Researchers have developed a guide for detecting rare B cells, crucial in understanding food allergies and immune responses. Utilizing a technique involving antigen tetramers, this work facilitates the study of these cells’ diverse roles, from combating diseases to causing allergies. The research also extends to assessing vaccine efficacy, potentially aiding global scientific advancement. Credit: SciTechDaily.com Researchers have developed a guide for detecting rare B cells, crucial in understanding food allergies and immune responses. Scientists at McMaster University have created an instruction manual that will help scientists across the globe find hard-to-detect B cells. Led by PhD student Alyssa Phelps and Department of Medicine Assistant Professor Josh Koenig, researchers wanted to chart a path to finding these cells as part of their work in understanding food allergies. Their work will be published today (January 19) in the journal Nature Protocols. Understanding B Cells B cells are a type of immune cell that makes antibodies. These cells help fight conditions like cancer and infections but can also cause autoimmune diseases and allergies. “One of the big problems with trying to study these B cells, the ones that make these antibodies that have all kinds of different and very important functions, is that they’re really, really, rare. It’s hard to find them. And so, you have to have very good tools that will help you study these things,” Koenig says. To give an example of just how rare these cells can be, Koenig pointed to a peanut-specific B cell. It makes up less than 0.0001 percent of immune cells in human blood. Advanced Methodology The team adopted a method originally created by Justin Taylor, who now operates the Taylor Lab out of the University of Virginia. Taylor created a method using antigen tetramers to sensitively tag and enrich specific B cells so they can be detected. Tetramers are made up of four antigen molecules, which in this case, can be customized by scientists. The customization is vast and can cover everything from peanuts to COVID-19 specific B cells. “After using the technology for a few years in several of our studies and making multiple different allergen tetramers and antigen tetramers for other people, we decided to write up a protocol paper to help other people study these incredibly important B cells,” says Phelps. Broader Implications In addition to better understanding how allergies work in humans, tetramers can be used to study the efficacy of vaccines. This is something that was done by Koenig and his team in assisting McMaster researchers Matthew Miller, Brian Lichty, and Zhou Xing in determining whether their vaccine candidate activated protective COVID-specific B cells. “With these protocols now published, more researchers around the globe will be able to make these types of tools to help to push their science ahead,” Taylor says.

Recent research by Harvard’s Ortega-Hernández and Marc Mapalo has enhanced understanding of tardigrades by identifying a new species and providing evidence of their ancient origins and survival mechanisms through detailed amber fossil analysis. Harvard scientists have discovered a new tardigrade species in amber, offering insights into their evolutionary history and survival strategies. Tardigrades, also known as “water bears,” are eight-legged microscopic organisms known for their incredible resilience. These remarkable micro-animals can survive anything from deadly radiation to arctic temperatures to the vacuum of space. Although they can be found anywhere on Earth where there’s water, the evolutionary history of tardigrades remains relatively mysterious because of their sparse fossil record. A new study by Associate Professor Javier Ortega-Hernández and PhD candidate Marc Mapalo (both in the Department of Organismic and Evolutionary Biology at Harvard) has not only shed light on that history but also confirmed another entry in the fossil record, which now stands at a mere four specimens. Left: Amber with Beorn and Aerobius; Right: Artistic reconstruction of the two fossil specimens.

Using confocal laser microscopy, a method usually employed for studying cell biology, the researchers were able to examine the tiny structures of the fossil tardigrades in stunning detail. Ortega-Hernández and Mapalo’s study provides not only a definitive classification of B. leggi in the tardigrade family tree but also the identification of a new species of tardigrade.

The team named it Aerobius dactylus, from “aero” meaning relating to air—because the fossil appears to be floating on air in the amber—and “dactylo”, or finger, after its one long claw.

Credit: Marc Mapalo Advances in Tardigrade Research The impetus for applying this new technology to known fossils came when Mapalo, a self-described “paleo-tardigradologist,” came across the 2019 book, Water Bears: The Biology of Tardigrades. “In one of the chapters, they had a photo of the oldest fossil tardigrade that was visualized using both normal microscopy and confocal laser microscopy,” Mapalo said. “And that gave me the idea to use that with the fossil that I’m working with right now.” That fossil, encased in a piece of amber from the Dominican Republic, turned out to be a new species of tardigrade. Mapalo, along with Ortega-Hernández and researchers from the New Jersey Institute of Technology, published their findings in a 2021 paper in the Proceedings of the Royal Society B. Insights into Tardigrade Evolution Ortega-Hernández said that, in their latest study, both fossils serve as critical calibration points for what’s called molecular clock analysis, which helps scientists estimate the timing of key evolutionary events. For example, the latest findings suggest that modern tardigrades likely diverged during the Cambrian Period over 500 million years ago. The research also sheds light on the origin of cryptobiosis, the technical name for the remarkable ability of tardigrades to survive extreme conditions by entering a state of stasis. ”The study estimates that this survival mechanism likely evolved during the mid to late Paleozoic, which may have played a crucial role in helping tardigrades endure the end-Permian mass extinction, one of the most severe extinction events in Earth’s history,” Ortega-Hernández said. Impact on Paleontology Ortega-Hernández and Mapalo’s research represents a significant advancement in the field of paleontology because it offers new avenues for exploring the evolutionary history of one of the most resilient life forms on the planet. “Before I started my PhD, there were only three known fossil tardigrades, and now there’s four,” Mapalo said. “Most, if not all, of the fossil tardigrades were really discovered by chance. With the Dominican amber, researchers were looking for fossil ants, and they happened to see a fossil tardigrade there. “That’s why, whenever I have a chance, I always tell researchers who are working with amber fossils to check if maybe there’s another tardigrade in there, waiting to be found.” Reference: “Cretaceous amber inclusions illuminate the evolutionary origin of tardigrades” by Marc A.

