Abstract: Aspects of the disclosure relate to complexes comprising a muscle-targeting agent covalently linked to a molecular payload. In some embodiments, the muscle-targeting agent specifically binds to an internalizing cell surface receptor on muscle cells. In some embodiments, the molecular payload promotes the expression or activity of a functional dystrophin protein. In some embodiments, the molecular payload is an oligonucleotide, such as an antisense oligonucleotide, e.g., an oligonucleotide that causes exon skipping in a mRNA expressed from a mutant DMD allele.

Abstract: Provided in the present application are an antibody against factor XIa in the activated form of coagulant factor XI, a preparation method therefor and the use thereof. The CDR of the heavy chain variable region of the antigen-binding fragment of the antibody comprises the amino acid sequence shown in SEQ ID NOs: 1-3, and the CDR of the light chain variable region thereof comprises the amino acid sequence shown in SEQ ID NOs: 4-6. The antibody can specifically bind to FXIa but not to FXI, and has the effect of inhibiting the endogenous pathway of human coagulation without affecting the exogenous pathway thereof, which can significantly inhibit the formation of arteriovenous shunt thrombosis, but does not increase the bleeding time and volume. Same has the potential to become an antithrombotic drug.
