Abstract: Compositions and methods are presented in which selected polypeptide compounds bind to CTLA-4. Most typically, binding is mediated by selected VH and/or VL domains, and preferred compounds are prepared as scFv, IgG, or CAR.

Abstract: Described herein are methods of making recombinant cells using an in silico-generated pathway map of an endogenous pathway in a cell of interest to determine, in silico, a predicted effect of incorporating a recombinant nucleic acid into the endogenous pathway; and based on the predicted effect, incorporating the recombinant nucleic acid into the endogenous pathway in the cell of interest such that activation of the endogenous pathway regulates expression of the recombinant nucleic acid.

Abstract: The present disclosure relates to recombinant production reporter cells comprising a logic gate such that an expressible sequence (e.g., a reporter gene) is expressed after the occurrence of triggering event related to a stage of production or an environmental condition of a biological production system. Nucleic acids, kits, and methods for making and using the recombinant production reporter cells are also disclosed herein.

Abstract: Anti-SLAMF7 Fab fragments, antibodies, biparatopic antibodies, and chimeric antigen receptors (CARs) are provided herein. Also provided are polynucleotides encoded the anti-SLAMF7 Fab fragments, antibodies, biparatopic antibodies, and CARs. The anti-SLAMF7 Fab fragments, antibodies, biparatopic antibodies, and CARs are useful for the prevention and/or treatment of cancer, such as multiple myeloma. Also provided is a combination therapy including administration of the anti-SLAMF7 Fab fragments, antibodies, biparatopic antibodies, and CARs with an IL-16 or an IL-15 agonist.

Abstract: The present disclosure relates to recombinant therapeutic cells comprising recombinant sensor proteins, such that a therapeutic molecule is expressed after the occurrence of two separate triggering events that are sensed by the sensor proteins. Nucleic acids, kits, and methods for making and using the recombinant therapeutic cells are also disclosed herein.

Abstract: Compositions and methods for NK cell based treatments, and particularly NK cells that express and intracellularly retain IL-2, are presented in which the NK cells are stimulated with a chimeric protein that has a cancer cell targeting portion and an IL-12 portion. Beneficially, such chimeric protein has substantially reduced systemic toxicity and induces IFN-? secretion in a targeted manner. Moreover, chimeric proteins contemplated herein also significantly enhanced IFN-? secretion in NK cells that express and intracellularly retain IL-2 as compared to native NK cells. Preferred chimeric proteins comprise SEQ ID NO:1 or SEQ ID NO:2, and SEQ ID NO:3.

Abstract: Antibodies, fragments thereof, and chimeric proteins comprising same are presented that have specific binding activity against T-cell immunoglobulin mucin receptor 3 (TIM3). Advantageously, contemplated molecules can be used in pharmaceutical compositions for immune therapy, particularly in individuals receiving cancer vaccines and/or checkpoint inhibitor treatment.

Abstract: Modified T cell receptors, cells comprising the modified T cell receptors, nucleic acids encoding the modified T cell receptors, and methods for using the modified T cell receptors are contemplated. Modified T cell receptor comprising two peptide chains are disclosed herein. The two peptide chains may be the same or different, and each peptide chain comprises an extracellular domain comprising a variable region, a constant region, and a connecting peptide, a transmembrane domain, and an intracellular domain comprising a CD28 region and a CD3 ? ITAM region. Nucleic acids encoding the modified T cell receptors, and vectors comprising the nucleic acids are also disclosed. Additionally, a method for treating cancer and/or a viral infection is disclosed comprising administering a cell comprising the modified T cell receptor.

Abstract: Provided herein are novel soluble-fusion protein complexes comprising interleukin 18 (IL-18) and interleukin 12 (IL-12) polypeptide domains. Also provided are compositions comprising the soluble-fusion protein complexes as well as methods of using the soluble-fusion protein complexes.

Abstract: Compositions, methods and uses of a recombinant virus and/or recombinant viral vector encoding a distinct antibody or antibody fragment generated from high-diversity nucleic acid library are presented. Preferably, the recombinant virus is genetically modified, low immunogenic virus, for example, an E2b-deleted adenovirus. The high-diversity nucleic acid library comprises or is derived from (1) a VH-CDR1/2 sub-library, (2) a plurality of VH-CDR3 sub-libraries, and (3) a VL sub-library, each of which comprises a plurality of members. Preferably, each member of the sub-libraries comprises at least one random cassette that has a plurality of degenerate base positions. In an especially preferred embodiment, at least portions of at least two members of the VH-CDR1/2 sub-library, the plurality of VH-CDR3 sub-libraries, and the VL sub-library are recombined to form an expression library member in an expression library, where each member of the expression library encodes a distinct antibody or antibody fragment.
