A method for activating and expanding isolated T cells, the method including adding to isolated T cells ligands presenting microbubbles having a flexible lipid shell with an inner bubble wall enclosing a gas and an outer bubble wall conjugated to ligands capable of achieving cell contact dependent juxtacrine signaling on the isolated T cells; and adding to isolated T cells ligands presenting microbubbles having a flexible lipid shell with an inner bubble wall enclosing a gas and an outer bubble wall conjugated to an antigen capable of forming an immunological synapse (IS) with the T cells.

Method for activating and expanding isolated T cells

A buoyancy enabled separation method for isolation from a sample including a variety of different cells a sparse subset of cells that is differentiated by a plurality of different cell surface markers. Microbubbles conjugated to antibodies are applied sequentially in a container with the previously used microbubbles disrupted prior to applying the next microbubbles conjugated to a different antibody. A system that includes a syringe-like container with a plunger and closeable opening. Further, a method for activating and expanding isolated T cells by applying antigen presenting microbubbbles having a flexible lipid shell mimicking an antigen presenting cell for generating immunological synapses.
