A pseudo color scale shows differences in packing density of lipids on NK cell membrane, with warmer colors indicating higher density. Credit: Orange lab, CUIMC A newly discovered fat ‘shield’ that prevents natural killer cells from being destroyed by their own deadly biological weapons also allows some cancer cells to evade an immune system attack, a study at Columbia University has found. The findings, which may lead to new treatments for aggressive cancers, were reported on August 3, 2021, in the journal PLoS Biology by scientists in the Department of Pediatrics at Columbia University Vagelos College of Physicians and Surgeons. Natural killer cells are prolific assassins Natural killer cells are our body’s first line of defense against pathogens and cancer cells, always present and ready to strike at a moment’s notice.  Natural killer cells are efficient assassins that can eliminate up to six infected or cancer cells each day. The deadly immune cells grab onto their target and blast it with toxic substances—proteins and enzymes—that punch holes in the cell’s membrane. These substances are not especially selective and could easily destroy the natural killer cell’s membrane during the attack. But if these substances are so deadly, how do natural killer cells survive the blast? “I’ve been working on natural killer cells since the early 1990s, and every time I gave a talk about these cells, someone always asked that question,” says study leader and immunology expert Jordan Orange, MD, PhD, the Reuben S. Carpentier Professor of Pediatrics and chair of the Department of Pediatrics at Columbia University Vagelos College of Physicians and Surgeons. “And nobody really knew until now.” Shielded by fat Yu Li, a graduate student working with Orange to understand how natural killer cells work and co-author of the study, thought the answer might lay in the double layer of lipids—a type of fat—that makes up the outer membranes of all cells. Compared with other cells, Li noticed, the membranes of natural killer cells looked more orderly and more densely packed with lipids when viewed under a microscope. “There were a lot of hypotheses about why natural killer cells don’t kill themselves during their attack on other cells, but they all proposed there might be a magic, unknown protein protecting these cells,” Li says. But Li had doubts. “Based on biophysical considerations, I didn’t think a protein would be strong enough to protect the cells. When I looked at the cells, I thought of lipids.” Li put his theory to the test: he exposed the membranes to a compound that weakens the structure of the lipid layer. With less dense and less orderly membranes, the natural killer cells were unprotected from their own toxic blast—and perished along with their targets. Reinforcement arrives before natural killer cells attack To ensure their ability to survive, natural killer cells reinforce their membranes immediately before they launch an attack, Li found. Small granules that contain the deadly substances move to the outer edge of the natural killer cell. As the granule releases its cargo into the space between the killer and target cells, its own unusually dense lipid membrane merges with and reinforces the natural killer cell membrane. “In essence, Li found that the membrane turns into a blast shield,” Orange says. “And the protection comes from the way the membrane’s lipids are arranged. When the lipids are arranged in a more orderly fashion, more lipids can be packed into the membrane. The toxic substances simply can’t find a way into the membrane,” Orange says. Lipid blast shield also protects some cancer cells Natural killer cells are not the only ones to adopt lipid blast shields, Li and Orange also found.  At least some cancer cells have adopted the defense to protect themselves during attacks by natural killer cells (and possibly from cytotoxic T cells, another immune cell that uses lipids for protection). Li found that cells from an aggressive breast cancer known to be impervious to natural killer cells fortify their membranes during the attack. The fortification is essential in protecting the cancer cells, Li discovered, because when he added a membrane compound that disrupts lipid packing, the cancer cells were made vulnerable. “We don’t know yet if this is a general mechanism by which cancer cells resist natural killer cells,” Li says. “If it is generalizable, we can start to think of therapies that disrupt the tumor cell membrane and make it more susceptible to attack by the immune system.” Reference: “Degranulation enhances presynaptic membrane packing, which protects NK cells from perforin-mediated autolysis” by Yu Li and Jordan S.

Erratus Sperare — the new missing link fossil. Credit: The University of Manchester A newly discovered fossil, Erratus sperare, provides crucial evidence for the evolution of gills in arthropods, linking ancient specialized flaps to the biramous limbs of modern species. This discovery also suggests these gills evolved into wings and lungs. University of Manchester research fellow David Legg, in collaboration with a team of international scientists from China, Switzerland, and Sweden, has today announced a new fossil that reveals the origin of gills in arthropods. Arthropods, the group of animals that includes creepy crawlies like spiders and woodlice, are the largest phylum in the animal kingdom and are found everywhere from the deepest ocean trench to the top of Mount Everest. Research published on February 7, 2022, shows the newest addition to the group is a 520-million-year-old (about 10 times as old as the dinosaurs) organism called Erratus sperare. Erratus sperare was discovered in the Chengjiang Fossil Site, a UNESCO World Heritage Site located in Yunnan, China. The Chengjiang Fossil Site preserves an ancient underwater ecosystem which included the relatives of some well-known arthropod fossils like trilobites and anomalocarids. “Thanks to this new fossil, Erratus sperare, we now have a much clearer idea. These gills also probably went on to evolve into the wings of insects and the lungs of terrestrial arthropods like spiders so were a very important innovation.” Dr. David Legg Evolution of Biramous Limbs Modern water-dwelling arthropods have biramous limbs, legs that have two parts – one for breathing and one for walking – but how such specialized limbs evolved was a mystery. Some of the earliest fossil arthropods, like Anomalocaris, had swimming flaps that may have doubled as gills, but until now researchers didn’t know how arthropods made the jump from these specialized flaps to the biramous limbs of modern arthropods. Erratus sperare provides the missing link between arthropods that used such specialized flaps and arthropods with biramous limbs. It has both legs and flaps. Dr. David Legg, one of the authors of this study, said: “Fish aren’t the only organisms that have gills! Arthropods have gills too… they just have them on their legs. When it came to arthropods, however, we just weren’t sure where these gills came from. “Thanks to this new fossil, Erratus sperare, we now have a much clearer idea. These gills also probably went on to evolve into the wings of insects and the lungs of terrestrial arthropods like spiders so were a very important innovation.” Reference: “The evolution of biramous appendages revealed by a carapace-bearing Cambrian arthropod” by Dongjing Fu, David A.

