Researchers, including Prof MDR's @MarcEDumas, have discovered that chemicals produced by gut bacteria could act as an early warning system for future heart disease, potentially allowing doctors to identify at-risk individuals years before symptoms appear imperial.ac.uk/news/articlesโ€ฆ

Honoured to see our @NatureMetabolism study featured on the Ottawa Citizen front page today. We found a gut-made molecule (TMA), can switch off inflammation linked to diabetes through IRAK4. New Year tip: eat your broccoli ๐ŸฅฆWonderful collabor'n with Prof Dumas @imperialcollege .

The article in the Citizen ottawacitizen.com/news/localโ€ฆ showed that gut microbiome can convert choline in legumes, broccoli or salmon to nature's solution to inflammation. @HeartInstitute @imperialcollege @MarcEDumas nature.com/articles/s42255-0โ€ฆ

These drugs also improve kidney function, reduce the risk of fatal cardiac events, and are linked to protection against neurodegeneration. ๐Ÿคขย However, many people stop taking the drugs due to common side effects, including nausea and vomiting. Studies also show that incretin-based therapies like Wegovy and Mounjaro are much less effective at lowering weight in people living with both obesity and type 2 diabetes โ€“ a group numbering more than 380 million people globally. ๐Ÿ”ฅย In a study published in @Nature, an international team of scientists describe a powerful new drug candidate that lowers appetite without loss of muscle mass or side effects like nausea and vomiting. And, unlike the current generation of treatments, the drug also increases the bodyโ€™s energy expenditure โ€“ the capacity of the body to burn calories. ๐Ÿ’ฌย "While GLP-1-based therapies have revolutionized patient care for obesity and type 2 diabetes, safely harnessing energy expenditure and controlling appetite without nausea remain two Holy Grails in this field. By addressing these needs, we believe our discovery will propel current approaches to make more tolerable, effective treatments accessible to millions more individuals,โ€ says Associate Professor @Z_GerhartHines Gerhart-Hines from the NNF Center for Basic Metabolic Research (CBMR) at the University of Copenhagen.

Truely Fantastic work by @Z_GerhartHines and your @Metabolcenter and Embark Biotech teams over almost 10 years to identify our old NK2R as a cardiometabolic target to hit 1) energy expenditure 2) food intake and - importantly - 3) insulin sensitivity. So Proud. Move over #wegovy.
Our new paper, "NK2R control of energy expenditure and feeding to treat metabolic diseases," is out today in @Nature. Here we identify a single receptor that can both peripherally increase energy expenditure and centrally suppress appetite. nature.com/articles/s41586-0โ€ฆ 1/12 ๐Ÿงต๐Ÿ‘‡
