Regulation of putrescine uptake in Leishmania mexicana promastigotes.

Putrescine uptake of Leishmania mexicana promastigotes is tightly regulated by polyamine intracellular concentrations. This uptake, markedly stimulated after parasite treatment with alpha-difluoromethylornithine (DFMO) for 48 to 72 hrs., was strongly repressed by exposure of Leishmania cultures to e...
