Complement Component 3a (C3a) Antibody Pair

Background

Complement C3 is a central component of the complement system, an essential part of the innate immune response that aids in the clearance of pathogens and the regulation of inflammation C3 is involved in all three complement pathways (classical, alternative, and lectin), playing a critical role in immune defense by promoting opsonization, cell lysis, and inflammation activation Upon cleavage into C3a and C3b, C3a acts as an inflammatory mediator, and C3b binds to pathogens to mark them for destruction by phagocytes Complement C3 deficiency or dysfunction is associated with various autoimmune diseases, such as systemic lupus erythematosus (SLE), and with susceptibility to infections C3 is also involved in the regulation of adaptive immunity, influencing antibody production and T-cell responses Its role in inflammation, pathogen clearance, and immune system regulation highlights its importance in maintaining immune balance and tissue homeostasis
