NAD+ depletion and defense in bacteria

Depletion of nicotinamide adenine dinucleotide (NAD+), an important regulator of cellular energy metabolism, is a common strategy in immune-mediated cell death (ICD) in both prokaryotes and eukaryotes. Recent studies have revealed how bacteria use NAD+ depletion to protect against phages, providing insight into how eukaryotic ICD might have evolved.
