Chimeric Antigen Receptors (CARs) comprising a costimulatory sequence which is, or which is derived from, the intracellular domain of CD226, or a fragment thereof, are disclosed. Also disclosed are compositions comprising such CARs, and uses and methods using the same.

This disclosure relates to compositions and methods for treating cancer using armored chimeric antigen receptor cells.

The invention relates to the field of biomedicine, in particular to a T cell co-expressing CXCR2 and a Synthetic T-Cell Receptor and Antigen Receptor (STAR) against GPC3, and uses thereof.

Compositions and methods are provided for the treatment of cancer. An immune effector cell population is pre-infected with an oncolytic virus. The combined therapeutic is safe and highly effective, producing an enhanced anti-tumor effect compared to either therapy alone. The methods of the invention thus provide for a synergistic effect based on the combined biotherapeutics.

This disclosure provides bispecific antibody molecules that specifically bind to NKp46 and Glypican 3 (GPC3). The disclosure further relates to combination therapies comprising the bispecific antibody molecules. The bispecific antibody molecules can be used to treat, prevent and/or diagnose cancer or infectious conditions or disorders associated with cells expressing NKp46 and/or GPC3.

The invention involves generating a T cell response to subdominant antigens and using the cells to therapeutically change the cellular homeostasis and nature of the immune response. In a preferred embodiment, the cells are generated outside of the patient avoiding the influence of the patient's immunologic milieu. By stimulating and growing the T cells from a patient in a tissue culture to one or more subdominant antigens and the transplanting them into the patient, if enough cells are expanded and transplanted, the transplanted cells overwhelm the endogenous dominant T cells in the response to either break or induce immune tolerance or otherwise modify the immune response to the cells or organism expressing that antigen. When the memory cells are established they are then reflective of this new immunodominance hierarchy so that the desired therapeutic effect is long lasting. In effect, the transplantation exogenously generated T cells reactive to the subdominant antigens is recapitulating priming and rebalancing the patient's immune response to target previously subdominant antigens in the cells or organism to produce a therapeutic benefit.

Disclosed is a method for promoting immune cell proliferation. The method comprises the following step: upregulating the expression of low-density lipoprotein receptor-related proteins or fragments thereof in immune cells.

An immune effector cell expressing a chimeric cytokine receptor comprising a first extracellular antigen binding domain, a first transmembrane domain, and a cytokine receptor intracellular domain; and a functional exogenous receptor comprising a second extracellular antigen binding domain, a second transmembrane domain, and an intracellular signaling domain.

Disclosed herein are methods of treating a subject exhibiting a solid tumor that expresses Glypican-3 (GPC3). The methods typically utilize g GPC3 chimeric antigen receptor immunoresponsive cells to a subject in need thereof to effect killing of tumor cells.

The present disclosure provides compositions comprising mature dendritic cells loaded with autologous tumor cell lysates for the treatment of liver cancers, such as hepatocellular carcinoma. Hepatocellular carcinoma (HCC) is the fifth leading cancer and third leading cause of cancer-related mortality worldwide. Surgical resection and liver transplantation remain the mainstay of effective therapy for patients with early disease. However, a prevalent problem with HCC is the high likelihood of initial diagnosis at an advanced stage.
