How Gut Bacteria Influence the Effects of Cocaine in Mice

Cocaine use supports the growth of γ-proteobacteria, a common gut bacteria that consume glycine. As glycine levels become depleted mouse models exhibit a higher response to cocaine with abnormal behaviors including increased drug-induced locomotion and drug-seeking behaviors.

Chronic cocaine use modifies gene expression

Chronic cocaine use alters the epigenetic profile of the FosB gene in the hippocampus. These alterations are required for cocaine-dependent gene expression and cocaine environment associations. Modification of hippocampal FosB results in a condition critical for cocaine-related learning.
