The Department of Neurochemistry studies molecular mechanisms that regulate the function of glutamate receptors in the mammalian central nervous system. We also aim to develop novel pharmacological compounds that act on glutamate receptors for the treatment of cognitive decline caused by neurodegeneration. Our experimental approach includes microscopy, biochemistry, and electrophysiology in cultured hippocampal neurones and human fibroblasts derived from patients with neurodegenerative diseases. Our long-term goal is to develop “personalised” compounds for treating specific neurodegenerative conditions including Alzheimer disease.
