Abstract TIR8, also known as single Ig IL-1R-related molecule (SIGIRR), is a member of the IL-1 receptor family. The present study was designed to investigate the expression and function of TIR8. TIR8 was mainly expressed in mouse and human epithelial tissues such as kidney, lung and gut. Resting and activated T and B lymphocytes and monocytes-macrophages expressed little or no TIR8, with the exception of the mouse GG2EE macrophage line. In the kidney, the organ with highest mRNA levels, TIR8 expression was confined to epithelial cells and, in situ, to tubular epithelium. A variety of signals More >
