We have found that an I-J+ I-A- antigen-presenting cell (APC) is required for Ts3 activation in vivo. Together with the I-J restriction previously reported for Ts3 induction (Takaoki, M., M.-S. Sy, A. Tominaga, A. Lowy, M. Tsurifiji, B. Benacerraf, R. Finberg, and M. I. Greene, 1982, J. Exp. Med., 156:1325), it appears that this I-J+ APC is responsible for I-J restriction in the triggering of Ts3. This restriction may be exerted via a pre-Ts3 associative recognition of antigen and I-J encoded determinants, analogous to the T helper recognition of antigen in the context of I-A and I-E determinants.
我们发现,体内Ts3激活需要I-J⁺I-A⁻抗原呈递细胞(APC)。结合先前报道的Ts3诱导的I-J限制(高木,M.,M.-S. 西,A. 富永,A. 洛伊,M. 鹤桥,B. 贝纳塞拉夫,R. 芬伯格,和M. I. 格林,1982年,《实验医学杂志》,156:1325),看来这种I-J⁺APC在Ts3触发中负责I-J限制。这种限制可能通过Ts3前体对抗原和I-J编码决定簇的联合识别来施加,类似于T辅助细胞在I-A和I-E决定簇背景下对抗原的识别。
