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 ...

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

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.

Staphylococcus aureus proteins Sbi and Efb recruit human plasmin to degrade complement C3 and C3b

, 2012
Upon host infection, the human pathogenic microbe Staphylococcus aureus (S. aureus) immediately faces innate immune reactions such as the activated complement system. Here, a novel innate immune evasion strategy of S. aureus is described.

C3 glomerulopathy: a kidney disease mediated by alternative pathway deregulation

Frontiers in Nephrology
C3 glomerulopathy (C3G) is an ultra-rare complement-mediated kidney disease caused by to the deregulation of the alternative pathway (AP) of proximal complement.

Inhibiting the alternative pathway of complement by reducing systemic complement factor B: Randomized, double-blind, placebo-controlled phase 1 studies with Sefaxersen

Immunobiology
An over-active alternative complement pathway has been implicated in the pathophysiology of multiple diseases, including IgA nephropathy and geographic atrophy secondary to age related macular degeneration.

Extracts of wheat gluten activate complement via the alternative pathway

, 1993
SUMMARY We studied the ability of wheat gluten and its subfractions to activate complement directly. A sensitive sandwich ELISA employing a monoclonal antibody (MoAb) to a C9 neoepitope exposed in the terminal complement complex (TCC), a ...
