Researchers have gained new insight into the biological processes of a chytrid fungus responsible for a deadly skin infection devastating frog populations worldwide. Bd’s actin structures likely play roles in causing skin disease threatening amphibians worldwide. Researchers at the University of Massachusetts Amherst have gained new insight into the biological processes of a chytrid fungus responsible for a deadly skin infection devastating frog populations worldwide. Led by cell biologist Lillian Fritz-Laylin, the team describes in a paper published today (February 8, 2021) in Current Biology how the actin networks of Batrachochytrium dendrobatidis (Bd) also serve as an “evolutionary Rosetta Stone,” revealing the loss of cytoskeletal complexity in the fungal kingdom. Research associate Sarah Prostak initially wrote what later became the Current Biology paper for her undergraduate honors biology thesis at the University of Massachusetts Amherst. Credit: UMass Amherst “Fungi and animals seem so different, but they are actually pretty closely related,” says Fritz-Laylin, whose lab studies how cells move, which is a central activity in the progression and prevention of many human diseases. “This project, the work of Sarah Prostak in my lab, shows that during early fungal evolution, fungi probably had cells that looked something like our cells, and which could crawl around like our cells do.” Chytrids including Bd encompass more than 1,000 species of fungi deep on the phylogenetic, or evolutionary, tree. The researchers used chytrids, which share features of animal cells that have been lost in yeast and other fungi, to explore the evolution of actin cytoskeleton, which helps cells keep their shape and organization and carry out movement, division and other crucial functions. Prostak, a research associate in Fritz-Laylin’s lab, is the lead author of the paper, which she initially wrote as her undergraduate honors biology thesis, the expanded and finished the research after graduation. Other authors are Margaret Titus, professor of genetics, cell biology and development at the University of Minnesota, and Kristyn Robinson, a UMass Amherst Ph.D. candidate in Fritz-Laylin’s lab. “Bd is more closely related to animal cells than more typically studied fungi so it can tell us a lot about the animal lineage and the fungal lineage and can also provide a lot of insight into human actin networks,” Prostak says. “We can use it to study animal-like regulation in a similar system rather than actually studying it in animal cells, which is very complicated because animal cells have so many actin regulators.” Lillian Fritz-Laylin is a professor of biology in the College of Natural Sciences at the University of Massachusetts Amherst. Credit: UMass Amherst The research team used a combination of genomics and fluorescence microscopy to show that chytrids’ actin cytoskeleton has features of both animal cells and yeast. “How these complex actin regulatory networks evolved and diversified remain key questions in both evolutionary and cell biology,” the paper states. The biologists explored the two developmental stages in Bd’s life cycle. In the first stage, Bd zoospores swim with a flagellum and build actin structures similar to those of animal cells, including pseudopods that propel the organisms forward. In the reproductive stage, Bd sporangia assemble actin shells, as well as actin patches, which are similar to those of yeast. The disease chytridiomycosis, caused by Bd, ravages the skin of frogs, toads and other amphibians, eventually leading to heart failure after throwing off fluid regulation. This disease has been attributed to huge losses of biodiversity, including dozens of presumed population declines and extinctions over the past 50 years, though exactly how many species have been affected by this disease has been subject to debate. The UMass Amherst biologists say Bd’s actin structures they observed likely play important roles in causing the disease. “This model suggests that actin networks underlie the motility and rapid growth that are key to the pathology and pathogenicity of Bd,” the paper concludes. Prostak, an animal lover drawn to Fritz-Laylin’s lab because of its focus on pathogens, hopes their research advancing the knowledge about Bd will lead to measures that slow the deadly damage of chytridiomycosis. “Figuring out the basic biology of Bd will hopefully give insight into disease mitigation in the future,” Prostak says.

