Streptococcal plasminogen activator, triggers the activation of the human contact system. Activation of contact system factors at the surface of the Streptococcus pyogenes serotype M49 is dependent on streptokinase and plasminogen. Our results also show that secreted streptokinase is an efficient contact system activator, independent from a contact surface. This results in the processing of high-m

Ons trigger an activation of the contact system more potently than strains isolated from noninvasive infections. The present study gives new insights into the mechanisms by which S. pyogenes triggers the human contact system and stresses the function of soluble and surface located plasmin exploited as a group A streptococcal virulence factor through the action of streptokinase. treptococcus pyogen

To mediate ADCC in vitro [9, 17, 23]. Although the contribution of ADCC activity to clinical efficacy is unclear, it is important to characterize all activities of the candidate mAb, especially those that can be affected by differences in post-translational modifications, such as glycosylation. The ability of ABP 501 to induce ADCC was assessed using MT-3 cells as target cells, and NK-92M1 cells s
