Fig. 4From: Fn14-Fc suppresses germinal center formation and pathogenic B cells in a lupus mouse model via inhibition of the TWEAK/Fn14 PathwayFn14-Fc reduced Tfh cell populations. Fn14-Fc or control-Fc-treated mice were sacrificed 21 days after the first injection. Spleens from mice in each group (n = 5/group) were examined by immunofluorescence staining with monoclonal Abs against CD4 (white), B220 (blue), GL-7 (green), and PD-1 (red).
