  • Patent number: 12570740
    Abstract: Antibodies to the enzyme matriptase-2 (MTP-2) are presented. Inhibiting MTP-2 reduces uptake of dietary iron and reduces the release of iron from cellular stores in the body. Inhibitors of MTP-2 (such as antibodies to the serine protease domain) can be used to treat iron overload, which is a feature of diseases such as beta-thalassaemia and which otherwise leads to toxic accumulation of iron. Combination of an MTP-2 inhibitor with an activin receptor ligand trap, or with erythropoietin, provides additional therapeutic effects.

  • Patent number: 12473378
    Abstract: Antibodies comprising unpaired variable domains, e.g., heavy chain variable (VH) domains, for binding antigen. Antibody comprising two immunoglobulin (Ig) chains, wherein a first Ig chain comprises a variable domain and a constant domain, and a second Ig chain comprises a constant domain, wherein the second Ig chain lacks a variable domain, leaving the variable domain of the first Ig chain unpaired. The antibody may comprise two Ig heavy chains and two Ig light chains, each heavy chain comprising a VH domain and a constant region comprising a CH1 domain, and each light chain comprising a CL domain, wherein one or both light chains lack a VL domain, thereby leaving one or both VH domains unpaired. Non-human animals (e.g., mice) engineered to produce antibodies having unpaired VH domains, involving deletion of sequence coding for light chain variable (VL) domains. Use of unpaired VH domains to generate antigen-binding molecules.

  • Patent number: 11920128
    Abstract: The invention relates to an approach for introducing one or more desired insertions and/or deletions of known sizes into one or more predefined locations in a nucleic acid (eg, in a cell or organism genome). They developed techniques to do this either in a sequential fashion or by inserting a discrete DNA fragment of defined size into the genome precisely in a predefined location or carrying out a discrete deletion of a defined size at a precise location. The technique is based on the observation that DNA single-stranded breaks are preferentially repaired through the HDR pathway, and this reduces the chances of indels (eg, produced by NHEJ) in the present invention and thus is more efficient than prior art techniques. The invention also provides sequential insertion and/or deletions using single- or double-stranded DNA cutting.
