  • Publication number: 20230227575
    Abstract: A therapeutic molecule (single chain-based antibody or ligand-based) optimized for expression and secretion from engineered T cells, which may be gamma delta (gd) T cells. When expressed from engineered gdT cells, the STAR will be secreted and mediate engagement between gdT cells and antigen/receptor on target cells. Binding mediates the formation of a cytolytic synapse between the gdT cell and the target cell leading to activation the gdT cells to release proteolytic enzymes that kill target cells.

A back plate is disposed between the first diaphragm and the second diaphragm. One or more posts extend from at least one of the first diaphragm or the second diaphragm towards the other through the back plate. The one or more posts prevent each of the first diaphragm and the second diaphragm from contacting the back plate due to movement of the first diaphragm and/or the second diaphragm towards the back plate.
