| Abstract: | (1) Following incubation of thymocytes with nylon wool at 37 degrees C, the eluted cells showed an increase in the number of microvilli per cell and a concominant elongation of the microvilli (0.22 mum versus 1.15 mum. (2) Cyclic adenosine monophosphate (cylic AMP) levels were lowered by 30-50% in nylon wool-treated thymocytes. (3) Nylon wool-treated cells showed an impaired Na+-dependent amino acid transport system (2-aminoisobutyrate) whereas the Na+-independent amino acid transport system (1-aminocyclopentane-1-carboxylate) was unaffected. |
