Antigen‐specific targeting of CD28‐mediated T cell co‐stimulation using chimeric single‐chain antibody variable fragment‐CD28 receptors
1 Oct 1996
Abstract excerpt
T cells require two distinct signals for optimal activation. One is an antigen-specific signal and is provided by engagement of the T cell receptor (TCR). The second is an antigen-independent signal mediated by engagement of the T cell surface molecule CD28 with members of the B7 family. To endow CD28 molecules with antibody-type recognition, we have constructed chimeric single-chain antibody variable fragment...
