Alpha-synuclein activates the classical complement pathway and mediates complement-dependent cell toxicity [PDF]

Journal of Neuroinflammation, 2021
Background Synucleinopathies are characterized by neurodegeneration and deposition of the presynaptic protein α-synuclein in pathological protein inclusions.

A New Tool for Complement Research: In vitro Reconstituted Human Classical Complement Pathway [PDF]

Frontiers in Immunology, 2018
The complement, as part of the innate immune system, represents the first line of defense against Gram-negative bacteria invading the bloodstream. The complement system is a zymogen cascade that ultimately assemble into the so-called membrane attack ...

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 ...

Alternative Pathway Dysregulation and the Conundrum of Complement Activation by IgG4 Immune Complexes in Membranous Nephropathy [PDF]

, 2016
Membranous nephropathy (MN), a major cause of nephrotic syndrome, is a non-inflammatory immune kidney disease mediated by IgG antibodies that form glomerular subepithelial immune complexes.

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-

Complement activation and protein adsorption by carbon nanotubes [PDF]

, 2006
As a first step to validate the use of carbon nanotubes as novel vaccine or drug delivery devices, their interaction with a part of the human immune system, complement, has been explored.

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 ...

Complementary Roles of the Classical and Lectin Complement Pathways in the Defense against Aspergillus fumigatus

Frontiers in Immunology, 2016
Aspergillus fumigatus infections are associated with a high mortality rate for immunocompromised patients. The complement system is considered to be important in protection against this fungus, yet the course of activation is unclear.

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

Classical pathway complement activation on human endothelial cells [PDF]

Molecular Immunology, 2007
Endothelial cells regulate vascular integrity and express complement binding proteins including gC1qR/p33 (gC1qR), which recognize C1q, a subunit of the first component of the classical complement pathway. Experiments were performed to investigate classical complement pathway activation on resting endothelial cells and endothelial cells exposed to ...
