Interferon gamma improves long-term efficacy of allogeneic mesenchymal stem cell therapy after acute myocardial infarction

Interferon gamma improves long-term efficacy of allogeneic mesenchymal stem cell therapy after acute myocardial infarction |
Résumé : | Cardiac cell therapy using allogeneic mesenchymal stem cells (MSCs) loses efficacy on the long term, probably by immune rejection of the cells. Our working hypothesis is that pretreatment with IFN-g of allogeneic MSCs improve cardiac cell therapy. In a rat model of allogeneic MSCs injection in post myocardial infarction, we compare the effect of autologous or allogeneic MSCs, pretreated or not with IFN-g. Cardiac function was assessed by echocardiography, alloimmunization by blood tests and cardiac repair by histological study. Despite a humoral and cellular alloimmunization, allogeneic MSCs pretreated with IFN-g improve cardiac repair and cardiac function in the long-term, similarly to autologous MSCs. Our study shows a beneficial effect of IFN-g specific to the context of allogeneic cell therapy and suggests a favorable immune modulation induced by IFN-g as the mechanism of the effect. |
