Tau exacerbates excitotoxic brain damage in an animal model of stroke
Nature Communications, 2017 Excitotoxicity contributes to neuronal injury following stroke. Here the authors show that tau promotes excitotoxicity by a post-synaptic mechanism, involving site-specific control of ERK activation, in a mouse model of stroke.

Parkinson's Disease, 2016 A serendipitous pharmacogenetic finding links the vulnerability to developing levodopa-induced dyskinesia to the age of onset of Huntington’s disease. Huntington’s disease is caused by a polyglutamate expansion of the protein huntingtin.

Delayed treatment with nimesulide reduces measures of oxidative stress following global ischemic brain injury in gerbils [PDF]
, 2003 Metabolism of arachidonic acid by cyclooxygenase is one of the primary sources of reactive oxygen species in the ischemic brain. Neuronal overexpression of cyclooxygenase-2 has recently been shown to contribute to neurodegeneration following ischemic ...

Neurodegeneration in multiple sclerosis
WIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023 Chronic demyelination results in impaired axon metabolism and function, ultimately leading to progressive neurological decline. Neuroprotective strategies aim to protect axons from inflammatory‐mediated destruction, thereby improving axonal integrity and clinical disability (Image created in BioRender.com).

Ambient but not local lactate underlies neuronal tolerance to prolonged glucose deprivation [PDF]
, 2018 Neurons require a nearly constant supply of ATP. Glucose is the predominant source of brain ATP, but the direct effects of prolonged glucose deprivation on neuronal viability and function remain unclear.

Brain Pathology, Volume 33, Issue 1, January 2023., 2023 There is no pharmacological treatment available to limit progressing neuronal death after cerebral ischemia. Here we show that targeting the interaction of GABAB receptors with CaMKII using a synthetic interfering peptide after an excitotoxic insult in cultured neurons or in brain slices from MCAO‐treated mice restored downregulated GABAB receptor ...

Bioenergetics and glutamate excitotoxicity
Progress in Neurobiology, 1996 Bioenergetic defects and abnormalities in glutamate neurotransmission have both been proposed to play important roles in neurological diseases of varying chronology, etiology and pathology. Recent experimental evidence suggests an intimate relationship between these two systems.

Imbalance of p75(NTR)/TrkB protein expression in Huntington's disease: Implication for neuroprotective therapies [PDF]
, 2013 Neuroprotective therapies based on brain-derived neurotrophic factor (BDNF) administration have been proposed for Huntington's disease (HD) treatment. However, our group has recently reported reduced levels of TrkB in HD mouse models and HD human brain ...

Brain Pathology, Volume 33, Issue 1, January 2023., 2023 Differential alteration of synaptic versus extrasynaptic NMDARs in P301S mice. Reduced density of synaptic NMDARs in excitatory synapses in the hippocampus of P301S mice at 10 months. NMDARs at excitatory synapses established on pyramidal cell spines and interneurons are significantly reduced in the CA1 region of the hippocampus compared to age‐matched
