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.

Genetically engineered activated phagocytic cells are described and related vectors, compositions, methods and systems which allow efficient cell targeting through enhanced phagocytosis of target cells and treatment of conditions in an individual.

The present invention relates to a Leukocyte-specific protein 1 (LSP1)-deficient T cell-based anticancer immunotherapy. According to the present invention, tumor growth, tumor volume and size were reduced by means of LSP1 knockout, and LSP1 deficiency in T cells increases the number, distribution frequency, migration, and invasion of T cells, and increases the production of an anti-tumor cytokine to inhibit tumor growth and enhance tumor-killing ability. Thus, the present invention can be used for T cell-based immunotherapy.

The present disclosure provides novel cell compositions engineered to express at least a chimeric antigen receptor and a survival factor. Methods of using such cell compositions are also described.

A technique for enhancing functions such as proliferation ability and imparting an activity of capturing cytokines which may cause side effects in immune cells for use in the adoptive immunotherapy is disclosed. A chimeric cytokine receptor having a ligand-binding region with a cytokine-binding region of a cytokine receptor at the N-terminal side and a T-cell activating region having the transmembrane domain and the intracellular domain of an IL-7 receptor chain at the C-terminal side is provided. Amino acid sequence SEQ ID NO: 1 of the transmembrane domain has an insertion of one of: (a) amino acid sequence SEQ ID NO: 2 between positions 243 and 244, (b) amino acid sequence SEQ ID NO: 3 between positions 241 and 242, (c) amino acid sequence SEQ ID NO: 4 between positions 244 and 245, (d) amino acid sequence of SEQ ID NO: 5 between positions 244 and position 245, or (e) amino acid sequence of SEQ ID NO: 6 between positions 246 and 247.

Provided are methods, polynucleotides and compositions for the generation of engineered Treg cells. The methods, polynucleotides and compositions enable the reprogramming of hematopoietic cells into Treg cells by constitutive or regulated expression of FOXP3 in engineered cells such that the engineered Treg cells can suppress the activation and proliferation of responder T cells.

Provided are methods for activating an antigen-presenting cell and eliciting an immune response by inducing an inducible pattern recognition receptor adapter, or adapter fragment, and CD40 activity. Also provided are nucleic acid compositions comprising sequences coding for chimeric proteins that include an inducible CD40 peptide and an inducible pattern recognition receptor adapter or adapter fragment.

The present invention relates to compositions, methods, and kits for eliciting an immune response to at least one CMV antigen expressed by a cancer cell, in particular for treating and preventing cancer. CMV determination methods, compositions, and kits also are provided.

The present disclosure provides modified immune cells or precursors thereof (e.g. modified T cells) comprising a chimeric cell surface sialidase or a variant sialidase precursor protein. Compositions and methods of treatment are also provided.

A modified cell, a method for preparing a modified cell, and a use thereof in treatment of a disease. The modified cell comprises a polynucleotide that encodes a presenting peptide, wherein the polynucleotide is under the transcriptional regulation of an endogenous B2M gene.
