The present invention is directed to compositions comprising modified SMARCB1 and uses thereof.

Provided herein are extracellular vesicle (EV) (a.k.a. exosome) compositions for specifically targeting the delivery of a therapeutic agent to particular cells and/or tissues in a subject, as well as methods of making and methods of using said compositions. The compositions and methods disclosed herein are useful for targeted drug delivery in the treatment of diseases in which a cell surface receptor is overexpressed, such as, for example, cancer.

The invention refers to a single-chain circular permuted caspase-2 comprising the following structure from N- to C-terminus: i) a small subunit of a caspase-2, or a functionally active variant thereof; and ii) a large subunit of a caspase-2, or a functionally active variant thereof, wherein said cp caspase-2 comprises one or more amino acid substitutions increasing P1′ tolerance of said cp caspase-2 compared to a cp caspase-2 without said amino acid substitutions.

The present disclosure relates, according to some embodiments, to systems, apparatus, compositions, methods, and workflows that include DNase I variants with desirable properties including, for example, salt tolerance. A DNase I variant, in some embodiments, may have an amino acid sequence that is at least 85% identical, at least 90% identical, at least 95% identical, and/or at least 98% identical to SEQ ID NO:1 and may be identical to SEQ ID NO:1 at one or more positions selected from the group of positions corresponding to L29, A35, D87, Q88, S94, P103, T108, P121, P132, A135, D145, E161, G172, P190, H208, and A224 of SEQ ID NO:1.

The present invention relates to nucleic acid molecules comprising a nucleic acid sequence encoding a membrane-bound biotin mimetic peptide (BMP) or biotin acceptor peptide (BAP). The invention also relates to a method for selection of high producer cells secreting a protein of interest.

The present technology provides methods and compositions for the treatment of inflammatory and/or tissue damage conditions. In particular, the use of Smad7 compositions delivered locally or systemically to a site of inflammation and/or tissue damage is described. Other specific embodiments concern treatment or prevention of side effects caused by radiation and/or chemotherapy, including but not limited to oral and gastric mucositis. Also provided are codon-optimized nucleic acids encoding for Smad7 fusion proteins.

The present disclosure provides compositions and methods related to transcription factor systems. Such systems provide for modular and tunable protein expression driven by regulated transcriptional activity.

The present disclosure provides a heterodimeric, conditionally active chimeric antigen receptor (CAR), and a nucleic acid comprising a nucleotide sequence encoding the CAR. The present disclosure provides cells genetically modified to produce the CAR. A CAR of the present disclosure can be used in various methods, which are also provided.

The invention relates to antibody conjugates (e.g., a bispecific antibody), drug and nanoparticle compositions and methods and compositions for generating them. This invention further relates to methods of using these compositions for imaging, diagnosing or treating a disease.

The present invention provides a gentle and low cost means to isolate extracellular vesicles, including exosomes, from a surrounding sample. In particular the invention relates to the use of a fusion protein and biopolymer beads in such methods. Methods, compositions and medical uses of such compositions are also provided.
