| Abstract: | B-cell reactivity, as expressed in a plasma cell reaction may be part of a graft-versus-host or host-versus-graft reaction. Cell transfer experiments were able to prove this. Histological evidence is presented for the occurrence of the so-called "allogeneic effect" during a graft-versus-host or host-versus-graft reaction in the rabbit spleen. Cell suspensions containing both T- and B-cells give rise to a cellular and a humoral immunity reaction component upon transfer to histoincompatible recipients. This can also occur during a graft-versus-host reaction. This B-cell response is T-cell dependent. |
