Nicotinamide Riboside Reduces Brain Inflammation and Cellular Aging in Alzheimer’s Disease: Preclinical Findings

Synopsis In Alzheimer’s disease, brain cells often show low NAD+ levels, high inflammation, and impaired cellular cleanup of damaged components. In mice with Alzheimer’s-like brain changes, five m...

Disrupted NAD+ Metabolism Leads to Brain Defects in Zika Virus-Linked Microcephaly: Preclinical Findings

Synopsis Zika virus (ZIKV) infection during pregnancy can cause microcephaly, a condition where babies are born with abnormally small brains. In this study, researchers analyzed infected mouse bra...

Inhibiting CD38 and Boosting NAD+ with Nicotinamide Riboside Reduces Brain Inflammation: Preclinical Findings

SynopsisNeuroinflammation begins when the brain's innate immune system responds to inflammation. If not properly controlled, this inflammation worsens diseases like multiple sclerosis and Alzheimer...

Nicotinamide Riboside Improves Mitophagy and Reduces Neuroinflammation in Ataxia Telangiectasia: Preclinical Findings

SynopsisIn the premature aging disease ataxia telangiectasia (A-T), cells show mitochondrial dysfunction and a senescence state that causes inflammation (SASP). This is linked to buildup of damaged...

Changes in NMN/NAD+ Ratio Activates SARM1 to Trigger Nerve Damage: Preclinical Findings

SynopsisAxon degeneration is a key feature of many neurodegenerative diseases. SARM1 is an enzyme that breaks down NAD+ and, when activated, causes axon destruction. The enzyme NMNAT2 normally conv...