With four tiny legs and an extraordinarily long body, a fossil of the snake-like lizard Tetrapodophis amplectus has created controversy. Credit: Julius Csotonyi More than 120 million years ago in what is now modern Brazil, an ancient waterway was filled with all manner of strange creatures. These included dinosaurs, pterosaurs, sharks, bony fishes, a dizzying array of insects, strange plants and an oddly long and small lizard: Tetrapodophis amplectus. In 2015, the journal Science published a paper claiming that this elongate lizard was a snake with four legs. The discovery of such a specimen could tell us a great deal about the pattern and process of snake evolution — if it was indeed a snake. Lizard, not snake Extraordinary claims attract extraordinary attention, and this means such claims require reanalysis — and possibly refutation or corroboration. In scientific research, the data must fit the hypothesis, and if it does not, then the hypothesis is rejected. In late 2015, two members of our research team traveled to Solnhofen, Germany, to study the specimen and conduct firsthand observation of the anatomy of the fossil. After all, the preserved anatomy is the data upon which all subsequent hypotheses are based. The results of our team’s detailed anatomical restudy of Tetrapodophis refute the hypothesis that it is a snake. We also challenged the claims in the original article that it possessed both a wide gape for eating large prey and the ability to coil its body and constrict its prey. Using these corrected data, our analyses of evolutionary relationships found Tetrapodophis to be a dolichosaur, not a snake. Dolichosaurs are an extinct group of elongated, limb-reduced lizards related to mosasaurs. Both are thought to be close relatives of snakes. It is therefore not surprising that there are some anatomical similarities between Tetrapodophis and snakes. It’s all in the bones Many fossils are found by splitting open a slab of rock using a hammer and chisel. The fossil of Tetrapodophis was found this way and is now on two slabs of rock. The skull slab includes impressions of the skeleton, while the second slab preserves the natural mold of the skull and most of the remaining skeleton. The preserved skull bones are shattered into tiny bits and the ones that remain intact are from the left side of the skull. Only the front part of the left lower jaw is relatively well-preserved and it is similar to that of a dolichosaur, not a snake. The fossil’s skull provided the most revealing clues about the creature’s identity. Credit: Michael Caldwell The bones of the right side of the skull are gone, but their impressions are preserved on the other slab and were not described in the first article detailing the find. The bones behind the eye that form a barrier for the jaw closing muscles are complete in Tetrapodophis. But they are absent in all fossil and living snakes. The quadrate bone, which suspends the lower jaw from the skull in lizards, is also preserved. In Tetrapodophis it is identical to that of a dolichosaur and other mosasaurians, not as in snakes. Limb reduction and loss are not unique to snakes. Numerous living lizards — for example, skinks, anguids and pygopodid geckos — are legless or limb-reduced. They all evolved leglessness independent of each other — known as convergent evolution — but retained the skull features of their respective lizard kind. The same is true for snakes. A bizarre little lizard Tetrapodophis is an amazing and bizarre little lizard even without being interpreted as a four-legged snake. It is very small, yet the body skeleton, from the back of the skull to the tip of the tail, is exceptionally elongated. Unlike any other lizard with limbs, Tetrapodophis has about 148 vertebrae between the front legs and the hips. Also, its tail is very long and has an additional 112 vertebrae. Part and Counterpart of Tetrapodophis. Credit: Michael Caldwell No other lizard with four legs shows this anatomy, and it is not seen or predicted in snakes either. The body is flattened from side to side, which would have helped it swim in the water. The limbs are tiny, with the front legs being almost vestigial, and most of the wrist and ankle elements are not ossified. Clearly, it could not walk on land using its limbs. Nor could it dig or grasp any prey as originally argued. Fossils and belonging Scientific research is not independent from social, political, and economic contexts. Scientific specimens — in paleontology, genetics, archeology or any other field — have a provenance and are intimately linked to people, culture, countries and laws. Scientific specimens are governed by legislation that outlines how they can be collected and used. This includes countries that in the past suffered from “parachute science” where specimens were removed, legally or illegally, and local scientists were excluded from participating in the research. This practice is now widely condemned as scientists collectively work to decolonize science. Unfortunately, Tetrapodophis is embroiled in such legal and ethical issues. Since 1942, the law in Brazil has been clear: no fossils can be privately owned. And since 1990, international researchers may only collect in Brazil in partnership with local institutions. The type specimen — the specimen used as a reference point — of any new species must also remain in Brazil. These legal requirements have been ignored and publicly mocked by one of the authors of the 2015 study. As of November 2021, the specimen of Tetrapodophis remains in Germany in a private collection, on loan to a private museum: the Bürgermeister-Müller Museum Solnhofen. Its passage from Brazil to that private German collection is unknown. Ethical matters The scientific study of privately owned fossil specimens also runs afoul of ethics policies, such those of the Society of Vertebrate Paleontology. If science is based on the ability to test and retest ideas by re-examining data, then the specimens must always be openly available for study. The concern in paleontology is that private owners of specimens can block that freedom of access and thus unethically limit the science. Tetrapodophis is proof of this problem. Because of damage to the specimen in 2016 by another research team, and contrary to claims that the specimen would be publicly accessible, the owner blocked access to the specimen. Some scientists have pronounced that this means Tetrapodophis is dead to science. We disagree with this conclusion. Despite the controversies, the original paper has not been retracted by Science, and there are also thousands of published references to “Tetrapodophis the four-legged snake.” We completed our re-examination of the specimen in an effort to correct the record and describe this bizarre fossil lizard for what it is. We also hope that by doing so, we will have reignited the discussion around the specimen with the goal of repatriating it to Brazil.

