Infection of human intestinal epithelial cells by Salmonella Typhimurium during spaceflight aboard NASA Space Shuttle mission STS-131. Credit: Graphic by Shireen Dooling for the Biodesign Institute at Arizona State University Astronauts face many challenges to their health, due to the exceptional conditions of spaceflight. Among these are a variety of infectious microbes that can attack their suppressed immune systems. Now, in the first study of its kind, Cheryl Nickerson, lead author Jennifer Barrila, and their colleagues describe the infection of human cells by the intestinal pathogen Salmonella Typhimurium during spaceflight. They show how the microgravity environment of spaceflight changes the molecular profile of human intestinal cells and how these expression patterns are further changed in response to infection. In another first, the researchers were also able to detect molecular changes in the bacterial pathogen while inside the infected host cells. The results offer fresh insights into the infection process and may lead to novel methods for combatting invasive pathogens during spaceflight and under less exotic conditions here on earth. The results of their efforts appear in the current issue of the Nature Publishing Group journal npj Microgravity. Mission control In the study, human intestinal epithelial cells were cultured aboard Space Shuttle mission STS-131, where a subset of the cultures were either infected with Salmonella or remained as uninfected controls. The new research uncovered global alterations in RNA and protein expression in human cells and RNA expression in bacterial cells compared with ground-based control samples and reinforces the team’s previous findings that spaceflight can increase infectious disease potential. Cheryl Nickerson is a researcher in the Biodesign Center for Fundamental and Applied Microbiomics and a professor in the School of Life Sciences at ASU. Credit: The Biodesign Institute at Arizona State University Nickerson and Barrila, researchers in the Biodesign Center for Fundamental and Applied Microbiomics, along with their colleagues, have been using spaceflight as a unique experimental tool to study how changes in physical forces, like those associated with the microgravity environment, can alter the responses of both the host and pathogen during infection. Nickerson is also a professor in the School of Life Sciences at ASU. In an earlier series of pioneering spaceflight and ground-based spaceflight analogue studies, Nickerson’s team demonstrated that the spaceflight environment can intensify the disease-causing properties or virulence of pathogenic organisms like Salmonella in ways that were not observed when the same organism was cultured under conventional conditions in the laboratory. The studies provided clues as to the underlying mechanisms of the heightened virulence and how it might be tamed or outwitted. However, these studies were done when only the Salmonella were grown in spaceflight and the infections were done when the bacteria were returned to Earth. “We appreciate the opportunity that NASA provided our team to study the entire infection process in spaceflight, which is providing new insight into the mechanobiology of infectious disease that can be used to protect astronaut health and mitigate infectious disease risks,” Nickerson says of the new study. “This becomes increasingly important as we transition to longer human exploration missions that are further away from our planet.” Probing a familiar adversary Salmonella strains known to infect humans continue to ravage society, as they have since antiquity, causing around 1.35 million foodborne infections, 26,500 hospitalizations, and 420 deaths in the United States every year, according to the Centers for Disease Control. The pathogen enters the human body through the ingestion of contaminated food and water, where it attaches and invades into intestinal tissue. The infection process is a dynamic dance between host and microbe, its rhythm dictated by the biological and physical cues present in the tissue’s environment. Despite decades of intensive research, scientists still have much to learn about the subtleties of pathogenic infection of human cells. Invasive bacteria like Salmonella have evolved sophisticated countermeasures to human defenses, allowing them to flourish under hostile conditions in the human stomach and intestine to stealthily evade the immune system, making them highly effective agents of disease. The issue is of particular medical concern for astronauts during spaceflight missions. Their immune systems and gastrointestinal function are altered by the rigors of space travel, while the effects of low gravity and other variables of the spaceflight environment can intensify the disease-causing properties of hitchhiking microbes, like Salmonella. This combination of factors poses unique risks for space travelers working hundreds of miles above the earth—far removed from hospitals and appropriate medical care. As technology advances, it is expected that space travel will become more frequent—for space exploration, life sciences research, and even as a leisure activity (for those who can afford it). Further, extended missions with human crews are on the horizon for NASA and perhaps space-voyaging companies like SpaceX, including trips to the Moon and