- Abstract
- Background/Aims: Chemokine receptor 5 (CCR5) is a receptor for several chemokines, including regulated upon
activation, normal T-cell-expressed and -secreted (RANTES; also known as CCL5) and macrophage inflammatory protein
1 (MIP-1), and mediates the recruitment of monocytes and their differentiation to macrophages during the inflammatory
process. As such, CCR5 plays an important role in the development and progression of atherosclerosis, which has an
underlying inflammation component and contributes to the development or progression of diabetic complications. Several
studies have reported that a genetic variation of the CCR5 gene with A/G at basepair 59029 (59029 A/G) was associated
with diabetic complications, although conflicting data exist. We evaluated the association of the CCR5 59029 A/G
polymorphism with diabetic complications in type 2 diabetes patients.
Methods: We conducted a case-control study, enrolling 325 patients with type 2 diabetes. We examined the association
of CCR5 genotypic variations with diabetic nephropathy, retinopathy, and macrovascular complications such as coronary
heart disease and stroke. Genotyping was performed using the polymerase chain reaction and restriction fragment length
polymorphism technology with Bsp1286I restriction enzyme.
Results: We determined no allelic association of CCR5 59029 A/G with diabetic nephropathy (p=0.500) in the male or
female patients. Diabetic retinopathy and macrovascular complications such as coronary heart disease and stroke were not
associated with the 59029 A/G polymorphism. Among those patients with diabetic nephropathies, those with the GG
genotype showed a tendency toward higher serum levels of LDL-cholesterol.
Conclusions: These results suggest that that the 59029 A/G polymorphism of the CCR5 gene is not associated with
diabetic complications in type 2 diabetes patients. Further studies are required to understand the role of CCR5
polymorphisms in the development of diabetic complications. (Korean J Med 75:428-435, 2008)
