摘要

Ly-6C belongs to the Ly-6 family of glycosyl phosphatidylinositol-anchored surface glycoproteins and is expressed on a subset of mature CD8~+ T cells. Ly-6C ligation can mediate T cell activation and causes interleukin 2 secre- tion in cytolytic T cell clones. We characterize herein a new mAb 1G7.G10 against Ly-6C that recognizes an epitope in- volved in lymphocyte adhesion and in lymphocyte homing. Pretreatment of lymph node lymphocytes and of purified CD8+ T cells (but not of lymphocytes depleted of CD8+ T cells) with 1G7.G10 reduced their in vitro binding to lymph node high endothelial venules by 28/100 and 34/100, respectively.
