The Effects Of Circadian Misalignment On Astrocyte Morphology In The Nucleus Tractus Solitarius, Kush C. Patel, Mina Shenouda, Diana Martinez
Rowan-Virtua Research Day
Circadian misalignment, as experienced by shift workers, was found to increase the number of astrocytes in the nucleus tractus solitarius (nTS) - a brain region crucial for autonomic control of blood pressure. Sprague Dawley rats subjected to a 6-hour light-dark phase delay every 2 days to simulate shift work exhibited a significant increase in astrocyte cell bodies compared to control rats, both at 9am and 9pm timepoints. The increase in astrocytes may lead to greater glutamate uptake, reducing extracellular glutamate levels in the nTS. Decreased glutamatergic neurotransmission in this region has been linked to the development of hypertension. These findings …
