Kawasaki disease is the most common cause of multisystem vasculitis in childhood. The resultant coronary artery lesions make Kawasaki disease the leading cause of acquired heart disease in children in the developed world. TNF-alpha is a pleiotropic inflammatory cytokine elevated during the acute phase of Kawasaki disease. In this study, we report rapid(More)
DNA damage response (DDR) is a signaling network that senses DNA damage and activates response pathways to coordinate cell-cycle progression and DNA repair. Thus, DDR is critical for maintenance of genome stability, and presents a powerful defense against tumorigenesis. Therefore, to drive cell-proliferation and transformation, viral and cellular oncogenes(More)
Belimumab (Benlysta(®)) is a fully humanized monoclonal antibody that inhibits B-lymphocyte stimulator (also known as B cell activating factor of the tumor necrosis factor family) and was approved by the US Food and Drug Administration and the European Medicines Evaluation Agency for treatment of autoantibody-positive systemic lupus erythematosus (SLE) in(More)
OBJECTIVE To evaluate the use and efficacy of belimumab in academic practices. Belimumab is a human monoclonal antibody that inhibits soluble B lymphocyte stimulator and has been approved for the treatment of adults with systemic lupus erythematosus (SLE). METHODS Invitations to participate and complete a 1-page questionnaire for each patient prescribed(More)
Infection of B cells with Epstein-Barr virus (EBV) leads to proliferation and subsequent immortalization, resulting in establishment of lymphoblastoid cell lines (LCL) in vitro. Since LCL are latently infected with EBV, they provide a model system to investigate EBV latency and virus-driven B cell proliferation and tumorigenesis(1). LCL have been used to(More)
The objective of the study was to compare clinical features, treatment and disease outcome in patients with early versus later onset of childhood-onset systemic lupus erythematosus (cSLE). A retrospective matched cohort study of cSLE patients diagnosed between 1988 and 2008 and followed for a minimum of one year was conducted. Thirty-four pre-pubertal cSLE(More)
Belimumab (Benlysta) is a fully-humanized monoclonal antibody that inhibits B-lymphocyte stimulator (also known as B cell activating factor) and was approved by the U.S. Federal Drug Administration and European Medicines Evaluation Agency for treatment in adults with autoantibody-positive systemic lupus erythematosus (SLE). Rituximab (Rituxan) is a chimeric(More)
Infection of primary B lymphocytes with Epstein-Barr virus gives rise to growth-transformed and immortalized lymphoblastoid cell lines (LCL) in vitro. Among their many applications is the use of LCL to present antigens in a variety of immunologic assays and to generate human monoclonal antibodies. This chapter describes a method to generate LCL from donor(More)
BACKGROUND Systemic lupus erythematosus (SLE) is a multi-system, complex disease in which the environment interacts with inherited genes to produce broad phenotypes with inter-individual variability. Of 46 single nucleotide polymorphisms (SNPs) shown to confer genetic risk for SLE in recent genome-wide association studies, 30 lie within noncoding regions of(More)
