Erythrocyte membrane abnormalities in patients with amyotrophic chorea with acanthocytosis. Part 1. Spin labeling studies and lipid analyses.
Low fluidity was observed in the erythrocyte membranes of familial chorea-acanthocytosis by spin labeling with 12NS. The high content of the saturated fatty acids support the finding of low fluidity. Other lipid contents (cholesterol and phospholipids) and the cholesterol/phospholipid ratio were within normal ranges. The sharp decrease in the parameter, (h0/h-1)1/2, suggests phase separation deep inside the patients' erythrocyte membrane matrix. This distortion of the membrane matrix may be caused by membrane components other than the lipid components.
