Spontaneous focal activation of invariant natural killer T cells in the kidney
Focal expression (green-blue) of an interferon-gamma-inducible protein (Irga6) in tubular epithelial cells of the tubular cortex of normal mouse kidney is due to local activation and secretion of interferon gamma by invariant natural killer-like T (iNKT) cells, probably activated by a sporadically expressed endogenous ligand. Similar foci are found in the liver.
