| Research Abstract |
In this study, we have investigated the physiological role of PYNOD (a cytoplasmic protein belonging to the NLR family), especially its role in the immune system using PYNOD-deficient mice. PYNOD-deficient mice exhibited a clear defect in the delayed type hypersensitivity that is a type of acquired immune responses, whereas we could find no apparent defect in innate immune responses in these mice. However, draining lymph node cells isolated from PYNOD-deficient mice that had been immunized through skin routes exhibited normal antigen-specific IFN-gamma production, suggesting that peripheral antigen was successfully delivered to draining lymph nodes and effecter T cells were normally generated in these mice. Thus, it is likely that the cause of the defect in the acquired immune system of PYNOD-deficient mice exist in a process of or after the migration of effecter T cells from draining lymph nodes to peripheral tissues.
