Smart Immune is developing ProTcell: a pioneering, allogeneic,thymus-empowered T-cell therapy platform. ProTcell reinvigorates the thymus by introducing healthy allogeneic T-cell progenitors into the patient, which then develop into a full immune repertoire – an ‘off the shelf’ product for personalised medicine.
Smart Immune has replicated a human lymphoid niche ex vivo using its knowledge of CD34+ T cell differentiation.
A thymus-homing capability of unique T-cell progenitors so called ProTcell at the earliest point of lineage commitment.
A great capability of ProTcell to differentiate ex vivo in NK cells.
The ability to culture and expand such short-lived, fragile, unique T-cells populations in GMP conditions, using proprietary Notch ligand SIFP3.
