Activation of human complement system by dextran-coated iron oxide nanoparticles is not affected by dextran/Fe ratio, hydroxyl modifications and crosslinking

Frontiers in Immunology, 2016
While having tremendous potential as therapeutic and imaging tools, the clinical use of engineered nanoparticles has been associated with serious safety concerns. Activation of the complement cascade and release of proinflammatory factors C3a and C5a may

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.

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

, 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.

Modern view on the complement system role in membranous nephropathy

Терапевтический архив, 2022
Membranous nephropathy (MN), an immune-mediated glomerular disease, is the most common cause of adult nephrotic syndrome. In MN, proteinuria is developed by podocyte damage due to the complement system activation in response to the subepithelial ...

Backbone dynamics of complement control protein (CCP) modules reveals mobility in binding surfaces [PDF]

, 2004
The regulators of complement activation (RCA) are critical to health and disease because their role is to ensure that a complement-mediated immune response to infection is proportionate and targeted.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Antimicrobial peptides and complement in neonatal hypoxia-ischemia induced brain damage [PDF]

, 2015
Hypoxic-ischemic encephalopathy (HIE) is a clinical condition in the neonate, resulting from oxygen deprivation around the time of birth. HIE affects 1-5/1000 live births worldwide and is associated with the development of neurological deficits ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

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

The Role of Complement in Cancer Immunotherapy [PDF]

, 2022
The dual role of complement in both cancer development and treatment has been investigated extensively and is characterized by a substantial literature that documents the conditions in which complement can either enhance tumor growth or promote the ...
