IL-12 is thought to be involved in the susceptibility to experimental autoimmune encephalomyelitis (EAE), a Th1 cell-mediated autoimmune disorder of the CNS. IL-12 signals through a heterodimeric receptor (IL-12Rbeta1/IL-12Rbeta2), whose beta2-chain is up-regulated on activated, autoreactive Th1 cells. Contrary to the expectation that the absence of IL-12Rbeta2 would protect from EAE, we found that IL-12Rbeta2-deficient mice developed earlier and more severe disease, with extensive demyelination and CNS inflammation. The inflammatory cells were mainly comprised of CD4(+) T cells, monocyte/macrophages, and dendritic cells. Compared to wild-type mice, IL-12Rbeta2-deficient mice exhibited significantly increased autoantigen-induced proliferative response and increased production of TNF-alpha, GM-CSF, IL-17, IL-18/IL-18Ralpha, and NO. In addition, we found significantly increased levels of IL-23p19 mRNA expression in spleen cells from immunized IL-12Rbeta2(-/-) mice compared with wild-type mice. These findings indicate that IL-12 responsiveness is not required in the pathogenesis of inflammatory demyelination in the CNS, and that, in the absence of IL-12Rbeta2, increased IL-23 and other inflammatory molecules may be responsible for increased severity of EAE.
