Inhibiting CD38 raises NAD+ in macrophages from old mice
In cells from old mice, blocking the enzyme CD38 with compound 78c raised NAD+ levels and reduced inflammation and oxidative stress caused by oral pathogens. These are laboratory results, not findings in people.

What the research shows
The study worked with macrophages, a type of immune cell, taken from old mice. The researchers inhibited the enzyme CD38 with compound 78c and observed that NAD+ levels, a molecule linked to cell metabolism, rose. At the same time, inflammation and oxidative stress caused by oral pathogens decreased.
This work builds on the idea that inflammation in immune cells and falling NAD+ levels go along with aging. Still, these results come from mouse cells in a laboratory setting, not from people. They cannot tell us whether the same effect would happen in the human body, or what its safety or usefulness would be.
What it means
The finding suggests that the enzyme CD38 may be a target for research into inflammation linked to aging. It is not yet known whether this works in living animals or in people, or how safe it would be.
How to read it with care
A result in mouse cells does not replace a medical consultation. Anyone considering a change in diet, supplements or treatment should talk to a doctor or another qualified health professional.
