In vitro Inhibition of Canine Complement‐Mediated Hemolysis
BACKGROUND Immune-mediated hemolytic anemia (IMHA) is the most common hematologic immune-mediated disease in dogs. Complement fixation on erythrocytes causes hemolysis. Complement inhibition decreases hemolysis in people with the hemolytic disease and also may prove effective in treating IMHA in dogs. HYPOTHESIS/OBJECTIVES Evaluate the in vitro efficacy of 2 complement inhibitors used in huma...
متن کاملThe IgG-specific endoglycosidase EndoS inhibits both cellular and complement-mediated autoimmune hemolysis.
EndoS from Streptococcus pyogenes is an immunomodulating enzyme that specifically hydrolyzes glycans from human immunoglobulin G and thereby affects antibody effector functions. Autoimmune hemolytic anemia is caused by antibody-mediated red blood cell (RBC) destruction and often resists treatment with corticosteroids that also cause frequent adverse effects. We show here that anti-RhD (anti-D) ...
متن کاملComplement-mediated hemolysis: The involvement of oxidative stress and the ameliorating effect of Fermented Papaya Preparation
Objectives We studied the involvement of serum-complement (C') and oxidative stress in the hemolytic anemias Paroxysmal Nocturnal Hemoglobinuria (PNH) and Auto-Immune Hemolytic Anemia (AIHA), and the effect of Fermented Papaya Preparation (FPP), an antioxidant-containing yeast fermentation product of Carica papaya Linn. Methodology Normal human red blood cells (RBC) treated with the sulphydryl ...
متن کاملCcpA-mediated repression of streptolysin S expression and virulence in the group A streptococcus.
CcpA is the global mediator of carbon catabolite repression (CCR) in gram-positive bacteria, and growing evidence from several pathogens, including the group A streptococcus (GAS), suggests that CcpA plays an important role in virulence gene regulation. In this study, a deletion of ccpA in an invasive M1 GAS strain was used to test the contribution of CcpA to pathogenesis in mice. Surprisingly,...
متن کاملmannose-binding lectin mediated complement pathway in autoimmune neurological disorders
multiple sclerosis (ms) is a complex, demyelinating disease of the central nervous system (cns) with variable phenotypic presentations, while guillain-barre syndrome (gbs) is the prototypic acute inflammatory disorder that affects the peripheral nervous system. myasthenia gravis (mg) is a t cell dependent and antibody mediated autoimmune disease. although it has been shown that complement plays...
