Il-7 Is A Critical Factor In Modulating Lesion Development In Skn-Directed Autoimmunity, Pamela Staton, A. Carpenter, Susan Jackman

In a murine model of autoimmunity targeted against the epidermal cell Ags, Skn, adoptive transfer of Skn-immune T cells to immunosuppressed recipients elicits skin lesions in areas of mild epidermal trauma. In this study, we examined peripheral regulation of Skn-induced autoreactivity disrupted by rendering the mice immunoincompetent. We found that regulation of Skn-directed autoimmunity was restored by cotransfer of normal syngeneic spleen cells at twice the concentration of Skn-immune cells and was evidenced by significantly reduced lesion severity by days 5–7 post-cotransfer compared with animals given injections of Skn-immune cells alone. Enrichment and depletion of normal CD4 or CD8 spleen …
