Biological condensates, membrane-less structures within cells, influence cellular electrochemistry and antibiotic resistance by altering electrical charge. A recent study reveals their far-reaching impact, suggesting they regulate important processes beyond their local environment. Researchers have found that a previously underestimated aspect of our cells has a significant impact by completing a gap in electrochemical processes. Historically, biological chemistry research has primarily concentrated on the most apparent components driving life’s processes. Proteins folding, genetic activity, and electrical signaling pathways have been the main areas of focus, as they offer the clearest targets for identifying abnormalities that cause disease. Recent research, however, has pointed to a different type of cellular structure that may play an equally important role. Called biological condensates, these structures exist because of differences in density, like oil droplets floating in water, and form compartments inside of cells without needing the physical boundary of a membrane. Previous studies have shown that these blobs can separate or trap together certain proteins and molecules, either hindering or promoting their activity. They have also revealed that these structures provide an alternative energy source that might power some aspects of biological chemistry. Beyond Local Impacts These results, however, have focused on impacts created in the immediate vicinity of the condensates themselves. Researchers had not yet identified ways in which they might affect biochemistry far from their physical structures. Now, in a new study published on September 10 in the journal Cell, researchers from Duke University and the Washington University in St. Louis have shown that the formation of biological condensates affects cellular activity far beyond their immediate vicinity. The results show that they may be a previously missing mechanism by which cells modulate their internal electrochemistry. And those internal controls, in turn, affect the cellular membrane, which allows these unassuming blobs to affect global traits and outcomes such as resistance to antibiotics. Biological condensates within cells – the yellow masses seen within these long cylinders – provide cells with a way to control their internal electrostatic biochemistry. Credit: Yifan Dai, Washington University of St. Louis “Our research shows that condensates influence cells well beyond direct physical contact, almost like they have a wireless connection to how cells interact with the environment,” said Lingchong You, the James L. Meriam Distinguished Professor of Biomedical Engineering at Duke. “Beyond demonstrating the electrical mechanisms behind this connection, we’ve proven that condensate formation can make cells more tolerant to certain types of antibiotics and more susceptible to others.” “This is likely just the tip of the iceberg,” added Ashutosh Chilkoti, the Alan L. Kaganov Distinguished Professor of Biomedical Engineering at Duke. “We expect that these electric potential effects express themselves in a wide variety of ways through cellular behaviors.” Electrostatic Mechanism of Condensates Condensates act sort of like a sponge, soaking up various proteins, enzymes, ions, and other biomolecules when they form, while excluding others. And if they trap enough ions in their compartment to become positively or negatively charged, that imbalance must be reflected in the cellular environment around them. This electrostatic activity provides a handle for the formation of biological condensates to affect the electrical potential of the cellular membrane and the electrochemical environment within the cell. And because these environmental factors are crucial to many biological processes, it provides a mechanism for these unassuming blobs to directly affect how cells interact with the world around them. Widespread Impact of Condensates “Even a tiny number of these condensates centrally distributed well away from the cell membrane can create a chain reaction that can change this global property,” explained Yifan Dai, an assistant professor of biomedical engineering and a member of the Center for Biomolecular Condensates at Washington University in St. Louis, who conducted the research as a postdoctoral researcher at Duke. “This paper shows there is no escape from these effects. As long as these tiny blobs form, many things are influenced, even gene regulation in a global scale. When I saw that, it was quite shocking to me.” To prove this point, the researchers worked to show that this phenomenon can affect how well bacteria survive interactions with certain antibiotics. The researchers caused colonies of E. coli bacteria to form internal condensates either by stressing them in just the right way or by manipulating the gene expression of the condensate-forming proteins. They then tested the resulting electrical charge in their cellular membranes and exposed them to antibiotics. The results showed that condensate formation caused some cellular membranes to become more negatively charged, which directly affected whether or not the cells reacted to the antibiotics, since they are also charged particles. But this is just the beginning of this line of research, the researchers say, as many biochemical processes depend on the electric potential held within the cellular membrane. “Our work uncovers a role of condensates in regulating global cellular physiology,” You said. “While we don’t yet have a concrete mechanistic understanding of how cells are deploying this activity to regulate their functionality, it’s a major discovery that it’s happening at all.” Reference: “Biomolecular condensates regulate cellular electrochemical equilibria” by Yifan Dai, Zhengqing Zhou, Wen Yu, Yuefeng Ma, Kyeri Kim, Nelson Rivera, Javid Mohammed, Erica Lantelme, Heileen Hsu-Kim, Ashutosh Chilkoti and Lingchong You, 10 September 2024, Cell.

