Figure 4: Adoptive transfer of dendritic cells expressing FasL (FasLDCs) reduces colonic T cell and neutrophil infiltration. A. quantification of CD3+ cells per high-power field (HPF, 400x) of colonic tissue from rats treated with FasL-DCs or dendritic cells transfected with an empty vector (EV-DCs). Tissues were stained by immunohistochemistry for CD3. n=30 HPFs per group. B. Myeloperoxidase activity (IU/mg) in colonic tissue from EV-DCand FasL-DC-treated rats. n=2 per group. ** p<0.01 vs EV-DC group.
