Some proteins can help control immune responses in both plants and bacteria. In people, a protein called SARM1 helps break down NAD, which is important for cell energy and can lead to cell death after an injury. This study shows that SARM1 and another protein, TirS, use this ability to lower immune responses and cause a type of cell death that is different from normal cell death.
