  • Patent number: 11273177
    Abstract: The present disclosure provides methods of preparing tumor infiltrating cells engineered to express a pro-inflammatory polypeptide. The pro-inflammatory polypeptide is expressed from the tumor infiltrating cell to counter a generally immunosuppressive state in and around tumors resulting from an imbalance between the number and activation state of immune effector cells versus those of suppressor cells. Delivering the proinflammatory polypeptide via expression from the TICs, as distinct from systemic administration, reduces side effects from increased inflammation at sides remote from a tumor to be treated.

  • Patent number: 10653722
    Abstract: Graft-versus-host disease (GVHD) is a lethal complication of allograft transplantation. The current strategy of using immunosuppressive agents to control GVHD may cause general immune suppression and limit the effectiveness of allograft transplantation. Adoptive transfer of regulatory T cells (Treg) can prevent GVHD in rodents, indicating the therapeutic potential of Treg for GVHD in humans. However, the clinical application of Treg-based therapy is hampered by the low frequency of human Treg and the lack of a reliable model to test their therapeutic effects in vivo. Human alloantigen-specific Treg are generated from antigenically-naïve precursors in a large scale ex vivo using allogeneic activated B cells as stimulators. Here, a human allogeneic GVHD model is established in humanized mice to mimic GVHD after allograft transplantation in humans.

  • Patent number: 10596242
    Abstract: The present description relates to T-cell receptors (TCRs) binding to tumor-associated antigens (TAAs) for targeting cancer cells, T-cells expressing same, methods for producing same, and methods for treating cancers using same. In particular, the present description relates to TCRs and their variants that bind to HLA class I or II molecules with a peptide, such as IGF2BP3-001 have the amino acid sequence of KIQEILTQV (SEQ ID NO:1). The present description further relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present description relates to the immunotherapy of cancer. The present description furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T-cells ex vivo and transfer into patients.

  • Patent number: 10556053
    Abstract: A system for collecting MNCs to be treated with irradiation comprises a fluid circuit comprising a product container for receiving a MNC product. The system comprises a separator to work in association with the fluid circuit, the separator comprising a chamber for separation into RBCs, plasma, and an interface carrying MNCs between the RBCs and the plasma. A microprocessor-based controller is in communication with the separator, wherein the controller receives input of a target hematocrit for the MNC product. The controller also receives input for a total volume of whole blood and a number of cycles, and directs the interface and a portion of the RBCs into the product container for a resulting product volume comprising a volume of MNCs and a volume of RBCs. The controller automatically adjusts a RBC volume so that a ratio of RBCs within the MNC product to MNC product equals the target hematocrit.

  • Patent number: 10435456
    Abstract: The present invention relates to the field of protein expression. More specifically, the present invention provides compositions and methods for increasing the expression and signaling of proteins on cell surfaces. In particular embodiments, the present invention provides nucleic acids and amino acid sequences useful for improving/increasing protein expression on the cell surface. In several embodiments, the sequences are operably linked to the N-terminal end of the protein of interest. The nucleic acid sequence encoding the sequence tag and the protein can comprise part of an expression vector. The protein can be expressed with the N-terminal sequence tag. In certain embodiments, the sequences of the present invention can be used with one or more chaperone or accessory proteins. In particular embodiments, the one or more chaperone/accessory proteins are encoded by the same vector or separate vectors.
