Brain is particularly vulnerable to toxic effects of reactive oxygen species and a clear correlation between neurodegeneration and oxidative stress has been observed. Iron is an essential element required for many physiological functions, but it is also a key player in oxidative stress induction. Therefore, we aim to characterize the physiological mechanisms of iron handling, both at cellular and mitochondrial level, in primary neurons and glial cells. Moreover, we are employing Induced Pluripotent Stem Cells (iPSCs) to investigate the molecular mechanisms underlying Friedreich’s ataxia, as well as other neurodegenerative disorders characterized by alteration of intracellular iron homeostasis.

Research Activity

1- Mechanisms of iron homeostasis in brain-derived primary cultures

This project is aimed to characterize iron handling and oxidative stress in brain derived primary cultures (neurons, glia). Molecular (gene silencing, RT-qPCR), biochemical (western blotting, subcellular fractionation, cellular assays) and advanced fluorescence optical approaches (Total Internal Reflection Microscopy and High Throughput Microscopy) will be employed, in order to study:

– the expression of molecules involved in intracellular iron import/homeostasis and its modulation under conditions of glial cell activation;

– the mechanisms of iron import and handling in mitochondria;

– the implications of synaptic activity and neuron-glia interaction on neuronal iron homeostasis;

– the evaluation of neurotoxic and the neuroprotective strategies in iron-induced neurodegeneration.

 

2- Role of intracellular iron dysregulation and oxidative stress in Friedreich’s ataxia

Friedreich’s ataxia is an autosomal recessive disease caused by a reduction of expression of frataxin, a ubiquitous mitochondrial protein involved in cellular iron homeostasis. In order to investigate the effects of frataxin deficiency on oxidative stress and neuronal survival, we employ single cell videomicroscopy approaches and fluorescent probes to monitor specific cellular parameters related to iron handling and cytotoxicity. We use neurons and glial cells derived from human Induced Pluripotent Stem Cell (iPSC) to overcome the known limitations of cellular and animal models.
