The disclosure relates to therapeutic proteins and pharmaceutical compositions comprising said proteins, which have utility in treating various human diseases. In particular aspects, the disclosed therapeutic proteins are useful for treating human gastrointestinal inflammatory diseases and gastrointestinal conditions associated with decreased epithelial cell barrier function or integrity. Further, the disclosed therapeutic proteins are useful for treating human inflammatory bowel disease, including inter alia, Crohn's disease and ulcerative colitis.

Disclosed are a chimeric antigen receptor (CAR) targeting CLD18A2, and preparation method and use thereof. The extracellular binding region of the CAR comprises a protein specifically recognizing CLD18A2. The immune effector cell modified by the CAR can be used to treat tumors such as pancreatic cancer and stomach cancer.

The present invention is based, in part, on the novel discovery of the architecture and assembly pathway of three different classes of mammalian SWI/SNF complexes, compositions comprising the isolated modified SWI/SNF complexes, and methods of screening for modulators of the function and/or stability of same.

Disclosed herein are antibodies and compositions used for binding to Gal3. Some embodiments allow for disrupting interactions between Galectin-3 (Gal3) and cell surface markers and/or proteins associated with neurological diseases and/or proteopathies, such as Alzheimer's disease. Additionally, disclosed herein are methods of treatment and uses of the antibodies or binding fragments thereof for the treatment of fibrosis, liver fibrosis, kidney fibrosis, cardiac fibrosis, pulmonary fibrosis, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, sepsis, atopic dermatitis, psoriasis, cancer, brain cancer, breast cancer, colorectal cancer, kidney cancer, liver cancer, lung cancer, pancreatic cancer, bladder cancer, stomach cancer, hematological malignancy, neurological diseases and/or proteopathies. Furthermore, some embodiments provided herein can cross the blood-brain barrier and can be conjugated or otherwise associated with one or more payloads for the treatment of a neurological disease.

The present application provides chimeric antibody-TCR constructs comprising an antigen-binding module that specifically binds to a target antigen and a T cell receptor module capable of recruiting at least one TCR-associated signaling molecule. Also provided are methods of making and using these constructs.

Provided herein are immunomodulatory proteins comprising ICOSL variants and nucleic acids encoding such proteins. The immunomodulatory proteins provide therapeutic utility for a variety of immunological and oncological conditions. Compositions and methods for making and using such proteins are provided.

Compositions, methods, and systems for modifying sterol metabolism in a subject is disclosed. In some embodiments, the subjects may be administered one or more mammalian cells modified to express at least one sterol degrading enzyme derived from a bacterium. In many embodiments, the cell is a macrophage or monocyte stably expressing three or more enzymes that aid in opening the β ring of cholesterol. The disclosed compositions and methods may be useful in lowering cholesterol levels in a subject in need thereof. In some embodiments, the subject may have a genetic predisposition to atherosclerosis.

Provided herein are methods and compositions for producing alpha-N-methylated peptides in vitro and in vivo. This disclosure also provides in vivo and in vitro methods for producing highly diverse alpha-N-methylated peptide libraries by methylating natural or non-natural alpha-N-methyltransferase target peptides.

Provided herein are compositions and methods to make and use engineered cells, for the purpose of increasing the cell density of a culture comprising metazoan cells and for the production of a cultured edible product.

The present invention relates to a humanized DR4 antibody gene having apoptosis-inducing activity, and a dual-acting chimeric antigen receptor T cell or natural killer cell therapeutic agent, a secretory DR4 scFv antibody recombinant protein synthesized by using a humanized DR4 scFv antibody gene (humanized anti-DR4 scFv) may be used as an anticancer drug specifically targeting DR4 by binding to DR4 expressed on surface of the cancer cells to induce apoptosis of the cancer cells. In addition, the chimeric antigen receptor (CAR) using the humanized DR4 scFv antibody gene is predicted to have a strong anticancer immune effect as a dual-acting cell therapeutic agent, which is capable of simultaneously inducing apoptosis in cancer cells by DR4 and exhibiting a cytotoxic effect for cytotoxic T lymphocytes or natural killer cells by binding to DR4 expressed on the surface of cancer cells, as a DR4-specific CAR-T cell or CAR-NK cell therapeutic agent.
