New research reveals a hybrid cell type in the human brain that exhibits both neuronal and glial properties, capable of generating electrical signals. This finding, important for glioma and normal brain function, suggests potential prognostic value in cancer treatment. Credit: SciTechDaily.com Scientists from Baylor College have identified a new cell type in the human brain that shares properties of neurons and glia. These cells, also found in glioma tumors, are capable of firing electrical impulses, challenging the conventional belief that only neurons can do so. Discovery of New Cell Type in Human Brain Researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital have uncovered a new cell type in the human brain. The study published today (September 5) in the journal Cancer Cell reveals that a third of the cells in glioma, a type of brain tumor, fire electrical impulses. Interestingly, the impulses, also called action potentials, originate from tumor cells that are part neuron and part glia, supporting the groundbreaking idea that neurons are not the only cells that can generate electric signals in the brain. The scientists also discovered that cells with hybrid neuron-glia characteristics are present in the non-tumor human brain. The findings highlight the importance of further studying the role of these newly identified cells in both glioma and normal brain function. Impact on Glioma Research and Patient Survival “Gliomas are the most common tumors of the central nervous system with an estimated 12,000 cases diagnosed each year. These tumors are universally lethal and have devastating effects on neurological and cognitive functions. Previous studies have shown that patient survival outcomes are associated with tumor proliferation and invasiveness, which are influenced by tumor intrinsic and extrinsic factors, including communication between tumor cells and neurons that reside in the brain,” said Dr. Benjamin Deneen professor and Dr. Russell J. and Marian K. Blattner Chair in the Department of Neurosurgery, director of the Center for Cancer Neuroscience, a member of the Dan L Duncan Comprehensive Cancer Center at Baylor and a principal investigator at the Jan and Dan Duncan Neurological Research Institute. Researchers have previously described that glioma and surrounding healthy neurons connect with each other and that neurons communicate with tumors in ways that drive tumor growth and invasiveness. Unveiling Electrical Activity in Cancer Cells “We have known for some time now that tumor cells and neurons interact directly,” said first author Dr. Rachel N. Curry, postdoctoral fellow in pediatrics – neuro oncology at Baylor, who was responsible for conceptualizing the project. “But one question that always lingered in my mind was, ‘Are cancer cells electrically active?’ To answer this question correctly, we required human samples directly from the operating room. This ensured the biology of the cells as they would exist in the brain was preserved as much as possible.” To study the ability of glioma cells to spike electrical signals and identify the cells that produce the signals, the team used Patch-sequencing, a combination of techniques that integrates whole-cell electrophysiological recordings to measure spiking signals with single-cell RNA-sequencing and analysis of the cellular structure to identify the type of cells. Innovative Methods and Unexpected Findings The electrophysiology experiments were conducted by research associate and co-first author Dr. Qianqian Ma in the lab of co-corresponding author associate professor of neuroscience Dr. Xiaolong Jiang. This innovative approach has not been used before to study human brain tumor cells. “We were truly surprised to find these tumor cells had a unique combination of morphological and electrophysiological properties,” Ma said. “We had never seen anything like this in the mammalian brain before.” “We conducted all these analyses on single cells. We analyzed their individual electrophysiological activity. We extracted each cell’s content and sequenced the RNA to identify the genes that were active in the cell, which tells us what type of cell it is,” Deneen said. “We also stained each cell with dyes that would visualize its structural features.” Analysis and Computational Advances in Neuroscience Integrating this vast amount of individual data required the researchers to develop a novel way to analyze it. “To define the spiking cells and determine their identity, we developed a computational tool – Single Cell Rule Association Mining (SCRAM) – to annotate each cell individually,” said co-corresponding author, Dr. Akdes Serin Harmanci, assistant professor of neurosurgery at Baylor. Broader Implications for Neuroscience and Clinical Practice “Finding that so many glioma cells are electrically active was a surprise because it goes against a strongly held concept in neuroscience that states that, of all the different types of cells in the brain, neurons are the only ones that fire electric impulses,” Curry said. “Others have proposed that some glia cells known as oligodendrocyte precursor cells (OPCs) may fire electrical impulses in the rodent brain, but confirming this in humans had proven a difficult task. Our findings show that human cells other than neurons can fire electrical impulses. Since there is an estimated 100 million of these OPCs in the adult brain, the electrical contributions of these cells should be further studied.” “Moreover, the comprehensive data analyses revealed that the spiking hybrid cells in glioma tumors had properties of both neurons and OPC cells,” Harmanci said. “Interestingly, we found non-tumor cells that are neuron-glia hybrids, suggesting that this hybrid population not only plays a role in glioma growth but also contributes to healthy brain function.” “The findings also suggest that the proportion of spiking hybrid cells in glioma may have a prognostic value,” said co-corresponding author Dr. Ganesh Rao, Marc J. Shapiro Professor and chair of neurosurgery at Baylor. “The data shows that the more of these spiking hybrid glioma cells a patient has, the better the survival outcome. This information is of great value to patients and their doctors.” Collaboration and Conclusions in Cancer and Brain Research “This work is the result of extensive equal collaboration across multiple disciplines – neurosurgery, bioinformatics, neuroscience, and cancer modeling – disciplines strongly supported by state-of-the-art groups at Baylor,” Deneen said. “The results offer an enhanced understanding of glioma tumors and normal brain function, a sophisticated bioinformatics pipeline to analyze complex cellular populations and potential prognostic implications for patients with this devastating disease.” Reference: “Integrated electrophysiological and genomic profiles of single cells reveal spiking tumor cells in human glioma” by Rachel N.

