Abstract: Haptoglobin(Hp) is a multifunctional plasma glycoprotein which plays a critical role in several physiological and pathological processes, particularly in the context of infection and sepsis. This review provides a comprehensive examination of diverse functions of Hp. It focuses on its role aspositive acute phase response protein, its involvement in management of free hemoglobin, modulation of the immune response and its potential as a biomarker for a wide range of diseases. The review outlines Hp ability to bind and clear free hemoglobin which helps to prevent oxidative damage, while its immunoregulatory properties contribute to the body’s defense against pathogens during infection and sepsis. Additionally, the article discusses the growing interest in Hp as a potential diagnostic and prognostic biomarker for various conditions, including infectious diseases, sepsis, and role of Hp in protein glycosylation. Recent studies have also emphasized the role of Hp in the stimulation of the inflammasome which is a key component of the innate immune response, further underscoring its multifaceted involvement in the body’s defense mechanisms. By examining the current understanding of Hp multifaceted functions, we highlight the importance of further research into this versatile acute phase protein and its clinical implications.
