<p>Abstract</p> <p>Scurfy mice display the most severe form of multi-organ inflammation due to total lack of the CD4⁺Foxp3⁺regulatory T cells (Treg) resulted from a mutation of the X-linked transcription factor Foxp3. A large repertoire of Treg-suppressible, inflammation-inducing T cells was demonstrated by adoptive transfer experiments using <it>Rag1</it>^-/-mice as recipients and by prolongation of lifespan through breeding with <it>Fas</it>^{<it>lpr</it>/<it>lpr </it>}mutant. Inflammation in the ear, eyes, skin, tail, salivary glands, lungs, stomach, pancreas, liver, small intestine, colon, skeletal muscle, and accessory reproductive organs are identified. Genetic and cellular regulations of specific organ inflammation are described. Sf mice may be useful for the identification of organ-specific antigens and Treg capable of suppressing inflammation in an organ-specific manner. Sf mice are also useful to determine the important inflammation process at the checkpoint after Treg regulation using genetic analysis through breeding.</p>
