Abstract

Atherosclerosis (AS) is a common pathological basis for many cardiovascular diseases (CVDs) and result in high mortality and immense health and economic burdens worldwide. Early prevention, diagnosis, and treatment are promising approaches for stemming the development and progression of AS. Lactoferrin (Lf) is an iron-binding glycoprotein belonging to the transferrin family. It is widely found in body fluids such as digestive tract fluids, tears, and milk. Lf possesses anti-inflammatory, antibacterial, immunoregulatory, antioxidant and many other physiological functions. The serum Lf level is reportedly associated with the risk of AS and AS-related CVDs. Lf administration is closely involved in several mechanisms, including cholesterol metabolism, foam cell formation, ICAM-1 expression, homocysteine and leptin levels, anti-inflammatory and antioxidant function. Moreover, Lf has also been applied in the sythesis of magnetic resonance imaging (MRI) contrast agents to detect AS. Lf plays an important role in AS and may therefore be used in its diagnosis and treatment. Thus, this article aims to review the association between Lf and the risk of AS and AS-related CVDs, the mechanisms of Lf administration on AS, and its potential application in AS diagnosis.
