Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Examining mechanisms underlying the selective vulnerability of motor units in a mouse model of Spinal Muscular Atrophy [PDF]

, 2014
Spinal Muscular Atrophy (SMA) is a childhood form of motor neuron disease that causes a progressive paralysis that, in its most severe form, results in death before two years of age. There is currently no cure or treatment for SMA.

Biomarkers of disease in a case of familial lower motor neuron ALS

, 2010
ALS is a fatal disease with variable clinical course. There is no single reliable marker of disease progression. Sufficient records were available to study the case history of four family members with the uncommon G93V SOD1 mutation.

Degenerative and regenerative mechanisms governing spinal cord injury

Neurobiology of Disease, 2004
Spinal cord injury (SCI) is a major cause of disability, and at present, there is no universally accepted treatment. The functional decline following SCI is contributed to both direct mechanical injury and secondary pathophysiological mechanisms that are

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Multi-region brain transcriptomic analysis of amyotrophic lateral sclerosis reveals widespread RNA alterations and substantial cerebellum involvement

Molecular Neurodegeneration
Background Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that primarily affects the motor neurons, causing progressive muscle weakness and paralysis.

Advances in nanotechnology-based strategies for the treatments of amyotrophic lateral sclerosis

Materials Today Bio, 2020
Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a progressive neurodegenerative disease that affects both upper and lower motor neurons, which results in loss of muscle control and eventual paralysis [1].

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Motor Neuron Disease (DRAFT)

, 2018
The video in this chapter explores motor neuron disease, including amytrophic lateral sclerosis (ALS) and spinal muscular atrophy (SMA). It discusses the signs of upper motor neuron (UMN) and lower motor neuron (LMN) pathology, as well as Kennedy disease.
