The present disclosure relates to the genetically modified non-human animals that express a human or chimeric OX40, and methods of use thereof.

Described here are methods, compositions, and systems for generating transgenic islet cells suitable for xenotransplantation.

Provided herein are methods for enhancing survival of a neuron, for inhibiting degeneration of a neuron, and for inhibiting abnormal protein accumulation in a neuron, optionally a motor neuron, comprising, consisting or consisting essentially of increasing the level of cyclin F in the neuron regardless of the neuron's level or activity of endogenous cyclin F. Optionally the neuron is in a subject with a neurodegenerative condition or at risk of developing a neurodegenerative condition, typically a neurodegenerative condition associated with a neuronal TDP-43 proteinopathy.

A preparation method of an anti-PD-1/PD-L1 monoclonal antibody (mAb)-induced autoimmune myocarditis model is provided, including: mediating a model with adeno-associated virus 9 (AAV9) to achieve the high expression of PDL1 in a myocardial tissue, and applying an anti-PD-1/PD-L1 mAb to the model with high PDL1 expression in the myocardial tissue for modeling. The present disclosure also provides use of an animal model prepared by the preparation method. The model prepared by the present disclosure truly simulates the pathogenesis and clinical course of autoimmune myocarditis in a patient administered with an anti-PD1/PD-L1 mAb, is close to a pathophysiological status of a clinical patient, has a high modeling rate, and can be dynamically monitored.

A method of treating cancer includes administering a dose of a chemotherapy agent in combination with a dose of a composition consisting essentially of attenuated Salmonella typhimurium. The dose of the chemotherapy agent is lower than a maximum effective dose of the chemotherapy agent. The combination provides a synergistic reduction in tumor burden when compared to the reduction in tumor burden provided by administration of an equivalent dose of the chemotherapy agent without the composition consisting essentially of attenuated Salmonella typhimurium.

Provided is an invention that is based on the novel function of a transcription factor RP58 in cells of the central nervous system. The present invention relates to: a transgenic non-human animal capable of increasing or decreasing the expression of the transcription factor RP58 in cells of the central nervous system of a non-human animal in the nascent stage and/or during and after the developmental stage; and a pharmaceutical composition for use in the treatment or prevention of brain dysfunction, or behavioral disorder, or a disease related thereto, wherein the pharmaceutical composition comprises a transcription factor RP58 protein, or a gene encoding the transcription factor RP58; etc.

Compositions and methods for editing, e.g., introducing double-stranded breaks, within the TTR gene in combination with administration of a corticosteroid are provided. Compositions and methods for treating subjects having amyloidosis associated with transthyretin (ATTR), in which a guide RNA and a corticosteroid are administered, are provided.

The present invention provides PiggyBac transposase proteins, nucleic acids encoding the same, compositions comprising the same, kits comprising the same, non-human transgenic animals comprising the same, and methods of using the same.

The present discloses relates to a composition, a kit or a method using an eIF4E inhibitor for diagnosis or treatment of a condition associated with increased activity of eIF4E.

The present invention relates to recombinant laminin adeno-associated viral vector (AAV) constructs and related methods for restoring laminin expression in deficient mammals, or in mammals with basement membrane instability.