University of Oregon researchers discovered a 480-million-year-old sex chromosome in the California two-spot octopus, making it one of the oldest known animal sex chromosomes. This finding confirms that cephalopods use chromosomes to determine sex. The chromosome was identified in female octopuses but not males, and further research found it in other cephalopods, suggesting an ancient and stable system. New research at the UO reveals that they have been using one that has existed for 480 million years. The octopus has just revealed another secret: what determines its sex. Researchers at the University of Oregon have identified a sex chromosome in the California two-spot octopus. This chromosome has likely existed for 480 million years, predating the evolutionary split between octopuses and nautiluses. That makes it one of the oldest known animal sex chromosomes. The discovery also provides evidence that octopuses and other cephalopods—a group of sea animals that includes squid and nautiluses—use chromosomes to determine their sex, solving a longstanding mystery among biologists. “Cephalopods are already such interesting creatures, and there are so many things we’re still learning about them, especially in neuroscience,” said Gabby Coffing, a doctoral student at the UO working in the lab of biologist Andrew Kern. “This is just showing one more interesting thing about them: They have really ancient sex chromosomes.” Coffing, Kern, and their team described the findings on February 3 in the journal Current Biology. How Animals Determine Sex In humans and most mammals, sex is determined largely by chromosomes. But “there’s a tremendous amount of diversity” in how animals determine their sex, Kern said. So scientists couldn’t assume the same was true for octopuses. In turtles, for instance, sex is determined by the temperature at which the eggs are incubated. Some fish have a gene that determines sex, but not a whole chromosome. Even in humans, the X/Y sex chromosome system isn’t as clear-cut as it might look on paper; gene mutations or inheriting extra sex chromosomes can lead to development that doesn’t neatly fit in a male/female binary. Plus, because cephalopods aren’t standard lab animals, like mice or fruit flies, they haven’t been subject to nearly as much genetic exploration. Scientists have sequenced the genomes of a handful of octopus species, but they can’t link genes to specific traits the way they can in mice or even humans. When UO researchers recently sequenced the DNA of a female California two-spot octopus, they found something unexpected: a chromosome with only half the amount of genetic material. It looked different from all the others, and it hadn’t been found in male octopuses whose DNA was previously sequenced. “This particular chromosome had half the amount of sequencing data, which indicated there was only one copy,” said Coffing. “Then as we explored that more, we reached the conclusion that we must have stumbled upon a sex chromosome.” Tracing the Chromosome’s Evolutionary History To confirm, the researchers sorted through other octopus genomic data previously collected by other researchers. Not all that data was clearly labeled as being from male or female octopuses. But they found another example of the half-sized chromosome in another species of octopus. They also found it in squid, which diverged evolutionarily from octopuses somewhere between 248 and 455 million years ago. And after more digging, they also found evidence for the chromosome in the nautilus, a mollusk that split apart from the octopus approximately 480 million years ago. The fact that these species share this unique chromosome suggests that it’s been around in some form for a very long time. “This indicates that their common ancestor had this similar sex determination system,” Coffing said. That’s somewhat unusual for sex chromosomes, Kern said. Because they directly impact reproductive capabilities, they’re subject to a lot of selective pressure and so tend to undergo rapid evolutionary change. But cephalopods seem to have found what works and have stuck with it. Other ancient sex chromosomes have been discovered in plant groups like mosses and liverworts, which were some of the first plants to evolve. And insect sex chromosomes might be 450 million years old, but they’ve also changed a lot over time. Kern and his colleagues initially thought octopuses might have a sex determination system similar to birds and butterflies, where males are ZZ and females are ZW. (Biologists have given sex determination systems where males have two copies of the same sex chromosome different letters, to avoid confusion with the XX/XY system where females have two copies of the same chromosome.) But the team hasn’t yet found a W chromosome in an octopus. Alternatively, octopuses could use a sex determination system that only involves the Z chromosome — males have a pair, and females just have one. That’s still to be determined, Coffing said. For now, the octopus keeps some of its secrets. Reference: “Cephalopod sex determination and its ancient evolutionary origin” by Gabrielle C. Coffing, Silas Tittes, Scott T. Small, Jeremea O.
