peptide c3a C3a is a 77 residue anaphylatoxin - Complement c3 C3a (70 - 77) is a peptide Understanding Peptide C3a: A Key Player in Immune Response and Beyond

C3b Peptide C3a, a significant fragment derived from the complement protein C3, plays a multifaceted role in the human body, primarily within the immune systemC3a (70-77) - 1 mg. This potent anaphylatoxin is generated through the cleavage of the alpha-chains of C3, a critical component of the complement cascade. The resulting peptide fragment, often referred to as human anaphylatoxin C3a, is a relatively small molecule, approximately 10 kDa in size, and is recognized for its involvement in a wide array of biological processes.

The primary function of peptide C3a is its ability to bind to the C3a receptor (C3aR), a type of G protein-coupled receptor作者：JM Harder·2020·被引用次数：45—Conclusions.C3AR1 was identified as a damaging neuroinflammatory factor.

Beyond its inflammatory functions, peptide C3a also exhibits other significant biological activities. It is known to stimulate smooth muscle contraction and platelet aggregation.C3a (complement) Moreover, this peptide has been shown to exert antimicrobial effects, contributing to the innate immune system's ability to combat pathogens. The complement C3a peptide is a native, single chain C3a complement component that is crucial for various immune responses.

The intricate nature of peptide C3a has led to extensive research into its structure and function. Various synthetic peptides and analogs have been developed to study its specific activities. For example, C3a (70 - 77) is a peptide that represents a C-terminal fragment of C3a anaphylatoxin peptide. While this shorter peptide possesses some biological activity, it is generally considered to have a reduced potency compared to the full C3a molecule. These synthetic peptides are invaluable tools for researchers investigating the precise mechanisms by which C3a interacts with its receptor and elicits its diverse effects. Some of these synthetic analogs are designed to act as an agonist to the C3a receptor, allowing for targeted studies of receptor activation作者：JM Harder·2020·被引用次数：45—Conclusions.C3AR1 was identified as a damaging neuroinflammatory factor.
