The present invention discloses an in-vitro culture, induction, activation and cryopreservation method and cell bank establishment for immune cells. The method includes the follows: using a dedicated amplification medium of immune cells to perform first-stage amplification culture on mononuclear cells to obtain preliminarily amplified immune cells; using a dedicated induction medium of immune cells to perform second-stage induction and amplification culture on the preliminarily amplified immune cells to obtain induced immune cells; using a dedicated activation medium of immune cells to perform third-stage activation and amplification culture on the induced immune cells to obtain a large number of immune cells with activation functions; using a dedicated cryopreserving fluid of immune cells to cryopreserve the immune cells to obtain cryopreserved immune cells; and performing preservation according to ABO/RH typing and HLA typing; and establishing an information file of immune cells for retrieval to construct an immune cell bank.

The present invention relates to a composition, comprising: IL-1β and vitamin B6; or IL-1β, vitamin B6, and IFN-α, for promoting immunomodulatory activity and inflammation-modulating ability of stem cells, and a method for preparing stem cells having improved immunomodulatory activity and inflammation-modulating ability by using same. When treated with IL-1β and vitamin B6; or IL-1β, vitamin B6, and IFN-α according to the present invention, stem cells are induced to increase IFN-γ inhibition, inducible costimulatory ligand (ICOSL) expression, indoleamine 2,3-dioxygenase (IDO) expression, and Galectin 1 expression, and thus can find various applications in a variety of immune disease treatment fields using stem cells.

Chimeric antigen receptors containing CD123 antigen binding domains are disclosed. Nucleic acids, recombinant expression vectors, host cells, antigen binding fragments, and pharmaceutical compositions, relating to the chimeric antigen receptors are also disclosed. Methods of treating or preventing cancer in a subject, and methods of making chimeric antigen receptor T cells are also disclosed.

The invention relates to methods for the isolation of non-haematopoietic tissue-resident lymphocytes, particularly γδ T cells. Such γδ T cells include non-Vδ2 cells, e.g. Vδ1, Vδ3 and Vδ5 cells and such non-haematopoietic tissues include skin and gut. It will be appreciated that such isolated non-haematopoietic tissue-resident lymphocytes find great utility in adoptive T cell therapies, chimeric receptor therapies and the like. Also provided are methods for expanding isolated tissue-resident lymphocytes, particularly methods for isolating and expanding γδ T cells. The present invention also relates to both individual cells and populations of cells produced by the methods described herein.

Provided herein are compositions and methods for use in generating an immune response against a target peptide antigen. Also included, are methods for stabilizing, treating, and eliminating various diseases and conditions associated with target peptide expression.

A seed cell medium of a tumor-infiltrating lymphocyte and an application thereof. The medium contains a cell culture component, a cell factor, and an immune checkpoint antibody or an antigen-binding fragment thereof. The cell factor includes IL-2; an immune checkpoint includes PD-1, LAG-3, TIGIT, and/or CTLA-4; and the cell culture component is a serum medium or a serum-free medium. The seed cell medium accelerates a culture of a seed cell of the tumor-infiltrating lymphocyte and shortens the amplification time required by the tumor-infiltrating lymphocyte.

Embodiments of the disclosure encompass systems, methods, and compositions for producing exosomes from primed mesenchymal stem cells that are expanded in the presence of IFNγ, TNFα, IL-1β, and IL-17. The systems, methods, and compositions ay occur in an automated cell expansion system that allows for controllable parameters and from which cells and exosomes may be harvested at one or more times as part of a particular regimen. In specific embodiments, the exosomes may be provided to an individual in need thereof, including in some cases when the exosomes comprise one or more therapeutic agents.

The present invention is based, in part, on the discovery of anti-SIGLEC-9 composition (e.g., monoclonal antibodies and antigen-binding fragments thereof), that regulate myeloid cell inflammatory phenotypes, such as suppressive myeloid cells, monocytes, macrophages, neutrophils, and/or dendritic cells, including polarization, activation, and/or function, and methods of using such anti-SIGLEC-9 compositions for therapeutic, diagnostic, prognostic, and screening purposes.

The present disclosure provides systems for growing and, modeling lung cells in organoid cultures and methods of using same.

Embodiments of the disclosure concern methods and compositions for immunotherapy for human papillomavirus infection and diseases associated therewith. In specific embodiments, methods concern production of immune cells that target one or more antigens of HPV16 and/or HPV18, including methods with stimulation steps that employ IL-7 and IL-15, but not IL-6 and/or IL-12. Other specific embodiments utilize stimulations in the presence of certain cells, such as costimulatory cells and certain antigen presenting cells.
