title: Lectin-dependent cellular cytotoxicity by human lymphocytes is blocked by monoclonal antibodies to the sheep red cell receptor.
abstract: Investigating the functional effects of anti-T cell monoclonal antibodies (obtained through the Second International Workshop on Human Leucocyte Differentiation Antigens), antibodies to the sheep red cell receptor (CD2) were found to block lectin-dependent cytotoxicity. Blocking was seen with all anti-CD2 reagents tested regardless of epitope specificity, immunoglobulin subclass or other factors. Antibodies to other T cell differentiation antigens had no effect.
