Yet, this death process is silent, and it does not cause inflammation. The molecular mechanisms underlying anti-inflammatory nature of the apoptotic process remains poorly understood. In this study, we found that the culture supernatant of apoptotic cells activated the macrophages to express anti-inflammatory genes such as Nr4a and Thbs1. A high level of AMP accumulated in the apoptotic cell supernatant in a Pannexin1-dependent manner. A nucleotidase inhibitor and A2a adenosine receptor antagonist inhibited the apoptotic *For correspondence: snagata@ supernatant-induced gene expression, suggesting AMP was metabolized to adenosine by an mfour.med.kyoto-u.ac.jp ecto-5’-nucleotidase expressed on macrophages, to activate the macrophage A2a adenosine receptor.
