Figure 1 Comparison of the glomerular immune deposits composition associated with IgA+PnC in BCD and WT mice. Representative immunofluorescence micrographs of IgA, IgG, IgM, and C3 in the kidneys at day 14 treatment of (a–d) BCD and (e–h) WT mice with IgA+PnC are compared to (i–l) BCD mice and (m–p) WT mice that received PnC only. Original magnification × 400. (q) Semiquantitative analysis of the immunofluorescence intensity in renal tissues of the experimental groups of BCD and WT mice treated with IgA+PnC. *P<0.05; **P<0.005.
