两种表型不同的T细胞(Ly1+2-和Ly1-2+)参与了紫外线B光诱导的体内对单纯疱疹病毒1型传出迟发型超敏反应的抑制。

Two phenotypically distinct T cells (Ly1+2- and Ly1-2+) are involved in ultraviolet-B light-induced suppression of the efferent DTH response to HSV-1 in vivo.

Abstract

We have previously demonstrated that the delayed-type hypersensitivity (DTH) response to herpes simplex virus type 1 induced by subcutaneous injection with live virus was suppressed by irradiating mice with a low dose (96 mJ/cm2) of ultraviolet-B (UV-B) light 3 days before sensitization. In order to determine the nature of the suppression, cells from mice irradiated with UV-B before immunization with live virus were transferred to syngeneic animals that had been sensitized with live virus without prior UV-B exposure. Efferent suppression of DTH to HSV-1 was shown to be due to T lymphocytes, and two phenotypically distinct T cells were involved: an Ly1+2- subset and an Ly1-2+ subset.

摘要

我们之前已经证明,在致敏前3天用低剂量(96 mJ/cm2)的紫外线B(UV-B)照射小鼠,可抑制皮下注射活病毒诱导的对1型单纯疱疹病毒的迟发型超敏反应(DTH)。为了确定抑制的性质,将在用活病毒免疫前用UV-B照射的小鼠的细胞转移到已用活病毒致敏但未事先暴露于UV-B的同基因动物中。对HSV-1的DTH传出抑制被证明是由于T淋巴细胞,并且涉及两种表型不同的T细胞:Ly1+2-亚群和Ly1-2+亚群。
