The cytokine interleukin (IL) 12 stimulates T cell and natural killer cell production of interferon (IFN) gamma and inhibits T cell production of IL-4. We investigated the effects of IL-12 on cytokine gene expression, immunoglobulin (Ig)E, mucosal mast cell, and eosinophil responses, and the course of infection in mice inoculated with the nematode parasite(More)
Antigens and infectious agents that stimulate interferon alpha(IFN-alpha) production in mice induce antibody responses that are predominantly of the immunoglobulin (Ig)G2a isotype and contain little or no IgE. This suggested the possibility that IFN-alpha might have a role in directing Ig isotype selection. Consistent with this possibility, we have found(More)
