Provided is a chimeric antigen receptor (CAR) specifically binding to CD138, an immune cell expressing same, and a pharmaceutical composition for the treatment or prevention of cancer including same as an active ingredient. It was confirmed that the CD138 chimeric antigen receptor (CAR)-expressing immune cell of the presently claimed subject matter efficiently exhibits strong cytotoxic ability against CD138-expressing (positive) cancer cells. Accordingly, it is expected that the CD138 chimeric antigen receptor (CAR)-expressing immune cell of the presently claimed subject matter can be utilized for the treatment of CD138-expressing (benign) cancer diseases.

A chimeric antigen receptor that specifically binds to a CD300c antigen or a receptor thereof, immune cells expressing the same, and uses thereof are disclosed. The chimeric antigen receptor that specifically binds to a CD300c antigen or a receptor thereof is able to specifically recognize cancer cells expressing the CD300c antigen or the CD300c receptor so that growth, metastasis, development, and the like of cancer can be suppressed in a direct and effective manner. Thus, it is expected that the chimeric antigen receptor can be effectively used as an immunotherapeutic agent for various cancers.

Provided herein are D domain containing polypeptides that specifically bind targets of interest, as are nucleic acids encoding the D domain containing polypeptides, vectors containing the nucleic acids and host cells containing the nucleic acids and vectors. Also provided herein are methods of making and using the D domain containing polypeptides, nucleic acids, vectors and host cells, for example, but not limitefd to, in diagnostic and therapeutic applications. Also provided herein are multi-functional chimeric antigen receptor (CAR)-based compositions and Adapters and their use in methods of directing immune responses to target cells. In some embodiments, the methods include the use of a CAR expressing cell in combination with an Adapter. The Adapter confers the ability to modulate, alter, and/or direct CAR expressing cell-mediated immune response in vitro and in vivo.

Provided for herein are fusogenic rhabdovirus glycoproteins and uses thereof, compositions comprising the same, and methods of using the same. Also provided for herein are pseudotyped viral particles comprising rhabdovirus glycoproteins as provided for herein and targeting moieties as provided for herein. Also provided are methods of generating and using the pseudotyped viral particles as provided for herein.

The present invention provides a pharmaceutical composition comprising cells expressing a chimeric receptor, for use in combination with administration of an antigen-binding molecule, wherein the chimeric receptor comprises an extracellular domain, the extracellular domain comprises an extracellular domain of an immunoreceptor, an extracellular domain variant of an immunoreceptor, or a portion thereof, and the antigen-binding molecule is a multispecific antigen-binding molecule having a target antigen recognition site and an immunoreceptor recognition site which recognizes the immunoreceptor.

The disclosure relates to an anti-CD133 single-chain antibody. The amino acid sequence of the anti-CD133 single-chain antibody comprises a sequence shown in SEQ ID NO. 1. T lymphocytes expressing the anti-CD133 single-chain antibody can specifically kill CD133-positive tumor cells and have higher specificity and stronger killing ability.

Provided are a method for engineering T-cells or pluripotent stem cells, as well as engineered T-cells and pluripotent stem cells. The method specifically comprises: engineering the T cells or pluripotent stem cells to obtain engineered T cell or engineered pluripotent stem cells with reduced expression, activity, and/or signaling of NKG2A. The obtained engineered T cell and a composition containing the engineered T cell can be used to treat diseases, such as cancer (tumor) and autoimmune diseases.

The disclosure relates to an anti-TIM3 single-chain antibody. The amino acid sequence of the anti-TIM3 single-chain antibody is a sequence shown in SEQ ID NO. 1. T lymphocytes expressing the anti-TIM3 single-chain antibody can effectively kill tumor cells.

The present invention provides methods for preselecting TILs based on PD-1, CD39, CD38, CD103, CD101, LAG3, TIM3 and/or TIGIT expression, as well as methods for expanding those preselected PD-1, CD39, CD38, CD103, CD101, LAG3, TIM3 and/or TIGIT positive TILs in order to produce therapeutic populations of TILs with enhanced tumor-specific killing capacity (e.g., enhanced cytotoxicity).

Provided herein are gRNA comprising a targeting domain that targets CD6, which may be used, for example, to make modifications in cells. Also provided herein are methods of genetically engineered cell having a modification (e.g., insertion or deletion) in the CD6 gene and methods involving administering such genetically engineered cells to a subject, such as a subject having a hematopoietic malignancy.
