| abstractText | In contrast to peripheral lymphoid organs, a high percentage of T cells in the liver are CD4+NKT cells. We asked whether adhesion molecules play any role in the accumulation of CD4+NKT cells in the liver. Liver CD4+NKT cells expressed ICAM-1 and high levels of LFA-1. In the livers of LFA-1-deficient mice, the number of CD4+NKT cells was markedly decreased. This reduction was restricted to the liver, and no reduction was found in the other organs analyzed. In contrast, the number of liver CD4+NKT cells in ICAM-1-deficient mice was only marginally reduced. In a reciprocal radiation thymocyte reconstitution system with LFA-1-deficient and wild-type mice, LFA-1 expressed on liver cells other than CD4+NKT cells was required for an accumulation of CD4+NKT cells in the liver. These results demonstrate a crucial role for LFA-1 in the accumulation of CD4+NKT cells in the liver. |
