Physiological induction of a proliferative response to B5 during CIA. DBA/1LacJ mice were immunized with CII for the induction of CIA. 35 d later, splenic cells were assayed for proliferation in response to a concentration (7 μM) of different TCR peptides, B1 and B5. [3H]thymidine incorporation was measured by liquid scintillation counting. There was no significant response to B5 in nonimmunized mice, nor in mice challenged with HEL, 35 d after immunization. Individual responses of eight individual mice are shown.
