Identification of defensin binding to C1 complement [PDF]
In human serum we found strong defensin binding to the complexes of activated C1 complement (C) and C1 inhibitor (C1i). Purified C1q, activated C1 tetramer ( 2 2) and C1i did not bind defensin. When ( 2 2) was dissociated by EDTA, only the activated C1s (Cs) bound defensin.

Borrelia burgdorferi BBK32 Inhibits the Classical Pathway by Blocking Activation of the C1 Complement Complex. [PDF]
Pathogens that traffic in blood, lymphatics, or interstitial fluids must adopt strategies to evade innate immune defenses, notably the complement system.

Acquired angioedema due to C1-inhibitor deficiency (C1–INH-AAE) is a rare disease that can be diagnosed via complement testing. It often accompanies lymphoproliferative underlying diseases.

Effects of weak anchoring on C1 and C2 chevron structures [PDF]
We present a theoretical study of the effect of weak anchoring on the transition between C1 and C2 chevron structures in smectic C liquid crystals. We employ a continuum theory which allows for variable cone, azimuthal and layer tilt angles.

Potential therapeutic benefit of C1-esterase inhibitor in neuromyelitis optica evaluated in vitro and in an experimental rat model. [PDF]
Neuromyelitis optica (NMO) is an autoimmune demyelinating disease of the central nervous system in which binding of anti-aquaporin-4 (AQP4) autoantibodies (NMO-IgG) to astrocytes causes complement-dependent cytotoxicity (CDC) and inflammation resulting ...

Structure of the C1 complex of complement [PDF]
In PNAS, Mortensen et al. (1) propose a model of the C1 complex of complement derived from small-angle X-ray scattering (SAXS) and electron microscopy (EM) analyses that contradicts previously published models and suggests an intermolecular activation process. This proposal is largely derived from a conjectural structure of C1r2C1s2, the catalytic unit

Human plasma-derived C1 esterase inhibitor concentrate has limited effect on house dust mite-induced allergic lung inflammation in mice. [PDF]
C1 esterase inhibitor (C1-INH) can inhibit multiple pathways (complement, contact-kinin, coagulation, and fibrinolysis) that are all implicated in the pathophysiology of asthma.

Structure of the C1r–C1s interaction of the C1 complex of complement activation [PDF]
Significance C1 is a large complex that triggers the destruction of invading pathogens via lysis or by stimulation of innate and adaptive immune processes. It is composed of C1q, a protein with a bouquet-like architecture, together with a tetramer assembled from two copies each of the serine proteases C1r and C1s, which activate when ...

C1 esterase inhibitor-mediated immunosuppression in COVID-19: Friend or foe?
From asymptomatic to severe, SARS-CoV-2, causative agent of COVID-19, elicits varying disease severities. Moreover, understanding innate and adaptive immune responses to SARS-CoV-2 is imperative since variants such as Omicron negatively impact adaptive ...

Structural Model for Factor X Inhibition of IgM and Complement-Mediated Neutralization of Adenovirus
Adenovirus has strong therapeutic potential as an oncolytic virus and gene therapy vector. However, injecting human species C serotype 5 adenovirus, HAdv-C5, into the bloodstream leads to numerous interactions with plasma proteins that affect viral ...
