Credit: Chrysanthi Moschandrea Maintaining balanced lipid levels is essential for good health. Consuming too much fatty food can lead to metabolic disorders like obesity and atherosclerosis, but fats are also a vital part of our diet. When digested, lipids provide the body with crucial building blocks and aid in the absorption of vital vitamins. In a new study published in the journal Nature, a team of researchers led by Professor Manolis Pasparakis and their collaborators Professor Aleksandra Trifunovic and Professor Christian Frezza at the Excellence Cluster CECAD of the University of Cologne, and Professor Jörg Heeren at the University of Hamburg, report on a new mechanism that regulates the processing and transport of dietary lipids by the intestine. Mitochondrial Function in Enterocytes The researchers studied the function of mitochondria – organelles acting as powerhouses of the cell – in enterocytes, cells that line the intestine and specialize in the absorption and transport of nutrients from digested food. They found that disruption of mitochondrial function in the intestines of mice caused abnormal accumulation of dietary fat in enterocytes and impaired delivery of lipids to the peripheral organs. A key finding of the study was that, when mitochondria did not function properly, enterocytes showed impaired packaging and transport of lipids in the form of chylomicrons. Chylomicrons are crucial carriers of dietary fats, and their proper formation and transport are essential for the absorption of nutrients. Implications of the Study “This discovery marks a significant leap forward in understanding the crucial role of mitochondria in dietary lipid transport and metabolism,” said Dr Chrysanthi Moschandrea, the lead author of the study. The implications of this discovery go beyond the realm of basic research. “These findings provide new perspectives for the better understanding of the gastrointestinal symptoms in patients suffering from mitochondrial disease, and may also lead to new therapeutic approaches,” added Professor Aleksandra Trifunovic.

Credit: Guillermo Romano Ibarra, University of Iowa Researchers from the University of Iowa demonstrate that pulmonary ionocytes play a key role in the absorption of chloride and water. Researchers from the University of Iowa have discovered that rare lung cells known as pulmonary ionocytes facilitate the absorption of water and salt from the airway surface. This function is exactly the opposite of what was expected of these cells and the findings could impact our understanding of cystic fibrosis (CF) lung disease. Ionocytes in Human Lungs Five years ago, scientists reported the unexpected discovery that ionocytes—a cell type commonly found in fish gills and frog skin—are also present in the lining of human lungs and airways. These pulmonary ionocytes were particularly interesting to CF researchers because although they only account for about 1% of all the cells in the airway lining, they contain about half of the total amount of CFTR, the protein that is dysfunctional in cystic fibrosis.   Despite the implication that CFTR-rich ionocytes might play an important role in CF, the function of these cells has remained unclear.  CFTR Channels and Their Role CFTR channels that are present in airway secretory cells are known to secrete chloride ions out of the cell and into the thin layer of liquid that covers the airway surface. This airway surface liquid plays a vital role in defending the lungs against harmful germs and particles. Because water “follows” salt, the outflow of chloride ions promotes hydration of the airway surface. In contrast, the new study found that CFTR channels in ionocytes do the opposite; they absorb chloride ions and promote moisture absorption.  “The key feature that allows ionocytes to absorb chloride is the ionocyte-specific barttin chloride channel on the opposite membrane of the cell from the CFTR channel,” says Ian Thornell, Ph.D., UI research assistant professor of internal medicine and senior author of the new study published in the Oct.16 issue of The Journal of Clinical Investigation. “Together, these two channels form a conduit for chloride through the ionocyte that helps drain the liquid lining the airways into the body.”   Implications for Cystic Fibrosis The divergent roles of CFTR channels in these two different types of airway cells—ionocytes and secretory cells—also suggests that CF disease disrupts both liquid secretion and absorption, which could have implications for CF lung disease and for how CF drugs affect lung function. Because current CFTR modulator therapies restore CFTR channel function, it is likely that modulators treat both secretion and absorption.   Reference: “CFTR-rich ionocytes mediate chloride absorption across airway epithelia” by Lei Lei, Soumba Traore, Guillermo S.

