Mathematical Modelling of Alternative Pathway of Complement System [PDF]

Bulletin of Mathematical Biology, 2020
Abstract The complement system (CS) is an integral part of innate immunity and can be activated via three different pathways. The alternative pathway (AP) has a central role in the function of the CS. The AP of complement system is implicated in several human disease pathologies.

Biochemical and functional studies of a novel complement inhibitor, CRIT, with its interaction partners [PDF]

, 2005
Complement C2 receptor trispanning (CRIT), a three transmembrane receptor, was first discovered on the surface of the parasite Schistosoma haematobium and formerly termed Schistosoma trispanning orphan receptor (Sh-TOR). This receptor acts as decoy C2-

Comparison of dominant and nondominant C3 deposition in primary glomerulonephritis [PDF]

Kidney Research and Clinical Practice, 2023
Background Alternative complement pathway dysregulation plays a key role in glomerulonephritis (GN) and is associated with C3 deposition. Herein, we examined pathological and clinical differences between cases of primary GN with C3-dominant (C3D-GN) and ...

Complement-coagulation cross-talk: a potential mediator of the physiological activation of complement by low pH

Frontiers in Immunology, 2015
The complement system is a major constituent of the innate immune system. It not only bridges innate and adaptive arms of the immune system but also links the immune system with the coagulation system.

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).

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

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 ...

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 ...

C2 by-pass: cross-talk between the complement classical and alternative pathways

, 2022
Several disorders associated with the total or partial absence of components of the human complement system are known. Deficiencies of classical pathway (CP) components are generally linked to systemic lupus erythematosus (SLE) or SLE-like syndromes ...
