Kidney pathology of experimental lupus nephritis is ameliorated by treatment with alpha-galactosylceramide (α-GalCer). Representative images of periodic acid-Schiff staining of kidney slices in the (a) vehicle and (b) α-GalCer groups. Arrows, immune complex deposits; arrowhead, segmentally sclerotic area. The percentages of (c) glomeruli with immune complex deposits, (d) sclerotic glomeruli, and (e) glomeruli with crescents in each group (vehicle group; n = 5, α-GalCer group; n = 7). *p < 0.05 compared with the vehicle group.
