Backbone dynamics of complement control protein (CCP) modules reveals mobility in binding surfaces [PDF]

, 2004
The regulators of complement activation (RCA) are critical to health and disease because their role is to ensure that a complement-mediated immune response to infection is proportionate and targeted.

Small-molecule factor D inhibitors selectively block the alternative pathway of complement in paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome

Haematologica, 2017
Paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome are diseases of excess activation of the alternative pathway of complement that are treated with eculizumab, a humanized monoclonal antibody against the terminal complement ...

Staphylococcus aureus proteins Sbi and Efb recruit human plasmin to degrade complement C3 and C3b [PDF]

, 2012
Upon host infection, the human pathogenic microbe Staphylococcus aureus (S. aureus) immediately faces innate immune reactions such as the activated complement system. Here, a novel innate immune evasion strategy of S. aureus is described.

Thromboinflammation Supports Complement Activation in Cancer Patients With COVID-19

Frontiers in Immunology, 2021
BackgroundCOVID-19 pathology is associated with exuberant inflammation, vascular damage, and activation of coagulation. In addition, complement activation has been described and is linked to disease pathology.

Mechanism of action of factor D of the alternative complement pathway. [PDF]

The Journal of experimental medicine, 1978
Factor D (C3 proactivator convertase) of human serum has been shown to be absolutely necessary for alternative pathway function, for activation of the C3/C5 convertase of that pathway and not to be a subunit of this enzyme. Factor D was found to be present in human plasma in active form only, at a concentration of 2 microgram/ml, and not to be ...

Engineering novel complement activity into a pulmonary surfactant protein [PDF]

, 2010
Complement neutralizes invading pathogens, stimulates inflammatory and adaptive immune responses, and targets non- or altered-self structures for clearance.

Potency measurements of the complement system facilitated by antibodies targeting the zymogen form of complement factor D (Adipsin) [PDF]

, 2022
The serine protease complement factor D is fundamental in the activation of the complement system. In addition, it was the first adipokine described (named Adipsin) and shown to improve beta cell function in diabetes.

Synovial Complement Factors in Patients with Periprosthetic Joint Infection after Undergoing Revision Arthroplasty of the Hip or Knee Joint

Diagnostics, 2021
The role and diagnostic value of the synovial complement system in patients with low-grade periprosthetic joint infection (PJI) are unclear. We sought to evaluate, for the first time, the usefulness of synovial complement factors in these patients by ...

CLONING OF THE 1.4-kb mRNA SPECIES OF HUMAN COMPLEMENT FACTOR H REVEALS A NOVEL MEMBER OF THE SHORT CONSENSUS REPEAT FAMILY RELATED TO THE CARBOXY TERMINAL OF THE CLASSICAL 150-kDa MOLECULE [PDF]

, 1991
Three factor H mRNA species of 4.3 kb, 1.8 kb, and 1.4 kb are constitutively expressed in human liver. Having previously characterized full-length cDNA clones derived from the 4.3-kb and 1.8-kb factor mRNA, we report here the isolation and eucaryotic ...

Estimation of interdomain flexibility of N-terminus of factor H using residual dipolar couplings [PDF]

, 2011
Characterization of segmental flexibility is needed to understand the biological mechanisms of the very large category of functionally diverse proteins, exemplified by the regulators of complement activation, that consist of numerous compact modules or ...
