The present invention relates to an expanded population of human Breg cells having the phenotype CD19+CD73CD71+CD25+TIM-1+ and methods for producing the cell population of the invention. The invention also relates to pharmaceutical compositions comprising the cell populations of the invention and their use in the treatment of immune-mediated disorders.

The present invention relates to an isolated cellular targeted delivery system comprising a CD45.sup.+ leukocyte cell comprising within said cell a complex of one or more iron binding proteins and an active ingredient as well as methods for producing such isolated cellular targeted delivery system and uses of such system for therapy, in particular for therapy of cancer.

The present invention relates to an isolated cellular targeted delivery system comprising a CD45+ leukocyte cell comprising within said cell a complex of one or more iron binding proteins and/or a label as well as methods for producing such isolated cellular targeted delivery system and uses of such system for therapy diagnosis and in particular for diagnosis of cancer, particularly metastatic cancer, in particular for therapy of cancer.

The present application relates to plasma cells and plasma cell precursors that express a macromolecule, such as a protein, protein mimetic or a peptide and compositions comprising these plasma cells or plasma cell precursors. The application further relates to methods of using and making the plasma cells and plasma cell precursors that express the macromolecule. Methods of treatment comprising administering the plasma cells or plasma cell precursors are also contemplated.

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 present invention relates to a method for in vitro cultivation of hematopoietic and/or mesenchymal cells, wherein said cells are cultivated in a cultivation medium comprising gamma-aminobutyric acid (GABA) or a GABA receptor agonist, to cells obtained by such a method and therapeutic use of such cells in methods of treatment of autoimmune, inflammatory or allergic disorder. The invention further relates to pharmaceutical compositions comprising the cells and cultivation media for use in the method according to the invention.

Provided are feeder cell lines that can be used to expand and differentiate B cells in vitro, a method for expanding B cells in vitro comprising culturing the B cells with the feeder cell line, and a method for producing monoclonal antibody in vitro comprising culturing a single B cell with the feeder cell line under sufficient conditions and for sufficient time to induce expansion and differentiation of the B cell into a B cell done secreting antibody.

Provided herein are methods for manufacturing, expanding, and/or generating genetically modified T cells comprising a chimeric antigen receptor (CAR) or T-cell receptor (TCR).

Herein is reported a method for the co-cultivation of single deposited B-cells, which can be of any source, with EL-4 B5 feeder cells in a suitable co-cultivation medium. In the herein reported methods the EL-4 B5 cells have been irradiated with a dose of less than 40 Gy, preferably 9.5 Gy or less. Thereby the EL-4 B5 cells have a higher viability and maintain the ability to divide in cultivation at doses less than 6 Gy.

The present invention relates to an isolated cellular targeted delivery system comprising a CD45+ leukocyte cell comprising within said cell a complex of one or more iron binding proteins and an active pharmaceutically active substance and/or label as well as methods for producing such isolated cellular targeted delivery system and uses of such system for prophylaxis, therapy, diagnosis or theragnosis, in particular for prophylactic or therapeutic vaccination, therapy of cancer, particularly metastatic cancer or inflammatory diseases.
