Polymorphonuclear leukocyte membrane fluidity and cytosolic Ca2+ concentration in diabetes mellitus.
|
| Abstract |
We evaluated polymorphonuclear membrane (PMN) fluidity in 32 subjects with type 1 diabetes mellitus, 38 subjects with type 2 diabetes mellitus and 38 normal control subjects, by marking intact and unstimulated PMN cells with the fluorescent probe 1-[4-(trimethylamino)phenyl]-6-phenyl-1,3,5-hexatriene (TMA-DPH). We also evaluated PMN cytosolic Ca2+ content by marking intact and unstimulated PMN cells with the fluorescent probe Fura 2-AM. PMN membrane fluidity differentiated normal subjects from type 1 and 2 diabetic subjects. The PMN cytosolic Ca2+ concentration did not discriminate type 1 and 2 diabetic subjects from normal control subjects. No statistical correlation was found between PMN membrane fluidity and PMN cytosolic Ca2+ concentration in any of the groups of subjects, nor were significant correlations found between PMN membrane fluidity and cytosolic Ca2+ concentration in several plasma parameters (serum glucose, cholesterol and triglycerides). In conclusion, in type 1 and 2 diabetic patients we found a decrease in PMN membrane fluidity and this decrease, which was greater in type 2 diabetic patients, may be a marker of PMN dysfunction.
