Figure S6.  Spleen. TRAF2, green; DAPI counterstain, blue. In situ immunofluorescence analysis of SOCS2 induction, TRAF2 and TRAF6 expression, and proinflammatory gene expression after proteasome inhibition during T. gondii infection of WT and SOCS2-deficient mice. Mice were infected intraperitoneally with 20 cysts of T. gondii (ME49 strain), and were treated with PBS or PR11 as indicated in Fig. S3. Representative photomicrographs from (63× magnification) frozen sections of brains or spleens are shown. CT, uninfected control; Tg, T. gondii-infected. Bars, 50 µm.
