Credit: Nirosha Murugan, Levin lab, Tufts University and Wyss Institute at Harvard University Studies in brainless slime molds reveal that they use physical cues to decide where to grow. If you didn’t have a brain, could you still figure out where you were and navigate your surroundings? Thanks to new research on slime molds, the answer may be “yes.” Scientists from the Wyss Institute at Harvard University and the Allen Discovery Center at Tufts University have discovered that a brainless slime mold called Physarum polycephalum uses its body to sense mechanical cues in its surrounding environment, and performs computations similar to what we call “thinking” to decide in which direction to grow based on that information. Unlike previous studies with Physarum, these results were obtained without giving the organism any food or chemical signals to influence its behavior. The study was published today (July 15, 2021) in the journal Advanced Materials. “People are becoming more interested in Physarum because it doesn’t have a brain but it can still perform a lot of the behaviors that we associate with thinking, like solving mazes, learning new things, and predicting events,” said first author Nirosha Murugan, a former member of the Allen Discovery Center who is now an Assistant Professor at Algoma University in Ontario, Canada. “Figuring out how proto-intelligent life manages to do this type of computation gives us more insight into the underpinnings of animal cognition and behavior, including our own.” In this photo, a specimen of the slime mold Physarum polycephalum has chosen to grow toward the side of a petri dish with three glass discs rather than the side with one glass disc. Credit: Nirosha Murugan, Levin lab, Tufts University and Wyss Institute at Harvard University Slimy action at a distance Slime molds are amoeba-like organisms that can grow to be up to several feet long, and help break down decomposing matter in the environment like rotting logs, mulch, and dead leaves. A single Physarum creature consists of a membrane containing many cellular nuclei floating within a shared cytoplasm, creating a structure called a syncytium. Physarum moves by shuttling its watery cytoplasm back and forth throughout the entire length of its body in regular waves, a unique process known as shuttle streaming. “With most animals, we can’t see what’s changing inside the brain as the animal makes decisions. Physarum offers a really exciting scientific opportunity because we can observe its decisions about where to move in real-time by watching how its shuttle streaming behavior changes,” said Murugan. While previous studies have shown that Physarum moves in response to chemicals and light, Murugan and her team wanted to know if it could make decisions about where to move based on physical cues in its environment alone. This series of time-lapse photos shows a Physarum specimen growing in a generalized “buffering” pattern for ~13 hours, then extending a long growth toward the side of the dish with three discs. Credit: Nirosha Murugan, Levin lab, Tufts University and Wyss Institute at Harvard University The researchers placed Physarum specimens in the center of petri dishes coated with a semi-flexible agar gel and placed either one or three small glass discs next to each other atop the gel on opposite sides of each dish. They then allowed the organisms to grow freely in the dark over the course of 24 hours, and tracked their growth patterns. For the first 12 to 14 hours, the Physarum grew outwards evenly in all directions; after that, however, the specimens extended a long branch that grew directly over the surface of the gel toward the three-disc region 70% of the time. Remarkably, the Physarum chose to grow toward the greater mass without first physically exploring the area to confirm that it did indeed contain the larger object. How did it accomplish this exploration of its surroundings before physically going there? The scientists were determined to find out. It’s all relative The researchers experimented with several variables to see how they impacted Physarum’s growth decisions, and noticed something unusual: when they stacked the same three discs on top of each other, the organism seemed to lose its ability to distinguish between the three discs and the single disc. It grew toward both sides of the dish at roughly equal rates, despite the fact that the three stacked discs still had greater mass. Clearly, Physarum was using another factor beyond mass to decide where to grow. In this GIF, a specimen of the slime mold Physarum polycephalum has chosen to grow toward the side of a petri dish with three glass discs rather than the side with one glass disc. Credit: Nirosha Murugan, Levin lab, Tufts University and Wyss Institute at Harvard University To figure out the missing piece of the puzzle, the scientists used computer modeling to create a simulation of their experiment to explore how changing the mass of the discs would impact the amount of stress (force) and strain (deformation) applied to the semi-flexible gel and the attached growing Physarum. As they expected, larger masses increased the amount of strain, but the simulation revealed that the strain patterns the masses produced changed, depending on the arrangement of the discs. “Imagine that you are driving on the highway at night and looking for a town to stop at. You see two different arrangements of light on the horizon: a single bright point, and a cluster of less bright points. While the single point is brighter, the cluster of points lights up a wider area that is more likely to indicate a town, and so you head there,” said co-author Richard Novak, Ph.D., a Lead Staff Engineer at the Wyss Institute. “The patterns of light in this example are analogous to the patterns of mechanical strain produced by different arrangements of mass in our model. Our experiments confirmed that Physarum can physically sense them and make decisions based on patterns rather than simply on signal intensity.” The team’s research demonstrated that this brainless creature was not simply growing toward the heaviest thing it could sense — it was making a calculated decision about where to grow based on the relative patterns of strain it detected in its environment. But how was it detecting these strain patterns? The scientists suspected it had to do with Physarum’s ability to rhythmically contract and tug on its substrate, because the pulsing and sensing of the resultant changes in substrate deformation allows the organism to gain information about