Functional Analysis of a Novel Complement C5a Receptor 1-Blocking Monoclonal Antibody
Journal of Innate Immunity, 2023 Introduction: The complement system anaphylatoxin C5a is a critical player in inflammation. By binding to complement C5a receptor 1 (C5aR1/CD88), C5a regulates many cellular functions, mainly as a potent pro-inflammatory inducer.

HSP90-Mediates Liraglutide Preconditioning-Induced Cardioprotection by Inhibiting C5a and NF-κB
Journal of Investigative Surgery, 2022 Objective We previously showed that HSP90 is involved in postconditioning cardioprotection by inhibiting complement C5a. Here, we investigated whether HSP90-mediated C5a/NF-κB inhibition is responsible for the cardioprotection conferred by liraglutide ...

Inactivation of C5a Anaphylatoxin by a Peptide That Is Complementary to a Region of C5a [PDF]
The Journal of Immunology, 2004 Abstract PL37 (RAARISLGPRCIKAFTE) is an antisense homology box peptide composed of aa 37–53 of C5a-anaphylatoxin and is considered to be the region essential for C5a function. Using a computer program, we designed the complementary peptides ASGAPAPGPAGPLRPMF (Pep-A) and ASTAPARAGLPRLPKFF (Pep-B).

Persistence of High Levels of Serum Complement C5a in Severe COVID-19 Cases After Hospital Discharge
Frontiers in Immunology, 2021 Evidence supports a role of complement anaphylatoxin C5a in the pathophysiology of COVID-19. However, information about the evolution and impact of C5a levels after hospital discharge is lacking. We analyzed the association between circulating C5a levels
