Quantitative Modeling of the Alternative Pathway of the Complement System. [PDF]

PLoS ONE, 2016
The complement system is an integral part of innate immunity that detects and eliminates invading pathogens through a cascade of reactions. The destructive effects of the complement activation on host cells are inhibited through versatile regulators that

Thrombotic microangiopathy mediates poor prognosis among lupus nephritis via complement lectin and alternative pathway activation

Frontiers in Immunology, 2022
ObjectiveThe pathogenesis of thrombotic microangiopathy (TMA) in lupus nephritis (LN) remains complicated. This study aimed to detect the deposition of complement lectin pathway (LP) and alternative pathway (AP) components in renal tissues, then evaluate

The Alternative Pathway of Complement Activation in the Neonate [PDF]

Pediatric Research, 1975
C3PA (factor B) concentrations taken as an indication of alternate pathway development for neonates and adults were compared. The mean level for umbilical cord sera was 39 +/- 2%, with a range of 19.5-77.5%. The normal adult mean level was 74 +/- 4%, with a range of 43-108%. The difference between the two is highly significant (P less than 0.001).

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 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 ...

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 ...

Complement 1 Inhibitor Is a Regulator of the Alternative Complement Pathway [PDF]

The Journal of Experimental Medicine, 2001
We studied complement 1 inhibitor (C1-INH) as an inhibitor of the alternative complement pathway. C1-INH prevented lysis, induced by the alternative complement pathway, of paroxysmal nocturnal hemoglobinuria (PNH) erythrocytes in human serum. It inhibited the binding of both factors B and C3 to PNH and rabbit erythrocytes and blocked the ability of ...

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

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.

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

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.
