Argentine Ant (Linepithema humile). Detecting environmental DNA of invasive ant species in soil samples. Researchers have successfully detected the environmental DNA (eDNA)[1] of the Argentine ant[2] in surface soil samples from sites on Kobe’s Port Island and in Kyoto’s Fushimi District, two areas that have a long history of destruction caused by this invasive species. The research group included then graduate student YASASHIMOTO Tetsu and Associate Professor MINAMOTO Toshifumi of Kobe University’s Graduate School of Human Development and Environment, Visiting Professor OZAKI Mamiko of the Graduate School of Engineering, and NAKAJIMA Satoko, formally of the Kyoto Prefectural Institute of Public Health and Environment. This method can be used to enable scientists to easily gain an accurate understanding of the habitat distribution and hotspots for globally invasive ant species[3], such as the fire ant, which cause significant damage. Combining this method with pest control plans against invasive ant species will contribute towards the formulation of targeted measures and successful elimination results. These research results are due to be published in Scientific Reports today (May 26, 2021). Main points Invasive ant species are causing serious damage worldwide. Early detection and rapid elimination is essential for controlling their populations. However, current pest control methods involve a series of direct detection techniques (such as visual observation, capture, classification, elimination, follow-up observation and evaluation), which require specialist knowledge, labor and time. This is inefficient considering the widespread damage caused worldwide by these invasive species. By focusing on one species that is difficult to eradicate (the Argentine ant), the group demonstrated that eDNA analysis can provide a useful tool for observing and evaluating the invasion, establishment and proliferation of invasive ant species. The research group developed an Argentine ant-specific real-time PCR assay. Using this new assay, they successfully and highly accurately detected eDNA originating from this species in surface samples collected from invasion sites. The researchers compared the presence of eDNA with the last decade of pest control records. They demonstrated the efficiency of eDNA analysis for monitoring populations of the target species and reported for the first time that this method could lead to rapid improvements in the accuracy and effectiveness of invasive ant extermination.

Research Background In the midst of globalization, the transport of goods and commodities between nations is increasing. Consequently, the arrival, subsequent establishment and widespread proliferation of invasive ant species that are inadvertently transported to other countries has developed into a worldwide problem. In Japan, Argentine ant (Figure 1A) colonies continue to proliferate widely, and the invasion and establishment of highly poisonous fire ant populations have also been reported. The research group chose two areas that have a long history of damage caused by the Argentine ant; 1. Kyoto’s Fushimi district and 2. Kobe’s Port Island. 1. Fushimi has continuously used insecticide measures for almost 10 years, and has had consistent success in suppressing Argentine ant populations in built-up areas. 2. Although the Argentine ant first invaded Kobe over 20 years ago, the situation has yet to change for the better. In cases like 1, where insecticide-based methods have been carried out for a long period of time, it is difficult to stop the usage of insecticide on a non-scientific basis, even though this presents a problem from the perspective of conserving the natural environment and ecosystem. In cases like 2, there are no pest control plans in place because the extent of the species’ distribution is not readily understood.

Environmental DNA analysis is a biological monitoring method that was introduced into the fields of ecology and conservation biology around 2008. It has brought about revolutionary changes in the conduction of biological surveys, especially in aquatic environments. It is hoped that applying this technique to surface soil samples instead of water samples will play a key role in eliminating invasive ants, providing a breakthrough solution to this problem. Research Methodology and Findings Argentine ant-specific DNA assay The researchers designed a real-time PCR assay specific to the Argentine ant and experimentally confirmed the specificity of the assay. The researchers then performed the following experiments using this method. Selection of surface sample sites and their respective pest control histories Surface samples were collected from a total of four sites (FM-1 to 4) in the Fushimi district of Kyoto in order to test them for the eDNA of the Argentine ant, as shown in Figure 1B. The characteristics of efforts to control invasive ant species over the past decade are different for each site (Figure 2). Detecting the eDNA of Argentine ants using surface soil samples Environmental DNA from the Argentine ant was found in the samples from the FM-1 and FM-2 sites, where their presence had previously been confirmed by traditional bait trap surveys. However, eDNA from this invasive species was not detected in the samples taken from sites FM-3 and FM-4. These results did not contradict those obtained using the bait trap method, suggesting that eDNA analysis can be considered more accurate than surveys based on visual observations (Table 1). In addition, native ant species were observed at each of the survey sites. At sites FM-1 and 2, where Argentine ant eDNA was detected, 7 and 3 native species were observed, whereas at sites FM-3 and 4, where the invasive ant’s DNA was not detected, 15 and 10 native species were found respectively. This indicates that the invasive species may be driving out native ant species. Table 1: Comparison of Argentine ant detection methods (eDNA analysis, trap method, and visual observation). Three environmental DNA samples each were taken from Sites FM-1 to 3 and one sample was taken from FM-4. Detection tests were carried out on each sample with three replications. Credit: Minamoto et al., Scientific Reports, 2021. Conclusions and Further Developments 1. By comparing and analyzing the results of environmental DNA analysis of various ant species with the habitat data of Argentine ant and native ant species accumulated over the years, a method for estimating ant habitat by environmental DNA can be developed for practical use. In this way, eDNA could provide a scientific basis from which to reconsider previous ineffective pest control methods and to eradicate issues relating to the continuance of pest control and confirming extermination. 