abstractText | Serotonin (5-HT) is known to reduce apoptosis and in rodent models of brain ischemia. Modulation of programmed cell death during neural development was assessed in early postnatal brains of serotonin transporter (5-HTT) knockout mice, characterized by elevated extracellular 5-HT levels. The number of apoptotic cells visualized at postnatal day-1 (P1) by ISEL+ or TUNEL staining was significantly reduced in the striatum, thalamus/hypothalamus, cerebral cortex and hippocampus of 5-HTT knockout mice, compared to wild type and heterozygote mice, with differences displaying an increasing fronto-caudal gradient and regional specificity. These findings underscore 5-HT roles in the regulation of programmed cell death during brain development, and spur interest into pharmacological interventions aimed at relieving pathological apoptosis by potentiating serotoninergic neurotransmission. |
