The present invention provides antagonizing antibodies, antigen-binding portions thereof, and aptamers that bind to proprotein convertase subtilisin kexin type 9 (PCSK9). Also provided are antibodies directed to peptides, in which the antibodies bind to PCSK9. The invention further provides a method of obtaining such antibodies and antibody-encoding nucleic acid. The invention further relates to therapeutic methods for use of these antibodies and antigen-binding portions thereof to reduce LDL-cholesterol levels and / or for the treatment and / or prevention of cardiovascular disease, including treatment of hypercholesterolemia.

Antagonists of human proprotein convertase subtilisin-kexin type 9 (“PCSK9”) are disclosed. The disclosed antagonists are effective in the inhibition of PCSK9 function and, accordingly, present desirable antagonists for use in the treatment of conditions associated with PCSK9 activity. The present invention also discloses nucleic acid encoding said antagonists, vectors, host cells, and compositions comprising the antagonists. Methods of making PCSK9-specific antagonists as well as methods of using the antagonists for inhibiting or antagonizing PCSK9 function are also disclosed and form important additional aspects of the present disclosure.

The disclosure relates to a filamentous fungal cell in which an endogenous alkaline protease activity, an endogenous neutral metalloprotease activity, an endogenous serine protease activity, and an endogenous kexin maturase activity have been completely or partially inactivated. Particularly the endogenous alkaline protease activity, the endogenous.neutral metalloprotease activity, the endogenous serine protease activity, and the kexin maturase activity are encoded by the alp, npI, pepC and kexB genes respectively. The filamentous fungal cell is particularly suitable for production of heterologous proteins such as antibodies.

A chimera protein comprising in the following order: a signal peptide, a proprotein convertase subtilisin / kexin type 9 preproprotein (PCSK9) sequence consisting of amino acid residues at positions 35 to 696 of SEQ ID NO: 38, a transmembrane domain and a cytosolic domain, wherein said cytosolic (CT) domain comprises a sequence able to recycle the protein from the cellular membrane to endosomes.

The invention discloses a construction method of a gene detection library of familial hypercholesterolemia and a gene detection kit and relates to gene mutation of LDLR (Low-Density Lipoprotein Receptor), APOB (Apolipoprotein B) and PCSK9 (Proprotein Convertase Subtilisin / Kexin type 9). In order to ensure that all target regions (including an entire coding region and an alternative splicing regionof a gene to be detected) are covered and prevent a primer dimer or a short segment from being formed between primers of adjacent amplicons, a PCR (Polymerase Chain Reaction) amplification primer isdivided into two independent primer pools; then primer sequence digestion, sequencing connector connection, library purification and quality detection are carried out; finally, the detection library is constructed. The method has the advantages that library establishment steps are simple and rapid, the cost is effectively reduced, the working amount is reduced, variation types are comprehensive, the detection accuracy reaches 100 percent and the flux is high.

A method for treating and / or preventing a proprotein convertase subtilisin / kexin type 9 preproprotein (PCSK9)-susceptible viral infection comprising increasing a PCSK9 activity and / or expression in a biological system infected by the virus, whereby the increased PCSK9 activity and / or expression treats and / or prevents the viral infection in the biological system. Methods of classifying subjects, methods of screening and kits therefore.

The present invention provides methods and compositions for inhibiting atherosclerotic plaque formation in a subject. In certain embodiments, the methods of the present invention comprise selecting a subject who has, or is at risk of developing, atherosclerosis, and administering to the subject a pharmaceutical composition comprising a proprotein convertase subtilisin / kexin type 9 (PCSK9) inhibitor. In certain embodiments, this PCSK9 inhibitor is an anti-PCSK9 antibody, or antigen binding protein.

The present invention provides methods for treating a PCSK9-mediated disease or a PCSK9-mediated condition. Specifically, the invention relates to methods comprising the administration of a proprotein convertase subtilisin / kexin type 9 (PCSK9) antibody or antigen binding protein, in the absence of a statin, to a subject in need thereof.
