Figure 9. p21 overexpression reduces autoimmune disease symptoms and mortality in MRL/lpr mice.

Figure 9

(a) Relative anti-DNA IgG levels detected by ELISA in serum at 4 months of age. Anti-DNA IgG production was decreased in MRL/lpr-p21tg compared to MRL/lpr mice. Values show mean ± SD (n = 9 mice; p < 2 × 10−4). (b) Immunostaining of kidney cryosections, showing reduced immune complex deposition (anti-IgG), CD4+ T cell (anti-CD4) and macrophage (anti-F4/80) infiltration in MRL/lpr-p21tg mice at 6 months of age. (c) Evaluation of glomerulonephritis grade (Berdem scale) in representative kidney sections from MRL-Mp, MRL/lpr and MRL/lpr-p21tg mice at 6 months of age showed reduced glomerulonephritis in MRL/lpr-p21tg than in MRL/lpr mice. (d) Kaplan-Meier survival curves indicate the effect of the p21 transgene on MRL/lpr-p21tg mouse lifespan.
