A humanized CD 19 antibody, and a chimeric antigen receptor thereof, an immune cell thereof and the use thereof are provided. The humanized CD19 antibody is based on a FMC63 chimeric antibody, which is subjected to humanization modification. A CAR-T and a dual CAR-T cell constructed based on the humanized antibody and the related use thereof are also provided. Compared with a CAR-T cell constructed by using FMC63, the CAR-T cell constructed based on the humanized antibody has higher killing effect and tumor removal ability.

The present application is directed to a method of inhibiting proliferation of chromosome instable cancer cells. This method involves administering, to a population of cancer cells comprising chromosome instable cancer cells, an inhibitor of Kinesin Family Member 18A (KIF18A) at a dosage effective to inhibit proliferation of said chromosome instable cancer cells. The inhibitors of KIF18A may also be used in a method treating cancer in a subject. This method involves selecting a subject having cancer, where the cancer is characterized by chromosomal instability, and administering to the subject an inhibitor of KIF18A at a dosage effective to treat the cancer in the subject. Also disclosed is a combination therapeutic including an inhibitor of Kinesin Family Member 18A (KIF18A) and agent that promotes microtubule turnover or a cyclin-dependent kinase (CDK) inhibitor.

Embodiments of the disclosure include methods and compositions related to treating an individual for HER2+ positive cancer with an appropriate treatment based on outcome of a multiparameter classifier. The methods allow for identification of HER2+ individuals that are suitable to avoid chemotherapy, in specific embodiments. Methods of the disclosure also allow for identification of HER2+ individuals that should not avoid chemotherapy. In specific embodiments, the multiparameter classifier identifies whether there is (1) a ratio of HER2 amplification, relative to a control probe, of greater than or equal to 4.5; (2) a HER2 expression level score of 3+, as determined by immunohistochemistry, in at least 90% of breast cancer cells; (3) whether there is a HER2-enriched molecular subtype; and (4) whether the individual has a wildtype PIKC3A gene.

Endometriosis is a chronic inflammatory systemic sex hormone-dependent gynecological disease, characterized by the presence and growth of endometrial tissue (glands and stroma) outside the uterine cavity, predominantly, but not exclusively, in the pelvic compartment. Here, the inventors show that the use of Neuropilin/VEGF binding inhibitors, so called, Neuropilin antagonist (NRPa), bring new perspective to treat and cure endometriosis in women suffering thereof. NRPa alone is efficient to inhibit primary endometrial cell proliferation and apoptosis/necrosis program cell death of targeted cells. The effective NRPa concentration needed is very low (NRPa-48 IC.sub.50=10.sup.−7M) and is dependent of the NRPa structure. Moreover, the association of NRPa with progestogen drug increases the anti-proliferative effect. Therefore, the present invention relates to the use of neuropilin antagonists for the treatment of endometriosis.

The present disclosure provides monoclonal antibodies that selectively bind to pathological tau over native tau. In certain aspects, the antibodies inhibit or minimize propagation of tau aggregates and/or reduce spread of pathological tau in vivo. In other aspects, the disclosure comprises a method of treating, ameliorating, and/or preventing a tauopathy in a subject, comprising administering any one of the antibodies of the disclosure to the subject. In yet other aspects, the disclosure comprises methods of detecting pathological tau using any one of the antibodies of the disclosure.

The present disclosure relates to recombinant human adenoviruses engineered to express a structural protein of a coronavirus. The recombinant adenoviruses are suitable for active immunization against a coronavirus in a human subject. Additionally, immune globulin obtained from immunized human subjects is suitable for passive immunization of a coronavirus-infected human subject.

The present invention discloses immunogenic compositions including recombinant peptides and proteins comprising human immunodeficiency viruses (HIV) antigens and immunogens, e.g., gp 120 protein peptides. In some aspects, the immunogenic composition comprises a secreted fusion protein comprising a soluble HIV viral antigen joined by in-frame fusion to a C-terminal portion of a collagen which is capable of self-trimerization to form a disulfide bond-linked trimeric fusion protein. In some aspects, the immunogenic compositions provided herein are useful for generating an immune response, e.g., for treating or preventing an HIV infection. In some aspects, the immunogenic compositions provided herein may be used in a vaccine composition, e.g., as part of a prophylactic and/or therapeutic vaccine. Also provided herein are methods for producing the recombinant peptides and proteins, prophylactic, therapeutic, and/or diagnostic methods, and related kits.

The present application provides antibodies including antigen-binding fragment thereof that specifically recognizing Granulocyte-Macrophage Colony Stimulating Factor Receptor (GM-CSFRα). Also provided are methods of making and using these antibodies.

The invention provides antibodies that specifically bind sortilin. The antibodies inhibit or delay pathologies associated with changes in progranulin levels and associated symptomatic deterioration.

The present invention provides broadly neutralizing antibodies against HIV, compositions comprising the same and methods of use thereof.
