The physiological functions of murine CD2 and its ligand CD48 are uncertain. We have examined the role of the CD2-CD48 interaction in murine T cell activation using a series of Chinese hamster ovary (CHO) cell transfectants. CHO cells expressing I-Ad together with CD48 induced more potent activation of OVA-specific, I-Ad-restricted DO11.10-transgenic T cells than CHO cells expressing I-Ad alone. CD48 augmented proliferation and IL-2 production in response to antigen. The enhancing effect of CD48 was of the same magnitude as that seen for CD80 (B7-1). Conjugate assays revealed the ability of CD48 to increase adhesion between T cells and CHO transfectants. The enhancing effects of CD48 on T cell-antigen-presenting cell adhesion and T cell activation were inhibited by anti-CD2 monoclonal antibody. This report provides the first evidence that the CD2 ligand CD48 contributes to the interactions of murine CD4+ T cells with antigen-presenting cells.
