A Kinetic Model of Antigen‐Dependent IgG Oligomerization and Complement Binding

Small Science
The classical complement pathway (CCP) is an essential part of the immune system, activated when complement protein C1 binds to IgG antibody oligomers on the surface of pathogens, infected or malignant cells, culminating in the formation of the membrane ...

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Crosstalk between Complement and Toll-Like Receptors

, 2011
The complement system and toll-like receptors (TLRs) are two components of innate immunity that are critical for first-line host defense. Many pathogen-associated molecular patterns activate both complement and TLRs, and recent studies in animal models ...

The Differential Complement, Fc and Chemokine Receptor Expression of B Cells in IgG4-Related Pancreatobiliary Disease and Primary Sclerosing Cholangitis and Its Relevance for Targeting B Cell Pathways in Disease

Biomedicines
Background: Immune-mediated liver and biliary conditions, such as IgG4-related pancreatobiliary disease (IgG4-PB) and a subset of primary sclerosing cholangitis (PSC- high(h)IgG4), exhibit increased IgG4 levels in the blood.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

The role of complement in synaptic degeneration

, 2012
Synapse loss is an early event of many neurodegenerative diseases including Alzheimer?s disease and Parkinson?s disease. The causes and mechanisms that underpin synapse dysfunction and degeneration are poorly understood.

Biomimetic carbon nanopolymers ANM-NPs act on mannose receptors and complement receptors to promote tumor antigen presentation

Journal for ImmunoTherapy of Cancer
Background Enhancing immunogenicity and antigen-presentation efficiency is critical for tumor vaccine development. While yeast-surface glycoprotein side chains can improve antigen presentation, their ability to deliver tumor antigens remains limited ...

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Origin and diversification of steroids: Co-evolution of enzymes and nuclear receptors

, 2010
Recent sequencing of amphioxus and sea urchin genomes has provided important data for understanding the origins of enzymes that synthesize adrenal and sex steroids and the receptors that mediate physiological response to these vertebrate steroids ...

Donor specific transplant tolerance is dependent on complement receptors

, 2013
The complement system has recently been described as a crucial component for transplant tolerance induction, but the underlying mechanisms are poorly understood.
