C5a stimulation induces caspase-1 activation and mature IL-1β production in human peripheral blood mononuclear cells

Immunological Medicine
The complement component C5a contributes to the recruitment of immune cells to inflamed tissues and local inflammation. The proinflammatory cytokine interleukin (IL)-1β is also related to inflammatory disorders through inflammasome activation.

The relationship of anti-phospholipase A2 receptor antibody and C5a complement with disease activity and short-term outcome in idiopathic membranous nephropathy

Journal of the Formosan Medical Association, 2019
Background: The binding of anti-phospholipase A2 receptor (anti-PLA2R) antibody to podocyte and complement activation is the mechanisms of idiopathic membranous nephropathy (IMN).

Modulation of C5a–C5aR1 signaling alters the dynamics of AD progression

Journal of Neuroinflammation, 2022
Background The complement system is part of the innate immune system that clears pathogens and cellular debris. In the healthy brain, complement influences neurodevelopment and neurogenesis, synaptic pruning, clearance of neuronal blebs, recruitment of ...

The Endothelial CXCR Family in Vascular Health and Disease

iNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

Engineered extracellular vesicles for precision renal therapy: Bioengineering strategies and clinical translation

Interdisciplinary Medicine, EarlyView.
Engineered extracellular vesicles (EVs) offer a versatile platform for kidney‐targeted therapy. This review summarizes bioengineering strategies, including cargo loading, surface modification, biomimetic fabrication, and biomaterial integration. We highlight translational challenges and propose future solutions to accelerate the clinical application of

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.

Association of C5a/C5aR pathway to activate ERK1/2 and p38 MAPK in acute kidney injury – a mouse model

Romanian Journal of Laboratory Medicine, 2022
Acute inflammation is accompanied by complement system activation and inflammatory cell accumulation. Acute kidney injury (AKI) is one of the common clinical symptoms, it is not clear whether complement system-mediated signaling pathway is involved. This

Rescue with an anti-inflammatory peptide of chickens infected H5N1 avian flu [PDF]

, 2009
Chickens suffering from avian flu caused by H5N1 influenza virus are destined to die within 2 days due to a systemic inflammatory response. Since HVJ infection (1,2) and influenza virus infection (3,4) cause infected cells to activate homologous serum ...

Regulatory effects of C5a on IL-17A, IL-17F, and IL-23

Frontiers in Immunology, 2013
The complement anaphylatoxin, C5a, through binding to its receptors (C5aR or C5L2), has important biological properties for recruitment and activation of phagocytes.
