Fall 2024
Astrocytes can store excess fatty acids in lipid droplets to avoid lipotoxicity. Fatty acids can be released from lipid droplets and catabolized to generate energy in the mitochondria. We previously found reduced astrocytic lipid droplets and increased transport of fatty acids into the...

Background: Diabetes is characterized by dysregulated glucose homeostasis that leads to hyperglycemia, due in part to increased hepatic glucose production (GP) and insulin resistance. Excessive levels and/or action of glucocorticoids (GCs) are associated with obesity, insulin resistance, and...

Postnatal development of the purinergic signaling system in the preBötzinger Complex; implications for the hypoxic ventilatory response
DownloadFall 2023
Low oxygen (hypoxia) evokes the biphasic hypoxic ventilatory response (HVR), in which carotid-body chemoreceptors trigger a rapid increase in ventilation (VE) followed by a centrally-mediated, secondary hypoxic depression of respiration (HRD) and metabolic rate (VO2) that involves adenosine. In...
