C-reactive protein (CRP) is a pentraxin family protein involved in several host defense-related functions as a result of its ability to bind to foreign pathogens and damaged host cells (1). CRP is a cyclic, non-covalent pentameric protein and normal constituent of human sera that is produced primarily by hepatocytes (2). Secretion of CRP is induced by proinflammatory cytokines, including IL-6 and IL-1β, and significantly increases during acute phase responses to tissue injury, infection, or other inflammatory stimuli (3,4). The presence of CRP is often utilized as an inflammation marker, and monitoring CRP levels in plasma is a useful tool in assessing disease progression or treatment effectiveness. CRP is also regarded as a risk assessment factor for the development and progression of cardiovascular disease (5).

CRP binds to phosphorylcholine that is present on the surface of damaged tissues and in the bacterial cell wall of certain pathogens (6). Through this calcium-dependent interaction, CRP promotes agglutination and initiates the activation of the complement cascade. This results in enhanced opsonization through CRP interaction with FcγRI and FcγRIIA, which facilitates phagocytosis (7).
