Analysis of Transcriptomic Profile of Graft-versus-host Disease (GHVD) After Allogeneic Grafting...
Graft Vs Host DiseaseHematopoietic Stem CellsGraft-versus-host disease (GVHD) is a frequent and severe complication of hematopoietic stem cell transplantation (HSC), and is responsible for significant early mortality despite prophylactic strategies developed in recent decades, Especially since it is resistant to first-line treatment. The present diagnosis is difficult, non-specific and is based on the combination of an evocative clinical context (CSH allograft, time to appearance before J100, characteristic clinical manifestations), suggestive anatomo-pathological analysis (predominantly inflammatory infiltrate Lymphocyte, mucosal edema and presence of apoptotic bodies), and the exclusion of any differential diagnosis (in particular serology / negative viral PCR). However, to date there is no molecular characterization of this manifestation, and therefore no specific treatment. The nCounter® nanostring technology allows the rapid and simple analysis of the simultaneous expression of a group of genes (up to 800 on the same sample), from a very small amount of RNA, and from samples with difficulty Such as fabrics already fixed to formaldehyde and included in paraffin. It allows the detection of a "molecular signature" of the tissue analyzed. No transcriptomic analysis has ever been performed on human tissues with GVHD.
Developing a Functional Cure for HIV Disease: Clinical Specimen Collection From HIV Positive Individuals...
HIV InfectionsClinical specimens are required from HIV positive individuals with viremia controlled by antiretroviral therapy to complete process development for a genetically modified autologous T cell product, AGT103-T. The product will be used in a subsequent early stage clinical trial in subjects with chronic HIV disease and viremia suppressed by antiretroviral therapy as the initial step in testing a functional cure for HIV disease. Enrolled participants provide a venous blood specimen (approximately 25mL) to determine their level of HIV-reactive CD4+ T cells. Subjects with positive T cell responses will be asked to undergo leukapheresis and their clinical specimens will be used to validate and qualify the AGT103-T cell product.

Consequences of DNA Repair and Telomere Defects on the Function of the Immune System: Application...
Immune Deficiency and Early BMF in ChildhoodThe molecular mechanisms participating in the various aspects of the DNA Damage Response (DDR) are absolutely essential to maintain the genome dynamics essential to all living organisms. The most commonly studied consequence of faulty DDR is genome instability participating in cancer onset. In the present proposal, we wish to explore another aspect of DDR, not relevant to cancer, which is its absolute requirement at several key steps of the development, maturation, and function of the immune system. The most "spectacular" consequences of faulty DNA repair processes with respect to the immuno-hematopoietic tissue are the complete block of B and T lymphocytes maturation owing to defective DNA joining phase during V(D)J recombination resulting in patients with Severe Combined Immune Deficiency (SCID). The objectives of this study are to increase our knowledge on the role of the various DNA repair processes in the development, the maintenance, and the function of the immune system and thus, to better understand why and how dysfunctions of these DNA repair processes result in human severe conditions such as CVID, LOCID or other manifestations of immune disorders such as autoimmunity. The explorations of DNA repair mechanisms in the patients will allow us to establish the genetic diagnosis in some patients with until now undefined molecular diagnosis. This is of immediate importance for the patients and their families, as it not only contributes to a better understanding of the patients' condition, but also allows providing genetic counseling for the families.
