Compositions and methods are presented that allow for an enhanced immune response against a GPI-anchored tumor associated antigen by modification of the protein portion of the TAA to include a transmembrane domain and a trafficking signal that directs the modified protein to the endosomal or lysosomal compartment. Most preferably, the modified protein will no longer have a GPI anchor or GPI attachment sequence.

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.

Compositions and methods for displaying antibodies in the periplasmic space of yeast cells are disclosed. In particular, antibodies are linked to a cell membrane-spanning transmembrane domain, a cell-membrane associated protein domain that is on the external face of the yeast cell membrane, a protein that binds to the inner face of the yeast cell wall, or a periplasmic protein in order to display the antibodies in the yeast periplasmic space. In addition, a target protein of interest can be coexpressed in yeast such that it is localized to the plasma membrane or periplasmic space and accessible to binding by displayed antibodies. The disclosure further relates to high-throughput screening of antibody libraries using yeast cell periplasmic display.

The present disclosure concerns recombinant yeast host cells expressing cell-associated heterologous food and/or feed enzymes which are expressed during the propagation phase of the recombinant yeast hosts cells. The recombinant yeast host cells can be used in a subsequent production process to make food and/or feed products, for example, baked products.

A drug delivery platform providing flexible fine tune of cell therapy is disclosed herein. Particularly, an engineered fusion protein is coupled with a high affinity ligand carrying at least one payload of drug to be internalized by the transplanted cell to observe or regulate transplanted cell therapy effects.
