TS1 and TS2 cell lines inhibit antibody synthesis in vivo. (CBy.D2) F1 mice were immunized with TNP-KLH with or without injection of 5 × 106 cells from either one of the lines. Data represent the mean of anti-TNP IgG levels in the sera of the experimental animals 14 days after immunization with TNP-KLH. Values are mean ± SEM. *P < 0·01 versus controls.
