5-HT6 receptor antagonists as treatment for age-related cognitive decline.

The 5-HT6 receptor (5-HT6R) is one of the most recently discovered serotonin
receptors and has received much attention after observations showing its
procognition properties. Indeed, 5-HT6R appears to be a promising target to treat
cognitive decline, particularly via its modulatory function of cholinergic and
glutamatergic systems. 5-HT6Rs are present mostly in the central nervous system,
in brain structures known to be particularly involved in memory. Growing evidence
suggests that blockade of 5-HT6R can not only improve memory processes in adult
rodents but also reverse age-related and pharmacologically induced deficits.
5-HT6R blockade could also have a beneficial effect on neuronal plasticity.
Regarding these findings, several 5-HT6R antagonists are currently going through
clinical trials. This review provides an overview of the major findings arguing
in favour of a role for 5-HT6R antagonists in developing treatment for cognitive
disorders related to ageing and neurodegenerative diseases.
