Low molecular weight polysialic acid binds to properdin and reduces the activity of the alternative complement pathway [PDF]

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

The Alternative Complement Pathway Is Activated Without a Corresponding Terminal Pathway Activation in Patients With Heart Failure [PDF]

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 ...

DYSFUNCTION OF COMPLEMENT SYSTEM IN FAMILIAL MEDITERRANEAN FEVER

Медицинская иммунология, 2014
. During attacks of familial mediterranean fever (FMF), multiple systemic events are triggered, most of which promote autoinflammatory reactions. A molecular pattern of immune abnormalities in FMF is yet unclear.

Looking back on the alternative complement pathway [PDF]

Immunobiology, 2018
The alternative pathway of complement originated from the Properdin pathway originally described by the Pillemer laboratory in the 1950s. This work generated great controversy and it took several decades for a consensus on its components, its reaction sequence and its functions to emerge.

PolySialic Acid Nanoparticles Actuate Complement-Factor-H-Mediated Inhibition of the Alternative Complement Pathway: A Safer Potential Therapy for Age-Related Macular Degeneration [PDF]

Pharmaceuticals
The alternative pathway of the complement system is implicated in the etiology of age-related macular degeneration (AMD). Complement depletion with pegcetacoplan and avacincaptad pegol are FDA-approved treatments for geographic atrophy in AMD that, while

Complement alternative pathway activation in human nonalcoholic steatohepatitis. [PDF]

PLoS ONE, 2014
The innate immune system plays a major role in the pathogenesis of nonalcoholic steatohepatitis (NASH). Recently we reported complement activation in human NASH.

Mutations in the alternative complement pathway in multiple myeloma patients with carfilzomib-induced thrombotic microangiopathy [PDF]

Blood Cancer Journal, 2023
Thrombotic microangiopathy (TMA) has been reported to occur in multiple myeloma (MM) patients in association with treatment with carfilzomib, an irreversible proteasome inhibitor (PI).

Properdin and Factor H: Opposing Players on the Alternative Complement Pathway “See-Saw” [PDF]

Frontiers in Immunology, 2013
Properdin and factor H are two key regulatory proteins having opposite functions in the alternative complement pathway. Properdin up-regulates the alternative pathway by stabilizing the C3bBb complex, whereas factor H downregulates the pathway by ...

Dengue virus and the complement alternative pathway [PDF]

FEBS Letters, 2020
Dengue disease is an inflammatory‐driven pathology, and complement overactivation is linked to disease severity and vascular leakage. Additionally, dysregulation of complement alternative pathway (AP) components has been described, such as upregulation of complement factor D and downregulation of complement factor H (FH), which activate and inhibit the

The alternative complement pathway is dysregulated in patients with chronic heart failure. [PDF]

Sci Rep, 2017
The complement system, an important arm of the innate immune system, is activated in heart failure (HF). We hypothesized that HF patients are characterized by an imbalance of alternative amplification loop components; including properdin and complement ...
