Abstract
Astrocytes rescue neuronal health after cisplatin treatment through mitochondrial transfer.
Author: Krystal English
Advisory Professor: Dr. Cobi J. Heijnen, Ph.D.
Chemotherapy-induced cognitive impairments are associated with neuronal mitochondrial dysfunction. Cisplatin, a commonly used chemotherapeutic, induces neuronal mitochondrial dysfunction in vivo and in vitro. Astrocytes are key players in supporting neuronal development, synaptogenesis, axonal growth, metabolism and, potentially, mitochondrial health. We tested the hypothesis that astrocytes transfer healthy mitochondria to neurons after cisplatin treatment to restore neuronal health.
We used an in vitro system in which astrocytes with Mito-mCherry-labeled mitochondria were co-cultured with primary cortical neurons or neuronal stem …
