Sniffing Out the Truth: Astrocytes Serotonin Processing Plays Essential Role in Olfactory Perception

Researchers shed light on the role of astrocytes, a type of brain cell, in olfactory perception or smell detection. The research reveals that during olfactory stimulation, serotonin transporter Slc22a3 in astrocytes mediates serotonin transport into the cells, influencing gene expression.

Sniffing Out the Mechanism Behind Parkinson’s Smell Loss

Up to 90% of patients report experiencing a diminished sense of smell, even prior to the onset of other symptoms of Parkinson's disease. A new study reveals the mechanism behind smell loss associated with Parkinson's, reporting mouse models with olfactory impairments had severe pathology in projection neurons of the olfactory pathway. The mice also had reduced neurogenesis in the olfactory bulb.