Mars. A failure to keep bacterial infections at bay could have dire consequences. Hide and Seq In the current study, human intestinal epithelial cells, the prime target for invasive Salmonella bacteria, were infected with Salmonella during spaceflight. The researchers were keen to examine how the spaceflight setting affected the transcription of human and bacterial DNA into RNA, as well as the expression of the resulting suite of human proteins produced from the RNA code, products of a process known as translation. The research involved the close examination of transcriptional profiles of both the pathogenic Salmonella and the human cells they attack, as well as the protein expression profiles of the human cells to gauge the effects of the spaceflight environment on the host-pathogen dynamic. Jennifer Barrila, lead author of the new study, is a researcher in the Biodesign Center for Fundamental and Applied Microbiomics. Credit: The Biodesign Institute at Arizona State University To accomplish this, researchers used a revolutionary method known as dual RNA-Seq, which applied deep sequencing technology to enable their evaluation of host and pathogen behavior under microgravity during the infection process and permitted a comparison with the team’s previous experiments conducted aboard the Space Shuttle. The host and pathogen data recovered from spaceflight experiments were compared with those obtained when cells were grown on Earth in identical hardware and culture conditions (e.g., media, temperature). Earth and sky Earlier studies by Nickerson and her colleagues demonstrated that ground-based spaceflight analog cultures of Salmonella exhibited global changes in their transcriptional and proteomic (protein) expression, heightened virulence, and improved stress resistance—findings similar to those produced during their experiments on STS-115 and STS-123 Space Shuttle missions. However, these previous spaceflight studies were done when only the Salmonella were grown in spaceflight and the infections were done when the bacteria were returned to Earth. In contrast, the new study explores for the first time, a co-culture of human cells and pathogen during spaceflight, providing a unique window into the infection process. The experiment, called STL-IMMUNE, was part of the Space Tissue Loss payload carried aboard STS-131, one of the last four missions of the Space Shuttle prior to its retirement. The human intestinal epithelial cells were launched into space (or maintained in a laboratory at the Kennedy Space Center for ground controls) in three-dimensional (3-D) tissue culture systems called hollow fiber bioreactors. The hollow fiber bioreactors each contained hundreds of tiny, porous straw-like fibers coated with collagen upon which the intestinal cells attached and grew. These bioreactors were maintained in the Cell Culture Module, an automated hardware system that pumped warm, oxygenated cell culture media through the tiny fibers to keep the cells healthy and growing until they were ready for infection with Salmonella. Once in orbit, astronauts aboard STS-131 activated the hardware. Eleven days later, S. Typhimurium cells were automatically injected into a subset of the hollow fiber bioreactors, where they encountered their target—a layer of human epithelial cells. The RNA-Seq and proteomic profiles showed significant differences between uninfected intestinal epithelial cultures in space vs those on Earth. These changes involved major proteins important for cell structure as well as genes important for maintaining the intestinal epithelial barrier, cell differentiation, proliferation, wound healing, and cancer. Based on their profiles, uninfected cells exposed to spaceflight may display a reduced capacity for proliferation, relative to ground control cultures. Infections far from home Human intestinal epithelial cells act as critical sentinels of innate immune function. The results of the experiment showed that spaceflight can cause global changes to the transcriptome and proteome of human epithelial cells, both infected and uninfected. During spaceflight, 27 RNA transcripts were uniquely altered in intestinal cells in response to infection, once again establishing the unique influence of the spaceflight environment on the host-pathogen interaction. The researchers also observed 35 transcripts that were commonly altered in both space-based and ground-based cells, with 28 genes regulated in the same direction. These findings confirmed that at least a subset of the infection biosignatures that are known to occur on Earth also occur during spaceflight. Compared with uninfected controls, infected cells in both environments displayed gene regulation associated with inflammation, a signature effect of Salmonella infection. Bacterial transcripts were also simultaneously detected within the infected host cells and indicated upregulation of genes associated with pathogenesis, including antibiotic resistance and stress responses. The findings help pave the way for improved efforts to safeguard astronaut health, perhaps through the use of nutritional supplements or probiotic microbes. Ongoing studies of this kind, to be performed aboard the International Space Station and other space habitats, should further illuminate the many mysteries associated with pathogenic infection and the broad range