11969463 · 2024-04-30 · ·

The present invention relates to a cancer-specific tumor antigen neoepitope represented by any one of SEQ ID NOs: 1 to 214, an antigen-presenting cell loaded with the neoepitope, and a method for activating T cells for cancer treatment using the antigen-presenting cell. An antigen-presenting cell, that is, a dendritic cell, loaded with a cancer-specific tumor antigen epitope provided in the present invention enables rapid and effective induction of differentiation and proliferation of cancer antigen-specific T cells, preferably memory T cells, and the memory T cells thus activated can treat a cancerous or neoplastic condition or prevent recurrence, progression, or metastasis of cancer while avoiding the defense mechanism of cancer cells.

Process for T cell expansion

An in vitro expansion process for rapid expansion of antigen specific T cells, such as allogeneic antigen specific T cells comprising the steps culturing in a gas permeable vessel a population of PBMCs (such as allogeneic PBMCs) in the presence of antigen, for example a peptide or peptide mix relevant to a target antigen(s), in the presence of an exogenous cytokine characterized in that the expansion to provide the desired population of T cells is 14 days or less, for example 9, 10, 11 or 12 days, such as 10 days. The disclosure also extends to T cell populations generated by and obtained from the method and the use of same in therapy.

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.

CELLULAR TARGETED PHARMACEUTICALLY ACTIVE SUBSTANCE OR LABEL DELIVERY SYSTEM

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.

Medium system and method for ex vivo expansion of NK cells

This invention relates to a medium system and a method for ex vivo expansion of natural killer (NK) cells. This invention directly cultures Ficoll-separated PBMC by using immobilized anti-CD137 and RetroNectin, and uses OK-432 as a biological effector under the co-existence of GM-CSF, IL-4, IL-2, IL-15, and IL-21 for ex vivo activation and proliferation of NK cells, creating an efficient method for ex vivo expansion of NK cells. The expression rate of NK cells CD3-CD16+/CD56+ prepared by the method is as high as 92.5% or more. After 14 days of culture, NK cells can be expanded 1000 to 2000 times and have strong in vitro cytotoxic activity.

CANCER-KILLING CELLS
20190314409 · 2019-10-17 ·

The present invention relates to an in vitro culture of haematopoietic cells, wherein said haematopoietic cells differentiate to form granulocytes characterised by the ability to kill cancer cells. The invention also relates to said granulocytes, methods for identifying said haematopoietic cells and granulocytes, compositions and kits comprising the same, as well as uses of the same for treating cancer.

Method for preparing antigen-specific cytotoxic T-cells by using activated B-cells and use thereof

Disclosed in the present application are: a method for preparing in vitro/ex vivo antigen-specific cytotoxic T-cells by using B cells treated with biological response modifier; and a use thereof. The cytotoxic T-cells prepared by the method of the present application can be used advantageously for treating infectious disease and cancer and the like.

Method for producing B cell population

It is an object of the present invention to provide a method for easily producing an antigen-specific B cell population comprising IgG-positive B cells specific to a specific antigen. The present invention provides a method for producing a B cell population, comprising culturing B cells, in which the expression of a Bach2 gene has been increased, in the presence of a means for acting on CD40 and/or a BAFF receptor.

METHODS AND REAGENTS FOR MODULATING MACROPHAGE PHENOTYPE
20190290688 · 2019-09-26 ·

The present invention is directed to methods of inducing a phenotypic change in a population of monocytes and/or macrophages. The method includes administering to the population of monocytes and/or macrophages, a macrophage stimulating agent coupled to a carrier molecule, wherein the carrier molecule facilitates macropinocytic uptake of the agent by monocytes and macrophages in the population and is defective in neonatal Fc receptor binding, wherein the administering induces a phenotypic change in the monocytes and macrophages in the population.

Remnant Tumor Infiltrating Lymphocytes and Methods of Preparing and Using the Same

In some embodiments, methods of delivering a therapeutically effective amount of an expanded number of tumor infiltrating lymphocytes obtained from tumor remnants to a patient in need thereof, for the treatment of a cancer, are disclosed.
