Acute SIV infection induces a dominant IgG/M over IgA response in GC. (A) Duodenal sections from controls (Ctl left panels) and macaques infected for 28 days (28 dpi, right panels) were stained with IRF4 mAb, IgA, IgG and IgM polyclonal Ab. Staining of one representative section for each group of macaques is shown. Magnification x200 and x1000 for enlarged images. (B-C) Each symbol represents the mean number of IgA, IgG and IgM plasma cells per GC in duodenum (B) and terminal ileum (C) in one macaque. Bars represent median values for each group.
