title: Incorporation of radioactive phosphate from adenosine triphosphate into phosphatidylinositol-4-phosphate in human peripheral blood hypodense eosinophils is less than in the normodense eosinophils.
abstract: Peripheral blood eosinophils from patients with atopic dermatitis and normal healthy controls were isolated on a Percoll gradient and incubated with [gamma 32P]ATP in the presence of Mg2+. After stopping the reaction, lipid extraction was performed with acidic medium and phospholipids were separated by thin-layer chromatography on 1% (w/v) oxalic acid-impregnated silica gel plates. In the autoradiographs considerable amounts of the radioactivity were found to be incorporated into phosphatidylinositol-4-phosphate. 32P incorporation into phosphatidylinositol-4-phosphate in hypodense eosinophils from atopic dermatitis patients was less than in normodense eosinophils from the same patients and controls.
