Provided is application of chimeric antigen receptor (CAR)-modified T (CART) cells in preparing drugs for cancer treatment, the CART cells contain an artificially-introduced costimulatory signal transduction domain, and the CART cell does not contain an artificially-introduced first signal transduction domain.

The present invention provides a system for providing a T cell product, including a T cell master cell bank and/or a T cell working cell bank.

An object of the present invention is to provide clinically applicable aAVC-NY-ESO-1 cells stably expressing NY-ESO-1 in order to use aAVC-NY-ESO-1 cells in treating patients having a NY-ESO-1-expressing cancer. The present invention provides, for example, a human-derived cell comprising a polynucleotide encoding CD1d and a polynucleotide encoding NY-ESO-1 or a fragment thereof, wherein the polynucleotide encoding NY-ESO-1 or a fragment thereof is operably linked to an inducible promoter.

An object of the present invention is to provide an evaluation system capable of detecting an extracellular purinergic receptor ligand minimally invasively, chronologically and systemically, and the present invention provides a genetically modified non-human animal expressing a first fusion protein and a second fusion protein for detecting an extracellular purinergic receptor ligand, in which the first fusion protein comprises a membrane protein that binds to a purinergic receptor ligand, and a first reporter protein, and the second fusion protein comprises a protein that binds to the membrane protein bound to the ligand, and a second reporter protein; and a cell thereof.

Provided is an obsessive-compulsive disorder animal model and a production method thereof, in which a neuronal circuit connecting the basolateral amygdala (BLA) and the dorsomedial striatum (DMS) is activated. In the present disclosure, it was confirmed that the BLA and DMS are connected to each other, and that when the BLA-DMS neuronal circuit is activated, there is a large increase in checking, repeating, cleaning, and collecting, which are compulsive behaviors representative of obsessive-compulsive disorder, and a decrease in cognitive flexibility. Therefore, animals in which the BLA-DMS neuronal circuit is activated may be useful as animal models for studying obsessive-compulsive disorder. In particular, the obsessive-compulsive disorder animal model can reproduce all of the compulsive behaviors and thus may become the first animal model to provide an understanding of the interactions between anxiety behaviors and compulsive behaviors, which existing animal models have not been able to provide.

Disclosed herein are anti-mesothelin antibodies and antigen-binding fragments, chimeric antigen receptors (“CARs”) having these anti-mesothelin antibodies and antigen-binding fragments (“mesothelin CARs”) and genetically modified immune effector cells having such mesothelin CARs. Polynucleotides encoding the anti-mesothelin antibodies and antigen-binding fragments and mesothelin CARs are also provided herein. Compositions comprising anti-mesothelin antibodies and antigen-binding fragments and mesothelin CARs are also provided herein. The present disclosure also relates to uses of the anti-mesothelin antibodies and antigen-binding fragments and genetically modified immune effector cells having such mesothelin CARs in cancer treatment.

The present invention relates to a chimeric costimulatory antigen receptor (CoStAR) useful in adoptive cell therapy (ACT), and cells comprising the CoStAR. The CoStAR can act as a modulator of cellular activity enhancing responses to defined antigens. The present invention also provides CoStAR proteins, nucleic acids encoding the CoStAR and therapeutic uses thereof.

The invention provides bispecific fusion proteins that inhibit activation of complement pathway and vascular endothelial growth factor (VEGF) pathway and methods for using these fusion proteins.

The present invention is situated in the field of multimers used for targeted therapies. More particularly, the invention relates to methods for preparing multifunctional heteromultimeric protein complexes with a defined ratio of functional components and to multifunctional heteromultimeric protein complexes for directing complement-dependent cytolysis, optionally comprising a scaffold, which display three or more different functional components present in a defined relative ratio, of which one is a tracking component.
