Provided in the present invention are a composition of immune effector cells and a treatment kit including the composition of immune effector cells, wherein the composition of immune effector cells comprises an initial dose of immune effector cells and a subsequent dose of immune effector cells.

A population of genetically engineered T cells, comprising a disrupted Reg1 gene and/or a disrupted TGFBRII gene. Such genetically engineered T cells may comprise further genetic modifications, for example, a disrupted CD70 gene. The population of genetically engineered T cells exhibit one or more of (a) improved cell growth activity; (b) enhanced persistence; and (c) reduced T cell exhaustion, (d) enhanced cytotoxicity activity, (e) resistant to inhibitory effects induced by TGF-b, and (f) resistant to inhibitory effects by fibroblasts and/or inhibitory factors secreted thereby, as compared to non-engineered T cell counterparts.

The present disclosure provides methods for expanding TIL populations from fine needle aspirates (FN As) or small biopsies which contain low numbers of TILs, using the methods disclosed herein including in a closed system that leads to improved phenotype and increased metabolic health of the TILs in a shorter time period.

The present invention relates to a chimeric antigen receptor having a ligand specifically targeting an anthrax toxin receptor (ANTXR), and, more specifically, to: a nucleic acid encoding a chimeric antigen receptor comprising ligand PA63 specifically binding to anthrax toxin receptor 1 (ANTXR1) or anthrax toxin receptor 2 (ANTXR2); a vector comprising the nucleic acid encoding a chimeric antigen receptor; and a recombinant cell comprising the vector; a pharmaceutical composition for preventing or treating solid cancer, comprising the recombinant cell; and a treatment method. Solid cancer can be treated using an anti-ANTXR chimeric antigen receptor (CAR)-T cell, according to the present invention, and since the chimeric antigen receptor (CAR)-T cell is administered to patients with solid cancer for whom anti-cancer drug administration is not effective, especially patients with pancreatic cancer, drug administration is limited, and customized solid cancer prevention or treatment, which are efficient and safe, is possible.

The present application provides compositions and methods for producing antigen presenting cells (APCs) from monocytes (e.g., monocytes from cancer patients) that involve an IL-10 receptor activator (e.g., IL-10), IFN receptor activator (e.g., IFN), TNF receptor activator (e.g., TNF), IL-4 receptor activator (e.g., IL-4), GM-CSF receptor activator (e.g., GM-CSF), and/or IL-6 receptor activator (e.g., IL-6). APCs produced accordingly are also provided, as well as methods of activating immune cells (e.g., T cells) via co-culturing with APCs. The activated immune cell compositions and the methods of treatments that involve the activated immune cells are also provided.

The invention provides compositions and methods for treating diseases such as cancer. The invention also relates to a method of administering a therapy comprising a chimeric antigen receptor, an IL-15R molecule and an IL-15 molecule.

The present disclosure provides gene edited modified immune cells or precursors thereof (e.g., gene edited modified T cells) comprising an exogenous T cell receptor (TCR) and/or a chimeric antigen receptor (CAR) having specificity for a target antigen, and an insertion and/or deletion in one or more endogenous gene loci, wherein the endogenous gene loci encode regulators of T cell function, thereby resulting in immune cells having enhanced function. Compositions and methods of treatment are also provided. The present invention provides methods of screening for TCR- or CAR-T cells with enhanced immune function (e.g., T cell efficacy, T cell memory, and/or T cell persistence).

The present invention relates to an in vitro culture of haematopoietic cells, wherein said haematopoietic cells differentiate to form granulocytes characterised by the ability to kill cancer cells. The invention also relates to said granulocytes, methods for identifying said haematopoietic cells and granulocytes, compositions and kits comprising the same, as well as uses of the same for treating cancer.

Methods of expanding tumor infiltrating lymphocytes (TILs) using a tumor necrosis factor receptor superfamily (TNFRSF) agonist, such as a 4-1BB agonist, a CD27 agonist, a glucocorticoid-induced TNF receptor-related agonist, an OX40 agonist, a HVEM agonist, or a CD95 agonist, and uses of such expanded TILs in the treatment of diseases such as cancer are disclosed herein. In addition, in some embodiments, therapeutic combinations of TILs and TNFRSF agonists useful in the treatment of diseases such as cancer, including compositions, uses, and dosing regimens thereof, are disclosed herein.

Disclosed is an isolated or purified T cell receptor (TCR) having antigenic specificity for an HLA-A11-restricted epitope of mutated Kirsten rat sarcoma viral oncogene homolog (KRAS) (KRAS.sub.7-16), Neuroblastoma RAS Viral (V-Ras) Oncogene Homolog (NRAS), or Harvey Rat Sarcoma Viral Oncogene Homolog (HRAS). Related polypeptides and proteins, as well as related nucleic acids, recombinant expression vectors, host cells, populations of cells, and pharmaceutical compositions are also provided. Also disclosed are methods of detecting the presence of cancer in a mammal and methods of treating or preventing cancer in a mammal.
