Described herein are compositions and techniques related to generation and therapeutic application of artificial synapses. Artificial synapses are engineered extracellular vesicles, including exosomes, which incorporate sticky binders on their surface to anchor signaling domains against biological targets, such as receptors. These engineered additives can be organized in genetic vector constructs, expressed in mammalian cells, wherein the sticky binders attach to extracellular vesicles such as exosomes, thereby presenting their joined signaling domains which are rapidly taken up by recipient cells. Artificial synapses adopt the hallmark biophysical and biochemical features of extracellular vesicles, allowing for rapid deployment and scale-up. Importantly, this strategy can allow for kinetically favorable signal generation and signal propagation. This includes, for example, increasing density of agonist presentation to support receptor clustering—an onerous barrier for traditional receptor targeting strategies.

The present invention relates to a recombinant nucleic acid construct encoding a kallikrein-2 fusion protein. The kallikrein-2 fusion protein includes a first nucleotide sequence encoding kallikrein-2 (KLK2), and a second nucleotide sequence encoding a glycosylphophatidylinositol (GPI) attachment sequence, where the GPI attachment sequence encoding nucleotide sequence is positioned 3′ to the KLK2 encoding nucleotide sequence. Also disclosed are vectors, preparations of cells, and methods of use thereof

A strain of an Apicomplexa of the family Sarcocystidae, wherein the strain is replicative and expresses one or more heterologous protein(s) selected from the group including therapeutic proteins, antigens, recombinant surface receptor or combinations thereof, and wherein the strain is selected from the group including Toxoplasma gondii and Neospora caninium. Also, the use of the strain for preventing or treating cancers or infectious diseases in a subject in need thereof.

Provided herein is technology relating to treatment of Ras-associated diseases and particularly, but not exclusively, to compositions, methods, systems, and kits for decreasing Ras activity using a neurofibromin 1 GTPase-activating protein-related domain gene therapy construct.

The present invention relates to anti-ROR2 inhibitors and uses thereof in treating and/or preventing cartilage loss.

The present disclosure concerns recombinant yeast host cells expressing cell-associated heterologous proteins which are expressed during the propagation phase of the recombinant yeast host cells and processes for propagating same. The recombinant yeast host cells can be 5 used to make a yeast composition or a yeast product enriched in the heterologous proteins.

The present invention is directed to methods of screening populations of transgenic cells for cells that produce a protein of interest. The methods comprise culturing transgenic cells in culture conditions that include at least one non-natural amino acid (nnAA) in the cell culture medium. The transgenic cells comprise at least one polynucleotide that codes for a fusion protein with a first domain coding for a protein of interest and a second domain coding for a domain that facilitates detection of the transgenic cells that express the protein of interest when the transgenic cell expresses the second domain.
