The lectin pathway of complement activation is a critical component of the innate immune response to pneumococcal infection. [PDF]

PLoS Pathogens, 2012
The complement system plays a key role in host defense against pneumococcal infection. Three different pathways, the classical, alternative and lectin pathways, mediate complement activation.

Complement alternative pathway activation in human nonalcoholic steatohepatitis. [PDF]

PLoS ONE, 2014
The innate immune system plays a major role in the pathogenesis of nonalcoholic steatohepatitis (NASH). Recently we reported complement activation in human NASH.

Alternative Complement Pathway in Carotid Atherosclerosis: Low Plasma Properdin Levels Associate With Long‐Term Cardiovascular Mortality [PDF]

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Complement activation may promote atherosclerosis. Yet, data on the to which extent complement, and more specifically the alternative complement pathway, is activated in patients with carotid atherosclerosis and related to adverse outcome in ...

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

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.

Deficient Alternative Complement Pathway Activity in Newborn Sera [PDF]

Pediatric Research, 1979
Neonatal susceptibility to overwhelming bacterial infection is commonly attributed to a relative deficiency in serum opsonic activity. However, few studies have compared the functional capacity of the classical complement pathway with that of the alternative complement pathway in the neonate.

Modeling the activation of the alternative complement pathway and its effects on hemolysis in health and disease. [PDF]

PLoS Computational Biology, 2020
The complement system is a powerful mechanism of innate immunity poised to eliminate foreign cells and pathogens. It is an intricate network of >35 proteins, which, once activated, leads to the tagging of the surface to be eliminated, produces potent ...

Preanalytical classical and alternative complement pathway activity loss. [PDF]

Biochem Med (Zagreb), 2019
Introduction: Complement functional analyses provide insight into the integrity of the entire complement reaction cascade. These tests are suitable for investigating suspected complement deficiencies. Falsely reduced test outcomes may result from preanalytical instabilities of individual complement components.

Crystal structure of a tripartite complex between C3dg, C-terminal domains of factor H and OspE of Borrelia burgdorferi [PDF]

, 2017
Complement is an important part of innate immunity. The alternative pathway of complement is activated when the main opsonin, C3b coats non-protected surfaces leading to opsonisation, phagocytosis and cell lysis.
