title: Permanent inhibition of capping of spleen lymphocytes from neonatally oestrogen-treated female mice.
abstract: Female mice of the NMRI strain were injected with 5 microgram diethylstilboestrol (DES) or oestradiol-17 beta for the first 5 days after birth. Controls were given olive oil only. At the age of 4-6 months, the spleen lymphocyte population from the DES females had about half the percentage of cells undergoing capping after exposure to concanavalin A (Con A) as controls. The results from the oestradiol-injected females varied. After treatment of lymphocytes from DES females with colchicine, the percentage cells capping was as in control females. Binding studies did not reveal any difference in Con A receptor affinity or receptor number between DES females and controls.
