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.

Paths reunited: initiation of the classical and lectin pathways of complement activation [PDF]

, 2010
Understanding the structural organisation and mode of action of the initiating complex of the classical pathway of complement activation (C1) has been a central goal in complement biology since its isolation almost 50 years ago.

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.

Borrelia valaisiana resist complement-mediated killing independently of the recruitment of immune regulators and inactivation of complement components [PDF]

, 2013
Spirochetes belonging to the Borrelia (B.) burgdorferi sensu lato complex differ in their resistance to complement-mediated killing, particularly in regard to human serum.

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 ...

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

A hierarchical role for classical pathway complement proteins in the clearance of apoptotic cells in vivo [PDF]

, 2000
The strongest susceptibility genes for the development of systemic lupus erythematosus (SLE) in humans are null mutants of classical pathway complement proteins. There is a hierarchy of disease susceptibility and severity according to the position of the

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 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).
