Abstract: | Sensitized lymphocytes from mice immunized with skin homografts produce migration inhibitory factor upon incubation with lymphocytes (antigen) from the sensitizing strain. The MIF is produced within 14 hr following incubation of sensitized lymphocytes and antigen. In this reaction, antigenic specificity is a prerequisite for MIF production; however, the action of MIF transcends the strain barrier. Also, MIF produced in homograft reactions in mice inhibited the migration of peritoneal cells from normal guinea pigs. Finally, lymphocytes from mice bearing skin homografts do not develop the capacity to produce MIF prior to the rejection of the sensitizing skin grafts. |
