The Terminal Complement Complex (TCC) in the Plasma of Patients with Type 1 Diabetes Mellitus. Relationship with Albumin Excretion Rate
Increased TCC levels were found to be present in the plasma of patients with type 1 diabetes associated with the presence of anti-heparan sulfate antibodies and increased urinary excretion of albumin. The authors suggest a role of terminal complement activation in the pathogenesis of diabetic nephropathy.
IgG anti-endothelial cell antibodies (AECA) in type I diabetes mellitus; induction of adhesion molecule expression in cultured endothelial cells
SUMMARYAECA were detected in 25 of 71 patients with type 1 diabetes mellitus and in two of 33 healthy subjects. Patients with diabetes of < 1 year duration and those with long-standing disease had the highest levels of these antibodies. Inhibition studies suggest that at least part of the AECA reactivity is due to cross-reactive anti-ssDNA antibodies. AECA-positive sera were able to increase intercellular adhesion molecule-1 (ICAM-1) and E-selectin on human umbilical vein endothelial cells (HUVEC). Increased binding of polymorphonuclear (PMN) cells was also found to accompany raised E-selectin expression. Soluble ICAM-1 and E-selectin were also found to be increased in the sera of AE…
