Nebraska chemists have found that a natural, ultra-minor alteration to a molecule can dictate which neuron receptors a neurotransmitter will activate. Though the team discovered the phenomenon in a species of sea slug being held by chemist James Checco, the findings should apply to a range of animals — potentially even humans. Credit: Craig Chandler | University of Nebraska–Lincoln Neurons’ Signaling Can Be Altered by Mirror-Image Molecules With the help of some sea slugs, chemists from the University of Nebraska-Lincoln have found that one of the smallest possible changes to a biomolecule can elicit one of the grandest conceivable consequences: directing the activation of neurons. Their research focused on peptides, which are short chains of amino acids capable of transmitting signals between cells, including neurons. These peptides are present in the central nervous systems and bloodstreams of most animals. An amino acid in a peptide can take on one of two forms, L or D, which consist of the same atoms connected in the same way but arranged in mirror-image orientations. Chemists often think of those two orientations as the left and right hands of a molecule. The L orientation is by far the more common in peptides, to the point of being considered the default. But when enzymes do flip an L to a D, the seemingly minor about-face can turn, say, a potentially therapeutic molecule into a toxic one, or vice versa. A basic rendering of the left and right hands of the same amino acid. Credit: University of Nebraska-Lincoln Flipping L to D: A New Level of Neural Regulation Now, Husker chemists James Checco, Baba Yussif, and Cole Blasing have revealed a whole new role for that molecular mirroring. For the first time, the team has shown that the orientation of a single amino acid — in this case, one of dozens found in the neuropeptide of a sea slug — can dictate the likelihood that the peptide activates one neuron receptor versus another. Because different types of receptors are responsible for different neuronal activities, the finding points to another means by which a brain or nervous system can regulate the labyrinthine, life-sustaining communication among its cells. “We’ve discovered a new way that biology works,” said Checco, assistant professor of chemistry at Nebraska. “It’s nature’s way of helping to make sure that the peptide goes to one signaling pathway versus the other. And understanding more about that biology will help us to be able to take advantage of it for future applications.” Checco’s interest in neuropeptide signaling dates back to his time as a postdoctoral researcher, when he came across the first study to show evidence of a peptide with a D-amino acid activating a neuron receptor in sea slugs. That particular receptor responded to the peptide only when it contained the D-amino acid, making its flip from L to D akin to an on/off switch.

Credit: Craig Chandler | University of Nebraska–Lincoln Eventually, Checco himself would identify a second such receptor. Unlike the one that had initially sparked his interest, Checco’s receptor responded both to a peptide featuring all L-amino acids and the same peptide with a single D. But the receptor was also more responsive to the all-L peptide, activating when introduced to smaller concentrations of it than its D-containing counterpart. Instead of an on/off switch, Checco seemed to have found something closer to a dimmer. “We were left wondering: Is this the whole story?” Checco said. “What’s really going on? Why make this D molecule if it’s even worse at activating the receptor?” A Breakthrough in Understanding Receptor Specificity The team’s newest findings, detailed in the journal Proceedings of the National Academy of Sciences, hint at an answer inspired by a hypothesis. Maybe, the team thought, there were other receptors in the sea slug sensitive to that D-containing peptide. If so, maybe some of those receptors would respond differently to it. Yussif, a doctoral candidate in chemistry, went to work searching for sea slug receptors whose genetic blueprints resembled those of the one Checco had uncovered. He ultimately narrowed down a list of candidates, which the team then cloned and managed to express in cells before introducing them to the same D-containing peptide as before. One of the receptors responded. But this receptor — in an almost mirror-image performance of Checco’s original — responded much more favorably to the D-containing peptide than its all-L peer. “You can see a pretty dramatic shift,” Checco said, “where now the D is, in fact, much more potent than the L at activating this new receptor.” In effect, the team realized, the orientation of that lone amino acid was directing its peptide to activate either one receptor or the other. In its all-L state, the neurotransmitter preferred Checco’s original. When that certain L turned D, on the other hand, it went for Yussif’s new candidate instead. Central nervous systems rely on different types of neurotransmitters to send various signals to various receptors, with dopamine and serotonin among those best-known in humans. Given the radical complexity and delicacy of the signaling in many animals, though, Checco said it makes some sense that they might evolve equally