1 Post-translational processing of murine IL-1: evidence that ATP-induced release of IL-1 alpha and IL-1 beta occurs via a similar mechanism. Adenosine Triphosphate interleukin 1 beta Mus musculus
2 Externalization and proteolytic processing of pro-IL-1 beta can be initiated by extracellular ATP. Adenosine Triphosphate interleukin 1 beta Mus musculus
3 Proteolysis of pro-IL-1 beta initiates within 7.5 min of ATP addition; 17-kDa mature IL-1 beta is observed first intracellularly and subsequently extracellularly. Adenosine Triphosphate interleukin 1 beta Mus musculus
4 Macrophages exposed to ATP continuously or only for a 15-min pulse release IL-1 alpha, IL-1 beta, and lactate dehydrogenase (LDH). Adenosine Triphosphate interleukin 1 beta Mus musculus
5 Ethacrynic acid and DIDS (4,4"-diisothiocyanato-stilbene-2,2"-disulfonic acid) block ATP-induced proteolysis of pro-IL-1 beta and prevent release of pro-IL-1 alpha/beta and LDH; they do not inhibit ATP-induced K+ (86Rb+) efflux. Adenosine Triphosphate interleukin 1 beta Mus musculus
6 These results indicate that ATP stimulates externalization of both IL-1 alpha and IL-1 beta. Adenosine Triphosphate interleukin 1 beta Mus musculus
