  • Use of ligands for the programmed cell death receptor conjugated to solid supports for cultivating human regulatory T cells
    Patent number: 9994817
    Abstract: Disclosed are methods for isolating, cultivating, and/or cells including regulatory T cells (Tregs). The methods typically include cultivating cells including Tregs in a culture media comprising a ligand for programmed cell death receptor (PD-1) conjugated to a solid support. Suitable ligands may include PD-L1 and suitable solid supports may include magnetic or paramagnetic beads where the methods further include removing the PD-L1/bead conjugates after the Tregs have been isolated, cultured, and/or expanded.
    Type: Grant
