Compositions and methods are disclosed herein for producing one or more immunoglobulins in an isolated B lymphocyte cell line. An isolated cell line includes an isolated B lymphocyte cell line capable of expressing at least one exogenously incorporated membrane immunoglobulin reactive to a first antigen and at least one endogenous secreted immunoglobulin reactive to a second antigen.

Described herein is a reliable method for preparing a potent vaccine useful for immunotherapy comprising the step of cryopreserving a population of cells undergoing immunogenic cell death, and using such cells to activate dendritic cells for use in immunotherapy. In a specific embodiment, the method comprises cryopreserving cancer cells undergoing cell death, which can be used to prepare a pharmaceutical composition for immunotherapy against cancer.

This invention provides a system of providing and a process of creating personalized immunotherapeutic compositions for a subject having a disease or condition, including therapeutic vaccine delivery vectors comprising gene expression constructs expressing peptides associated with one or more neo-epitopes or peptides containing mutations that are specific to an subject's cancer or unhealthy tissue. The invention further provides a scalable fully enclosed single use cell growth system, wherein the entire process of manufacturing of personalized immunotherapeutic compositions, up to and including dispensing said composition into containers for patient delivery is carried out within a single enclosed fluid flow path.

Disclosed herein are compositions and methods for treating or inhibiting prostate cancer. The compositions include a MHC molecule including covalently linked first and second domains, wherein the first domain is an MHC class II 1 domain and the second domain is an MHC class II 1 domain, wherein the amino terminus of the 1 domain is covalently linked to the carboxy terminus of the 1 domain, and a prostate specific antigen peptide covalently linked to the first domain. The methods include administering a disclosed MHC molecule to a subject with prostate cancer.

The present invention relates to an ex vivo, fast and efficient process to obtain activated antigen-presenting cells that are useful for therapies against cancer and immune system-related diseases. At the same time, it is related to a cellular composition that contributes to stimulate the activated antigen-presenting cells to induce a specific immune response against tumors in patients with cancer or other pathologies involving immune responses.

The present invention provides a chimeric cytokine receptor (CCR) comprising: (i) an exodomain which binds to a ligand selected from a tumour secreted factor, a chemokine and a cell-surface antigen; and (ii) a cytokine receptor endodomain.
