Serotonin deficiency implicated in rheumatoid arthritis

For the first time, serotonin (5-hydroxytryptamine, 5-HT) has been directly implicated in the pathophysiology of rheumatoid arthritis (RA). A new report shows that experimentally-induced RA in serotonin-deficient mice is worse than disease reported in controls and that some effects of RA can be reduced by serotonin or its agonists (compounds that activate serotonin receptors).
