The Microbiota Shapes Central Nervous System Myelination in Early Life

Advanced Science, EarlyView.
Gut microbiota shapes brain development by regulating myelination and glial cell maturation in early life. Using germ‐free (GF) mice and zebrafish, this study reveals sex‐ and age‐dependent effects on myelin growth, integrity, and related gene expression.

Gut Microbe‐Driven Resistance Mechanisms in Propylea Japonica: Insights from Horizontal Gene Transfer and Oxidative Phosphorylation

Advanced Science, EarlyView.
Acinetobacter regulates dinotefuran tolerance in Propylea japonica by mediating the expression of the horizontally transferred gene PjDUF1. Abstract Insect–microbial symbiont relationships are widespread in nature and often involve lateral gene transfer.
