Figure 8
Accumulation of ⁵¹Cr-labeled T cells and DCs at skin sites of ACD. Mice were sensitized and challenged with the hapten OXA. T cells and DCs were generated as described in Methods, labeled with ⁵¹Cr, and injected intravenously 24 hours after hapten challenge. Six hours later, ears and internal organs were harvested and ⁵¹Cr was counted. Data represent percentage of incorporated ⁵¹Cr in the ear in relation to the combined radioactivity uptake in lungs, liver, and spleen. *P < 0.01 for WT versus CD18^–/– T cells; P = not significant for all other groups.
