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

open access: yesAging 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 Drives Progress of Osteoarthritis by Affecting Cartilage Homeostasis

open access: yesOrthopaedic 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.

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

open access: yesAging 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

open access: yesThe 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 ...

Structural and catalytic characterization of Blastochloris viridis and Pseudomonas aeruginosa homospermidine synthases supports the essential role of cation–π interaction

open access: yesActa Crystallographica Section D, Volume 77, Issue 10, Page 1317-1335, October 2021., 2021
The homospermidine synthases from P. aeruginosa and B. viridis, as well as their single‐residue variants, are compared based on crystal structures and activity assays. A high structural similarity is demonstrated, suggesting the equivalent involvement of relevant residues in the reaction mechanism and catalytic dependence on cation–π interaction ...

The new insight into extracellular NAD+ degradation‐the contribution of CD38 and CD73 in calcific aortic valve disease

open access: yesJournal of Cellular and Molecular Medicine, Volume 25, Issue 13, Page 5884-5898, July 2021., 2021
Abstract Nicotinamide adenine dinucleotide (NAD+) is crucial for cell energy metabolism and many signalling processes. Recently, we proved the role of ecto‐enzymes in controlling adenine nucleotide–dependent pathways during calcific aortic valve disease (CAVD).

It takes two to tango: NAD+ and sirtuins in aging/longevity control [PDF]

open access: yes, 2016
The coupling of nicotinamide adenine dinucleotide (NAD+) breakdown and protein deacylation is a unique feature of the family of proteins called ‘sirtuins.’ This intimate connection between NAD+ and sirtuins has an ancient origin and provides a ...

Development of the Cerebrospinal Fluid in Early Stage after Hemorrhage in the Central Nervous System

open access: yesLife, 2021
Extravasation of blood in the central nervous system (CNS) represents a very strong damaged associated molecular patterns (DAMP) which is followed by rapid inflammation and can participate in worse outcome of patients.
