title: Presence of I-region gene products on the cells and their products of the dengue virus-induced suppressor pathway.
abstract: We have studied both the cells and the suppressor factors of the dengue virus-induced suppressor pathway for the presence of I-region gene products. The suppressor activity of Ts1, Ts2 and Ts3 cells was abrogated by treatment with anti I-Jk or I-Ak anti-sera and complement. Both the suppressor factors were absorbed out by anti I-Jk and I-Ak immunosorbent columns. The activity of the suppressor factor was abolished by treatment with anti I-Jk antisera. Macrophage presentation of suppressor factor to precursors of Ts2 cells was abolished by treatment with anti I-Ak antisera and complement but not by anti I-Jk antisera. Thus I-region gene products were found throughout the dengue virus induced suppressor pathway.
