This study shows lithium affects behavior and physiology through the gut-brain axis by activating gut enterochromaffin cells, challenging the belief that lithium acts directly on the brain.

The paper identifies shared metabolic trends between degraded soils and T2D gut microbiomes, showing increased sugar metabolism and reduced lignin and branched-chain fatty acid metabolism.

The paper investigates serotonin release mechanisms from mouse enterochromaffin cells using multiple techniques and finds that serotonin is primarily released from large dense-core vesicles with slow kinetics, similar to other endocrine cells.
