Inhibition of autologous rosette formation by monoclonal antibody to the sheep erythrocyte receptor.

Abstract

The commercial monoclonal HuLyT-3, and which recognizes a 55,000-dalton polypeptide associated with the receptor for SRBC on human T lymphocytes, was capable of blocking rosette formation between human T cells and autologous human RBC. Lysostripping of the T cell surface with HuLyT-3 abolished rosette formation with both sheep and autologous RBC. The data suggest that a common structure is involved in the spontaneous rosetting of both sheep and human RBC by human T cells.