its surroundings. Other animals have special channel proteins in their cell membranes called TRP-like proteins that detect stretching, and co-author and Wyss Institute Founding Director Donald Ingber, M.D., Ph.D. had previously shown that one of these TRP proteins mediates mechanosensing in human cells. When the team created a potent TRP channel-blocking drug and applied it to Physarum, the organism lost its ability to distinguish between high and low masses, only selecting the high-mass region in 11% of the trials and selecting both high- and low-mass regions in 71% of trials. “Our discovery of this slime mold’s use of biomechanics to probe and react to its surrounding environment underscores how early this ability evolved in living organisms, and how closely related intelligence, behavior, and morphogenesis are. In this organism, which grows out to interact with the world, its shape change is its behavior. Other research has shown that similar strategies are used by cells in more complex animals, including neurons, stem cells, and cancer cells. This work in Physarum offers a new model in which to explore the ways in which evolution uses physics to implement primitive cognition that drives form and function,” said corresponding author Mike Levin, Ph.D., a Wyss Associate Faculty member who is also the Vannevar Bush Chair and serves and Director of the Allen Discovery Center at Tufts University. The research team is continuing its work on Physarum, including investigating at what point in time it makes the decision to switch its growth pattern from generalized sampling of its environment to directed growth toward a target. They are also exploring how other physical factors like acceleration and nutrient transport could affect the growth and behavior of Physarum. “This study confirms once again that mechanical forces play as important a role in the control of cell behavior and development as chemicals and genes, and the process of mechanosensation uncovered in this simple brainless organism is amazingly similar to what is seen in all species, including humans,” said Ingber. “Thus, a deeper understanding how organisms use biomechanical information to make decisions will help us to better understand our own bodies and brains, and perhaps even provide insight into new bioinspired forms of computation.” Ingber is also the Judah Folkman Professor of Vascular Biology at Harvard Medical School and Boston Children’s Hospital, and Professor of Bioengineering at the Harvard John A. Paulson School of Engineering and Applied Sciences. Reference: “Mechanosensation Mediates Long-Range Spatial Decision-Making in an Aneural Organism” by Nirosha J. Murugan, Daniel H. Kaltman, Paul H.

A mutation in the SARS-CoV-2 spike protein may be responsible for its increased ability to infect the brain, shedding light on COVID-19’s neurological impacts and potential treatment avenues. Credit: SciTechDaily.com Researchers have identified a key mutation in the spike protein of SARS-CoV-2 that increases its infectivity in the brain, potentially explaining the neurological symptoms of COVID-19 and the phenomena of “long COVID.” Still unknown what causes neurological complications of COVID-19 including ‘long COVID,’ ‘brain fog’ and loss of taste and smell Viruses with a deletion in the spike protein are better able to infect the brains of mice ‘These findings suggest there might be treatments that could work better to clear the virus from the brain’ ‘This could help us understand neurological symptoms of COVID-19’ Scientists have discovered a mutation in SARS-CoV-2, the virus that causes COVID-19, that plays a key role in its ability to infect the central nervous system. The findings may help scientists understand its neurological symptoms and the mystery of “long COVID,” and they could one day even lead to specific treatments to protect and clear the virus from the brain. The new collaborative study between scientists at Northwestern University and the University of Illinois-Chicago uncovered a series of mutations in the SARS-CoV-2 spike protein (the outer part of the virus that helps it penetrate cells) that enhanced the virus’ ability to infect the brains of mice. Implications for Brain Infection and Treatment “Looking at the genomes of viruses found in the brain compared to the lung, we found that viruses with a specific deletion in spike were much better at infecting the brains of these animals,” said co-corresponding author Judd Hultquist, assistant professor of medicine (infectious diseases) and microbiology-immunology at Northwestern University Feinberg School of Medicine. “This was completely unexpected, but very exciting.” The study will be published today (August 23) in the journal Nature Microbiology. Co-corresponding author Judd Hultquist in his lab at Northwestern University Feinberg School of Medicine. Credit: Northwestern University Changes in Spike Help the Virus Infect Different Cells in the Body In this study, researchers infected mice with SARS-CoV-2 and sequenced the genomes of viruses that replicated in the brain versus the lung. In the lung, the spike protein looked very similar to the virus used to infect the mice. In the brain, however, most viruses had a deletion or mutation in a critical region of spike that dictates how it enters a cell. When viruses with this deletion were used to directly infect the brains of mice, it was largely repaired when it traveled to the lungs. “In order for the virus to traffic from the lung to the brain, it required changes in the spike protein that are already known to dictate how the virus gets into different types of cells,” Hultquist said. “We think this region of spike is a critical regulator of whether or not the virus gets into the brain, and it could have large implications for the treatment and management of neurological symptoms reported by COVID-19 patients.” Neurological Symptoms and Long COVID Insights SARS-CoV-2 has long been associated with various neurological symptoms, such as the loss of smell and taste, “brain fog” and “long COVID.” “It’s still not known if long COVID is caused by direct infection of cells in the brain or due to some adverse immune response that persists beyond the infection,” Hultquist said. “If it is caused by infection of cells in the central nervous system, our study suggests there may be specific treatments that could work better than others in clearing the virus from this compartment.” Reference: “Evolution of SARS-CoV-2 in the murine central nervous system drives viral diversification” by Jacob Class, Lacy M.

