FIGURE 5.
Spleen cells from arrβgal mice inhibited the in vitro Ag response of naive βgalTCR T cells. (A) 5 × 106 non-irradiated splenocytes from arrβgal mice or control B10.A mice were cultured with/without 1 × 105 βgalTCR CD4+ T cells and 50 μg/mLβgal as indicated. Supernatants were collected at 72 h after Ag stimulation and assayed by ELISA. The results are given as the mean ± SD, P values (t test) are indicated.
