  • Publication number: 20220363751
    Abstract: 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.

  • Patent number: 11479603
    Abstract: An antibody for being specifically bound to a pro brain-derived neurotrophic factor (pro-BDNF) and a bound epitope. The antibody and the protein are used for treating autoimmune diseases. By inhibiting the activity induced by the pro-BDNF, rheumatoid arthritis, psoriasis, systemic lupus erythematosus, lupus nephriti, chronic obstructive pulmonary diseases, asthma or cystic fibrosis, multiple sclerosis and other autoimmune diseases are treated.

  • Publication number: 20220064274
    Abstract: Disclosed is a use of a proBDNF regulator in B cell-related diseases. Specifically, disclosed is a use of a reagent which suppresses or activates proBDNF activity or proBDNF signaling pathways in preparing a regulator which regulates B lymphocyte function. Also disclosed is a use of a regulator in preparing a drug which treats B lymphocyte dysfunction-related diseases, a use of an antibody in preparing a reagent or reagent kit which detects/treats B lymphocyte dysfunction-related diseases, and a method for predicting a treatment or prevention effect of treating or preventing B lymphocyte dysfunction-related diseases.
