“NMN exerts neuroprotective effects after SCI by the regulation of certain genes acting on signaling pathways related to neurological diseases.”

This study found that injection of NMN protected mice from asthma-induced inflammation, mucus production, and lung barrier disruption.
Sepsis-associated disruption of the NRK1/2 pathway for NAD+ synthesis emphasized the critical role of NMN transport through the Slc12a8 transporter.
New research on NAD+ metabolism, NMN supplementation, and mitochondrial NAD+ levels was presented at the esteemed longevity conference, the Aging Research and Drug Discovery (ARDD) Meeting.
“Results from the humanized mouse study demonstrated that NMN treatment could improve the therapeutic effect of cART in vivo on reconstituting CD4+ T cells and improving CD4/CD8 ratio significantly over time.”
“Upon oral administration, NMN–HAP nanoparticles demonstrated prolonged circulation time and enhanced bioavailability compared with free NMN, leading to elevated plasma levels of both NAD+ and its precursor, NR.”
“These results suggest that NMN treatment functionally ameliorated or prevented exacerbation of heart failure in p32 cardiomyocyte–specific knockout mice, thereby prolonging their lifespan.”
“Overall, the present study may shed new light on novel strategies in which NAD+ boosting therapy, including NMN supplement and CD38 inhibition, may turn out to be a promising therapeutic measure to treat patients with hypertension.”
Oral administration of NMN (500 mg/kg) effectively preserved NAD+ tissue and plasma levels during PM exposure and protected against pulmonary fibrosis in mice.
This new study found that for the first time that NMN supplementation in humans increases levels of NMN in blood plasma.
All previous studies with NMN and NR have not been able to detect measurable increase in blood levels of NMN or NR.
They also found increased levels of NAD+ and insulin levels.
“NMN reduced fat mass, which visibly translated into a significantly lower weight of the WAT and BAT in NMN treatment mice.”
“Several human clinical trials indicate that NR and NAM supplementation decrease the risk factors of CVDs, such as hypertension, arterial stiffness, and elevated level of low-density lipoprotein cholesterol 13,14.”
Although NMN has been proven to improve vascular dysfunction in mice, it has not been thoroughly evaluated in humans.
