Deficiency of dedicator of cytokinesis 8 (DOCK8) is a newly described combined primary immunodeficiency disease. It was found to account for 15% of combined immune deficiency cases in the National Primary Immunodeficiency Disorders Registry in Kuwait, a country with high prevalence of consanguinity. We present the clinical, immunologic and molecular characteristics of 9 Kuwaiti patients with DOCK8 deficiency and discuss differences that distinguish DOCK8 deficiency from atopic dermatitis. Clinical immunologists in areas with high incidence of consanguinity should have a high index of suspicion of DOCK8 deficiency in children with recalcitrant eczema, recurrent non-cutaneous infections and lymphopenia. 相似文献

Common variable immunodeficiency (CVID) is the most prevalent human primary immunodeficiency requiring medical attention. Until recently, the only known genetic defect specific to CVID was the inducible costimulatory receptor (ICOS) deficiency, which accounts for less than 1% of the patients. Recently, mutations in the TNF receptor family member transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI), which mediates isotype switching in B cells, were found to be present in 10% to 20% of patients with CVID. Mutations in TACI were also found in relatives of patients with CVID who had IgA deficiency (IgAD), as well as in a patient with isolated IgAD. In the majority of patients described to date, only one TACI allele is mutated, showing an autosomal dominant transmission of the disease. B cells from individuals with TACI mutations did not produce IgG and IgA in response to the TACI ligand a proliferation-inducing ligand (APRIL), probably reflecting impaired isotype switching. These results suggest that TACI mutations can lead to CVID and IgAD. 相似文献

The binding site for TRAF2 and TRAF3 but not for TRAF6 is essential for CD40-mediated immunoglobulin class switching 总被引:11,自引:0,他引:11

To define the role of TRAF proteins in CD40-dependent isotype switching in B cells, we introduced wild-type (WT) and mutant CD40 transgenes that lacked the binding motifs for TRAF6 (CD40deltaTRAF6), TRAF2 and TRAF3 (CD40deltaTRAF2/3), or both (CD40deltaTRAFs) into B cells of CD40(-/-) mice. The in vivo isotype switch defect in CD40(-/-) mice was fully corrected by WT and CD40deltaTRAF6, partially by CD40deltaTRAF2/3, and not at all by CD40deltaTRAFs transgenes. CD40-mediated isotype switching, proliferation, and activation of p38, JNK, and NFkappaB in B cells were normal in WT and CD40deltaTRAF6 mice, severely impaired in CD40deltaTRAF2/3, and absent in CD40deltaTRAFs mice. These results suggest that binding to TRAF2 and/or TRAF3 but not TRAF6 is essential for CD40 isotype switching and activation in B cells. 相似文献
