Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Immunogenicity of ALXN1820 (Tarperprumig) in Healthy Adults: Results of a Phase I Study. [PDF]
ABSTRACT Properdin is an endogenous positive regulator of the complement alternative pathway (AP). Tarperprumig (ALXN1820), a novel humanized bispecific antibody, binds properdin and albumin and is being developed to treat complement‐mediated diseases.

Regulation of the terminal complement cascade in adipose tissue for control of its volume, cellularity, and fibrosis. [PDF]
Abstract White adipose tissue (WAT) is a reservoir for various pathogens and their products, such as lipopolysaccharides. Therefore, it must be equipped with a defense mechanism connected with the activation of innate immunity. This explains the phenomenon that adipocytes express components of the classical and alternative complement pathways, which ...

CSF proteomics reveals changes in myelin and synaptic biology after Spectris treatment. [PDF]
Abstract INTRODUCTION Brain steady‐state gamma oscillations evoked using a non‐invasive medical device (Spectris) have shown potential clinical benefits in patients with mild–moderate Alzheimer's disease (AD), including reduced functional and cognitive decline, reduced brain volume and myelin loss, and increased brain functional connectivity.

Properdin Pattern Recognition on Proximal Tubular Cells Is Heparan Sulfate/Syndecan-1 but Not C3b Dependent and Can Be Blocked by Tick Protein Salp20 [PDF]
Introduction: Proteinuria contributes to progression of renal damage, partly by complement activation on proximal tubular epithelial cells. By pattern recognition, properdin has shown to bind to heparan sulfate proteoglycans on tubular epithelium and can

Initial properdin binding contributes to alternative pathway activation at the surface of viable and necrotic cells [PDF]
Properdin, the only known positive regulator of the complement system, stabilizes the C3 convertase, thereby increasing its half-life. In contrast to most other complement factors, properdin is mainly produced extrahepatically by myeloid cells.

Studies on relationship between serum properdin and cancer III. Influence of anticancer agents on the serum properdin level [PDF]
1. When the various anticancer agents are injected intravenously to normal rabbits and intraperitoneally to normal mice, it seems that the serum properdin levels fall transitorily for some hours after administration with a small dose and then keep rising,

Studies on relationship between serum properdin and cancer II. Studies on the serum properdin levels of tumor bearing animals and patients with malignant tumors [PDF]
1. The properdin levels in sera from mice bearing Ehrlich ascitic carcinoma and from rabbits with Brown-Pearce carcinoma decrease inversely with the increase of the ascites or the tumors. In the incipient period of tumor transplantation, the level rather
