Effect of anticomplement agent K-76 COOH in hamster-to-rat and guinea pig- to-rat xenotransplantation [PDF]

, 1995
In normal rats, the xenobiotic K76 inhibited the C5 and probably the C2 and C3 steps of complement and effectively depressed classical complement pathway activity, alternative complement pathway activity, and the C3 complement component during and well ...

Plasma Proteomic Analysis Reveals the Potential Role of Lectin and Alternative Complement Pathways in IgA Vasculitis Pathogenesis

Diagnostics, 2023
Background: IgA vasculitis (IgAV) is the most common form of childhood vasculitis. A better understanding of its pathophysiology is required to identify new potential biomarkers and treatment targets.

Blood protein adsorption onto chitosan [PDF]

, 2002
Chitosan was recently indicated to enhance osteogenesis, improve wound healing but to activate the coagulation and the complement systems. In the present study approximately 10nm thick chitosan film were prepared on aminopropyltriethoxysilane (APTES ...

Complement-Mediated Kidney Diseases: Role of Alternative Pathway in Glomerular Inflammation

Kidney International Reports
Complement-mediated kidney diseases (CMKDs) comprise a diverse group of rare disorders characterized by the activation of the complement system, leading to glomerular inflammation, kidney injury, and in some cases, kidney failure.

Heme Interactions as Regulators of the Alternative Pathway Complement Responses and Implications for Heme-Associated Pathologies

Current Issues in Molecular Biology, 2023
Heme (Fe2+-protoporphyrin IX) is a pigment of life, and as a prosthetic group in several hemoproteins, it contributes to diverse critical cellular processes. While its intracellular levels are tightly regulated by networks of heme-binding proteins (HeBPs)

Properdin: initiation of alternative complement pathway. [PDF]

Proceedings of the National Academy of Sciences, 1975
Activation of the classical complement (C) system involves conversion of C1 to its active state with subsequent cleavage of C4 and -d C2 so as to form the classical C3 convertase, C42 (a bar indicates the activated form of a protein), which sequentially cleaves C3 and C5 to initiate the cytolytic event associated with the complete reaction.

Alternative Pathway Inhibition by Exogenous Factor H Fails to Attenuate Inflammation and Vascular Leakage in Experimental Pneumococcal Sepsis in Mice. [PDF]

PLoS ONE, 2016
Streptococcus pneumoniae is a common cause of sepsis. Effective complement activation is an important component of host defence against invading pathogens, whilst excessive complement activation has been associated with endothelial dysfunction and organ ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
