VALT shows lymphoid follicular and germinal center activity. (A) Different gene transcripts related to lymphoid follicular and germinal center activity in MRL and LPR mice at 6 months of age. Microarray analysis, significant difference from the control is indicated by * (*P < 0.05, **P < 01, 2-tailed Student’s t test). n = 3. (B) CD21+ follicular dendritic cells (arrows) in VALT of LPR mice at 6 months of age (IHC). (C) CD138+ plasma cells (arrows) in VALT of LPR mice at 6 months of age (IHC). (D) IgM+ cells (arrows) in VALT of LPR mice at 6 months of age (IHC). (E) IgG+ cells (arrows) in VALT of LPR mice at 6 months of age (IHC). Bars = 100 µm. VALT, vasculature-associated lymphoid tissue; IHC, immunohistochemistry.