of human illnesses for which they are responsible. “Before we began this study, we had extensive data showing that spaceflight completely reprogrammed Salmonella at every level to become a better pathogen,” Barrila says. “Separately, we knew that spaceflight also impacted several important structural and functional features of human cells that Salmonella normally exploits during infections on Earth. However, there was no data showing what would happen when both cell types met in the microgravity environment during infection. Our study indicates that there are some pretty big changes in the molecular landscape of the intestinal epithelium in response to spaceflight, and this global landscape appears to be further altered during infection with Salmonella.” Reference: “Evaluating the effect of spaceflight on the host–pathogen interaction between human intestinal epithelial cells and Salmonella Typhimurium” by Jennifer Barrila, Shameema F.

DOI: 10.1038/s41526-021-00136-w This work was done in collaboration with scientists from the NASA Johnson Space Center, NASA Ames Research Center, Japanese Aerospace Exploration Agency (JAXA), Tissue Genesis, and the Department of Defense (DoD). Researchers have discovered previously overlooked non-coded DNA, which may explain why our brains function differently from chimpanzees’, despite our genetic similarities. Our DNA is very similar to that of the chimpanzee, which in evolutionary terms is our closest living relative. Stem cell researchers at Lund University in Sweden have now found a previously overlooked part of our DNA, so-called non-coded DNA, that appears to contribute to a difference which, despite all our similarities, may explain why our brains work differently. The study is published in the journal Cell Stem Cell. The chimpanzee is our closest living relative in evolutionary terms and research suggests our kinship derives from a common ancestor. About five to six million years ago, our evolutionary paths separated, leading to the chimpanzee of today, and Homo Sapiens, humankind in the 21st century. In a new study, stem cell researchers at Lund examined what it is in our DNA that makes human and chimpanzee brains different – and they have found answers. “Instead of studying living humans and chimpanzees, we used stem cells grown in a lab. The stem cells were reprogrammed from skin cells by our partners in Germany, the USA and Japan. Then we examined the stem cells that we had developed into brain cells,” explains Johan Jakobsson, professor of neuroscience at Lund University, who led the study. Using the stem cells, the researchers specifically grew brain cells from humans and chimpanzees and compared the two cell types. The researchers then found that humans and chimpanzees use a part of their DNA in different ways, which appears to play a considerable role in the development of our brains. “The part of our DNA identified as different was unexpected. It was a so-called structural variant of DNA that were previously called “junk DNA,” a long repetitive DNA string which has long been deemed to have no function. Previously, researchers have looked for answers in the part of the DNA where the protein-producing genes are – which only makes up about two percent of our entire DNA – and examined the proteins themselves to find examples of differences.” The new findings thus indicate that the differences appear to lie outside the protein-coding genes in what has been labeled as “junk DNA,” which was thought to have no function and constitutes the majority of our DNA. “This suggests that the basis for the human brain’s evolution is genetic mechanisms that are probably a lot more complex than previously thought, as it was supposed that the answer was in those two percent of the genetic DNA. Our results indicate that what has been significant for the brain’s development is instead perhaps hidden in the overlooked 98 percent, which appears to be important. This is a surprising finding.” The stem cell technique used by the researchers in Lund is revolutionary and has enabled this type of research. The technique was recognized by the 2012 Nobel Prize in Physiology or Medicine. It was the Japanese researcher Shinya Yamanaka who discovered that specialized cells can be reprogrammed and developed into all types of body tissue. And in the Lund researchers’ case, into brain cells. Without this technique, it would not have been possible to study the differences between humans and chimpanzees using ethically defensible methods. Why did the researchers want to investigate the difference between humans and chimpanzees? “I believe that the brain is the key to understanding what it is that makes humans human. How did it come about that humans can use their brains in such a way that they can build societies, educate their children, and develop advanced technology? It is fascinating!” Johan Jakobsson believes that in the future the new findings may also contribute to genetically-based answers to questions about psychiatric disorders, such as schizophrenia, a disorder that appears to be unique to humans. “But there is a long way to go before we reach that point, as instead of carrying out further research on the two percent of coded DNA, we may now be forced to delve deeper into all 100 percent – a considerably more complicated task for research,” he concludes.

