A neuron–glia lipid metabolic cycle couples daily sleep to mitochondrial homeostasis

PR Haynes, ES Pyfrom, Y Li, C Stein… - Nature …, 2024 - nature.com
Sleep is thought to be restorative to brain energy homeostasis, but it is not clear how this is
achieved. We show here that Drosophila glia exhibit a daily cycle of glial mitochondrial …

Glia fuel neurons with locally synthesized ketone bodies to sustain memory under starvation

lead to diseases such as gut dysplasia or metabolic disorders. Several reports have shown …

Amplification is the primary mode of gene-by-sex interaction in complex human traits

C Zhu, MJ Ming, JM Cole, MD Edge, M Kirkpatrick… - Cell Genomics, 2023 - cell.com
Sex differences in complex traits are suspected to be in part due to widespread gene-by-sex
interactions (GxSex), but empirical evidence has been elusive. Here, we infer the mixture of …

Regulating metabolism to shape immune function: Lessons from Drosophila

ML Bland - Seminars in cell & developmental biology, 2023 - Elsevier
