The in vitro spontaneous formation of sheep red blood cell (SRBC) (E) rosettes by peripheral blood lymphocytes is altered in vitro by the addition of micro molar quantities of zinc chloride. Appropriate concentrations of zinc chloride cause marked enhancement of rosette formation, both in normal subjects and in cancer patients with low initial E rosette values. The effect is dependent upon zinc treatment of the lymphocyte and not the SRBC. Other zinc induced effects on E rosettes include retardation of temperature dependent spontaneous decay, increased mechanical stability due to enhanced SRBC lymphocyte bonding, and retardation of 'capping.' The formation of EAC rosettes is not altered by the presence of zinc.
