Autosomal recessive deficiencies of DNMT3B or ZBTB24 account for two-thirds of cases of immunodeficiency, centromeric instability and facial dysmorphism (ICF syndrome). This primary immunodeficiency (PID) is characterized mainly by an antibody deficiency, facial abnormalities and centromeric instability. We analyzed the national cohort of patients with ICF(More)
BACKGROUND Immunodeficiency Centromeric Instability and Facial anomalies (ICF) is a rare autosomal recessive disease characterized by reduction in serum immunoglobulins with severe recurrent infections, facial dysmorphism, and more variable symptoms including mental retardation. ICF is directly related to a genomic methylation defect that mainly affects(More)
FOXP3+ regulatory T cell (Treg) based cellular therapies represent promising therapeutic options in autoimmunity, allergy, transplantation and prevention of Graft Versus Host (GVH) Disease. Among human FOXP3-expressing CD4+T cells, only the CD45RA+ naïve Treg (nTreg) subset is suitable for in vitro expansion. However, FoxP3 expression decays in cells using(More)
We checked analytical performances of Optilite® analyser for immunoglobulins G, A, M, subclasses of IgG, free light chains of Ig (Freelite®) and complement's fractions using Binding Site reagents. CVs for repeteability and reproducibility showed very good results, respectively <3% and <10% for all tested parameters, in agreement with Ricos and SFBC(More)
Klhl6 belongs to the KLHL gene family, which is composed of an N-terminal BTB-POZ domain and four to six Kelch motifs in tandem. Several of these proteins function as adaptors of the Cullin3 E3 ubiquitin ligase complex. In this article, we report that Klhl6 deficiency induces, as previously described, a 2-fold reduction in mature B cells. However, we find(More)
Antibacterial antibody responses that target surfaces of live bacteria or secreted toxins are likely to be relevant in controlling bacterial pathogenesis. The ability to specifically quantify bacterial-surface-binding antibodies is therefore highly attractive as a quantitative correlate of immune protection. Here, binding of antibodies from various body(More)
Peripheral B-lymphocytes undergo a series of changes during the first few years of life. Encounters with foreign antigens lead to maturation and differentiation. Several primary antibody deficiencies (PADs) affecting B-cell development are associated with abnormalities in the composition and/or differentiation of B-cell compartments. The most recent(More)
