Site‐specific mutagenesis of residues in the human C5a anaphylatoxin which are involved in possible interaction with the C5a receptor [PDF]

European Journal of Biochemistry, 1994
To check and clarify existing data on receptor‐interacting residues in the human C5a anaphylatoxin, we tested mutant C5a proteins obtained by site‐directed mutagenesis of a recombinant human C5a (rhC5a) cDNA clone for structural and functional integrity.

Acute anaphylactic and multiorgan inflammatory effects of Comirnaty in pigs: evidence of spike protein mRNA transfection and paralleling inflammatory cytokine upregulation

British Journal of Pharmacology, Volume 183, Issue 20, Page 6225-6239, October 2026.
Abstract Background and Purpose Rare but severe adverse events (AEs) associated with mRNA‐lipid nanoparticle (LNP) COVID‐19 vaccines, such as Comirnaty, include anaphylaxis and inflammatory organ disorders, but their underlying mechanisms are poorly understood. We aimed to develop an animal model to study these phenomena.

A First‐in‐Japanese Phase 1, Double‐Blind, Placebo‐Controlled, Parallel‐Cohort Study of Sefaxersen, an Antisense Oligonucleotide Targeting Complement Factor B, in Healthy Participants

Clinical Pharmacology in Drug Development, Volume 15, Issue 9, September 2026.
Abstract Increased activity in the complement alternative pathway (AP) plays a key role in diseases such as IgA nephropathy (IgAN). This first‐in‐Japanese double‐blind Phase 1 study investigated the pharmacokinetics (PK), pharmacodynamics (PD), safety, and tolerability of sefaxersen (RO7434656), an antisense oligonucleotide targeting complement factor ...

Cancer cell‐selective ectopic expression of CD20 as an antigen enables rituximab repurposing for solid tumour immunotherapy

Clinical and Translational Medicine, Volume 16, Issue 9, September 2026.
A recombinant AAV delivered tumour gene therapy. NF‐κB drives tumour‐selective antigen (e.g., CD20) expression. Ectopic CD20 enables rituximab repurposing to solid tumours. ADCC, ADCP, and CDC contribute to the antitumour activity. Abstract Background Despite the clinical success of cancer immunotherapies, their efficacy is often compromised by antigen‐

Targeting complement anaphylatoxin C5a receptor in hyperoxic lung injury in mice

Molecular Medicine Reports, 2014
Receptor binding of complement anaphylatoxin C5a results in proinflammatory activation of numerous diseases, but the role of receptor-mediated action during hyperoxic lung injury has, to the best of our knowledge, not yet been investigated. The contribution of the C5a receptor (C5aR) to hyperoxic lung injury in mice was investigated in this study.

Cytokine‐Driven Hyperinflammation in Long COVID: Mechanisms, Biomarkers, Complement Dysregulation, and Emerging Immunotherapies—A Narrative Review

Health Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background and Aims Long COVID, also known as post‐acute sequelae of SARS‐CoV‐2 infection (PASC), is a multisystem condition characterized by persistent symptoms that continue beyond the acute phase of infection. Growing evidence indicates that sustained immune dysregulation involving cytokine‐mediated inflammation, complement activation ...

Role of the complement anaphylatoxin C5a-receptor pathway in atopic dermatitis in mice

Molecular Medicine Reports, 2015
Atopic dermatitis (AD) is a chronic inflammatory skin disease with a genetic background. The C5a‑receptor (C5aR) pathway has been reported to be involved in AD; however, the precise pathogenesis remains to be elucidated. In the present study, the contribution of the C5aR pathway to AD in mice was investigated.

Labile Heme Aggravates Renal Inflammation and Complement Activation After Ischemia Reperfusion Injury

Frontiers in Immunology, 2019
Background: Ischemia reperfusion injury (IRI) plays a major role in solid organ transplantation. The length of warm ischemia time is critical for the extent of tissue damage in renal IRI.

Thromboinflammatory biomarkers in obstetric pathophysiology: Predictive insights into placental insufficiency and feto‐maternal adverse outcomes

Clinical and Translational Discovery, Volume 6, Issue 4, August 2026.
Placental insufficiency is a thromboinflammatory disorder driven by angiogenic imbalance, complement activation, endothelial dysfunction and coagulation dysregulation, leading to microvascular thrombosis, impaired uteroplacental perfusion and adverse maternal and fetal outcomes, including pre‐eclampsia, fetal growth restriction and stillbirth.
