Functional Role of the Noncatalytic Subunit of Complement C5 Convertase [PDF]

The Journal of Immunology, 2000
Abstract The C5 convertase is a serine protease that consists of two subunits: a catalytic subunit which is bound in a Mg2+-dependent complex to a noncatalytic subunit. To understand the functional role of the noncatalytic subunit, we have determined the C5-cleaving properties of the cobra venom factor-dependent C5 convertase (CVF,Bb)

Development and characterization of novel anti‐C5 monoclonal antibodies capable of inhibiting complement in multiple species [PDF]

, 2019
Over the last decade there has been an explosion in complement therapies; one third of the drugs in the clinic or in development target C5 protein. Eculizumab, a monoclonal antibody (mAb) that binds C5 and blocks its cleavage by the convertase, is the ...

Processing‐Induced Performance Limits of Platinum Resistance Temperature Detectors for Reliable Organ‐On‐A‐Chip Sensing

Advanced Materials Interfaces, EarlyView.
The thermal budget imposed during oxide passivation is revealed as a key design parameter for Pt resistance temperature detectors in Organ‐on‐a‐Chip platforms. By establishing a direct processing–microstructure–device performance relationship, this work transforms an unavoidable fabrication step into a strategy for reliable integrated temperature ...

Meningococcal Sepsis in Patient with Paroxysmal Nocturnal Hemoglobinuria during Pegcetacoplan Therapy

Emerging Infectious Diseases
Complement C5 inhibitors bring an increased risk for Neisseria infections. A novel complement C3 inhibitor, pegcetacoplan, was recently approved to treat paroxysmal nocturnal hemoglobinuria, a condition commonly treated with complement C5 inhibitors. We

Intravitreal Therapy Against the Complement Factor C5 Prevents Retinal Degeneration in an Experimental Autoimmune Glaucoma Model

Frontiers in Pharmacology, 2019
In glaucoma, studies revealed an involvement of the complement system. In an experimental autoimmune glaucoma model, immunization with an optic nerve homogenate antigen (ONA) led to retinal ganglion cell (RGC) loss, while intraocular pressure (IOP ...

Anti-GD1a antibodies activate complement and calpain to injure distal motor nodes of Ranvier in mice [PDF]

, 2010
The motor axonal variant of Guillain-Barré syndrome is associated with anti-GD1a immunoglobulin antibodies, which are believed to be the pathogenic factor. In previous studies we have demonstrated the motor terminal to be a vulnerable site.

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Thymosin Alpha‐1 Provides Direct Neuroprotection by Engaging the Orexin Receptor HCRTR1 to Suppress Neuronal Necroptosis

Advanced Science, EarlyView.
In this study, we unveil a thymus‐brain endocrine axis wherein Tα1 engages HCRTR1 to inhibit RIPK3‐mediated necroptosis. This study nominates the Tal‐HCRTR1‐RIPK3 axis as a potent and clinically translatable therapeutic target for stroke and neurodegeneration.
