Lectin-dependent cellular cytotoxicity by human lymphocytes is blocked by monoclonal antibodies to the sheep red cell receptor.

abstract：:When human peripheral blood lymphocytes (PBL) are cultured with either concanavalin A (Con A)-treated or control autologous T lymphocytes, the mitogenic responses of the PBL co-cultured with Con A-treated cells are much lower. We have investigated the cell surface receptor changes during culture of T cells with and wi...