sophisticated ways of fine-tuning the signals sent by even a single neuropeptide. “These sorts of communication processes need to be very, very highly regulated,” Checco said. “You need to make the right molecule. It needs to be released at the right time. It needs to be released at the right site. It needs to degrade, actually, in a certain amount of time, so that you don’t have too much signaling. “So you have all this regulation,” he said, “and now this is a whole new level of it.” Unfortunately for Checco and others like him, naturally occurring peptides that contain D-amino acids are difficult to identify using the instrumentation readily available to most labs. He suspects it’s one reason that, at least to date, no D-containing peptides have been found in people. He also suspects that will change — and that, when it does, it could help researchers better grasp both the function and disease-related dysfunction of signaling in the brain. “I think it is likely that we will find peptides with this kind of modification in humans,” Checco said. “And that’s going to potentially open up new therapeutic avenues in terms of that specific target. Understanding more about how these things are functioning could be exciting there.” In the meantime, Checco, Yussif, and Blasing, a senior double-majoring in biochemistry and chemistry, are busy trying to answer other questions. For starters, they wonder whether an all-L versus D-containing peptide — even those equally likely to activate a receptor — might activate that receptor in different ways, with different cellular consequences. And the search for receptors won’t stop, either. “This is one receptor system, but there are others,” Checco said. “So I think we want to start to extend and discover new receptors for more of these peptides, to really get a bigger picture about how this modification influences signaling and function. “Where I really want to go long-term with this project,” he said, “is to get a better idea, across all of biology, of what this modification does.” Reference: “Endogenous l- to d-amino acid residue isomerization modulates selectivity between distinct neuropeptide receptor family members” by Baba M.

A team of scientists from the University of Tokyo have identified a group of neurons in fruit fly brains responsible for visual aversion to perceived threats. The findings offer potential insights into how humans react to fear, and the team aims to further explore this brain circuitry, which may inform future treatments for anxiety disorders and phobias. A cluster of neurons in the brains of fruit flies has been found to control visual aversion to scary objects. Averting our eyes from things that scare us may be due to a specific cluster of neurons in a visual region of the brain, according to new research at the University of Tokyo. Researchers found that in fruit fly brains, these neurons release a chemical called tachykinin which appears to control the fly’s movement to avoid facing a potential threat. Fruit fly brains can offer a useful analogy for larger mammals, so this research may help us better understand our own human reactions to scary situations and phobias. Next, the team wants to find out how these neurons fit into the wider circuitry of the brain so they can ultimately map out how fear controls vision. Do you cover your eyes during horror movies? Or perhaps the sight of a spider makes you turn and run? Avoiding looking at things that scare us is a common experience, for humans and animals. But what actually makes us avert our gaze from the things we fear? Researchers have found that it may be due to a group of neurons in the brain that regulates vision when feeling afraid. Calm flies wouldn’t show a change in behavior in response to a visual object, but fearful flies would run away from it. Credit: 2023, Tsuji et al. “We discovered a neuronal mechanism by which fear regulates visual aversion in the brains of Drosophila (fruit flies). It appears that a single cluster of 20-30 neurons regulates vision when in a state of fear. Since fear affects vision across animal species, including humans, the mechanism we found may be active in humans as well,” explained Assistant Professor Masato Tsuji from the Department of Biological Sciences at the University of Tokyo. The team used puffs of air to simulate a physical threat and found that the flies’ walking speed increased after being puffed at. The flies also would choose a puff-free route if offered, showing that they perceived the puffs as a threat (or at least preferred to avoid them). Next, the researchers placed a small black object, roughly the size of a spider, 60 degrees to the right or left of the fly. On its own, the object didn’t cause a change in behavior, but when placed following puffs of air, the flies avoided looking at the object and moved so that it was positioned behind them. Tachykinin in Fear-Based Visual Avoidance To understand the molecular mechanism underlying this aversion behavior, the team then used mutated flies in which they altered the activity of certain neurons. While the mutated flies kept their visual and motor functions, and would still avoid the air puffs, they did not respond in the same fearful manner to visually avoid the object. “This suggested