NMNAT1 Protects Injured Axons by Preventing SARM1-Induced NAD+ Loss After Injury: Preclinical Findings

SynopsisOverexpression of the NAD+ biosynthesis enzyme NMNAT1 helps protect injured axons. Although it's believed that higher NAD+ levels or lower NMN levels are important for this protection, the ...

Nicotinamide Riboside Extends Lifespan and Improves Health in Ataxia Telangiectasia Models: Preclinical Findings

SynopsisAtaxia telangiectasia (A-T) is a rare inherited disease causing worsening nerve damage and loss of coordination. It is caused by problems in the ATM gene, which controls how cells repair DN...

NAD+ Metabolism: Energy Production, Signaling Pathways, and Therapeutic Potential: Review

SynopsisVitamin B3's active forms, NAD+ and NADP+, are essential for energy metabolism, cell protection, and biosynthesis. Modern research shows that fluctuations in NAD+ metabolism activate signal...

Nicotinamide Riboside Protects Against Diabetes and Neuropathy: Preclinical Findings

SynopsisMale C57BL/6J mice fed a high-fat diet (HFD) develop prediabetes with insulin resistance and sensory neuropathy. When given low doses of streptozotocin, these mice model type 2 diabetes (T2...

Nicotinamide Riboside Provides Benefit in Amyotrophic Lateral Sclerosis: Preclinical Findings

Synopsis This study explores how boosting nicotinamide adenine dinucleotide (NAD+) metabolism in astrocytes can protect neurons from degeneration in amyotrophic lateral sclerosis (ALS). NAD+ is vi...

NAD+ in Aging, Metabolism, and Neurodegeneration: Review

SynopsisNAD+ is a coenzyme essential for energy production, redox reactions, and as a partner for enzymes like sirtuins and PARPs. Its levels change with age, and altering its production or usage c...

A High-Fat Diet and Increasing NAD+ Rescues Premature Aging in Cockayne Syndrome: Preclinical Findings

Synopsis Cockayne syndrome (CS) is a rare genetic disorder that causes early aging and progressive brain degeneration due to problems in DNA repair genes (CSA or CSB). In mice with the CSB mutatio...

Mitochondrial Dysfunction Linked to NAD+ Decline and DNA Repair Dysfunction: Preclinical Findings

SynopsisMitochondrial problems are common in aging and neurodegenerative diseases. In xeroderma pigmentosum group A (XPA), a disease caused by faulty DNA repair that leads to severe neurodegenerati...

Nicotinamide Riboside Improves Memory and Learning in Alzheimer's Disease: Preclinical Findings

Synopsis NAD+ is an important coenzyme that supports energy production in mitochondria and is linked to longevity and protection against Alzheimer’s disease (AD). Its precursor, nicotinamide ribos...

SIRT1 Activators Like Nicotinamide Riboside Prevent Neuron Damage in Mouse Model of Multiple Sclerosis: Preclinical Findings

Synopsis Axonal damage and neuron loss contribute to permanent vision loss and neurological disability in optic neuritis and multiple sclerosis (MS). Current treatments mainly target inflammation ...

Boosting NAD+ Production Protects Nerves and Slows Axon Degeneration After Injury: Preclinical Findings

Synopsis Axonal degeneration, a major cause of nerve damage in neurodegenerative diseases and after traumatic injury, is a self-destructive process separate from normal cell death. Previous studie...
