The need for improved specificity and lower toxicity in immune-suppressive drugs for organ transplantation has focused attention on the intracellular signaling pathways that regulate the immune responses of lymphocytes. Among these, the Janus kinase 3 (JAK3) has particular potential, because it mediates signals by several key cytokines, which each utilize a common gamma chain. Changelian et al. developed a highly selective, low-molecular-weight inhibitor of JAK3 that significantly extended organ allograft survival in primate and mouse organ transplant models after oral administration.
