Structural insights on complement activation [PDF]

open access: yesThe FEBS Journal, 2015
The proteolytic cleavage of C3 to generate C3b is the central and most important step in the activation of complement, a major component of innate immunity. The comparison of the crystal structures of C3 and C3b illustrates large conformational changes during the transition from C3 to C3b.

Early complementopathy predicts the outcomes of patients with trauma

open access: yesTrauma Surgery & Acute Care Open, 2019
Background Complementopathy (rapid complement activation and consumption after trauma) has been reported in trauma patients, but the underlying mechanism of these phenomena and their clinical significance remain unclear. This study aimed to determine the

Plasma samples from mouse strains and humans demonstrate different in vitro susceptibilities to complement activation

open access: yesPrecision Nanomedicine, 2018
Complement activation can be evaluated in vitro using plasma or serum from animals and human donors, and in vivo using animal models. Despite many years of research, there is no harmonized approach for the selection of matrix and animal models. Herein,

Complement Activation and Inhibition in Wound Healing

open access: yesClinical and Developmental Immunology, 2012
Complement activation is needed to restore tissue injury; however, inappropriate activation of complement, as seen in chronic wounds can cause cell death and enhance inflammation, thus contributing to further injury and impaired wound healing. Therefore,

Activation of human complement system by dextran-coated iron oxide nanoparticles is not affected by dextran/Fe ratio, hydroxyl modifications and crosslinking

open access: yesFrontiers in Immunology, 2016
While having tremendous potential as therapeutic and imaging tools, the clinical use of engineered nanoparticles has been associated with serious safety concerns. Activation of the complement cascade and release of proinflammatory factors C3a and C5a may

Impact of intrinsic localized modes of atomic motion on materials properties [PDF]

open access: yes, 2010
Recent neutron and x-ray scattering measurements show intrinsic localized modes (ILMs) in metallic uranium and ionic sodium iodide. Here, the role ILMs play in the behavior of these materials is examined.

FHR-1 binds to C-reactive protein and enhances rather than inhibits complement activation [PDF]

open access: yes, 2017
Factor H (FH)-related protein 1 (FHR-1) is one of the five human factor H-related proteins, which share sequence and structural homology with the alternative pathway complement inhibitor FH.

Terminal complement activation is increased and associated with disease severity in CIDP [PDF]

open access: yes, 2016
Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common chronic autoimmune neuropathy. While both cell-mediated and humoral mechanisms contribute to its pathogenesis, the rapid clinical response to plasmapheresis implicates a ...

Circulating histones as clinical biomarkers in critically ill conditions

open access: yesFEBS Letters, EarlyView.
Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.