Ceroptres promethea is one of the newly identified and named gall wasps. Credit: Penn State A team led by Penn State researchers identified 22 new species of gall wasps, naming them after famous thieves. This discovery opens new opportunities for future research on the biology and ecology of these understudied wasps. A Penn State College of Agricultural Sciences graduate student has led research that has resulted in the discovery and naming of 22 new species of gall wasps for the first time. The study, which includes the new names and descriptions of each species along with an identification guide, recently was published in the journal Zootaxa and nearly doubles the number of known species in this genus of wasps. The tiny wasps — which live in small structures called galls that they steal from other wasps — were named after famous thieves and tricksters in history, mythology, and pop culture, such as Catwoman and Han Solo. Creative Naming and Identification For example, they named one wasp after Prometheus, a titan in Greek mythology who stole fire from the gods and brought it to humanity. The researchers said they felt that the wasp’s fiery red coloring made it a natural fit for the name. The list of 22 names are: C. anansii, C. anzui, C. bruti, C. curupira, C. daleki, C. dandoi, C. demerzelae, C. iktomii, C. jabbai, C. jarethi, C. lokii, C. lupini, C. mallowi, C. promethei, C. sandiegoae, C. selinae, C. soloi, C. songae, C. swiperi, C. thrymi, C. tikoloshei, and C. zorroi. Louis Nastasi, doctoral student of entomology at Penn State and lead author on the paper, said now that the species have been properly identified, it opens the door for more research on the wasps, which are relatively understudied. “By naming these species, we give other researchers an anchor they can carry forward to other studies because now they can identify wasps that were previously unknown,” he said. “It provides a base and a tool kit for future work that could help us understand these species and their ecosystems more broadly.” The research stemmed from a separate study by another team — which also co-authored the current study — focused on the evolution of gall wasps. Despite having DNA data from multiple wasps, the researchers were unable to pinpoint which species they were actually dealing with. The team, which has had a long-standing collaboration with Nastasi, re-connected with him at the International Plant Gall Symposium, spurring a discussion about the mystery. “I ended up in conversation with Andrew Forbes, who’s the leader of the University of Iowa team, and he told me about the difficulties they were having,” Nastasi said. “And since my area of expertise is species identification, description and diagnosis of these tiny wasps, he asked if it would be possible for me to get involved and figure out what exactly is going on.” Upon receiving the wasp samples, Nastasi said he realized that the reason the other researchers were having a difficult time identifying them was because those particular species had never been officially discovered and named. To begin, Nastasi combined biological and molecular information on the species from the team’s previous study with his own morphological analysis, which looks at the anatomy and physical characteristics of the insects. Comprehensive Analysis and Species Naming Nastasi said it was essential to use each of these three types of data, as having just molecular data or just looking at the insects’ physical appearance would not be enough to properly separate one species from another. “We found that some of the insects thought to be one single species were actually two independent species, and that using only the molecular data did not sufficiently separate them into multiple species,” he said. “We had to combine that information with this new morphological analysis, and then by combining those types of data, it allowed us to get a clear vision of what each of these species are.” Once the wasps were properly categorized into species, Nastasi said it was time to assign them names. One wasp was named Ceroptres selinae — inspired by Selina Kyle, better known as Catwoman from DC Comics. Another was named Ceroptres bruti, after Marcus Junius Brutus — the Roman politician who infamously betrayed Julius Caesar. A third was named Ceroptres soloi — after Hans Solo, a smuggler and thief portrayed by Harrison Ford in the Star Wars movies. “We tried to get a little more personal than just matching a list of names to a list of species,” Nastasi said. “It’s definitely fun to hypothesize why a name is suited to a certain species. A lot of effort goes into identifying these species and there’s a lot of art in choosing a good species name, so it was exciting to exemplify that and really carefully select names for these new species.” The study is just the beginning of understanding this group of wasps, which is going to take a lot more research to unlock, Nastasi said. While many other unknown species of gall wasps have been collected, many are waiting in drawers in museums for someone to begin the identification process. Additionally, little is known about the biology of these wasps, he added, so future studies could focus on furthering knowledge about their life cycle, for example. “We know they live in these galls, we know which galls they live in, but there’s still so much we don’t know,” Nastasi said. “For instance, how do they actually use the contents of the gall to feed themselves? It’s going to be interesting to see how our new species inform both future species discovery studies and research on the wasps themselves.” Reference: “One must imagine Sisyphus happy: Integrative taxonomic characterization of 22 new Ceroptres species (Hymenoptera: Cynipidae: Ceroptresini)” by Louis F.

