Clinical Trial Summary

NK cells are lymphocytes who play a role in the control of viral infections , tumor and fœtal tolerance. They belong to innate immune cells but they have a link with adaptative immunity. Indeed, after some viral infections such as CMV, Chikungunya, B hepatitis etc, a subset of NKG2C+ NK cells expands and can transfer, in murine models, a " memory " that can better control CMV infections. CMV reactivation is a major cause of morbidity and mortality after allogeneic hematopoietic ste cell transplantation in humans. The aim of this prospective study is to evaluate the role of NK cells, in particular NKG2C+ NK cells in the control of CMV but also Adenovirus after allo HSCT. Peripheral NK cells from 30 and 10 patients who reactivated respectively CMV and AdV are prospectively studied (extensive phenotyping and functional studies before and after administration of anti viral drugs) and compared with 30 allotransplanted patients who didn't reactivate CMV in a pair analysis, and 30 healthy donors serologically + for CMV.


Clinical Trial Description

For both groups: 28ml of peripheral blood samples are collected at different points. Group 1 : before and after anti viral treatment . Control group 2: one point after allo-HSCT; Control group 3: 1 point before transplant. Phenotypical study of NK cells: activating and inhibitory receptors, activation and differentiation's markers. Phenotypical studies of the ligands on infected cells. Genotypic study of KIR receptors (Kirotype); functional studies: polyfunctionality essay (flow cytometry): degranulation CD107a, IFNg, TNFa production). ;
