Complement component C1q is produced by isolated articular chondrocytes [PDF]

Osteoarthritis and Cartilage, 2020
Inflammation and innate immune responses may contribute to development and progression of Osteoarthritis (OA). Chondrocytes are the sole cell type of the articular cartilage and produce extracellular-matrix molecules. How inflammatory mediators reach chondrocytes is incompletely understood.

Astrocytic Phenotypic Switching in Posterior Piriform Cortex Orchestrates Bone Cancer Pain–Depression Comorbidity via Purinergic–Noradrenergic Signaling

Advanced Science, EarlyView.
Bone cancer pain and depression share a common origin: astrocytic A2‐to‐A1 transition in the posterior piriform cortex. This phenotypic shift disrupts the ATP–adenosine–A2AR–norepinephrine axis, simultaneously driving nociceptive and affective dysfunction.

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

Advanced Science, EarlyView.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

C1q and the classical complement cascade in geographic atrophy secondary to age-related macular degeneration

International Journal of Retina and Vitreous, 2022
Geographic atrophy (GA) secondary to age-related macular degeneration (AMD) is a retinal neurodegenerative disorder. Human genetic data support the complement system as a key component of pathogenesis in AMD, which has been further supported by pre ...

A Blood‐Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN‐Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1

Advanced Science, EarlyView.
Systemic platelet factor 4 (PF4) is significantly depleted in amyotrophic lateral sclerosis (ALS). Peripheral PF4 replenishment restores central proteostasis by driving OPTN‐dependent, PINK1‐independent selective autophagy in motor neurons. This intervention effectively clears toxic SOD1 aggregates, blunts glial activation, and preserves neuromuscular ...

Animal models of idiopathic membranous nephropathy: Recent advances and future perspectives

Animal Models and Experimental Medicine, EarlyView.
This review focuses on the evolution of idiopathic membranous nephropathy (IMN) animal models from traditional approaches (Heymann nephritis, C‐BSA, APA) to antigen‐specific models (PLA2R, THSD7A), critically evaluating their advances and limitations in replicating human IMN pathology.

Proinflammatory Epstein–Barr Virus Antibody Functions Track with Disease Activity in Multiple Sclerosis

Annals of Neurology, EarlyView.
Objective Epstein–Barr virus (EBV) has been implicated in the pathogenesis of multiple sclerosis (MS). Elevated immunoglobulin G (IgG) titers against EBV nuclear antigen 1 (EBNA1) represent the most consistent serological marker of MS risk, with levels remaining persistently elevated following disease onset.

Novel C1q receptor-mediated signaling controls neural stem cell behavior and neurorepair

eLife, 2020
C1q plays a key role as a recognition molecule in the immune system, driving autocatalytic complement cascade activation and acting as an opsonin. We have previously reported a non-immune role of complement C1q modulating the migration and fate of human ...

Immune Complexes Shape the Pathogenicity of Autoantibodies in Systemic Autoimmune Diseases: Insights From an FcγRIIIA‐Reporter Assay

Arthritis &Rheumatology, EarlyView.
Objective Immune complexes (ICs), formed by autoantigen and autoantibody, play a pathogenic role in systemic autoimmune diseases through stimulation of Fcγ receptors (FcγR). However, studies investigating bioactivity of circulating ICs across various diseases remain limited.

Correlation of Serum Anti-Clq Antibody Levels and Disease Activity in Patients with Systemic Lupus Erythematosus

Indonesian Journal of Rheumatology, 2019
Background. Antibody to complement C1q (Anti-C1q Antibody) can be found in Systemic Lupus Erythematosus (SLE) patients. Complement C1q plays a role in the clearance of apoptotic cells and immune complexes.
