This important study provides solid evidence, both from biochemical analyses and in vivo mouse models, that soluble uric acid serves as an enzymatic inhibitor of the NADase CD38, thereby impacting inflammatory responses. By shedding light onto the intricate interplay between uric acid and CD38, the authors highlight potential therapeutic avenues for inflammatory and age-related conditions, which may be of interest to medical biologists, biochemists, and cell biologists. Further in vivo and in vitro validation suggested would be helpful to cement the significance and implications of these findings.
