Abstract: The present invention relates to the field of immunotherapy, in particular, of cancer, more specifically, to adoptive T cell therapy or T cell receptor (TCR) gene therapy directed to an epitope derived from the cancer-testis antigen MAGEA4 presented on HLA-A*01, in particular, the immunodominant epitope of SEQ ID NO: 1. The invention provides a nucleic acid encoding a TCR alpha chain construct (TRA) and/or a TCR beta chain construct (TRB) of a TCR construct, wherein the TCR construct is capable of specifically binding to said epitope in the context of HLA-A*01. Proteins encoded by said nucleic acids, corresponding host cells and pharmaceutical compositions, e.g., for use in treating cancer such as melanoma, gastric cancer, head and neck, lung, breast, ovarian, bladder, and esophageal cancer, are also objects of the invention. In another aspect, the invention provides specific peptides comprising said epitopes, and pharmaceutical compositions comprising the same, e.g., for use in vaccination.

Abstract: The present invention pertains to the field of cell cultivation. Small scale cell culture systems are provided which simulate large scale perfusion cultures of suspension cells. The present invention in particular provides methods for cultivating cells wherein cell sedimentation is used to separate cells from culture medium for replacing part of the culture medium.

Abstract: The present invention pertains to a method for culturing a suspension of immortalized human blood cells, preferably cells of myeloid leukaemia origin or cells derived therefrom, wherein said method provides a high productivity, a high cell viability and growth rate and a high batch-to-batch consistency, and can be scaled up without altering these parameters.

Abstract: The present invention pertains to a system for culturing cells comprising a culturing bag and a continuous flow centrifuge wherein the cells are continuously separated from the supernatant and are recycled into the culturing bag. Further provided are methods for culturing cells and for producing a biological substance using the device for culturing cells, and the use of a bag for culturing cells in said device or said methods. In particular, a perfusion system for culturing cells is provided wherein the wave technology for culturing cells is combined with continuous flow centrifugation for separating the medium from the cells.
