LPA (Lipoprotein(a)) is a unique lipoprotein particle implicated in cardiovascular diseases, particularly atherosclerosis and aortic stenosis. Structurally, Lp(a) consists of a low-density lipoprotein (LDL)-like core bound to apolipoprotein(a) (apo(a)), a glycoprotein homologous to plasminogen. Apo(a)'s size polymorphism, caused by varying numbers of kringle IV type 2 repeats, creates individual variability in Lp(a) levels, which are genetically determined by the LPA gene. Elevated Lp(a) (>50 mg/dL) is recognized as an independent risk factor for cardiovascular events due to its pro-atherogenic and pro-thrombotic properties.
Recombinant Lp(a)-related proteins are engineered to study its pathophysiological mechanisms and develop targeted therapies. These proteins typically include modified apo(a) fragments or full-length variants expressed in mammalian cell systems. Key research focuses on Lp(a)'s ability to carry oxidized phospholipids, interact with vascular components, and inhibit fibrinolysis through plasminogen receptor competition. Recombinant proteins enable precise investigation of Lp(a)'s binding affinities, inflammatory signaling, and contributions to plaque instability.
Pharmaceutical interest centers on Lp(a)-lowering strategies, with recombinant proteins serving as tools for antibody development or antisense oligonucleotide validation. Recent clinical trials targeting Lp(a) reduction, such as pelacarsen (antisense oligonucleotide) and siRNA therapies, highlight the translational importance of recombinant Lp(a) models. Ongoing studies aim to clarify its role in lipid metabolism and refine cardiovascular risk stratification, particularly in patients resistant to conventional LDL-lowering treatments.
