Astrocytes protect neurons and oligodendrocytes by buffering ions, neurotransmitters, and providing metabolic support. However, astrocytes are also vulnerable to oxidative stress, which may affect their protective and supportive functions. This paper examines the influence of calcium and iron on ast

## Abstract Uncoupling proteins (UCPs) uncouple oxidative phosphorylation from ATP synthesis by dissipating proton gradient across mitochondrial inner membrane. The physiological role of neuronal specific UCP5 is unknown. We explored the effects of reduced UCP5 expression on mitochondrial membrane