2. The environmental DNA method is a fundamental, all-purpose technique, which enables further research into other invasive ant species, such as fire ants, to be conducted in the same way. 3. A policy model for the control of invasive species, based on the Sustainable Development Goal (SDG) to ‘Conserve and restore terrestrial ecosystems and halt biodiversity loss’, can be drawn up and implemented, beginning with invasive ant species (including Argentine ant and fire ant). Glossary Environmental DNA (eDNA): This is DNA originating from organisms that is found in the environment, such as in the water or on the ground. Environmental DNA analysis allows researchers to comprehensively identify species that reside in an area, even if they no longer live there. This in turn enables them to estimate and gain an understanding of the target species’ distribution. Environmental DNA surveys are used in a wide range of research fields, including species conservation, ecology, taxonomy, microbiology and palaeontology. Argentine ant (Linepithema humile): The Argentine ant is part of the Dolichoderinae subfamily and belongs to the Hymenoptera order. It originated in South America. The IUCN (International Union for Conservation of Nature and Natural Resources) ranks it as one of the world’s worst 100 invasive species. It is also designated as one of Japan’s worst 100 invasive species. It was first found in Japan in 1993 in Hatsukaichi City (Hiroshima Prefecture) and has since been reported in 11 prefectures. It is a very difficult species to eradicate once it has invaded an area, as the ant establish supercolonies with multiple queens. Invasive ant species: These species have spread beyond their country of origin and have established themselves in countries worldwide. They invade native species’ habitats, as well as the dwellings of people and livestock; posing a threat to living environments, in addition to health and safety. These invasive ant species drive out and eradicate the former occupants of an area, which leads to a loss of biodiversity and ecosystem destruction.

New research reveals microglia, immune cells in the brain, are critical “support staff,” tending the vessels and even regulating blood flow. University of Virginia School of Medicine researchers have revealed a vital but previously unknown role for immune cells that protect the brain from disease and injury: The cells, known as microglia, also help regulate blood flow and maintain the brain’s critical blood vessels. In addition to revealing a new aspect of human biology, the findings may prove important in cognitive decline, dementia and stroke, among other conditions linked to diseases of the brain’s small vessels, the researchers say. “Precise blood vessel function is critical to accommodate the extreme energy demands of the brain for normal brain function,” said UVA’s Ukpong B. Eyo, PhD, of UVA’s Department of Neuroscience, the UVA Brain Institute, and UVA’s Center for Brain Immunology and Glia (BIG). “These findings suggest previously unknown roles for these brain cells in the proper maintenance of blood delivery to the brain and provide novel opportunities to intervene in contexts where blood perfusion to the brain is impaired.” The Role of Microglia Scientists have known that microglia play many important roles in the brain. For example, the cells police the natural blood-brain barrier that protects the organ from harmful germs in the bloodstream. Microglia also facilitate the formation of the brain’s complex network of blood vessels during development. And they are known to be important in many diseases. In Alzheimer’s disease, for example, recent work suggests that the loss of the immune cells is thought to increase harmful plaque buildup in the brain. Scientists have been unsure, however, what role microglia play in maintaining blood vessels in a normal, healthy brain. The new research from Eyo and his colleagues reveals that the cells are critical support staff, tending the vessels and even regulating blood flow. “Precise blood vessel function is critical to accommodate the extreme energy demands of the brain for normal brain function,” said Ukpong B. Eyo, PhD, of UVA’s Department of Neuroscience, the UVA Brain Institute and UVA’s Center for Brain Immunology and Glia (BIG). “These findings suggest previously unknown roles for these brain cells in the proper maintenance of blood delivery to the brain and provide novel opportunities to intervene in contexts where blood perfusion to the brain is impaired.” Credit: Dan Addison, UVA Communications The UVA researchers identified microglia associating with the brain’s capillaries, determined what the immune cells do there and revealed what controls those interactions. Among the cells’ important responsibilities is helping to regulate the diameter of the capillaries and possibly restricting or increasing blood flow as needed. “Researchers have been studying these cells in the living brain for over two decades but this is the first time we are able to get an idea of these mechanisms of microglia-blood vessel interaction,” said Eyo, a top expert on microglia. “It’s an exciting time to be the first to make these findings here at UVA.” The researchers believe their new findings could have significant implications for diseases that affect the small vessels of the brain. These conditions are thought to contribute to strokes, Alzheimer’s, loss of balance, and mental decline, among other serious health problems. “We are currently expanding this research into an Alzheimer’s disease context in rodents to investigate whether the novel phenomenon is altered in mouse models of the disease and determine whether we could target the mechanisms we uncovered to improve known deficits in blood flow in such a mouse model of Alzheimer’s,” Eyo said. “Our hope is that these findings in the lab could translate into new therapies in the clinic that would improve outcomes for patients.” Reference: “Capillary-associated microglia regulate vascular structure and function through PANX1-P2RY12 coupling in mice” by Kanchan Bisht, Kenneth A.

