Serotonin2A receptor-like immunoreactivity in rat cerebellar Purkinje cells

In the present study we examined the distribution pattern of serotonin2A (5-HT2A) receptors in the rat cerebellum. A strong immunoreaction against 5-HT2A receptor protein was observed in Purkinje cells. A dense cluster of immunopositive dendritic profiles of Purkinje cells was located beneath the pia matter of cerebellar cortex. Somal profiles in the cerebellar nuclei had weak to moderate immunoreactions.
