Cell culture systems and methods provide improved immunotherapeutic product manufacturing with greater scalability, flexibility, and automation. Cell culture systems are configured with interchangeable cartridges, allowing versatility and scalability. Systems are configured to have multiple connected cell culture chambers, which allows parallel processing of different types of cells. Gas-impermeable cell culture chambers and methods for generating cells in closed systems prevent contamination and user error. Methods for recycling cell culture medium provide additional efficiencies.

Disclosed are means, methods and compositions of matter useful for induction of immunity towards cancer stem cells by providing a dendritic cell, wherein said dendritic cells express BORIS and/or peptides derived from BORIS, wherein said dendritic cell is cultured in the presence of one or more immunocytes. In one embodiment said dendritic cells are derived from umbilical cord blood sources and allogeneic to T cells, which are expanded ex vivo and used for the purposes of immunotherapy.

The present invention relates to methods for producing immuno-stimulatory autologous dendritic cells. The present invention further relates to the use of such cells for treating patients suffering from hyper-proliferative disease such as cancer.

The present invention relates to a method for the preparation of an immunogenic lysate from mesothelioma tumor cells, to such a lysate and to dendritic cells loaded with the lysate, the present invention further relates a pharmaceutical composition comprising such lysate or dendritic cells, to the use of the lysate, and to said loaded dendritic cells or said pharmaceutical composition for use in the prevention or treatment of mesothelioma.

Methods and compositions for use in generating or promoting an immune response to cancer or an infection, comprising promoting differentiation of neutrophils into dendritic cells using a combination of GMCSF and (i) an immune complex comprising an antigen and an antibody comprising an Fc region that binds to FcγRIIA or FcγRIIIB, (ii) a conjugate comprising an antigen and an anti-FcγRIIIB antibody, or (iii) an anti-FcγRIIIB antibody.

Disclosed is a method for detecting regulatory dendritic cells, the method comprising step a: detecting the presence or absence of one or more types of molecules on a cell surface in a cell population that comprises regulatory dendritic cells; and step b: identifying regulatory dendritic cells on the basis of the presence or absence of the one or more types of molecules. Also disclosed is a method for producing a cell population enriched for regulatory dendritic cells, the method comprising step 1: detecting the presence or absence of one or more types of molecules on a cell surface in a cell population that comprises regulatory dendritic cells; and step 2: obtaining a cell population enriched for regulatory dendritic cells on the basis of the presence or absence of the one or more types of molecules. Further disclosed is a cell population enriched for regulatory dendritic cells obtained by the method.

Non-naturally occurring vesicles derived from bacteria, e.g., pathogenic bacteria, methods for making the vesicles, and methods for using compositions of these vesicles are disclosed. Methods of using the vesicles include prevention and/or treatment of bacterial infections. Also provided herein are compositions that include vesicles derived front bacteria and tumor vesicles, methods for making the tumor vesicles, and methods for using the compositions of bacterial vesicles and tumor vesicles. Methods of using the compositions of bacterial vesicles and tumor vesicles include treatment of cancer in a subject. Tumor vesicles may be derived from cancer cells present in the subject to be treated or from a cancer cell line expressing at least one neoantigen. The neoantigen may be specific to the subject and may have been identified by sequencing of the cancer cells from the subject. The neoantigen may be a neoantigen known to be commonly expressed in a particular type of cancer.

A method and device for preferentially delivering a compound such as an antigen to the cytosol of an immune cell. The method comprises passing a cell suspension comprising the target immune cell through a microfluidic device and contacting the suspension with the compound(s) or payload to be delivered.
