Cholesterol Crystals Activate the Lectin Complement Pathway via Ficolin-2 and Mannose-Binding Lectin: Implications for the Progression of Atherosclerosis. [PDF]

, 2016
Cholesterol crystals (CC) play an essential role in the formation of atherosclerotic plaques. CC activate the classical and the alternative complement pathways, but the role of the lectin pathway is unknown.

Activation of the alternative complement pathway by Histoplasma capsulatum [PDF]

Infection and Immunity, 1980
The present study was performed to determine whether Histoplasma capsulatum (yeast phase) is able to activate the alternative complement pathway. H. capsulatum yeasts were shown to consume C3 in C4-deficient guinea pig serum. Immunoelectrophoretic conversion of alternative pathway component factor B confirmed that C3 consumption was mediated by ...

Circulating histones as clinical biomarkers in critically ill conditions

FEBS Letters, EarlyView.
Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.

Therapeutic approaches with intravitreal injections in geographic atrophy secondary to age-related macular degeneration: current drugs and potential molecules [PDF]

, 2019
The present review focuses on recent clinical trials that analyze the efficacy of intravitreal therapeutic agents for the treatment of dry age-related macular degeneration (AMD), such as neuroprotective drugs, and complement inhibitors, also called ...

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

FEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Ecotin, a microbial inhibitor of serine proteases, blocks multiple complement dependent and independent microbicidal activities of human serum.

PLoS Pathogens, 2019
Ecotin is a serine protease inhibitor produced by hundreds of microbial species, including pathogens. Here we show, that ecotin orthologs from Escherichia coli, Yersinia pestis, Pseudomonas aeruginosa and Leishmania major are potent inhibitors of MASP-1 ...

FHR-1 binds to C-reactive protein and enhances rather than inhibits complement activation [PDF]

, 2017
Factor H (FH)-related protein 1 (FHR-1) is one of the five human factor H-related proteins, which share sequence and structural homology with the alternative pathway complement inhibitor FH.

Activation of the Alternative Complement Pathway by Fonsecaea pedrosoi

Journal of Investigative Dermatology, 1984
Human sera were examined for evidence of complement activation by Fonsecaea pedrosoi. The serum that had been incubated with F. pedrosoi showed immunoelectrophoretic C3 conversion and generation of C5a, as measured by radioimmunoassay. C3 conversion and C5a generation did not occur in serum chelated with EDTA, or in serum heated to 56 degrees C for 30 ...

Activation of the alternative complement pathway by Trichomonas vaginalis [PDF]

Infection and Immunity, 1981
The mechanism underlying the lysis of Trichomonas vaginalis by normal human or guinea pig serum was investigated. The involvement of the complement system was demonstrated by the failure of human serum deficient in C3 or C8 to mediate parasite killing and by the ablation of lytic activity observed when fresh sera were heated at 56 degrees C or treated ...