Rockefeller University researchers have developed TrackerSci, a groundbreaking method for tracking the development and aging of brain cells, which could revolutionize the understanding of neurological diseases and aging. This technique has uncovered shifts in cell production in aging brains and has broader applications for studying cell dynamics across various organs. TrackerSci is a new tool for tracking brain cell development and aging, offering fresh insights into cellular changes over a lifetime and potential applications in various organ studies. Hospital nurseries routinely place soft bands around the tiny wrists of newborns that hold important identifying information such as name, sex, mother, and birth date. Researchers at Rockefeller University are taking the same approach with newborn brain cells—but these neonates will keep their ID tags for life, so that scientists can track how they grow and mature, as a means for better understanding the brain’s aging process. Advancements in Cell Tracking As described in a new paper in the journal Cell, the new method developed by Rockefeller geneticist Junyue Cao and his colleagues is called TrackerSci (pronounced “sky”). This low-cost, high-throughput approach has already revealed that while newborn cells continue to be produced through life, the kinds of cells being produced greatly vary at different ages. This groundbreaking work, led by co-first authors Ziyu Lu and Melissa Zhang from Cao’s lab, promises to influence not only the study of the brain but also broader aspects of aging and disease across the human body. “The cell is the basic functional unit of our body, so changes to the cell essentially underlie virtually every disease and the aging process,” says Cao, head of the Laboratory of Single-Cell Genomics and Population Dynamics. “If we can systematically characterize the different cells and their dynamics using this novel technique, we may get a panoramic view of the mechanisms of many diseases and the enigma of aging.” Rare and Powerful New cells are continuously produced in the adult mammalian brain, a critical process associated with memory, learning, and stress. They develop from progenitor cells—descendants of adult stem cells that differentiate into specialized cell types. How this process unfolds, however, has been largely unknown, both because of technological limitations and cell rarity. Finding progenitor cells in the brain is a needle-in-haystack endeavor; in mammals, they account for a mere .5 percent of all brain cells. That number drops to .1 percent in later stages of life—a downward shift due to cellular instability, a core characteristic of disease and aging. Cao studies how tissues and organs maintain stable populations of cells—a hallmark of health—so he and his team wanted to investigate how different cellular populations develop, and whether these varied neuronal cells decline in the same way or forge different paths. Tracking their cellular lifespans from birth to maturity would reveal not just differences, but also when they appeared. His lab specializes in optimizing methods for single-cell sequencing, an increasingly popular approach to analysis that homes in on the genetic expression and molecular dynamics of individual cells. Cao’s group uses combinatorial indexing, a sophisticated yet cost-effective technique that allows for the simultaneous analysis of millions of cells. This method uniquely tags cellular molecules with distinct barcodes that correlate to each cell’s unique molecular assembly. With TrackerSci, Cao and his colleagues have fine-tuned this technique even further. This enhancement enables the meticulous labeling and tracking of the dynamics of rare progenitor cells in mammalian organs. “It’s like an ID card and GPS tracker combined,” Cao says. Aging Brain: Surprising Cellular Shifts For the current study, the researchers analyzed more than 10,000 newborn progenitor cells from across entire mouse brains spanning three ages (young, mature, and elderly) with a synthetic molecule known as 5-ethynyl-2-deoxyuridine (EdU). As these newborn cells differentiated, proliferated, and dispersed, EdU continued to label their DNA, functioning like a GPS tracker. This innovative technique allowed the researchers to analyze tens of thousands of gene expressions and the chromatin landscapes of these newborn cells as they grew into families of cell types with different molecular functions. “We were able to quantify cellular proliferation and differentiation rates of many cell types across the entire brain in a single experiment, which wasn’t possible using conventional approaches,” Cao says. “Those only capture static information—the current molecular state of a cell at a single moment. But TrackerSci captures dynamic information over time. It’s like other methods take snapshots, and we shoot a film.” Some clear—and surprising—characters emerged from these movies. Most strikingly, there were radical shifts in the type of cells generated, depending on the age of the mouse. For example, the number of progenitors that become neurons, the essential communicative cells of the brain, is higher in young brains. The same is the case for a range of glial cells, which create a stable environment for neurons by ensheathing them, providing nutrients, and defending against pathogens—all important for a young, still-developing organ. The opposite is true in the elderly brain. Progenitor cells rarely become either neurons or glial cells; in fact, virtually every type of brain cell plummets. Most lost are dentate gyrus neuroblasts, which are essential for creating neurons in the hippocampus, a region linked to memory and diseases like Alzheimer’s. In comparison to the adult brain, the number of these cells drops by 16-fold in the elderly brain. Instead, immune cells and microglia, a kind of macrophage, proliferate in the aging brain. But rather than protect the brain, they convert into an inflammatory cellular state specific to aging—and these cells are produced at a higher rate. In short, the aging brain creates more of the cells that create more problems for the aging brain. The Sci’s the Limit Cao says TrackerSci could be used to track the regenerative capacity of many organs. “We’re not a brain lab,” he notes. “We also tested the protocol for profiling progenitor cells in the lung, colon, pancreas, and many different organs.” Other organs have far higher proportions of progenitor cells than brains do; newborn progenitors account for more than 20 percent of the cells in the colon, for instance. A few years ago, Cao demonstrated the potential for analyzing cell population dynamics in human fetal development by creating a cellular atlas using a similar combinatorial indexing method. TrackerSci is one of several single-sequencing techniques to recently emerge from Cao’s lab. Another, called PerturbSci-Kinetics, developed by graduate student Zihan Xu, decodes the genome-wide regulatory network that underlies RNA temporal dynamics by coupling scalable single-cell genomics with high-throughput genetic perturbations, or manipulations that can influence gene function. The method was recently described in a paper in Nature Biotechnology.
