The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

This disclosure relates to chimeric antigen receptors targeting T cell malignancies. The present disclosure also relates to the development of methods for inactivation with engineered CARs, to enhance T cell functions or reduce T cell suppression.

The present disclosure relates to chimeric Tim4 receptors, host cells modified to include chimeric Tim4 receptor molecules, and methods of making and using such receptor molecules and modified cells.

Provided herein are methods employing various fusion constructs in T cell therapy. The fusion constructs allow for one to reduce, to the point of full removal if desired, the use of IL-2 that would otherwise accompany an in vivo T cell therapy.

Provided are engineered cells (such as stem cells or T cells) that have a surface molecule comprising a membrane-tethered binding moiety that binds to a T cell surface antigen (such as CCR5, CD4 or CXCR4) or a HIV antigen, or a membrane tethered inhibitory moiety that inhibits the membrane fusion of HIV (such as C34). Also provided are methods of making and using these engineered cells.

The present disclosure provides a chimeric antigen receptor (CAR) for activating dendritic cells (DCs) in an immunosuppressive tumor environment. The present disclosure also provides compositions comprising the CAR, polynucleotides encoding the CAR, vectors comprising a polynucleotide encoding the CAR, engineered cells comprising the CAR, and method using the same.

This invention provides, as a therapeutic method for eradication of neoplastic diseases of the blood with poor diagnosis, a cell co-expressing a chimeric antigen receptor (CAR) protein and a CXCL12 receptor protein on the cell membrane, and an agent and a pharmaceutical composition having anti-tumor activity, which comprises such cell.

The present disclosure provides chimeric antigen receptor polypeptides having antigen recognition domains for CD2, CD3, CD4, CD5, CD7, CD8, and CD52 antigens, and polynucleotides encoding for the same. The present disclosure also provides for engineered cells expressing the polynucleotide or polypeptides. In some embodiments, the disclosure provides methods for treating diseases associated with CD2, CD3, CD4, CD5, CD7, CD8, and CD52 antigens.

The present invention relates to chimeric immune receptor molecules for reducing or eliminating tumors. The chimeric receptors are composed a C-type lectin-like natural killer cell receptor, or a protein associated therewith, fused to an immune signaling receptor containing an immunoreceptor tyrosine-based activation motif. Methods for using the chimeric receptors are further provided.

Implantable scaffolds that treat solid tumors and escape variants and that provide effective vaccinations against cancer recurrence are described. The scaffolds include genetically-reprogrammed lymphocytes and a lymphocyte activating moiety.
