Epitope specificity and isotype of monoclonal anti-D antibodies dictate their ability to inhibit phagocytosis of opsonized platelets
Rh immune globulin (WinRho SDF; Cangene, Mississauga, ON, Canada) is an effective treatment for autoimmune thrombocytopenic purpura; however, maintaining a sustained supply for its use in autoimmune thrombocytopenic purpura and its primary indication, hemolytic disease of the newborn, makes the development of alternative reagents desirable. We compared Rh immune globulin and 6 human monoclonal ant

Intravenous immunoglobulin inhibits anti-glycoprotein IIb-induced platelet apoptosis in a murine model of immune thrombocytopenia
We have previously shown that injection of anti-glycoprotein (GP) IIb induces murine immune thrombocytopenia (ITP) and that intravenous immunoglobulin (IVIg) ameliorates ITP. We hypothesise that murine ITP may be associated with platelet apoptosis, which is upregulated by anti-GPIIb and downregulated by IVIg. The current study demonstrated that anti-GPIIb injection induced three critical apoptosis
Quality of thrombin produced from the patient's own plasma using the TPD, a new Thrombin-processing Device
Thrombin derived from bovine sources commonly is used to arrest bleeding during surgical procedures. However, complications such as postoperative hemorrhage can occur because of the development of cross-reactive anti-bovine antibodies that inhibit human coagulation factor V. It would thus be advantageous to develop techniques to generate human thrombin. This study evaluated thrombin produced from
Does hormonal therapy improve sperm retrieval rates in men with non-obstructive azoospermia : a systematic review and meta-analysis
BACKGROUND: The beneficial effects of hormonal therapy in stimulating spermatogenesis in patients with non-obstructive azoospermia (NOA) and either normal gonadotrophins or hypergonadotropic hypogonadism prior to surgical sperm retrieval (SSR) is controversial. Although the European Association of Urology guidelines state that hormone stimulation is not recommended in routine clinical practice, a

Pathogenic T-cell responses in patients with autoimmune thrombocytopenic purpura
Autoimmune thrombocytopenic purpura (AITP) is a bleeding disorder in which autoantibodies are directed against an individual's own platelets, leading to enhanced clearance through Fc receptor (R)-mediated phagocytosis by macrophages residing in the reticuloendothelial system, particularly in the spleen. This review surveys the recent current literature and updates our understanding of the cell-med

T cell and cytokine abnormalities in patients with autoimmune thrombocytopenic purpura
Autoimmune thrombocytopenic purpura (AITP) is a bleeding disorder in which autoantibodies are directed against an individual's own platelets, leading to enhanced clearance through Fc receptor (R)-mediated phagocytosis by macrophages residing in the reticuloendothelial system, particularly in the spleen. Although the immunopathogenesis of the disease is autoantibody-mediated, there is now substanti
Immune pathophysiology of autoimmune thrombocytopenic purpura
Chronic autoimmune thrombocytopenic purpura (AITP) is an immune-mediated, bleeding disorder in which platelets are opsonized by autoantibodies and prematurely destroyed by phagocytic cells in the reticuloendothelial system. It is classed as an organ-specific autoimmune disease primarily mediated by immunoglobulin G (IgG) autoantibodies and its etiology appears to be similar to that observed for ot
Comparison of treatment retention of originator vs biosimilar products in clinical rheumatology practice in Sweden
OBJECTIVES: To compare treatment retention between biosimilars and their originator products among first starters (etanercept, infliximab, adalimumab and rituximab), as well as after non-medical switch. METHODS: Patients with rheumatic diseases starting, for the first time, an originator or biosimilar etanercept, infliximab, adalimumab or rituximab were identified in the national Swedish Rheumatol
Comparison of platelet immunity in patients with SLE and with ITP
Idiopathic thrombocytopenic purpura (ITP) is characterized by the development of a specific anti-platelet autoantibody immune response mediating the development of thrombocytopenia. Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by the production of a wide variety of autoantibodies. In 15-20% of SLE cases, patients develop thrombocytopenia which appears to be autoimmune
Intravenous immunoglobulin and anti-D in idiopathic thrombocytopenic purpura (ITP) : mechanisms of action
Infusion of large amounts of intravenous immunoglobulin (IVIG) or anti-D can reverse the low platelet count in patients with ITP within hours of the initiation of treatment. In some cases, the effects of IVIG appear to far outlast several half-lives of the product. Several mechanisms have been proposed to explain these rapid and long term effects and these will be discussed in this review.
Immunobiology of T helper cells and antigen-presenting cells in autoimmune thrombocytopenic purpura (ITP)
Autoimmune thrombocytopenic purpura (AITP) is a bleeding disease in which autoantibodies are directed against the individual's own platelets, resulting in enhanced Fc-mediated platelet destruction by macrophages in the reticuloendothelial system. Most research in AITP has focused on characterization of the autoantibodies, while little has been devoted to the cellular immune mechanisms leading to a

Cellular immune mechanisms in chronic autoimmune thrombocytopenic purpura (ATP)
Chronic autoimmune thrombocytopenic purpura (ATP) is a common autoimmune-mediated bleeding disease in which autoantibodies are directed against platelets, resulting in their enhanced Fc-mediated destruction by macrophages in the spleen. While there has been extensive studies relating to the autoantibodies in this autoimmune disorder, relatively few have dealt with cell-mediated immunoregulation of

Defensive shimmering responses in Apis dorsata are triggered by dark stimuli moving against a bright background
Giant honeybees, including the open-nesting Asian giant honeybee Apis dorsata, display a spectacular collective defence behaviour - known as 'shimmering' - against predators, which is characterised by travelling waves generated by individual bees flipping their abdomens in a coordinated and sequential manner across the bee curtain. We examined whether shimmering is visually mediated by presenting
