This molecule could be a candidate for further development as a drug for treating septic shock or autoimmune diseases such as psoriasis and inflammatory bowel disease (IBD) \u2013 but without the side effects typically produced by the currently available anti-inflammatory drugs.<\/p>\n\n\n\n<p>Prof. Karsten Hiller\u2019s team has been doing research for many years on metabolic products that are involved in the human immune system. In 2013, for example, they discovered that immune cells in the blood and brain of mammals produce itaconic acid \u2013 a substance that had only ever been found before as a metabolic product in fungi. Itaconic acid is a natural antibiotic, meaning it fights off bacteria and inhibits inflammations.<\/p>\n\n\n\n<h2 class=\"has-text-align-left wp-block-unilux-blocks-heading\"        id=\"discovery-of-itaconic-acid-opens-new-research-questions\"\n    >\nDiscovery of itaconic acid opens new research questions<\/h2>\n\n\n\n<p>As a result of this discovery, itaconic acid has been the subject of many studies which were also supported within the framework of a binational research project between Prof. Hiller and the research group around the immunologist Prof. Dirk Brenner from the Luxembourg Institute of Health and the University of Luxembourg. During those studies, the researchers discovered that another metabolic product always occurs together with itaconic acid: mesaconic acid. Mesaconic acid is a chemical compound that the body produces from itaconic acid. Hiller relates, \u201cWe were interested in whether mesaconic acid also has an influence on inflammatory responses.\u201d In experiments with laboratory mice, the research team discovered that this is indeed the case: &#8220;Mesaconic acid can revert an immune system that is currently \u201covershooting\u201d back to the normal state\u201d explains Prof. Brenner.<\/p>\n\n\n\n<p>When effects like this are discovered, scientists need to gain a precise understanding of the metabolic processes behind it. In their investigations, a research consortium of nine research groups from Braunschweig, Bonn, Luxembourg, La Jolla (USA) and Arhus (Denmark), found that mesaconic acid has an anti-inflammatory effect of similar strength to that of itaconic acid. \u201cHowever, there is a serious difference,\u201d says Dr. Wei He, a member of Hiller\u2019s team and first author of the study. \u201cUnlike itaconic acid, mesaconic acid does not block the enzyme succinate dehydrogenase. This enzyme plays a central role in cell metabolism.\u201d<\/p>\n\n\n\n<h2 class=\"has-text-align-left wp-block-unilux-blocks-heading\"        id=\"mechanism-of-action-against-an-overactive-immune-system-under-investigation\"\n    >\nMechanism of action against an overactive immune system under investigation<\/h2>\n\n\n\n<p>Succinate dehydrogenase (SDH) is part of the respiratory chain. If it is inhibited \u2013 by itaconic acid, for example \u2013 this has strongly negative effects on metabolism. Since mesaconic acid has anti-inflammatory effects of similar strength to itaconic acid\u2019s, but does not block the enzyme SDH, it makes an especially interesting candidate for an active agent against autoimmune diseases. \u201cWe now investigate why mesaconic acid has a positive anti-inflammatory effect on the immune system. We have already submitted another joint research proposal to do this,&#8221; explain Prof. Hiller and Prof. Brenner<\/p>\n\n\n\n<p>Once the researchers have precise answers to this question, concrete pharmacological investigations into mesaconic acid can begin. \u201cMesaconic acid could be considered for developing into an API for treating diseases in which the immune system is overactive \u2013 septic shock, for example, and especially autoimmune diseases such as psoriasis or inflammatory bowel disease\u201d, says Karsten Hiller. \u201cMaybe even with fewer side effects than other drugs, given that it is a substance that the body produces itself, and which does not interfere with the central metabolic pathways in cells.\u201d<\/p>\n\n\n\n<p>BRICS: Understanding Health<\/p>\n\n\n\n<p>At the Braunschweig Integrated Centre of Systems Biology, BRICS, we want to understand what health means. For this, we investigate the molecular relationships that keep biological systems in balance. At BRICS, scientists use cutting-edge methods to observe biological cells and precisely determine the states of highly complex metabolic networks in their entirety. Using computer-assisted methods in bioinformatics, they identify those factors that cause biological systems to become unbalanced and thus lead to diseases. BRICS then uses the knowledge gained in this way to develop innovative therapies.<\/p>\n\n\n\n<p>BRICS is a joint research centre of the TU Braunschweig, the Helmholtz Centre for Infection Research, and the Leibniz Institute DSMZ \u2013 German Collection of Microorganisms and Cell Cultures GmbH.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.tu-braunschweig.de\/brics\" target=\"_blank\" title=\"\" rel=\"noopener\">www.tu-braunschweig.de\/brics<\/a><\/p>\n\n\n\n<p>About the study<\/p>\n\n\n\n<p>The study was carried out in the research focus &#8220;Infections and Active Substances&#8221; of the TU Braunschweig in BRICS in cooperation with the Luxembourg Institute of Health.
