuibing Chen at Weill Cornell Medicine teamed up with Dr. Lo to carry out the study. Unique Gene Expression and Insulin Production The investigators used a technique called single-cell transcriptomics to measure all the genes expressed in individual mouse beta cells and then used that information to group them into four types. The cluster 1 beta cells had a unique gene expression signature that included high expression of genes that help cellular powerhouses called mitochondria to break down sugar and power them to secrete more insulin. Additionally, they could distinguish the cluster 1 beta cells from the other beta cell types by its high expression of the CD63 gene, which enabled them to use the CD63 protein as a marker for this specific beta cell type. “CD63 expression provided us a way to identify the cells without destroying them and allowed us to study the live cells,” he said. When the team looked at both human and mouse beta cells, they found that cluster 1 beta cells with high CD63 gene expression produce more insulin in response to sugar than the three other types of beta cells with low CD63 expression. “They are very high-functioning beta cells,” Dr. Lo said. “We think they may carry the bulk of the workload of producing insulin, so their loss might have profound impacts.” Impact of Cluster 1 Beta Cell Loss on Diabetes In mice fed an obesity-inducing, high-fat diet and mice with type 2 diabetes, the numbers of these insulin-producing-powerhouse beta cells decreased. “Because the numbers of cluster 1/high CD63 cells went down, you may have less insulin production, which may play a major role in diabetes development,” he said. Transplanting beta cells with high CD63 production into mice with type 2 diabetes restored their blood sugar levels to normal. But removing the transplanted cells caused high blood sugar levels to return. Transplanting low CD63 production beta cells into the mice didn’t restore blood sugar to normal levels. The transplanted low CD63 beta cells instead appeared dysfunctional. Beta Cell Transplants in Diabetes Treatment The discovery may have important implications for the use of beta cell transplants to treat diabetes, Dr. Lo said. For example, it may be better to transplant only high CD63- beta cells. He noted that it might also be possible to transplant fewer of these highly productive cells. Dr. Lo’s team also found that humans with type 2 diabetes had lower levels of high CD63 beta cells compared to those without diabetes. Next, Dr. Lo and his colleagues would like to find out what happens to the high CD63-producing beta cells in mice with diabetes and how to keep them from disappearing. “If we can figure out how to keep them around longer, surviving and functional, that could lead to better ways to treat or prevent type 2 diabetes,” he said. They would also like to study how existing diabetes treatments affect all types of beta cells. GLP-1 agonists, which help increase the release of insulin in people with diabetes, interact with high and low CD63-producing beta cells. “Our study also shows that GLP-1 agonists might also be a way to get the low CD63-producing beta cells to work better,” Dr. Lo said.
