ATP (Adenosine 5-triphosphate) is a central component of energy storage and metabolism in vivo. ATP provides the metabolic energy to drive metabolic pumps and serves as a coenzyme in cells. ATP is an important endogenous signaling molecule in immunity and inflammation. ATP can activate the NLRP3 inflammasome and induce IL-1beta and chemokines secretion. ATP has anti-bacterial infection effects and can protect mice against bacterial infection in mice[1][2][3][4].
