Absence of follicular localization of immune complexes in C1qA −/− mice. Spleens from wild-type (129/Sv × C57BL/6; n = 5) and strain-matched C1qA −/− (n = 5) mice were taken 24 h after intravenous injection with 500 μg FITC-labeled HAGG. FITC localization (green) was assessed in splenic sections relative to germinal centers (PNA expression; red) in wild-type (A) and C1qA −/− (B) mice. FDCs were detected by mAb FDC-M1 (red) in wild-type (C) and C1qA −/− (D) mice. Original magnification: 20 (A, B, and D) and 40 (C).
