AI Technical Summary
Current treatments for cardiovascular diseases, such as statins and PCSK9 inhibitors, only modestly reduce levels of atherogenic apoB-containing lipoproteins like VLDL, IDL, Lp(a), chylomicron, and chylomicron remnants, leaving residual cardiovascular risk in populations with controlled LDL cholesterol levels.
Development of recombinant tissue plasminogen activator kringle 2 domain (tPA-K2) fragments that bind to apolipoprotein B, inhibit its secretion, and disrupt lipidation, potentially lowering plasma levels of these lipoproteins, using nucleotide sequences encoding tPA-K2 polypeptides delivered via vectors like adeno-associated virus or lipid nanoparticles.
The tPA-K2 fragments effectively reduce plasma levels of atherogenic apoB lipoproteins, including VLDL, IDL, Lp(a), and chylomicron remnants, thereby lowering triglycerides and cholesterol, providing a new therapeutic approach for treating cardiovascular diseases.
