In this prospective study including 78 adult patients with haematological malignancy (90 episodes) we performed galactomannan (GM) (Platelia Aspergillus) screening twice weekly for the diagnosis of invasive aspergillosis. There were five proven and four probable invasive aspergillosis cases. The sensitivity, specificity and positive and negative predictive values were 100, 88, 47 and 100%, resp...
Previous work done in our laboratory, using mouse models, showed that soluble Fas ligand (sFasL) can efficiently delete donor anti-host T cells during their activation against irradiated host cells in MLCs. In the mouse models, this ex vivo sFasL treatment abrogated graft-vs-host disease (GVHD) while sparing donor T cells with antitumor reactivity. The present work was performed with human cell...
A major goal of the transplant field is to selectively tolerize only those donor T cells recognizing host alloantigen and mediating graft-vs-host disease (GVHD). Recently, we described an ex vivo approach in which the blockade of the CD40 ligand (CD40L):CD40 costimulatory pathway in bulk MLR cultures induces donor CD4+ T cells to become specifically tolerant to MHC class II-disparate alloantige...
Acute graft-versus-host disease (GVHD) remains a leading cause of morbidity and nonrelapse mortality after allogeneic hematopoietic cell transplantation. The clinical staging of GVHD varies greatly between transplant centers and is frequently not agreed on by independent reviewers. The lack of standardized approaches to handle common sources of discrepancy in GVHD grading likely contributes to ...
Invariant NK T (iNKT) cells have an invariant TCR-alpha chain and are activated in a CD1d-restricted manner. They are thought to regulate immune responses and play important roles in autoimmunity, allergy, infection, and tumor immunity. They also appear to influence immunity after hemopoietic stem cell transplantation. In this study, we examined the role of iNKT cells in graft-vs-host disease (...
In previous studies, we showed the possibility of expanding in vitro polyclonal CTL lines directed against patient leukemia cells using effector cells derived from both HLA-matched and HLA-mismatched hematopoietic stem cell donors. Some CTL lines, especially those derived from an HLA-disparate donor, displayed residual alloreactivity against patient nonmalignant cells. In this study, we evaluat...
