The researchers were able to monitor the virus’s growth in organoids derived from human intestinal cells. Pink and red show areas of SARS-CoV-2 infection. Credit: Mohammed Shahraz, Sergio Triana/EMBL; Camila Metz-Zumaran/Heidelberg University Scientists transform human intestinal cells into ‘mini guts’ to follow the infection process. In an effort to determine the potential for COVID-19 to begin in a person’s gut, and to better understand how human cells respond to SARS-CoV-2, the scientists used human intestinal cells to create organoids — 3D tissue cultures derived from human cells, which mimic the tissue or organ from which the cells originate. Their conclusions, published in the journal Molecular Systems Biology, indicate the potential for infection to be harbored in a host’s intestines and reveal intricacies in the immune response to SARS-CoV-2. “Previous research had shown that SARS-CoV-2 can infect the gut,” says Theodore Alexandrov, who leads one of the two EMBL groups involved. “However, it remained unclear how intestinal cells mount their immune response to the infection.” In fact, the researchers were able to determine the cell type most severely infected by the virus, how infected cells trigger an immune response, and — most interestingly — that SARS-CoV-2 silences the immune response in infected cells. These findings may shed light on the pathogenesis of SARS-CoV-2 infection in the gut, and indicate why the gut should be considered to fully understand how COVID-19 develops and spreads. According to Sergio Triana, lead author and a doctoral candidate in EMBL’s Alexandrov team, the researchers observed how infected cells seem to start a cascade of events that produce a signaling molecule called interferon. “Interestingly, although most cells in our mini guts had a strong immune response triggered by interferon, SARS-CoV-2-infected cells did not react in the same way and instead presented a strong pro-inflammatory response,” Sergio says. “This suggests that SARS-CoV-2 interferes with the host signaling to disrupt an immune response at the cellular level.” Coronaviruses, including SARS-CoV-2, cause infection by latching on to specific protein receptors found on the surface of certain cell types. Among these receptors is the protein ACE2. Interestingly, the researchers showed that the infection is not explained solely by the presence of ACE2 on the surface of the cells, highlighting our still limited knowledge about COVID-19, even after a year of tremendous research efforts worldwide. As the disease progressed in the organoids, the researchers used single-cell RNA sequencing, which involves several techniques to amplify and detect RNA. Among these single-cell technologies, Targeted Perturb-seq (TAP-seq) provided sensitive detection of SARS-CoV-2 in infected organoids. Lars Steinmetz’s research group at EMBL recently developed TAP-seq, which the researchers combined with powerful computational tools, enabling them to detect, quantify, and compare expression of thousands of genes in single cells within the organoids. “This finding could offer insights into how SARS-CoV-2 protects itself from the immune system and offer alternative ways to treat it,” Lars says. “Further study can help us understand how the virus grows and the various ways it impacts the human immune system.” Reference: “Single-cell analyses reveal SARS-CoV-2 interference with intrinsic immune response in the human gut” by Sergio Triana, Camila Metz-Zumaran, Carlos Ramirez, Carmon Kee, Patricio Doldan, Mohammed Shahraz, Daniel Schraivogel, Andreas R Gschwind, Ashwini K Sharma, Lars M Steinmetz, Carl Herrmann, Theodore Alexandrov, Steeve Boulant and Megan L Stanifer, 27 April 2021, Molecular Systems Biology.

Researchers discovered how valproic acid, a medication commonly used to treat epilepsy, migraines, and bipolar disorder, causes birth defects when taken during pregnancy. Researchers determined that valproic acid prevents nervous system cells from properly developing and dividing When used during pregnancy, the drug valproic acid, which is used to treat bipolar disorder, migraines, and epilepsy, can lead to birth defects. Now, research recently published in the journal PLoS Biology by Bill Keyes of the Institute of Genetics and Molecular and Cellular Biology, France, and associates gives one explanation for why: Valproic acid (VPA) causes certain nervous system development cells to enter a condition known as senescence, which prevents them from properly growing and dividing. VPA is frequently used to treat a variety of diseases. However, since its first use, there have been many instances of pregnant women using VPA giving birth to kids who had birth abnormalities such as spina bifida, facial changes, and heart malformations. A third of exposed newborns also develop cognitive decline and Autism Spectrum Disorder. Three mouse embryos, representative of the study that describes how the teratogenic drug Valproic acid can cause neurodevelopmental birth defects in mice, including microcephaly and exencephaly. The embryo on the left is a normal embryo, with no exposure to Valproic acid. The embryo in the middle is smaller and has microcephaly, while the embryo on the right exhibits exencephaly. The middle embryo and the one on the right were both exposed to Valproic acid. Credit: Muriel Rhinn (CC-BY 4.0) Role of p19Arf in VPA-Induced Developmental Defects Keyes and colleagues examined embryonic exposure to VPA in the new study by using both human organoids—three-dimensional collections of human cells generated in the lab—and mice. They found that neuroepithelial cells, which are the stem cells that give rise to the central nervous system, undergo cellular senescence as a result of VPA. The researchers also identified p19Arf as the specific molecule that caused this VPA-induced senescence. Although VPA exposure during pregnancy still resulted in other abnormalities, the scientists found that it no longer produced microcephaly (a small head size) or alterations to gene expression patterns linked to autism spectrum disorder in mice missing the p19Arf gene. Valproic acid is used to treat the manic phase of bipolar disorder, seizures, and migraine headaches. This prescription medication goes by various brand names including Depakene, Depakote, Depakote DR, Depakote ER, Depakote Sprinkles, Stavzor, and Alti-Valproic. The work is one of the first to associate cellular senescence with developmental defects, the authors say. “Overall, the discovery that atypical activation of senescence in the embryo can perturb development raises the intriguing possibility that it may also contribute to defects in developmental contexts beyond those we studied here.” Muriel Rhinn, the first author of the study, adds, “While cellular senescence has long been associated with aging and age-related disease, we now show that aberrant induction of senescence can also contribute to developmental defects. As valproic acid is strongly linked to cognitive defects and Autism Spectrum Disorder, this study now introduces an exciting link with senescence, supporting how additional studies are needed.” This study was funded by grants from La Fondation pour la Recherche Medicale (FRM) (AJE20160635985), Fondation ARC pour la Recherche sur le Cancer (PJA20181208104), IDEX Attractivité – University of Strasbourg (IDEX2017), La Fondation Schlumberger pour l’Education et la Recherche FSER 19 (Year 2018)/FRM, Agence Nationale de la Recherche (ANR) (ANR-19-CE13-0023-03) and Ligue Contre le Cancer (all to W.M.K.).

