Abstract

Use of the acne drug Accutane (13-cis retinoic acid, [13-cis RA]) has been associated with severe depression. This association has been considered controversial because no causative link has been found between 13-cis RA and this disorder. A recent hypothesis has suggested that atrophy of the hippocampus can result in depression. We now show, in a mouse model, that endogenous RA generated by synthetic enzymes in the meninges acts on hippocampal granule neurons, and chronic (3-week) exposure to a clinical dose of 13-cis RA may result in hippocampal cell loss. In humans this may be conjectured to be the mechanism by which Accutane contributes to depression.
