Depletion of αβ T cells or γδ T cells in the spleen and the ileum after anti-CD2 monoclonal antibody (mAb), anti-CD4 mAb, anti-αβ T cell receptor (TCR), or anti-γδ TCR treatment. Values are mean (SD) of absolute numbers per PALS/mm2 of spleen or absolute numbers/mm2 mucosa of the ileum
| mAb treatment | No αβ T cells in PALS/mm2 spleen | No γδ T cells in PALS/mm2 spleen | No αβ T cells/mm2 ileum | No γδ T cells/mm2 ileum |
