Research Abstract |
We investigated whether a novel monocyte, or spontaneous plaque-forming cell (SPFC), is related with renal allograft rejection in man , and how SPFC generation may be regulated in vitro. A auto-rosette-forming T cell (ARFC-T) may act as helper cell of SPFC-monocyte, while non-ARFC-T and ARFC-monocyte may act as suppressor of SPFC generation. Other environmental antigens, such as influenza virus, cytomegalovirus and E.Coli lipopolyssacharide, and allo-PBMC of man can affect the SPFC generation. In vivo SPFC response can be reflected in the invading cells from rejected grafts, detected by the in vitro MLC-SPFC assay. A definite correlation between graft survival and in vitro SPFC response was observed, that is, an excellent renal allograft survival was shown in the non-response patients of SPFC. The present results suggest that a novel monocyte, SPFC, may relate to renal allograft rejection and that a further study of SPFC-monocyte will give a key to open a new immunosuppression.
