C5a車 The c5a peptide is a pivotal molecule within the body's intricate defense system, the complement system.C5a is crucial to triggering cellular immune responsesand its overexpression is involved in arthritis, Alzheimer's disease, cystic fibrosis. This potent peptide, also known as complement component 5a, anaphylatoxin C5a, or peptide C5a, serves as an integral component of the complement system. Its primary functions revolve around orchestrating inflammatory responses and facilitating the elimination of pathogens. The c5a peptide is generated through the cleavage of complement component C5 by the enzyme C5 convertase, resulting in two fragments: C5a and C5b. Specifically, C5a emerges as a powerful mediator of inflammation, playing a critical role in both pathogen clearance and immunomodulation.作者：M Ghosh·2024·被引用次数：7—C5a recruits receptors like C5aR1 and C5aR2and is established to play a critical role in complement-mediated inflammation.
