microbiome

Gut microbiota can regulate host physiological and pathological status through gut–brain communications or pathways. However, the impact of the gut microbiome on the proteins involved in regulating brain functions and behaviors is still not clearly understood. In a recent publication by Liu et al., the author describes a combined label-free and 10-plex DiLeu-based quantitative method that enabled a comprehensive profiling of gut microbiome that induced dynamic changes, suggesting that the gut microbiome might mediate a range of behavioral changes, brain development, and learning and memory through these neuropeptides and proteins.
