Research Abstract |
T cells exist in the peritoneum under healthy conditions. Rag2Ko mice (T and B cell deficient) showed increased mortality rate during sepsis, which was recovered after adoptive transfer of T cells, but not B cells. Mice with overexpression of SOCS5 in T cells (SOCS5-cTg) demonstrated increased Th1 response in the peritoneum whereas SOCS3-cTg mice exhibited decreased systemic inflammatory response during septic peritonitis, leading to the increased survival rate during sepsis. Thus, T cells appear to be important in innate immunity, which can be controlled by SOCS3/5 in T cells. We also elucidated the crucial roles of T cells in different types of inflammation models, such as T cell-dependent hepatitis and arthritis.