Scientists have identified crucial sites on the protein CK1δ that regulate our circadian rhythm, potentially offering new ways to treat sleep, metabolic, and other health disorders. A team of scientists from Singapore and the United States discovered how a protein that regulates our biological clock can alter its own function, potentially leading to new treatments for jet lag and seasonal adjustments. Researchers from Duke-NUS Medical School and the University of California, Santa Cruz, have uncovered the key to regulating our internal biological clock. They found that this regulator is located at the tail end of Casein Kinase 1 delta (CK1δ), a protein that serves as a pacemaker for our circadian rhythm—the natural 24-hour cycles that govern sleep-wake patterns and various daily functions. Published in the journal PNAS, their findings could pave the way for new approaches to treating disorders related to our body clock. CK1δ regulates circadian rhythms by tagging other proteins involved in our biological clock to fine-tune the timing of these rhythms. In addition to modifying other proteins, CK1δ itself can be tagged, thereby altering its own ability to regulate the proteins involved in running the body’s internal clock. Previous research identified two distinct versions of CK1δ, known as isoforms δ1 and δ2, which vary by just 16 building blocks or amino acids right at the end of the protein in a part called the C-terminal tail. Yet these small differences significantly impact CK1δ’s function. While it was known that when these proteins are tagged, their ability to regulate the body clock decreases, no one knew exactly how this happened. Unraveling the Mechanism Behind CK1δ Tagging Using advanced spectroscopy and spectrometry techniques to zoom in on the tails, the researchers found that how the proteins are tagged is determined by their distinct tail sequences. Howard Hughes Medical Institute Investigator Professor Carrie Partch from the Department of Chemistry & Biochemistry at the University of California, Santa Cruz and corresponding author of the study explained: “Our findings pinpoint to three specific sites on CK1δ’s tail where phosphate groups can attach, and these sites are crucial for controlling the protein’s activity. When these spots get tagged with a phosphate group, CK1δ becomes less active, which means it doesn’t influence our circadian rhythms as effectively. Using high-resolution analysis, we were able to pinpoint the exact sites involved—and that’s really exciting.” A peptide (shown in mesh) with attached phosphate tags (red and orange spheres) blocks the active site of CK1δ. Tagging the tail end of CK1δ, a process known as auto-phosphorylation, makes the protein less active, and with that less able to fine-tune the body’s internal clocks. Credit: Jon Philpott, Rajesh Narasimamurthy and David Virshup Having first studied this protein more than 30 years ago while investigating its role in cell division, Professor David Virshup, the director of the Cancer and Stem Cell Biology Programme at Duke-NUS and co-corresponding author of the study, elaborated: “With the technology we have available now, we were finally able to get to the bottom of a question that has gone unanswered for more than 25 years. We found that the δ1 tail interacts more extensively with the main part of the protein, leading to greater self-inhibition compared to δ2. This means that δ1 is more tightly regulated by its tail than δ2. When these sites are mutated or removed, δ1 becomes more active, which leads to changes in circadian rhythms. In contrast, δ2 does not have the same regulatory effect from its tail region.” This discovery highlights how a small part of CK1δ can greatly influence its overall activity. This self-regulation is vital for keeping CK1δ activity balanced, which, in turn, helps regulate our circadian rhythms. Broader Implications of the Research The study also addressed the wider implications of these findings. CK1δ plays a role in several important processes beyond circadian rhythms, including cell division, cancer development, and certain neurodegenerative diseases. By better understanding how CK1δ’s activity is regulated, scientists could open new avenues for treating not just circadian rhythm disorders but also a range of conditions. Professor Patrick Tan, Senior Vice-Dean for Research at Duke-NUS, commented: “Regulating our internal clock goes beyond curing jet lag—it’s about improving sleep quality, metabolism, and overall health. This important discovery could potentially open new doors for treatments that could transform how we manage these essential aspects of our daily lives.” The researchers plan to further investigate how real-world factors, such as diet and environmental changes, affect the tagging sites on CK1δ. This could provide insights into how these factors affect circadian rhythms and might lead to practical solutions for managing disruptions.