This work is licensed under CC BY-NC. International study shows that freshwater polluted by fecal material can be determined more quickly and reliably using a new technique. When wastewater from villages and cities flows into rivers and lakes, large quantities of fats, proteins, sugars, and other carbon-containing, organic substances wind up in nature together with the fecal matter. These organic substances are broken down by bacteria that consume oxygen. The larger the volume of wastewater, the better the bacteria thrive. This, however, means the oxygen content of the water continues to decrease until finally the fish, mussels, or worms literally run out of air. This has created low-oxygen death zones in many rivers and lakes around the world. No gold standard for measurements until now In order to measure how heavily the waters are polluted with organic matter from feces, government bodies and environmental researchers regularly take water samples. One widely used measurement method uses a chemical reaction to determine the content of organic substances. As an international team of scientists now shows, this established method provides values from which the actual degree of the water pollution can hardly be derived. Prof. Helmuth Thomas, Director of Hereon’s Institute of Carbon Cycles is also a contributor to the study, which has now been published in the scientific journal Science Advances. “In the paper, we are therefore also introducing a new method for making the measurements much more reliable in the future,” he says. Using the conventional measurement method, water samples are mixed with the chemicals permanganate or dichromate. These are especially reactive and break down all organic substances in a short time. The quantity of consumed permanganates or dichromates can then be used to determine how much organic substance was contained in the water sample. Experts refer to this measurement as “chemical oxygen demand,” COD. The problem with the COD measurements is that they do not differentiate between the organic substances that wind up in the water with the sewage, and those that arise naturally — such as lignin and humic acids — which are released when wood decays. This means that the water pollution can hardly be distinguished from the natural content of organic substances. “For the Han River in South Korea, for example, we have shown that the pollution with organic substances from wastewater in the past twenty-five years has decreased. The COD measurements, however, still show high values as they were before,” says Helmuth Thomas, “because here the natural substances make up a large portion of the organic matter in the water.” Complicated biological analysis But how can the actual pollution be measured more reliably? A biological measurement method has been established here for decades, but it is much more complex than the COD method and is therefore used more seldomly by government bodies and research institutions. In this case, a water sample is taken from the river or lake and the oxygen content of the water is measured as an initial value. Another “parallel sample” is immediately sealed airtight. Then this water sample rests for five days. During this time, the bacteria break down the organic substance, whereby they gradually consume the oxygen in the water. After five days, the container is opened and the oxygen is measured. If the water contains a great deal of organic matter, then the bacteria were particularly active. The oxygen consumption was then correspondingly high. Experts refer to the “biological oxygen demand” (BOD) in this measurement. “The BOD measurement is far more precise than the COD because the bacteria preferentially break down the small organic molecules from the wastewater but leave the natural ones, such as lignin, untouched,” says Thomas. Nevertheless, the BOD measurement has its disadvantages, too. On the one hand, the BOD measurement takes five days, while the COD value is available after a few minutes. On the other, while filling, storing, and measuring the water samples, meticulous care must be taken to ensure that no oxygen from the ambient air winds up in the sample and falsifies the measurement value. “Only a few people with a great deal of laboratory experience have mastered how to entirely handle the BOD measurement,” says Thomas. “Therefore, government bodies and researchers even today still prefer the COD despite its greater uncertainties.” Faster and more reliable method Helmuth Thomas and his team are therefore introducing an alternative method that improves on the conventional BOD measurement. The advantage to the method is that only one water sample is necessary, which is immediately sealed and the oxygen consumption is measured without interfering with the sample. It is therefore unnecessary to open the sample after five days again to measure the oxygen content. This prevents the sample from coming into contact with atmospheric oxygen again. With the new approach, an optical fiber is inserted into the sample vessel as soon as the water sample is filled. Through this fiber, the oxygen content can be continuously measured directly in the sample using optical effects. Thomas says, “We can measure the oxygen content non-stop and obtain a far more precise picture of the oxygen consumption by the bacteria.” First tests have shown that a meaningful result is already available after about forty-eight hours, something that considerably accelerates the BOD measurement. All in all, the optical method makes the BOD measurements not only more reliable, but also faster. Helmuth Thomas assumes that the new method in the coming years therefore will be established as the new standard, which will replace both the COD as well as the classic BOD measurements. In the future, for example, it will be possible to determine more reliably than before whether water pollution control measures are actually successful.
