Associations between CSF complement factors and biomarkers of amyloid, tau, neurofilament light chain, and α‐synuclein in AD, DLB, and PD

Alzheimer's &Dementia, Volume 21, Issue S2, December 2025.
Abstract Background While evidence suggests complement system involvement in Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and Parkinson's disease (PD), its association with disease biomarkers remains unclear. We investigated the relationship of complement factors with amyloid, tau, NfL, and α‐synuclein in CSF in AD, DLB, PD, and controls.

Protective role for properdin in progression of experimental murine atherosclerosis.

PLoS ONE, 2014
Genetic, dietary and immune factors contribute to the pathogenesis of atherosclerosis in humans and mice. Complement activation is an integral part of the innate immune defence but also shapes cellular responses and influences directly triglyceride ...

Cellular Communication Networks Mediated by Microglia in Ischemic Stroke

CNS Neuroscience &Therapeutics, Volume 31, Issue 12, December 2025.
After ischemic stroke, microglia serve as central regulators within the neuroimmune network, engaging in dynamic crosstalk with neurons, astrocytes, vascular endothelial cells, and peripheral immune cells. By releasing cytokines, chemokines, extracellular vesicles, and transmitting mechanical signals, activated microglia coordinate inflammatory ...

Invasive Meningococcal Disease in a Patient With Complement 7 Deficiency

Journal of General and Family Medicine, Volume 26, Issue 6, Page 646-649, November 2025.
ABSTRACT Neisseria meningitidis can cause invasive meningococcal disease (IMD). Individuals with primary complement deficiencies are at a higher risk of developing IMD. However, cases of IMD associated with complement deficiency have rarely been reported in Japan.

Human Properdin Opsonizes Nanoparticles and Triggers a Potent Pro-inflammatory Response by Macrophages without Involving Complement Activation

Frontiers in Immunology, 2018
Development of nanoparticles as tissue-specific drug delivery platforms can be considerably influenced by the complement system because of their inherent pro-inflammatory and tumorigenic consequences.

The Properdin System in Mice.

Experimental Biology and Medicine, 1960
SummaryInjection of complement (guinea pig serum) into the laboratory albino mouse failed to alter capacity of these animals to withstand parenterally induced bacterial infection with K. pneumoniae or S. typhimurium. Addition of complement to mouse serum failed to induce bactericidal activity in vitro.

Immunoglobulin A Nephropathy: Molecular Pathogenesis and Targeted Therapy

MedComm, Volume 6, Issue 9, September 2025.
The future of IgAN treatment likely involves combining several therapies to target multiple disease mechanisms simultaneously. Clinical trials are ongoing to evaluate the efficacy and safety of various combinations. As our understanding of IgAN pathogenesis evolves, more targeted and personalized treatment strategies are expected to emerge.

Low molecular weight polysialic acid binds to properdin and reduces the activity of the alternative complement pathway

Scientific Reports, 2022
Sialic acids as the terminal caps of the cellular glycocalyx play an essential role in self-recognition and were shown to modulate complement processes via interaction between α2,3-linked sialic acids and complement factor H. Previously, it was suggested

Unraveling the Molecular Mechanisms Underlying Complement Dysregulation by Nephritic Factors in C3G and IC-MPGN

Frontiers in Immunology, 2018
Membranoproliferative glomerulonephritis (MPGN) was recently classified as C3 glomerulopathies (C3G), and immune-complex (IC) mediated MPGN. Dysregulation of the complement alternative pathway, driven by acquired and/or genetic defects, plays a ...

Short‐Term Severe Energy Restriction Promotes Molecular Health and Reverses Aging Signatures in Adults With Prediabetes in the PREVIEW Study

Aging Cell, Volume 24, Issue 8, August 2025.
Severe short‐term energy restriction in adults with prediabetes led to a significant reduction in circulating proteins linked to inflammation, senescence, and protein turnover. These changes, partly mediated by extracellular vesicles, suggest systemic dietary‐induced benefits beyond glycemic control, including improved aging biomarkers.
