An in vitro microfluidic intestine on-chip is described herein that mimics the structure and at least one function of specific areas of the gastrointestinal system in vivo. In particular, a multicellular, layered, microfluidic intestinal cell culture, which is some embodiments is derived from patient's enteroids-derived cells, is described comprising L cells, allowing for interactions between L cells and gastrointestinal epithelial cells, endothelial cells and immune cells. This in vitro microfluidic system can be used for modeling inflammatory gastrointestinal autoimmune tissue, e.g., diabetes, obesity, intestinal insufficiency and other inflammatory gastrointestinal disorders. These multicellular-layered microfluidic intestine on-chips further allow for comparisons between types of gastrointestinal tissues, e.g., small intestinal duodenum, small intestinal jejunum, small intestinal ileum, large intestinal colon, etc., and between disease states of gastrointestinal tissue, i.e. healthy, pre-disease and diseased areas. Additionally, these microfluidic gut-on-chips allow identification of cells and cellular derived factors driving disease states and drug testing for reducing inflammation.

Described herein are compositions and methods for treating a disease, particularly a cancer, with primed dendritic cells recognizing a tumor antigen. The methods may comprise storing, shipping and/or culturing dendritic cells, where the dendritic cells are stored on a hard surface. Lysis protocols are described where the lysis does not result in complete lysis of cells in order to provide cell surface molecules maintained in a cell surface-embedded state. Non-lethal Dengue virus strains are also provided for therapeutic purposes.

The present disclosure describes a pharmaceutical composition comprising a pharmaceutically acceptable carrier and a cell product comprising an expanded and enriched population of superactivated cytokine killer T cells, and methods for manufacturing the cell product.

There is described herein a method for inducing Tc22 lineage T cells from a population of CD8+ T cells, the method comprising: a) providing a population of CD8+ T cells; b) activating the population of CD8+ T cells; and c) culturing or contacting the population of CD8+ T cells with IL-6.

Disclosed herein are altered adherent stromal cells and methods of producing and utilizing same.

The present invention relates to compounds for use in treating a disease that is associated with (related to) CYP7B1 wherein the compound inhibits CYP7B1. The present invention further relates to a method of treating or preventing such a disease by administering an inhibitor of CYP7B1. The present invention also relates to a method of determining whether a compound is effective in treating or preventing a disease associated with the formation of inducible bronchus-associated lymphoid tissue (iBALT).

Provided herein are a composition and method for inducing differentiation into myeloid-derived suppressor cells from myeloid cells using glycyrrhizin, and an immunosuppressive composition including the composition or myeloid-derived suppressor cells induced by the method.

Provided herein are also a composition and method for inducing differentiation into CD11b+Gr1 myeloid cells using glycyrrhizin, and a composition for proliferating myeloid cells which includes glycyrrhizin.

Thus, glycyrrhizin of the present disclosure has an effect of inducing differentiation into CD11b+Gr1 myeloid cells or myeloid-derived suppressor cells from myeloid cells in vivo and in vitro, and thus is effective as a composition for inducing differentiation into CD11b+Gr1 myeloid cells or myeloid-derived suppressor cells, which includes the glycyrrhizin.

In addition, when myeloid cells are treated with lipopolysaccharide (LPS) before being treated with the glycyrrhizin of the present disclosure in vitro, the effect of inducing differentiation into CD11b+Gr1 myeloid cells or myeloid-derived suppressor cells from myeloid cells is further enhanced.

Disclosed is a method for rapidly amplifying CD8+ T cells and functional cell subpopulations thereof in vitro. A TLR1/2 agonist, a TLR2/6 agonist and a TLR5 agonist or a combination of above agonists is added to a conventional culture system for in-vitro amplification of CD8+ T cells. Recombinant cytokines IL-2, IL-7 and IL-15 as well as magnetic beads coated with an anti-human CD3 antibody and an anti-human CD28 antibody can be further added to the culture system for continuous co-stimulation.

Disclosed are methods of preparing an isolated population of dendritic cells, isolated populations of dendritic cells prepared by the methods, and pharmaceutical compositions comprising the isolated population of dendritic cells. Also disclosed are methods of treating or preventing cancer using the isolated population of dendritic cells or pharmaceutical compositions.

The present disclosure relates to compositions, nucleic acid constructs, methods and kits thereof for cell induction or reprogramming cells to the dendritic cell state or antigen presenting cell state, based, in part, on the surprisingly effect described herein of novel use and combinations of transcription factors that permit induction or reprogramming of differentiated or undifferentiated cells into dendritic cells or antigen presenting cells. Such compositions, nucleic acid constructs, methods and kits can be used for inducing dendritic cells in vitro, ex vivo, or in vivo, and these induced dendritic cells or antigen presenting cells can be used for immunotherapy applications.
