The present disclosure relates to genetically modified non-human animals that express a fusion protein including B2M and FcRn, and methods of use thereof. In some embodiments, the animals can have a B-NDG background. In some embodiments, the endogenous B2M gene is knocked out in the animals.

Provided are improved compositions and methods for achieving gene therapy in hematopoietic cells and hematopoietic precursor cells, including erythrocytes, erythroid progenitors, and embryonic stem cells. Also provided are improved gene therapy methods for treating hematopoietic-related disorders. Retroviral gene therapy vectors that are optimized for erythroid specific expression and treatment of hemoglobinopathic conditions are disclosed.

Methods of generating spinal cord glutamatergic interneurons (V2a interneurons) from human pluripotent stem cells (hPSCs) are provided. A method of the present disclosure may include culturing a first population of hPSCs in vitro in a neural induction medium that includes: a retinoic acid signaling pathway activator; a sonic hedgehog (Shh) signaling pathway activator; and a Notch signaling pathway inhibitor, wherein the culturing results in generation of a second population of cultured cells containing CHX10+ V2a interneurons. Also provided are non-human animal models that include the hPSC-derived spinal cord glutamatergic interneurons, and methods of producing the non-human animal models.

The present disclosure provides multispecific antigen-binding molecules capable of binding to CD3 and CD137 (4-1BB) but not binding to CD3 and CD137 at the same time, and capable of binding to CLDN6. The multispecific antigen-binding molecules of the present disclosure exhibit enhanced T-cell dependent cytotoxicity activity in a CLDN6-dependent manner through binding to the CD3/CD37 and CLDN6. The present invention provides multi-specific antigen-binding molecules and pharmaceutical compositions thereof that can be used for targeting cells expressing CLDN6, for use in immunotherapy for treating various cancers, especially those associated with CLDN6 such as CLDN6-positive cancers.

In order to develop tools and methods useful in a variety of applications, including the research and development of medical treatments which involve the modification of collagen protein and use of the same, the present invention provides a modified collagen protein expressed in a transformed cell and capable of forming collagen fibers outside of the cell, wherein the transformation is performed by introducing, into the cell, polynucleotides coding the modified collagen protein.

Genetically modified non-human animals are provided that exhibit a functional lack of one or more lncRNAs. Methods and compositions for disrupting, deleting, and/or replacing lncRNA-encoding sequences are provided. Genetically modified mice that age prematurely are provided. Also provided are cells, tissues and embryos that are genetically modified to comprise a loss-of-function of one or more lncRNAs.

The present invention relates to a product comprising (i) an anti-VEGF entity; and (ii) a negative complement regulator, or nucleotide sequences encoding therefor, as a combined preparation for simultaneous, separate or sequential use in therapy. In particular, the anti-VEGF entity is an anti-VEGF antibody, preferably aflibercept and the negative complement regulator is Complement Factor I (CFI) or Complement Factor H Like Protein 1 (FHL1). The main uses are for the treatment of eye diseases, in particular age-related macular degeneration (AMD).

A method for screening an active ingredient of a saltiness enhancer, the screening method including the following steps: (i) a step for determining whether a test substance is a compound capable of promoting functional expression of the TMC4 gene or TMC4 protein; and (ii) a step for selecting, as an active ingredient of a saltiness enhancer, a test substance that has been determined in step (i) to be a compound capable of promoting functional expression of the TMC4 gene or TMC4 protein.

The disclosure in some aspects relates to recombinant adeno-associated viruses having distinct tissue targeting capabilities. In some aspects, the disclosure relates to gene transfer methods using the recombinant adeno-associated viruses. In some aspects, the disclosure relates to isolated AAV capsid proteins and isolated nucleic acids encoding the same.

The present disclosure relates to methods and compounds for promoting anabolic pathways in neuronal cells leading to improved neuronal survival. In particular, the present disclosure relates to inhibiting PHD to promote glycolysis and neuronal survival in a variety of neurodegenerative conditions such as retinitis pigmentosa.
