abstract：:IL-18 has a potential to up-regulate the Th1 and Th2 immune responses. It is known that IL-18, in synergy with IL-12, augments the Th1 response to bacterial infections, but it also augments the Th2 response to allergic disorders in the absence of IL-12. Although the Th1 and Th2 immune responses cross-regulate each oth...
