Effects of psychological, environmental and physical stressors on the gut microbiota

Alterations in gut microbiota composition have been associated with anxiety behaviors in rodents, but the neural mechanisms connecting microbiota and their metabolites to anxiety are not yet understood. The immediate early c-Fos gene expression in the basolateral amygdala (BLA) significantly increased in male C57BL/6J germ-free (GF) mice in this study by Yu et al. (2025), […]

The proportion of the population that suffers from mental disorders (anxiety and depression, among others) has risen dramatically in the last few years. As a result, finding preventative and treatment methods for mental illnesses is crucial. Several gut microbiota strains, particularly Bacteroidetes, and Firmicutes, have been shown to influence mental health via the microbiota gut-brain […]
