Lipoprotein deficiency was maintained for 48 h by applying 4-aminopyrazolo(3,4-d)pyrimidine in male albino rats and the effect on the structure and function of isolated adrenocortical cells was investigated. Neither the morphology nor the steroidogenic response of zona glomerulosa cells changed; however, in the zona fasciculata cells a marked reduction in the quantity of lipid droplets was associated with a decreased steroidogenic response to ACTH. The results indicate that despite lipoprotein deficiency, zona glomerulosa cells contain a reserve of intracellular cholesterol, thus retaining their responsiveness to stimulation. The fact that the lipoprotein deficiency does not affect lipid droplets located in the glomerulosa cells and in the fasciculata cells in a similar manner is probably due to the differences in their physical state and chemical composition.
