System comprises four plasma proteins, circulating as zymogens in the bloodstream or being assembled on various cell types: the serine proteases factor XII (FXII), factor XI (FXI), and prekallikrein (PKK) and the nonenzymatic cofactor high-molecularweight kininogen (HK). The latter forms equimolar complexes with plasma kallikrein (PK) or FXI. The cascade is initiated upon contact to a negatively c

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

Phosphatase activity of PP2A in studies involving a second known binding partner of tAg, the JCV agnoprotein [40]. We were surprised to identify two LxCxE motifs that had been overlooked in the unique region of the JCV tAg; one of these sites is also found in BKV but neither site resides in the corresponding SV40, WUV, KIV or MCV polyomavirus proteins. As predicted, JCV tAg binds members of the re

Functions in order to finely control the immune response in vivo. Among its cellular functions, TNFa is able to induce cytokines, chemokines, proliferation, and also cell death. The induction of pro-inflammatory versus death signals depends upon the molecular context of the responding cell, and specifically whether NFjB is involved [8]. Adding to the complexity of signaling, it is also reported th
