Viscoelastic synthetic antigen-presenting cells for augmenting the potency of cancer therapies Synthetic cells mimicking the viscoelastic and T-cell-activation properties of antigen-presenting cells provide substantial enhancements in the expansion and potency of engineered human cytotoxic T cells. ...
An antigen- presenting cell (APC) or accessory cell is a cell that displays foreign antigen complex with major histocompatibility complex (MHC) on its surface. T- cells may recognize this complex using their T-cell receptor (TCR). These cells process antigens and present them to T-cells....
