MECHANISM OF GRAFT-VERSUS-HOST-INDUCED LYMPHADENOPATHY IN MICE

Abstract
Graft-vs.-host (GVH)-induced lymphadenopathy of the popliteal lymph node has been produced in C57BL/6 x A/J F1 (BAF1) mice by injecting A/J spleen cells into the rear footpads. By giving 51Cr-labeled BAF1 lymphoid cells intravenously to the hosts, 24 h before sacrifice, we have demonstrated that a large portion of the GVH-induced lymphadenopathy is due to the trapping of circuating lymphocytes in the challenged lymph nodes.
