Oligodendrocytes contribute to motor neuron death in ALS via SOD1 dependent mechanism [PDF]

, 2016
Oligodendrocytes have recently been implicated in the pathophysiology of ALS. Here we show that, in vitro, mutant SOD1 mouse oligodendrocytes induce wild-type motor neuron hyperexcitability and death.

The role of lipid metabolism in neuronal senescence

FEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Trophic factors as modulators of motor neuron physiology and survival: implications for ALS therapy

Frontiers in Cellular Neuroscience, 2014
Motor neuron physiology and development depend on a continuous and tightly regulated trophic support from a variety of cellular sources. Trophic factors guide the generation and positioning of motor neurons during every stage of the developmental process.

The Huntington's disease mutation impairs Huntingtin's role in the transport of NF-κB from the synapse to the nucleus [PDF]

, 2010
Expansion of a polyglutamine (polyQ) tract in the Huntingtin (Htt) protein causes Huntington's disease (HD), a fatal inherited neurodegenerative disorder.

Microglial dynamics and ferroptosis induction in human iPSC‐derived neuron–astrocyte–microglia tri‐cultures

FEBS Open Bio, EarlyView.
A tri‐culture of iPSC‐derived neurons, astrocytes, and microglia treated with ferroptosis inducers as an Induced ferroptosis model was characterized by scRNA‐seq, cell survival, and cytokine release assays. This analysis revealed diverse microglial transcriptomic changes, indicating that the system captures key aspects of the complex cellular ...

The critical role of membralin in postnatal motor neuron survival and disease

eLife, 2015
Hitherto, membralin has been a protein of unknown function. Here, we show that membralin mutant mice manifest a severe and early-onset motor neuron disease in an autosomal recessive manner, dying by postnatal day 5–6.

Local BDNF Delivery to the Injured Cervical Spinal Cord using an Engineered Hydrogel Enhances Diaphragmatic Respiratory Function. [PDF]

, 2018
We developed an innovative biomaterial-based approach to repair the critical neural circuitry that controls diaphragm activation by locally delivering brain-derived neurotrophic factor (BDNF) to injured cervical spinal cord.

Phrenic Motor Neuron Survival Caudal to C2 Hemisection

The FASEB Journal, 2017
Cervical spinal injury (cSCI) severs descending brainstem projections to spinal respiratory motor neurons, paralyzing respiratory muscles caudal to injury. Spinal hemisection at C2 (C2Hx) has frequently been used as an experimental model of cSCI to study both spontaneous and induced functional recovery of both respiratory and non‐respiratory somatic ...

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells

FEBS Open Bio, EarlyView.
Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

AAV-based delivery of RNAi targeting ataxin-2 improves survival and pathology in TDP-43 mice

Nature Communications
Amyotrophic lateral sclerosis (ALS) involves motor neuron death due to mislocalized TDP-43. Pathologic TDP-43 associates with stress granules (SGs), and lowering the SG-associated protein ataxin-2 (ATXN2) using Atxn2-targeting antisense oligonucleotides ...
