abstractText | We have analyzed the effect of IL2 administered in vivo on both the lymphoproliferation and autoimmune disease progression of MRL/lpr mice. Human IL2 was delivered by infecting MRL/lpr mice with vaccinia virus recombinants at different stages of lpr disease. The results reported here showed that treatment of lpr mice with IL2 mediated: (1) restored normal thymic differentiation illustrated by an expansion of the double positive population accompanied by increased numbers of mature thymocytes; (2) depletion of the peripheral CD3+ CD4- CD8- (DN) T-cell population; (3) normalization in the pattern of TcRV beta gene expression displayed by mature T cells; (4) decreased urine-protein levels and immune complex deposition in the kidney, with a resultant absence of glomerulonephritis; and (5) an increased longevity (from 195 to more than 400 days). We speculate that the dramatic reduction in the abnormally expanded CD3+ DN T-cell population following IL2 therapy might be directly related to the amelioration and/or prevention of autoimmune disease in these mice. Collectively, these results suggest that diseases showing a selective expansion of DN cells should be envisaged as possible targets for the treatment described here. |
