The result is a suppression of the primary IgM antibody production in vitro and in vivo. Clearly, regulatory antibodies play a key part in physiopathological situations. This applies experimentally to autoimmune reactions and allergies, e.g. to allergic encephalomyelitis, transplantation tolerance and ...
Fig. 1: Detection of AnxA1 in periprosthetic tissue and the identification of cells expressing AnxA1. aDetection of AnxA1 in synovial tissues from patients who were undergoing revision surgery by IHC staining with specific antibodies targeting AnxA1, CD68 macrophages and neutrophil elastase. Arrows ...
Plasmacytoid DCs also upregulate ICOS ligand upon maturation, which has been shown to drive differentiation of T cells into Tr1 cells[29]. TGF-β1 production by DCs drives Tr1 differentiation TGF-β may also have a role in priming Tr1 differentiation, since addition of neutralizing antibodies ...
The bacterial allergic reactions are distinguished by having fixed tissue antibodies. They have also been used as patterns for animal experimentation. Other experimental approaches involve the use of isoantibodies (cytotoxic antibodies) and autoantibodies. In the absence of other than morphologic criteria,...

Complement was discovered approximately 100 years ago as a heat-sensitive component of plasma that enhances the opsonization of bacteria by antibodies and facilitates antibody-dependent killing of bacteria.1 The original report assigned the name “complement” to this component to reflect the idea that...
of Human Actin Beta (ACTb) ELISA Kit (BMASSAY) based on the manufacturer’s recommendations. Furthermore, 100 μl of serum (ρprotein= 0.5 mg/ml) was added to pits coated with antibodies specific for the analyzed proteins and then incubated (1.5 hours, 37°C). Following incubation contents...
Autoimmune diseases affect 5–9% of the world’s population. It is now known that genetics play a relatively small part in the pathophysiology of autoimmune disorders in general, and that environmental factors have a greater role. In this review, we exam
Patients with primary ONFH exhibit lupus anticoagulants, anticardiolipin antibodies, the factor V Leiden mutation, the prothrombin gene G20210A mutation, the methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphism, and P1A1/A2 polymorphism in glycoprotein IIIa, along with decreased ...
Delayed skin reaction to tuberculin were elicited in 10 healthy persons by patch testing and intracutaneous application of the antigen (Tine-Test). Biopsies revealed basically identical tissue reactions. After intracutaneous injection of the antigen as well as after Tine-testing the changes were solely...
