Targeting the Initiator Protease of the Classical Pathway of Complement Using Fragment-Based Drug Discovery

Molecules, 2020
The initiating protease of the complement classical pathway, C1r, represents an upstream and pathway-specific intervention point for complement-related autoimmune and inflammatory diseases.

Circulating immune-complexes and complement activation through the classical pathway in myeloperoxidase-ANCA-associated glomerulonephritis

Renal Failure, 2022
Background Anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis (AAGN) is the fulminant glomerular diseases with poor renal prognosis. Activation of the complement system has recently been reported in the pathogenesis of AAGN, but it

Quantification of classical and non-classical crystallization pathways in calcite precipitation [PDF]

, 2022
Crystal precipitation from aqueous solution occurs through multiple pathways. Besides the classical ion-by-ion addition, non-classical crystallization mechanisms, such as multi-ion polymer and nano-particle attachment, could be of great significance under certain circumstances.

Peptide inhibitor of complement C1 (PIC1), a novel suppressor of classical pathway activation: mechanistic studies and clinical potential

Frontiers in Immunology, 2014
The classical pathway of complement plays multiple physiological roles including modulating immunological effectors initiated by adaptive immune responses as well as an essential homeostatic role in the clearance of damaged self-antigens.

Paths reunited: initiation of the classical and lectin pathways of complement activation [PDF]

, 2010
Understanding the structural organisation and mode of action of the initiating complex of the classical pathway of complement activation (C1) has been a central goal in complement biology since its isolation almost 50 years ago.

Alternative Complement Pathway Inhibition Abrogates Pneumococcal Opsonophagocytosis in Vaccine-Naïve, but Not in Vaccinated Individuals

Frontiers in Immunology, 2021
To assess the relative contribution of opsonisation by antibodies, classical and alternative complement pathways to pneumococcal phagocytosis, we analyzed killing of pneumococci by human blood leukocytes collected from vaccine-naïve and PCV13-vaccinated ...

Solvent reaction coordinate for an S$_N$2 reaction [PDF]

J. Chem. Phys. 153, 024103 (2020), 2020
We study the prototypical SN2 reaction Cl$^-$ + CH$_3$Cl $\to$ CH$_3$Cl + Cl$^-$ in water using quantum mechanics / molecular mechanics (QM/MM) computer simulations with transition path sampling and inertial likelihood maximization. We have identified a new solvent coordinate to complement the original atom-exchange coordinate used in the classic ...

SALO, a novel classical pathway complement inhibitor from saliva of the sand fly Lutzomyia longipalpis. [PDF]

, 2016
Blood-feeding insects inject potent salivary components including complement inhibitors into their host's skin to acquire a blood meal. Sand fly saliva was shown to inhibit the classical pathway of complement; however, the molecular identity of the ...

FUNCTIONAL ACTIVITY OF COMPLEMENT CLASSIC WAY ACTIVATION COMPONENTS AND ART1CULAS DAMAGE IN RHEUMATOID ARTRITIS

Научно-практическая ревматология, 2000
A relationship between X - ray joints changes and functional activity of classical pathway complement components in R4 was investigated. 31 patients with the moderate activity ofRA (ARA 1987) have been examined. Disease duration was 4,5lyear±3,84 (SD). X-

Functional Analysis of Two Divergent C4 Isotypes in the Classical and Lectin Pathways of Complement Activation in the Common Carp (Cyprinus carpio)

Journal of Marine Science and Engineering, 2023
In the evolution of the complement system, a major humoral innate immune factor, the existence of multiple isotypes of the complement components is considered as a key strategy to enhance innate immune defense. Complement C4 is also diversified in a wide
