Functional and Structural Characterization of a Potent C1q Inhibitor Targeting the Classical Pathway of the Complement System

Frontiers in Immunology, 2020
The classical pathway of complement is important for protection against pathogens and in maintaining tissue homeostasis, but excessive or aberrant activation is directly linked to numerous pathologies.

Anti-SARS-Cov-2 S-RBD IgG Formed after BNT162b2 Vaccination Can Bind C1q and Activate Complement

Journal of Immunology Research, 2022
Background. The ability of vaccine-induced antibodies to bind C1q could affect pathogen neutralization. In this study, we investigated C1q binding and subsequent complement activation by anti-spike (S) protein receptor-binding domain (RBD) specific ...

Complement C3 mediates adolescent social isolation‐induced hippocampal synaptic deficits and sex‐specific emotional dysfunction

Interdisciplinary Medicine, EarlyView.
Adolescent social isolation disrupts hippocampal function and exacerbates emotional symptoms, with sex‐specific patterns, as shown by human studies. In mice, social isolation decreased hippocampal synaptic density and calcium signaling, upregulated complement proteins, and activated complement‐mediated microglial synaptic phagocytosis.

Increased complement C1q level marks active disease in human tuberculosis. [PDF]

PLoS ONE, 2014
BackgroundComplement functions as an important host defense system and complement C5 and C7 have been implicated in immunopathology of tuberculosis. However, little is known about the role of other complement components in tuberculosis.MethodsComplement ...

Analysis of the Recovery of Immune Status in the Patients With Paroxysmal Nocturnal Hemoglobinuria After Treatment With C5 Complement Inhibitor

Journal of Clinical Laboratory Analysis, EarlyView.
We retrospectively evaluated the impact of C5 complement inhibition on immune cell profiles and recovery in 27 PNH patients; both CD4+ and CD8+ T cells exhibited partial recovery, while B cell counts increased but remained below normal levels. In contrast, Treg cells were significantly reduced in PNH patients and showed no notable change post‐treatment.

Subretinal macrophages produce classical complement activator C1q leading to the progression of focal retinal degeneration

Molecular Neurodegeneration, 2018
Background The role of the alternative complement pathway and its mediation by retinal microglia and macrophages, is well-established in the pathogenesis of Age-Related Macular Degeneration (AMD).

Genome-wide gene expression profiling of stress response in a spinal cord clip compression injury model. [PDF]

, 2013
BackgroundThe aneurysm clip impact-compression model of spinal cord injury (SCI) is a standard injury model in animals that closely mimics the primary mechanism of most human injuries: acute impact and persisting compression.

An Open‐Label Phase 1b Study of the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Activity of ANX005 in Patients with Huntington's Disease

Movement Disorders, EarlyView.
Complement activation is implicated in Huntington's disease; ANX005 is a potent inhibitor of component C1q. ANX005 exhibited a generally manageable safety profile with rapid reduction in C1q in the cerebrospinal fluid. Functional ability on composite Unified Huntington's Disease Rating Scale and total functional capacity was maintained, with potential ...

Current Status of Kidney Xenotransplantation in Basic Research

Organ Medicine, EarlyView.
Kidney xenotransplantation is a potential solution to the organ shortage for end‐stage kidney disease. This review systematically elaborates on the application advances of donor pig gene editing technologies, the molecular mechanisms and regulatory strategies of xenogeneic immune rejection, and the optimization approaches of immune compatibility ...