Scientists investigate the evolution of Mimivirus, one of the world’s largest viruses, through how they replicate DNA. Credit: Indian Institute of Technology Bombay Researchers from the Indian Institute of Technology Bombay shed light on the origins of Mimivirus and other giant viruses, helping us better understand a group of unique biological forms that shaped life on Earth. In their latest study published in Molecular Biology and Evolution, the researchers show that giant viruses may have come from a complex single-cell ancestor, keeping DNA replication machinery but shedding genes that code for other vital processes like metabolism. 2003 was a big year for virologists. The first giant virus was discovered this year, which shook the virology scene, revising what was thought to be an established understanding of this elusive group and expanding the virus world from simple, small agents to forms that are as complex as some bacteria. Because of their link to disease and the difficulties in defining them—they are biological entities but do not fit comfortably in the existing tree of life— viruses incite the curiosity of many people. Scientists have long been interested in how viruses evolved, especially when it comes to giant viruses that can produce new viruses with very little help from the host—in contrast to most small viruses, which utilize the host’s machinery to replicate. Even though giant viruses are not what most people would think of when it comes to viruses, they are actually very common in oceans and other water bodies. They infect single-celled aquatic organisms and have major effects on the latter’s population. In fact, Dr. Kiran Kondabagil, molecular virologist at the Indian Institute of Technology (IIT) Bombay, suggests, “Because these single-celled organisms greatly influence the carbon turnover in the ocean, the viruses have an important role in our world’s ecology. So, it is just as important to study them and their evolution, as it is to study the disease-causing viruses.” Scientists investigate the evolution of Mimivirus, one of the world’s largest viruses, through how they replicate DNA. Researchers from the Indian Institute of Technology Bombay shed light on the origins of Mimivirus and other giant viruses, helping us better understand a group of unique biological forms that shaped life on Earth. Credit: Indian Institute of Technology Bombay In a recent study, the findings of which have been published in Molecular Biology and Evolution, Dr. Kondabagil and co-researcher Dr. Supriya Patil performed a series of analyses on major genes and proteins involved in the DNA replication machinery of Mimivirus, the first group of giant viruses to be identified. They aimed to determine which of two major suggestions regarding Mimivirus evolution—the reduction and the virus-first hypotheses— were more supported by their results. The reduction hypothesis suggests that the giant viruses emerged from unicellular organisms and shed genes over time; the virus-first hypothesis suggests that they were around before single-celled organisms and gained genes, instead. Dr. Kondabagil and Dr. Patil created phylogenetic trees with replication proteins and found that those from Mimivirus were more closely related to eukaryotes than to bacteria or small viruses. Additionally, they used a technique called multidimensional scaling to determine how similar the Mimiviral proteins are. A greater similarity would indicate that the proteins coevolved, which means that they are linked together in a larger protein complex with coordinated function. And indeed, their findings showed greater similarity. Finally, the researchers showed that genes related to DNA replication are similar to and fall under purifying selection, which is natural selection that removes harmful gene variants, constraining the genes and preventing their sequences from varying. Such a phenomenon typically occurs when the genes are involved in essential functions (like DNA replication) in an organism. Taken together, these results imply that Mimiviral DNA replication machinery is ancient and evolved over a long period of time. This narrows us down to the reduction hypothesis, which suggests that the DNA replication machinery already existed in a unicellular ancestor, and the giant viruses were formed after getting rid of other structures in the ancestor, leaving only replication-related parts of the genome. “Our findings are very exciting because they inform how life on Earth has evolved,” Dr. Kondabagil says. “Because these giant viruses probably predate the diversification of the unicellular ancestor into bacteria, archaea, and eukaryotes, they should have had a major influence on the subsequent evolutionary trajectory of eukaryotes, which are their hosts.” In terms of applications beyond this contribution to basic scientific knowledge, Dr. Kondabagil feels that their work could lay the groundwork for translational research into technology like genetic engineering and nanotechnology. He says, “An increased understanding of the mechanisms by which viruses copy themselves and self-assemble means we could potentially modify these viruses to replicate genes we want or create nanobots based on how the viruses function. The possibilities are far-reaching!” Reference: “Coevolutionary and Phylogenetic Analysis of Mimiviral Replication Machinery Suggest the Cellular Origin of Mimiviruses” by Supriya Patil and Kiran Kondabagil, 11 February 2021, Molecular Biology and Evolution.

