title: Lymphocyte homing in mice: lack of significant alteration when H-2 antigen expression is moderately modified.
abstract: The part played by MHC antigens on lymphocyte homing has been investigated by inducing modifications of their expression on lymphoid cells. A significant, though moderate, enhancement of H-2 antigen expression has been observed following in vitro treatment of lymphocytes with alpha-IFN. A decrease has been obtained after in vivo treatment of mice with chloramphenicol. These rather moderate alterations of H-2 density (ca. 20-30%, as determined by cytofluorometry) did not induced changes of lymphocyte capacity to home into the different lymphoid organs.
