Determination of Factors Involved in the Regulation of Immune Responses After Allogeneic Hematopoietic Stem Cell Transplantation
Trial Parameters
Brief Summary
The study concerns donors and patients receiving allogeneic stem cell haematopoietic transplantation. The aim of the study is to analyse HSC graft content in immune effector T (naive, memory, activated, exhausted) and immunoregulatory cell subtypes (Tregs, iNKT, MDSC) and correlate the results with post-transplant immune reconstitution of those different cell subtypes and clinical events (graft-versus-host-disease, relapse, infections). An ancillary study will focus on the impact of microbiota dysbiosis on post-transplant immune response and regulatory cell subsets.
Eligibility Criteria
Inclusion Criteria: * patient of the Nancy CHRU, for whom a CSH allograft is planned. or * hematopoietic stem cell donors received at Nancy's CHRU for the duration of the research Exclusion Criteria: * Positive HIV * active hepatitis B or C infection