In the U.S., bumble bees are typically seen as yellow and black, while in other regions, they display a range of colors. Researchers are exploring how evolutionary genetics shapes these regional variations in bee coloration. Utilizing the computational capabilities of the Roar supercomputer, a new study details how a Hox gene and its gene targets craft the unique color patterns of bumble bees, enhancing our understanding of genetic contributions to their mimicry and defensive signaling. While most people in the U.S. may think of bumble bees as the standard yellow and black variety, there are an estimated 260 bee species that sport about 400 different color patterns. One reason many people associate bumble bees with distinct colors is because evolution can influence multiple bee species to share similar color patterns in specific geographic regions, which scientists call mimicry. When multiple species mimic each other’s patterns they alert would-be predators in a certain area that when they see these colors, a painful sting may follow. In other places of the world, bees use a palette of blacks, oranges, reds, yellows, and whites to create that shared warning signal. Genetic Drivers of Bee Coloration Now, researchers are finding out more about the role that evolutionary genetics plays in shaping the distinctive color patterns that give different bee species their regional flare. In a study, the researchers report how a Hox gene, a major developmental gene that regulates the identity of structures on the segments of the bee, turns on a complex set of downstream genes that ultimately drive segmental changes in the bee’s pigmentation. “In a previous paper, what we couldn’t explain is how a change in the Hox gene called Abdominal-B leads to a change in the pigments that color these bees,” said Heather Hines, associate professor of biology and entomology. “In this particular paper, we were trying to fill in that gap and understand what genes are being targeted by this first gene, and what is the cascade of events that ultimately leads to these mimetic color differences.” Uncovering the Role of Pheomelanin in Insects The researchers, who report their findings in a recent issue of Genome Biology and Evolution, found that genomic targeting of a major developmental gene allows several melanin genes, rather than just one specific enzyme, to be altered to reinforce these color traits. They also said that the study adds to the knowledge about the genes involved in the production of a pigment called pheomelanin. The pigment was known to be involved in red coloration in vertebrates, but only recently was found to occur in insects. According to Hines, a lot of work remains on understanding the evolutionary genetics of these bees. “Understanding these genes, we now have the potential to look at so many different bee species and how they’ve diversified,” said Hines. “So, it’s not a case that once we are finished here that we’re done. Given the diversity in these bees, there’s just so much more that can be done with the discovery. This is just really the first step.” Researchers tend to use certain organisms — or model organisms — when they investigate evolutionary genetics because they are convenient and easy to study. This is one of the few studies that looked at coloration genes outside of these well-studied organisms, or non-models. Studying non-model systems allows researchers to understand the evolution of some of nature’s most exceptional diversifications of form, such as this color radiation. “This really adds to non-model, evolutionary genetic research, which is a growing field and the field is also expanding to be more comparative,” Hines said. “As we move forward, researchers will be looking at how genes and gene pathways have evolved across a broader diversity of species.” Computationally Expensive Research: ROAR to the Rescue “The use of high-performance computation power has made this type of research more manageable and reproducible,” said Sarthok Rahman, former doctoral student and ICDS student affiliate, Penn State and postdoctoral researcher in biological sciences, University of Alabama, and first author of the study. The researchers relied on the Institute for Computational and Data Sciences’ Roar supercomputer to provide that computational power for the gene expression studies on the bees. “We did the sequencing in the Genomics Core Facility, and then we mostly used the operational server for the differential gene expression analysis. Because it’s a non-model organism, we also have to use other genomic sources from Drosophila and mice, for example, to search the genes and assign the identity,” said Rahman. “These analyses can be pretty computationally expensive and would take a lot of time if it were done on an everyday laptop or desktop, which is why we used the ICDS supercomputing facility for this paper and the paper before it.” Reference: “Developmental Transcriptomics Reveals a Gene Network Driving Mimetic Color Variation in a Bumble Bee” by Sarthok Rasique Rahman, Tatiana Terranova, Li Tian and Heather M Hines, 21 April 2021, Genome Biology and Evolution.