Odontoblasts containing the ion channel TRPC5 (green) tightly pack the area between the pulp and the dentin in a mouse’s molar. The cells’ long-haired extensions fill the thin canals in dentin that extend towards the enamel. Credit: L. Bernal et al./Science Advances 2021 Researchers have identified TRPC5, a protein in tooth cells, as the sensor behind cold sensitivity in decayed teeth. Blocking this protein, as clove oil does, may offer new ways to treat tooth pain. For people with tooth decay, drinking a cold beverage can be agony. “It’s a unique kind of pain,” says David Clapham, vice president and chief scientific officer of the Howard Hughes Medical Institute (HHMI). “It’s just excruciating.” Now, he and an international team of scientists have figured out how teeth sense the cold and pinpointed the molecular and cellular players involved. In both mice and humans, tooth cells called odontoblasts contain cold-sensitive proteins that detect temperature drops, the team reports March 26, 2021, in the journal Science Advances. Signals from these cells can ultimately trigger a jolt of pain to the brain. The work offers an explanation for how one age-old home remedy eases toothaches. The main ingredient in clove oil, which has been used for centuries in dentistry, contains a chemical that blocks the “cold sensor” protein, says electrophysiologist Katharina Zimmermann, who led the work at Friedrich-Alexander University Erlangen-Nürnberg in Germany. Developing drugs that target this sensor even more specifically could potentially eliminate tooth sensitivity to cold, Zimmermann says. “Once you have a molecule to target, there is a possibility of treatment.” Mystery Channel Teeth decay when films of bacteria and acid eat away at the enamel, the hard, whitish covering of teeth. As enamel erodes, pits called cavities form. Roughly 2.4 billion people — about a third of the world’s population — have untreated cavities in permanent teeth, which can cause intense pain, including extreme cold sensitivity. No one really knew how teeth sensed the cold, though scientists had proposed one main theory. Tiny canals inside the teeth contain fluid that moves when the temperature changes. Somehow, nerves can sense the direction of this movement, which signals whether a tooth is hot or cold, some researchers have suggested. “We can’t rule this theory out,” but there wasn’t any direct evidence for it, says Clapham a neurobiologist at HHMI’s Janelia Research Campus. Fluid movement in teeth — and tooth biology in general — is difficult to study. Scientists have to cut through the enamel — the hardest substance in the human body — and another tough layer called dentin, all without pulverizing the tooth’s soft pulp and the blood vessels and nerves within it. Sometimes, the whole tooth “will just fall to pieces,” Zimmermann says. Zimmerman, Clapham, and their colleagues didn’t set out to study teeth. Their work focused primarily on ion channels, pores in cells’ membranes that act like molecular gates. After detecting a signal — a chemical message or temperature change, for example — the channels either clamp shut or open wide and let ions flood into the cell. This creates an electrical pulse that zips from cell to cell. It’s a rapid way to send information, and crucial in the brain, heart, and other tissues. About fifteen years ago, when Zimmermann was a postdoc in Clapham’s lab, the team discovered that an ion channel called TRPC5 was highly sensitive to the cold. But the team didn’t know where in the body TRPC5’s cold-sensing ability came into play. It wasn’t the skin, they found. Mice that lacked the ion channel could still sense the cold, the team reported in 2011 in the journal Proceedings of the National Academy of Sciences. After that, “we hit a dead end,” Zimmermann says. The team was sitting at lunch one day discussing the problem when the idea finally hit. “David said, ‘Well, what other tissues in the body sense the cold?’ Zimmermann recalls. The answer was teeth. The Whole Tooth TRPC5 does reside in teeth — and more so in teeth with cavities, study coauthor Jochen Lennerz, a pathologist from Massachusetts General Hospital, discovered after examining specimens from human adults. A novel experimental set up in mice convinced the researchers that TRPC5 indeed functions as a cold sensor. Instead of cracking a tooth open and solely examining its cells in a dish, Zimmermann’s team looked at the whole system: jawbone, teeth, and tooth nerves. The team recorded neural activity as an ice-cold solution touched the tooth. In normal mice, this frigid dip sparked nerve activity, indicating the tooth was sensing the cold. Not so in mice lacking TRPC5 or in teeth treated with a chemical that blocked the ion channel. That was a key clue that the ion channel could detect cold, Zimmermann says. One other ion channel the team studied, TRPA1, also seemed to play a role. The team traced TRPC5’s location to a specific cell type, the odontoblast, that resides between the pulp and the dentin. When someone with a dentin-exposed tooth bites down on a popsicle, for example, those TRPC5-packed cells pick up on the cold sensation and an “ow!” signal speeds to the brain. That sharp sensation hasn’t been as extensively studied as other areas of science, Clapham says. Tooth pain may not be considered a trendy subject, he says, “but it is important and it affects a lot of people.” Zimmermann points out that the team’s journey towards this discovery spanned more than a decade. Figuring out the function of particular molecules and cells is difficult, she says. “And good research can take a long time.” Reference: “Odontoblast TRPC5 channels signal cold pain in teeth” by Laura Bernal, Pamela Sotelo-Hitschfeld, Christine König, Viktor Sinica, Amanda Wyatt, Zoltan Winter, Alexander Hein, Filip Touska, Susanne Reinhardt, Aaron Tragl, Ricardo Kusuda, Philipp Wartenberg, Allen Sclaroff, John D.
