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

Legionella pneumophila lipopolysaccharide activates the classical complement pathway [PDF]
Infection and Immunity, 1992 Legionella pneumophila is a gram-negative bacterium capable of entering and growing in alveolar macrophages and monocytes. Complement and complement receptors are important in the uptake of L. pneumophila by human mononuclear phagocytes. The surface molecules of L. pneumophila that activate the complement system are unknown.

The classical pathway triggers pathogenic complement activation in membranous nephropathy
Nature Communications, 2023 It is generally thought that complement activation in human membranous nephropathy (MN) occurs predominantly via the lectin or alternative pathway. Here, the authors show that the classical pathway is the dominant form of complement activation in MN and ...

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 ...

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 ...
