A pharmaceutical includes helper T cells induced from pluripotent stem cells. The helper T cells include CD4-positive CD40L-highly expressing T cells, dendritic cells, antigen, and cytotoxic T cells CD8-positive T cells. The pharmaceutical can be administered in a method for treating cancer to a patient having cancer cells expressing an antigen specifically recognized by CD4-positive T cells.

The present invention relates to the field of manufacturing of Natural Killer (NK) Cells genetically modified with viral vectors carrying a polynucleotide coding for a Chimeric Antigen Receptors (CARs). The present invention further relates to CAR-NK cells obtained with the method and use of the CAR-NK cells in medicine, in particular for use in a method of treating cancer.

The disclosure provides modified NK cells and pharmaceutical compositions comrpsing the same. The disclosure also provides methods of treating cancer using the same.

Embodiments of the disclosure includes methods of producing viral-specific therapy (VST) cells specific for the SARS-CoV-2 virus and uses of the cells. The methods may utilized peptide mixtures and stimulation of mononuclear cells using particular cytokine cocktails. The cells may also be genetically modified to lack expression of one or more endogenous genes, including one or more genes that renders the cells more effective and/or able to withstand deleterious conditions, such as the presence of glucocorticoids.

The present disclosure relates to expansion and activation of T cells. In an aspect, the present disclosure relates to expansion and activation of γδ T cells that may be used for transgene expression. In another aspect, the disclosure relates to expansion and activation of γδ T cells while depleting α- and/or β-TCR positive cells. T cell populations comprising expanded γδ T cell and depleted or reduced α- and/or β-TCR positive cells are also provided for by the instant disclosure. The disclosure further provides for methods of using the disclosed T cell populations.

This invention relates to Natural Killer (NK) cell populations, to methods of producing the same and therapeutic applications thereof. More specifically, the invention relates to the expansion of NK cells by increasing the expression of specific transcription factors associated with NK cell production.

The present invention provides improved and/or shortened methods for expanding TILs and producing therapeutic populations of TILs, including novel methods for expanding TIL populations in a closed system that lead to improved efficacy, improved phenotype, and increased metabolic health of the TILs in a shorter time period, while allowing for reduced microbial contamination as well as decreased costs. The methods may comprise gene-editing at least a portion of the TILs to enhance their therapeutic efficacy. Such TILs find use in therapeutic treatment regimens.

Provided is a non-naturally occurring T population, of which the proportion of T memory stem cells satisfies C1≥50%. The T cell population comprises a tumor antigen-targeting universal CAR-T cell. Further provided is a method for preparing the CAR-T cell. The CAR-T cell is higher in amplification rate and better in phenotype, IFN-gamma releasing capacity and target cell killing capability.

Provided herein are methods and compositions for dynamically controlling and targeting multiple immunosuppressive mechanisms in cancer. Some aspects provide cells engineered to produce multiple effector molecules, each of which modulates a different immunosuppressive mechanisms of a tumor, as well as methods of using the cells to treat cancer, such as ovarian, breast, or colon cancer.

The invention relates to: a composition for culturing natural killer cells, comprising, as an active ingredient, a fusion protein comprising an IL-2 protein and a CD80 protein; and a method for preparing natural killer cells by using same. Particularly, a composition for culturing natural killer cells, comprising, as an active ingredient, a fusion protein comprising IL-2 or a variant thereof and CD80 or a fragment thereof, of the present invention; promotes the proliferation of natural killer cells, induces the expression of CD16 and NKp46, and increases the expression and secretion of granzyme B and perforin, thereby being effectively usable in the preparation of natural killer cells having an excellent anticancer immune function.
