Fig. 1From: BATF regulates collagen-induced arthritis by regulating T helper cell differentiationUpregulation of BATF in arthritic synovial tissues. a Representative images (n = 10) of BATF immunostaining in synovial tissue sections of nonimmunized (NI) and collagen-induced arthritis (CIA) wild-type (WT) DBA/1 J mice and Batf−/− littermates (knockout (KO)). b Representative immunostaining images (n = 8) of tumor necrosis factor (TNF)-α and interleukin (IL)-6 in CIA synovial tissues determined by immunohistochemical staining and immunofluorescence microscopy, respectively. c Representative triple-immunofluorescence microscopic images of mouse CIA synovial sections (n = 12) immunostained for BATF, cell type-specific markers, and DAPI.
