Happy Wednesday! Today’s digest includes two gut-brain axis papers from Sarkis Mazmanian’s lab at CalTech. The first article, published in Nature, found that 4-ethylphenol (4EPS) produced by gut microbes from dietary tyrosine was capable of entering the brain and changing gene expression, brain cell interactions, and brain functions. In the second study, published in Nature Medicine, oral administration of the adsorbent AB-2004–which can bind and sequester phenolic compounds–led to reduced levels of gut 4EPS and decreased anxiety in human adolescents with autism spectrum disorder.

I have also included an article published by my thesis lab in The Journal of Allergy and Clinical Immunology looking at the impact of seasons on the respiratory microbiome and asthma exacerbations in children.

Finally, there is an interesting paper by Baranova et al. in which the authors identify a bacterial species ubiquitous across multiple wild animals that appears to have novel functions for pathogen control or microbiome remodeling. Happy reading!

Today’s digest covers a range of topics including a duplex qPCR assay to detect lung infections, an investigation into sand fly symbionts, and a characterization of a fermented soybean food (Pe poke). If you want to end the week on a good note, I’d suggest reading the two articles I’ve highlighted below. One demonstrates that flooding and ecological restoration of former cranberry farmland also restores wetland microbial communities and soil function. The second provides a new barcoding strategy for the phenotypic screening of mosquitos that can be applied towards malaria research.
