Figure 5.

Injected granules traffic to the DLN and contain functional TNF. (A) Toluidine blue staining of DLN tissue sections from an MC-deficient KitW-sh/W-sh mouse injected with 9.0 × 103 isolated MC-derived particles. Bar, 50 µm. (B) Same area as in A showing only metachromatic staining. The location of the edge of the DLN is depicted by a dashed line. (C) Magnification from square in A. Bar, 10 µm. (D) LN hypertrophy 24 h after injection of 1.5 × 104 particles purified from WT or TNF−/− mice (n = 3 for each group; *, P < 0.005 for the comparison between the two groups; data analyzed by unpaired two-tailed Student’s t test; error bars indicate standard error of the mean). All panels show results that are representative of two independent experiments.