Credit: Farzaneh Aboualizadeh SATiN Enables Fast, Accurate, and Low-Cost COVID-19 Antibody Testing Igor Stagljar made his career building molecular tools to combat cancer. But when the pandemic hit last March, he aimed his expertise at a new adversary, SARS-CoV-2. Stagljar is a professor of biochemistry and molecular genetics in the Donnelly Centre for Cellular and Biomolecular Research at U of T’s Temerty Faculty of Medicine. Last spring, with support from U of T’s Toronto COVID-19 Action Fund, his team began developing a new method for measuring immunity to coronavirus in those who recovered from COVID-19. They are now ready to reveal their creation — a pinprick test that accurately measures in under one hour concentration of coronavirus antibodies in the blood. And it’s cheap, costing a toonie (CAD $2, US $1.59) or about a tenth of the cost of the market gold standard. Their method has been published in a study in the journal Nature Communications. High Accuracy at a Low Cost “Our assay is as sensitive, if not better than any other currently available assay in detecting low levels of IgG antibodies, and its specificity, also known as false-positive rate, is as good as the best antibody test on the market,” said Stagljar who collaborated with public health agencies and blood banks from across Canada to have the test validated on blood samples taken from former COVID-19 patients. Serological tests detect antibodies, protein molecules in blood that recognize and neutralize Sars-CoV-2 to prevent infection. Such tests are seen as a key tool for public health experts wanting to measure population immunity to be better able to manage the ongoing pandemic. According to a January report by the National COVID Immunity Task Force, the majority of Canadians remain vulnerable to coronavirus infection with less than two percent testing positive for antibodies. Population-level studies can also help reveal the duration of coronavirus immunity across patients who had different experiences of disease, from asymptomatic to severe. They also have the potential to reveal the threshold antibody level required for protection after natural infection and vaccination. “That level is still to be determined, but we do know that people who have been infected with SARS-CoV-2 have very diverse levels of antibodies, and it would not be surprising to find that below some baseline level they might not be protective,” said Zhong Yao, senior research associate in Stagljar’s lab and coinventor of the testing method. Several serological tests have received regulatory approval with ELISA-based methods as the gold standard when it comes to measuring antibody concentration as a strength of individual immune response. But it comprises several laboratory steps that take six hours to complete, making it unsuitable for rapid diagnostics. Simpler methods using test strips, similar to pregnancy tests, provide fast results but are not quantitative and are less reliable. SATiN: A Game-Changing Serology Tool The new method is called SATiN, for Serological Assay based on split Tripart Nanoluciferase. It is the first COVID-19 serology test that uses highly sensitive protein complementation chemistry in which a light-emitting luciferase protein is reconstituted from separate fragments as test readout. Luciferase is initially supplied in fragments that cannot glow on their own. One piece is attached on the viral spike protein, which antibodies bind to neutralize the virus, while another is hooked to a bacterial protein that antibodies also interact with. By binding simultaneously to the coronavirus spike protein and the bacterial protein, the antibody helps lock luciferase pieces together into a whole molecule. A flash of light ensues whose intensity is detected and converted into antibody concentration by a plate reader instrument. All reagents can be prepared from scratch and in bulk and this keeps the cost down. Stagljar is now working with U of T’s intellectual property office and Toronto Innovation Acceleration Partners to find industry partners that would help make the method widely available. He is also collaborating with Dr. Prabhat Jha, Director of the Centre for Global Health Research at St. Michael’s Hospital and a professor at U of T’s Dalla Lana School of Public Health, who is leading a long-term study to establish the duration of immunity across 10,000 Canadians. In another project, Stagljar is working with Dr. Allison McGeer, Senior Clinician Scientist at Sinai Health System and also a professor at Dalla Lana, to assess antibody levels in people after vaccination. “It’s really useful to have that quantitative ability to know what someone’s antibody status is, whether it’s from a past infection or a vaccination. This will be of crucial importance for the next stage of the pandemic, especially now when governments of all countries started with mass vaccinations with recently approved anti-COVID-19 vaccines,” Stagljar said.
