Human complement factor H. Two factor H proteins are derived from alternatively spliced transcripts [PDF]

, 1991
The human complement factor H is an important component in the control of the alternative pathway of complement activation. We have previously shown that at least three factor H homologous mRNA species of 4.3 kb, 1.8 kb and 1.4 kb in length are ...

Alternative complement pathway deregulation is correlated with dengue severity. [PDF]

PLoS ONE, 2009
BACKGROUND:The complement system, a key component that links the innate and adaptive immune responses, has three pathways: the classical, lectin, and alternative pathways. In the present study, we have analyzed the levels of various complement components

The Alternative Complement Pathway Is Activated Without a Corresponding Terminal Pathway Activation in Patients With Heart Failure

Frontiers in Immunology, 2021
ObjectiveDysregulation of the complement system has been described in patients with heart failure (HF). However, data on the alternative pathway are scarce and it is unknown if levels of factor B (FB) and the C3 convertase C3bBbP are elevated in these ...

The Emerging Role of Complement Proteins as a Target for Therapy of IgA Nephropathy

Frontiers in Immunology, 2019
IgA nephropathy (IgAN) is the most common form of primary glomerulonephritis worldwide and a common cause of end-stage renal disease. Evaluation of a kidney biopsy is necessary for diagnosis, with routine immunofluorescence microscopy revealing dominant ...

Low molecular weight polysialic acid binds to properdin and reduces the activity of the alternative complement pathway

Scientific Reports, 2022
Sialic acids as the terminal caps of the cellular glycocalyx play an essential role in self-recognition and were shown to modulate complement processes via interaction between α2,3-linked sialic acids and complement factor H. Previously, it was suggested

Mannose binding lectin is required for alphavirus-induced arthritis/myositis [PDF]

, 2015
Mosquito-borne alphaviruses such as chikungunya virus and Ross River virus (RRV) are emerging pathogens capable of causing large-scale epidemics of virus-induced arthritis and myositis.

Contribution of complement activation pathways to neuropathology differs among mouse models of Alzheimer's disease [PDF]

, 2011
Background Complement proteins and activation products have been found associated with neuropathology in Alzheimer's disease (AD). Recently, a C5a receptor antagonist was shown to suppress neuropathology in two murine models of AD, Tg2576 and

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 ...
