[Study of endocytosis in mouse peritoneal macrophages using colloid particles labelled with Technetium 99 m].
Endocytosis of radioactive technetium colloïd by murine peritoneal macrophages cultures is measured after incubation. The results show a time and temperature dependant phenomen, reduced by hydrocortisone and inhibitor of glycolysis (NaF). Cytochalasine B and colchicine have no effect on the uptake of Technetium sulfur colloïd. These results suggest that the pinocytosis of technetium colloïd is independent of the actions of microfilaments and microtubules.