DOI: 10.1016/j.stem.2021.09.008 A recent study uncovers the factors influencing animal size changes over time, identifying three evolutionary patterns based on competition and environmental pressures, providing clarity on the inconsistencies in fossil records. Credit: SciTechDaily.com New research reveals key factors behind the changing sizes of certain animals over time, challenging traditional evolutionary theories with its findings on species’ size variations. The mystery behind why Alaskan horses, cryptodiran turtles, and island lizards shrunk over time may have been solved in a new study. The new theoretical research proposes that animal size over time depends on two key ecological factors: the intensity of direct competition for resources between species, and the risk of extinction from the environment. Study Findings and Ecological Factors Using computer models simulating evolution, the study, published today (Thursday, January 18) in the journal Communications Biology, identifies why some species gradually get smaller, as indicated by fossil records. Dr. Shovonlal Roy, an ecosystem modeler from the University of Reading who led the research, said: “Just like how we try to adapt to hot or cold weather depending on where we live, our research shows animal size can get bigger or smaller over long periods depending on the habitat or environment. “In places and times where there’s lots of competition between different species for food and shelter, animal sizes often get smaller as the species spread out and adapt to the distribution of resources and competitors. For example, small horses that lived in Alaska during the Ice Age rapidly shrank due to changes in the climate and vegetation. “Where direct competition is less, sizes tend to get bigger, even though being really big and few in number can make animals more vulnerable to dying out – such as what happened with the dinosaurs. “Changes in ecological factors help explain why fossil records shows such confusing mixes of size evolution patterns, with some lineages shrinking over time and others growing.” Cope’s Rule The research team carried out their study by challenging the contradictions fossil evidence posed to “Cope’s rule.” Cope’s rule refers to the tendency for certain animal groups to evolve larger body sizes over thousands and millions of years. The rule is named after Edward Cope, a 19th-century paleontologist who was credited to have first noticed this pattern in the fossil record. For example, early horse ancestors were small dog-sized animals that increased in size over evolutionary time, ultimately producing the modern horse. However, fossil evidence shows remarkably conflicting trends, with increased size in some groups but decreased size in others. Evolutionary Pressure Using computer models simulating evolution, the study identified three distinct patterns of body-size change emerging under different conditions: Gradual size increase over time: This happens when competition between species is determined mostly by their relative body sizes rather than niche differences. For example, several genera of marine animal species (e.g. invertebrates) gradually increased in size over millions of years. Size increase followed by extinctions: Here the largest animals recurrently go extinct, opening opportunities for other species to take their place and evolve even bigger bodies, continuing the cycle. Mass extinctions hit large-bodied apex predators hardest. Very large mammals and birds are particularly vulnerable to extinction – for example, dinosaurs and giant flying reptiles. Gradual size decrease over time: The simulations also predicted the opposite of Cope’s rule: species shrinking over time. This happens when competition is high and there is a degree of overlap in habitat and resource use. As species evolve apart into distinct niches, they face evolutionary pressure to reduce in size. Decline in size was previously reported for vertebrates, bony fish, cryptodiran turtles, Alaskan Pleistocene horses, and island lizards.
