Nicotinamide riboside and caffeine partially restore diminished NAD availability but not altered energy metabolism in Alzheimer's disease

Aging Cell, Volume 21, Issue 7, July 2022., 2022
Nicotinamide riboside (NR) and caffeine increase nicotinamide adenine dinucleotide (NAD), transiently modulate bioenergetic functions, and change the expression of NAD‐synthesizing, recycling, or degrading genes in dermal fibroblasts or induced pluripotent stem cell (iPSC)‐derived neural progenitors and astrocytes from late‐onset Alzheimer's disease ...

CD38 in Neurodegeneration and Neuroinflammation

Cells, 2020
Neurodegenerative diseases are characterized by neuronal degeneration as well as neuroinflammation. While CD38 is strongly expressed in brain cells including neurons, astrocytes as well as microglial cells, the role played by CD38 in neurodegeneration ...

CD38 Drives Progress of Osteoarthritis by Affecting Cartilage Homeostasis

Orthopaedic Surgery, Volume 14, Issue 5, Page 946-954, May 2022., 2022
CD38 is a membrane‐bound protein. This study primarily implicates CD38 as an important regulator of chondrogenic differentiation. Inhibition of CD38 demonstrated protection against cartilage degeneration, which suggests that CD38 could be a potential therapeutic target for OA.

NAD+ improves cognitive function and reduces neuroinflammation by ameliorating mitochondrial damage and decreasing ROS production in chronic cerebral hypoperfusion models through Sirt1/PGC-1α pathway

Journal of Neuroinflammation, 2021
Microglial-mediated neuroinflammation plays an important role in vascular dementia, and modulating neuroinflammation has emerged as a promising treatment target. Nicotinamide adenine dinucleotide (NAD+) shows anti-inflammatory and anti-oxidant effects in

CD38 inhibitor 78c increases mice lifespan and healthspan in a model of chronological aging

Aging Cell, Volume 21, Issue 4, April 2022., 2022
The NADase CD38 plays a key role in age‐related NAD decline. The CD38 inhibitor 78c increases lifespan and healthspan of naturally aged male mice. The increase in median and maximal lifespan was about 10%. Abstract Nicotinamide adenine dinucleotide (NAD) levels decline during aging, contributing to physical and metabolic dysfunction.

Nicotinamide pathways as the root cause of sepsis – an evolutionary perspective on macrophage energetic shifts

The FEBS Journal, Volume 289, Issue 4, Page 955-964, February 2022., 2022
Increased IDO activity towards de novo nicotinamide synthesis is a hallmark of alternatively activated macrophages. IDO upregulation in alternatively activated macrophages may be an attempt to compensate for insufficient NAD availability. Manipulation of nicotinamide metabolism may shift macrophage metabolism, thereby providing a therapeutic approach ...