that the cluster of neurons which releases the chemical tachykinin was necessary for activating visual aversion,” said Tsuji. “When monitoring the flies’ neuronal activity, we were surprised to find that it occurred through an oscillatory pattern, i.e., the activity went up and down similar to a wave. Neurons typically function by just increasing their activity levels, and reports of oscillating activity are particularly rare in fruit flies because up until recently the technology to detect this at such a small and fast scale didn’t exist.” By giving the flies genetically encoded calcium indicators, the researchers could make the flies’ neurons shine brightly when activated. Thanks to the latest imaging techniques, they then saw the changing, wavelike pattern of light being emitted, which was previously averaged out and missed. Mapping the Brain Circuitry of Fear Next, the team wants to figure out how these neurons fit into the broader circuitry of the brain. Although the neurons exist in a known visual region of the brain, the researchers do not yet know from where the neurons are receiving inputs and to where they are transmitting them, to regulate visual escape from objects perceived as dangerous. “Our next goal is to uncover how visual information is transmitted within the brain, so that we can ultimately draw a complete circuit diagram of how fear regulates vision,” said Tsuji. “One day, our discovery might perhaps provide a clue to help with the treatment of psychiatric disorders stemming from exaggerated fear, such as anxiety disorders and phobias.” Reference: “Threat gates visual aversion via theta activity in Tachykinergic neurons” by Masato Tsuji, Yuto Nishizuka and Kazuo Emoto, 13 July 2023, Nature Communications.

Kyoto University researchers discovered that neutrophils can induce anti-inflammatory macrophages within granulomas, offering potential insights into chronic inflammation and tumor development. This finding could contribute to more effective cancer drug development. Researchers at Kyoto University have found that neutrophils, a type of white blood cell, can induce anti-inflammatory macrophages (M2) within granulomas, which are dense globular structures that form during chronic inflammation. This M2 macrophage polarization can help regulate inflammation and tissue health. The team believes that their findings, derived from studying tuberculosis, could also be applied to tumor development. By understanding how a bacteria-permissive microenvironment is formed, the researchers hope to contribute to more effective cancer drug development. When our bodies become infected, various immune responses are triggered, starting with a release of granulocytes, white blood cells containing special enzymes that makeup about half or more of all human white blood cells. Neutrophils are also granulocytes that fight off invasive bacteria and fungi, often with zero tolerance for such invaders. Sometimes, however, a balanced and less aggressive approach goes even further in providing a cure. Now, a team of researchers at Kyoto University has determined that neutrophils induce anti-inflammatory — or M2 — macrophages deep in the core of the granulomas. In previous studies, chronic inflammatory macrophages were found to have the potential to polarize or differentiate into two opposite versions: pro-inflammatory, or M1, and anti-inflammatory, or M2 types. These constitute an M1-M2 equilibrium that regulates the severity of inflammation and tissue health — or homeostasis. Granulomas and Microenvironment Manipulation This dual nature or polarization describes how M2 can revert to M1 or even M0 — the non-inflammatory or steady state — in the deep granuloma zone where a bacteria-permissive microenvironment is formed. The team has examined the dense globular structures of granulomas in animals, particularly in the lungs. “Microbes and cancer cells may manipulate this permissive microenvironment to favor their survival,” says Tatsuaki Mizutani.

Credit: KyotoU/Tatsuaki Mizutani Human granuloma-related disorders including tuberculosis are a hallmark of chronic inflammatory diseases. Mizutani posits that the results his team obtained from tuberculosis may also be applied to tumors. Previous studies have revealed that intercellular interactions within granulomas drive effective inflammatory responses against pathogens or contaminants, but chronic inflammation — as in tuberculosis and tumors — persists over prolonged periods of time. To test how to predict tumor development, Mizutani’s team previously established a lung granuloma model in guinea pigs, which demonstrated the specific accumulation of Neutrophil S100A9 — or A9 — deep in the cores of granulomas. A9 is expressed in monocytes and macrophages at low levels but at high levels within neutrophils. Applications to Cancer Therapy Development “What is interesting is that both the inflammatory and anti-inflammatory effects of A9 have been reported in A9-deficient mice,” notes Mizutani, whose team is now considering whether to make A9’s multifunctional nature anti-tumorigenic in the tumor microenvironment. “Our understanding of how a permissive microenvironment in tumors is formed may be applied to effective cancer drug development,” reflects Mizutani.
