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. Such TILs find use in therapeutic treatment regimens.

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.

Disclosed are means, compositions of matter and protocols useful for treatment of neurological dysfunctions through stimulation of adult neurogenesis using administration of umbilical cord derived mesenchymal stem cells such as JadiCells. In one embodiment viral induced neuropathy is reduced by administration of JadiCells to stimulate neurogenesis. In another embodiment the neurogenic activity of selective serotonin reuptake inhibitors is enhanced by administration of JadiCells. In some embodiments administration of JadiCell exosomes, conditioned media, microvesicles and/or apoptotic bodies is utilized to stimulate neurogenesis.

The present disclosure relates to genetically modified B cells, including memory cells, differentiated to plasmablasts or plasma cells useful for long tem in vivo expression of a transgene, such as a specific antibody or other protein therapeutic. Also disclosed are methods of producing the cells and methods of treatment.

The present invention relates to the use of immunoregulatory macrophages for treating diseases that are associated with pathological changes of the blood vessels. The present invention particularly relates to the use of immunoregulatory macrophages for treating micro- and macroangiopathies of the lower limbs. The invention furthermore relates to the use of immunoregulatory macrophages for promoting tissue remodelling to facilitate wound healing. Pharmaceutical compositions for use in the recited treatments are also disclosed which comprise the immunoregulatory macrophages.

The present invention is directed to compositions and methods to increase the expression of PD-L1 and/or IDO-1 in a population of cells, the modulated cells expressing increased PD-L1 and/or IDO-1, and methods related to the immunosuppressive effects obtained by cells expressing increased PD-L1 and/or IDO-1.

The present disclosure pertains to methods of modifying an immune cell by delivering a modified messenger RNA (mRNA) encoding a chimeric antigen receptor (CAR) and modified immune cells comprising CARs.

Provided herein are carrier cells and virus combinations and methods for treatment of cancers. Also provided are modified carrier cells for such treatment, and methods of selecting carrier cells that are matched to subjects for such treatment.

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.

The improved 4-5 day, optionally 3-5 day GMP-compliant in-vitro method enables the production of macrophages from monocytes that benefits from a shorter cell culture time, fewer interventions whilst maintaining the desired characteristics of the human macrophages. The present invention describes a method wherein the monocytes are cultured in medium comprising one or more growth actors to stimulate macrophages with a pro-regenerative phenotype. The method described herein is xeno-free, serum-free and GMP compliant. In addition, further disclosed are macrophages produced according to the present invention and the use of said macrophages in the treatment of liver diseases, such as liver cirrhosis.
