When oxygen levels of the intestine increase, the appropriate hypoxic conditions for intestinal microbiota are lost. This state may be caused by immune-mediated malfunction of the intestinal epithelium. By controlling oxygen levels, the imbalance in the intestinal microbiome (dysbiosis) can be reduced.
Scientists have identified proteins that changed in response to exercise specifically in trial participants whose blood sugar control improved after taking up an exercise regimen. Based on serum protein analysis, the investigators also developed a machine-learning algorithm that could predict whether an individual’s metabolic sensitivity would be improved by exercise.
A study by researchers in Spain suggests that current metagenomic analyses of the microbiome can yield erroneous results, largely due to the incomplete databases that are used to identify microbial DNA sequences. A team led by Clemente Fernández Arias and Federica Bertocchini at the Centro de Investigaciones Biológicas Margarita Salas, Madrid, evaluated current microbiome analysis techniques on computer simulations of microbial communities in a report published on Feb. 8 in PLOS ONE.
A study in a mouse model of tau protein build-up in the brain, similar to that seen in later stage Alzheimer’s disease (AD), shows that changes to the microbiome in these animals can impact the degree and progression of neurodegeneration observed. As reported in the Jan. 12, 2023, study published in Science, the researchers found that mice that were germ free and those given antibiotics to change their gut microbiome early in life had significant reductions in brain atrophy compared with those with a standard microbiome.
Medical College of Wisconsin (MCW) has announced the founding of Rose Biosciences, a biotech company pioneering a new approach to obesity treatment based on a discovery at MCW.
Covira Inc., a spinout from The University of Chicago, has closed its first dilutive funding via an oversubscribed $1.0 million seed round after raising $9.1 million of nondilutive funding.
A metabolite derived from the airway microbiome, indole-3-acetic acid (IAA), could become a potential therapeutic candidate for chronic obstructive pulmonary disease (COPD). Researchers at South China Normal University (SCNU) have shown how IAA prevents lung function decline by reducing inflammation, apoptosis and emphysema through IL-22 in the interaction between macrophages and alveolar epithelial cells.
