abstractText | Infection of nuclear factor of activated T-cell transcription factor c2 (NFATc2)-deficient mice with the helminth Nippostrongylus brasiliensis led to a distinct increase in interleukin-4 (IL-4) and IL-5 protein synthesis by lymph node and spleen cells and to elevated serum immunoglobulin E (IgE) levels in comparison to those seen with infected control mice. While IL-4, IL-5, and IL-13 mRNA expression was also enhanced in lymph node cells from the lungs of infected NFATc2(-/-) mice, the number of T cells secreting Th2-type lymphokines remained the same in mice infected with N. brasiliensis. In contrast, lymphocytes from NFATc2-deficient mice infected with Mycobacterium bovis BCG secreted less gamma interferon than lymphocytes from infected control mice. These findings indicate that NFATc2 is an activator of Th1 responses and a suppressor of Th2 responses in vivo. |
