The present disclosure relates to a method of expanding myeloid progenitor cells by culturing an initial population of cells in a medium comprising a mixture of cytokines and growth factors that promote growth and expansion of the myeloid progenitor cells. The expanded cell population provides a source of cells as therapeutic treatments for neutropenia and/or thrombocytopenia arising in patients subjected to myeloablative therapy and hematopoietic stem cell transplantation.

The invention provides CARs (CARs) that specifically bind to BCMA (B-Cell Maturation Antigen). The invention further relates to engineered immune cells comprising such CARs, CAR-encoding nucleic acids, and methods of making such CARs, engineered immune cells, and nucleic acids. The invention further relates to therapeutic methods for use of these CARs and engineered immune cells for the treatment of a condition associated with malignant cells expressing BCMA (e.g., cancer).

We demonstrate herein that neuritin controls the homeostasis of regulatory T cells in an antigen dependent manner. Based on this discovery, we describe herein the application of neuritin as a therapeutic agent to manipulate antigen specific regulatory T cells in various disease settings is described. Thus manipulation of Treg cells and DCs through neuritin can be used to enhance immunotherapy of autoimmune diseases, cancer and infectious diseases, as well as enhance lymphocyte engraftment in settings of donor lymphocyte infusion, bone marrow transplant, as well as other types of transplants, and adoptive transfer.

Embodiments of the disclosure concern methods and compositions for delivering therapeutic, diagnostic or interventional moieties, such as complex and simple entities such as biologies, including at least cells, for example. The methods employ targeted delivery by employing at least one ALCAM-binding moiety on the therapeutic, diagnostic or interventional moiety to be delivered. In specific cases, the ALCAM-binding moiety is present on or with the therapeutic moiety in multiple iterations. In certain embodiments, the ALCAM-binding moiety comprises at least one SRCR domain from CD6 and a stalk, such as from CD6, of the secretable or molecular form thereof.

The present invention relates to alternatively activated macrophages (AAMs) for use in the treatment of liver injury and methods of treating and preventing liver injury using AAMs.

The present invention provides Claudin-6-specific immunoreceptors (T cell receptors and artificial T cell receptors (chimeric antigen receptors; CARs)) and T cell epitopes which are useful for immunotherapy.

The present disclosure provides novel co-stimulatory domains useful in genetically-modified cells to promote cell proliferation and/or promote cytokine secretion after antigen recognition. For example, disclosed herein are genetically-modified cells comprising a chimeric antigen receptor or an inducible regulatory construct incorporating the co-stimulatory domains disclosed herein. Also disclosed herein are plasmids and viral vectors comprising a nucleic acid sequence encoding the co-stimulatory domains, and methods of administering compositions comprising the novel co-stimulatory domains to subjects in order to reduce the symptoms, progression, or occurrence of disease, such as cancer.

Methods of reducing or reversing chronic graft-versus-host-disease (cGVHD) are provided herein.

Provided in the present invention is an antibody for anti-claudin 18A2 and an immune effector cell targeting claudin 18A2. Also provided are methods for inducing cell death and treating tumours.

Chimeric antigen receptors for efficient and selective in vitro proliferation and uses thereof. Specifically, the present invention provides a CAR-encoding molecule with specific selectivity in vitro. By introducing a humanized selective domain into the molecule, the CAR-positive cells after being infected can be efficiently sorted via a secondary sorting step. Upon exposure to the selective domain-specific antibody, the CAR-transduced immune cells can be selectively expanded; therefore, the ratio of the CAR-positive target cells in the final product is significantly increased, improving the efficiency of preparing CAR gene-modified immune cell products. The present invention provides a more reliable technical support for further promotion and application of such products in clinical practice.