Heliozoan Raphidocystis contractilis withdraws its axopodia a few milliseconds after encountering an external stimulus. Researchers from Okayama University, Japan report that microtubule dynamics hold the key to this instant arm shortening. Credit: Motonori Ando from Okayama University Researchers have discovered the genes and proteins responsible for the rapid withdrawal of heliozoan arms in response to changes in the environment. This is one of the fastest-known examples of cell motility. Raphidocystis contractilis is a type of eukaryote in the Heliozoa group, found in fresh, brackish, and sea water. These organisms are known as “solar worms” due to their radiating finger-like arms, or axopodia, which give them a sun-like appearance. The axopodia of R. contractilis are made of alpha-beta tubulin heterodimers, which form microtubules. Despite its ability to quickly retract its arms in response to stimuli, the mechanism behind this rapid arm shortening is a mystery. To this end, a team of researchers including Professor Motonori Ando, Dr. Risa Ikeda (both from the Laboratory of Cell Physiology), and Associate Professor Mayuko Hamada (from the Ushimado Marine Institute), of Okayama University, Japan, explored the mechanism involved in one of the fastest cell movements in the living world. So, where did it all begin? Sharing the motivation behind their study, Professor Ando says, “Recently, a wide variety of heliozoans have been discovered in various hydrospheres in the Okayama Prefecture, making it clear that several species of sun worms inhabit the same environment. We are trying to unravel the mysteries around these protozoans and gradually expand the horizons of our knowledge.” Observing Tubulin Dynamics The authors started their investigation by immunolabelling the tubulin protein and observing its movement before and after axopodial contraction. They found that before shortening, tubulins were arranged systematically all along the length of the axopodia, but after axopodial withdrawal, those swiftly accumulated at the cell surface. This led them to believe that during the rapid axopodial withdrawal, the microtubules broke down into tubulin instantly. However, microtubule degradation is generally not a rapid phenomenon; it progresses rather slowly. How then, could R. contractilis achieve this change so quickly? The researchers hypothesized that this was possible if the microtubules split at multiple sites simultaneously. To validate their hypothesis, the authors set out to find the proteins and genes involved in the instant cleavage of microtubules in R. contractilis. Their findings were recently published in The Journal of Eukaryotic Microbiology. The researchers performed de novo transcriptome sequencing (analysis of the genes expressed at a particular time in a cell) and identified close to 32,000 genes in R. contractilis. This gene set was most similar to that found in protozoans (which are single-celled organisms), followed by metazoans (multicellular organisms with well-differentiated cells; this includes humans, and other animals). Key Proteins Identified in Axopodial Retraction Homology and phylogenetic analysis of the obtained gene set revealed several genes (and their corresponding proteins) involved in microtubule disruption. Among these, the most important ones were katanin p60, kinesin, and calcium signaling proteins. Katanin p60 was involved in controlling the axopodial arm length. Several duplicates of kinesin genes were found. Among the identified kinesins, kinesin-13, a major microtubule destabilizing protein, was found to play an important role in the rapid contraction of axopodia. Calcium signaling genes regulate the entry of calcium ions into the cell from its surroundings and the induction of axopodial withdrawal. The researchers also noticed a lack of genes linked with flagellar formation and motility, indicating that the axopodia of R. contractilis have not evolved from flagella. Although many genes remain unclassified, the newly established gene set will serve as a reference for future studies aiming to understand the axopodial motility of R. contractilis. Heliozoan axopodia can function as a sensitive sensor. They can detect minute changes in their environment, e.g., the presence of heavy metal ions and anticancer drugs. Discussing their vision for the future, Professor Ando shares, “We believe that the axopodial response of heliozoa can be used as an index to develop temporary detection and monitoring devices for environmental and tap water pollution. It can also be used as a novel bioassay system for the primary screening of novel anticancer drugs. In the future, we plan to continue to work together as a team to enhance basic and applied research on these organisms.” Heliozoans have proved yet again that a single cell has immense potential to change the world. We wish the authors success in turning their vision to reality!