Illustration of the RecA filament. Credit: David Goodsell How the cell can mend broken DNA using another DNA copy as template has puzzled researchers for years. How is it possible to find the correct sequences in the busy interior of the cell? Researchers from Uppsala University have now discovered the solution; it is easier to find a rope than a ball if you are blindfolded. When a DNA molecule breaks in two, the fate of the cell is threatened. From the perspective of a bacterium, fixing the break quickly is a matter of life and death. But to mend the DNA without introducing mistakes in the sequence is challenging; the repair machinery needs to find a template. The process of healing broken DNA using a template from a sister chromosome is known as homologous recombination and is well described in the literature. However, the description usually disregards the daunting task of finding the matching template among all the other genome sequences. The chromosome is a complex structure with several million base pairs of genetic code and it is quite clear that simple diffusion in 3D would not be sufficiently fast by a long shot. But then, how is it done? This has been the mystery of homologous recombination for 50 years. From previous studies, it is clear that the molecule RecA is involved and important in the search process, but, up until now, this has been the limit of our understanding of this process. Now, a group of Uppsala researchers headed by Professor Johan Elf has finally found the solution to this search enigma. In a study that is published in Nature, they use a CRISPR-based technique to make controlled DNA breaks in bacteria. By growing the cells in a microfluidic culture chip and tracking labeled RecA molecules with fluorescence microscopy, the researchers can image the homologous recombination process from start to finish. “The microfluidic culture chip allows us to follow the fate of thousands of individual bacteria simultaneously and to control CRISPR-induced DNA breaks in time. It is very precise, almost like having a pair of tiny DNA scissors,” says Jakub Wiktor, one of the researchers behind the study. The label on RecA together with fluorescent markers on the DNA allows the researchers to follow every step of the process accurately; for example, they conclude that the whole repair is finished in 15 minutes, on average, and that the template is located in about nine. Using microscopy, Elf and his team investigate the fate of the break site and its homologous copy in real-time. They also find that the cell responds by rearranging RecA to form thin filaments that span the length of the cell. “We can see the formation of a thin, flexible structure that protrudes from the break site just after the DNA damage. Since the DNA ends are incorporated into this fiber, it is sufficient that any part of the filament finds the precious template and thus the search is theoretically reduced from three to two dimensions. Our model suggests that this is the key to fast and successful homology repair,” says Arvid Gynnå, who has worked on the project throughout his PhD studies. Going from a 3D to a 2D search is indeed a considerable improvement regarding the probability of finding the homologous sequence quickly enough, or in fact, at all. As the Japanese mathematician, Shizuo Kakutani put it: “A drunk man will find his way home, but a drunk bird may be lost forever”. With these words, he tried to explain a curious fact; an object that explores a 2D surface by a random walk will sooner or later find its way back to its starting point while in a 3D space, it is likely that it will never return “home”. The Uppsala researchers performed their study in the model organism E. coli, but the process of homology repair is nearly identical for higher organisms such as ourselves, or doves for that matter. DNA damage occurs frequently in our bodies, and without the ability to heal broken DNA, we would be extremely vulnerable to, for example, UV light and reactive oxygen species, and more likely to develop cancer. In fact, most oncogenes are related to DNA repair and the new mechanistic insights might help us understand the causes of tumor growth.
