Figure Lengend Snippet: Comparison of M cell and follicular dendritic cell (FDC) status in the secondary lymphoid tissues of CXCR5 ΔDC mice and CXCR5 F/F control mice. (A) Peyer's patches were whole-mount immunostained to detect M cells (GP2 + cells, green). F-actin (blue) was used as a counterstain. The broken line indicates the boundary of the follicle associated epithelium (FAE). V, villi. (B) The number of GP2 + M cells/FAE was similar in Peyer's patches from each mouse group ( P = 0.710). (C) Morphometric analysis suggested the size of the FAE area was also similar in each mouse group ( P = 0.265 [Student t test]; data were derived from 2 to 20 FAE/mouse [ n = 6 to 8 mice/group]). IHC comparisons of CD35 (magenta) and PrP C (green) expression by FDC in the Peyer's patches (D), mesenteric lymph nodes (MLN) (G), and spleens (J) of CXCR5 F/F and CXCR5 ΔDC mice are shown. The sizes of the FDC in the Peyer's patches (E), MLN (H), and (K) spleens of mice from each group were estimated by morphometric analysis of the area of CD35 + immunostaining. The abundance of PrP C expressed by the FDC in Peyer's patches (F), MLN (I), or spleens (L) from each mouse group was estimated by morphometric analysis of the number of PrP C+ pixels within each FDC network. Data were derived from 2 to 10 FDC/mouse ( n = 6 to 8 mice/group).
Article Snippet: Briefly, Peyer's patches were fixed with BD Cytofix/Cytoperm (BD Biosciences, Oxford, UK), and subsequently immunostained with rat anti-mouse GP2 monoclonal antibody (MAb; MBL International, Woburn, MA).
