Abstract

The nature of effector cells which mediate delayed-type hypersensitivity (DTH) to dengue type 2 virus and the influence of the H-2 complex on the cellular transfer of DTH was investigated. The DTH effector cells appeared to consist of two types of T cells, one Lyt-1.1+, the other Lyt-2.1+ or, alternatively, an interaction between these two T cell subsets may be required for maximal expression of DTH. Cellular transfer of DTH reactivity also required compatibility at the K and D or I region of the H-2 complex. Compatibility at the D region alone was not sufficient for transfer of DTH. The significance and implications of these findings are discussed.

摘要

研究了介导对2型登革病毒迟发型超敏反应(DTH)的效应细胞的性质以及H-2复合体对DTH细胞转移的影响。DTH效应细胞似乎由两种类型的T细胞组成,一种是Lyt-1.1+,另一种是Lyt-2.1+,或者,这两个T细胞亚群之间的相互作用可能是DTH最大表达所必需的。DTH反应性的细胞转移还需要H-2复合体的K和D或I区域的相容性。仅D区域的相容性不足以进行DTH的转移。讨论了这些发现的意义和影响。
