Potential Therapeutic Interventions Targeting NAD⁺ Metabolism for ALS

Area of Science:

• Neuroscience
• Biochemistry
• Metabolic pathways

Background:

• Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease impacting motor neurons.
• The exact mechanisms driving ALS pathogenesis remain elusive, though factors like oxidative stress are implicated.
• Nicotinamide adenine dinucleotide (NAD+), vital for cellular functions, plays a role in aging and neurodegeneration.

Purpose of the Study:

• To review therapeutic interventions targeting NAD+ metabolism for ALS.
• To evaluate the effects of these interventions on key pathological aspects of ALS in preclinical models.

Main Methods:

• Review of studies investigating NAD+ metabolism in ALS.
• Analysis of therapeutic strategies involving NAD+ precursors and enzyme modulators.
• Examination of data from animal and cell models of ALS.

Main Results:

• NAD+ homeostasis is disrupted in ALS, potentially preceding symptom onset and declining significantly in later stages.
• Treatments aimed at modulating NAD+ metabolism have demonstrated significant benefits in ALS models.
• Interventions include administering NAD+ precursor metabolites and small molecules affecting NAD+-dependent enzymes.

Conclusions:

• Dysregulated NAD+ metabolism is a key feature of ALS.
• Therapeutic strategies targeting NAD+ metabolism hold significant potential for treating ALS.
• Further research into NAD+ pathways may reveal novel therapeutic targets for neurodegenerative diseases.
