15–23 d after tape stripping, each of the histological features was scored singularly and graded 1 to 3 as indicated in Materials and methods; the overall disease score was calculated by combining the scores for each parameter. Data are from three to four different independent experiments (n = 12–30; mean ± SEM).
P < 0.001 as compared with the (NZBxNZW)F1 group.
P < 0.05 as compared with the (NZBxNZW)F1 group.
