objective: due to the increased prevalence of thyroid dysfunction in subjects with type 2 diabetes and also this fact that antibodies could potentially identify subjects at risk of thyroid dysfunction, this study was conducted to investigate thyroid autoimmunity in type 2 diabetic patients. material and methods: among patients referred to yazd diabetes research center, 4000 type 2 diabetic pati...
Development of inhibitory antibodies to coagulation factor VIII (fVIII) is the primary obstacle to the treatment of hemophilia A in the developed world. This adverse reaction occurs in 20-30% of persons with severe hemophilia A treated with fVIII-replacement products and is characterized by the development of a humoral and neutralizing immune response to fVIII. Patients with inhibitory anti-fVI...
Approximately 25% of patients with hemophilia A develop inhibitory antibodies after treatment with factor VIII. Most of the inhibitory activity is directed against epitopes in the A2 and C2 domains. Anti-A2 inhibitory antibodies recognize a 25-residue segment bounded by R484-I508. Several antigenic residues in this segment have been identified, including R484, R489, and P492. The immunogenicity...
HIV-1 replication is markedly upregulated in alveolar macrophages (AM) during pulmonary tuberculosis (TB). This is associated with loss of an inhibitory CCAAT enhancer binding protein beta (C/EBPbeta) transcription factor and activation of nuclear factor (NF)-kappaB. Since the cellular immune response in pulmonary TB requires lymphocyte--macrophage interaction, a model system was developed in w...
Fifteen hybridomas secreting monoclonal antibodies against human antithrombin III, originating from two mouse strains, have been produced by the cell fusion technique. Eight monoclonal antibodies belong to the class IgG1, five to the class IgG2a, and two to the class IgG2b. All light chains belong to the kappa group. No cross-reaction of the monoclonal antibodies have been observed with a crude...
Coagulation factor XI (FXI) is a promising target for anticoagulation, because of its major role in thrombosis and relatively minor role in haemostasis. This implies that inhibition of FXI can prevent thrombosis without causing bleeding. It was our aim to investigate the antithrombotic properties of two novel inhibitory anti-human FXI antibodies (αFXI-175 and αFXI-203). The in vitro properties ...
Monoclonal antibodies are among the most promising therapeutic agents for treating cancer. Therapeutic cancer antibodies bind to tumor cells, turning them into targets for immune-mediated destruction. We show here that this antibody-mediated killing of tumor cells is limited by a mechanism involving the interaction between tumor cell-expressed CD47 and the inhibitory receptor signal regulatory ...
Stimulation with glucocorticoids of mouse splenic lymphocytes and peritoneal adherent cells resulted in the formation of a soluble factor--i.e., glycosylation inhibiting factor (GIF)--that inhibits the assembly of N-linked oligosaccharide(s) to IgE-binding factors during their biosynthesis. The major cell sources of GIF are Lyt 2+ I-J+ T cells and macrophages, respectively. The molecular size o...
