Ultrastructure of human E-rosettes: a re-examination.
In contrast with previous published studies, it has been found that T-lymphocytes interact through broad-base contacts with sheep erythrocytes (SRBC) in E-rosettes. An electron dense material was spontaneously observed between the lymphocyte and erythrocyte plasma membranes. These findings fit more closely with the known metabolic effects of SRBC upon lymphocytes and the SRBC-capping phenomenon.
