摘要

Background: Toll-like receptor 2 represents a reasonable functional and positional candidate gene for Alzheimer's disease as it is located under the linkage region of AD on chromosome 4q, and functionally is involved in the microglia-mediated inflammatory response and amyloid-β clearance. The -196 to -174 del polymorphism affects the TLR2 gene and alters its promoter activity.Methods: We recruited 800 unrelated Northern Han Chinese individuals comprising 400 late-onset AD patients and 400 hea...更多

Background: Toll-like receptor 2 represents a reasonable functional and positional candidate gene for Alzheimer's disease as it is located under the linkage region of AD on chromosome 4q, and functionally is involved in the microglia-mediated inflammatory response and amyloid-β clearance. The -196 to -174 del polymorphism affects the TLR2 gene and alters its promoter activity.Methods: We recruited 800 unrelated Northern Han Chinese individuals comprising 400 late-onset AD patients and 400 healthy controls matched for gender and age. The -196 to -174 del polymorphism in the TLR2 gene was genotyped using the polymerase chain reaction method.Results: There were significant differences in genotype and allele frequencies of the -196 to -174 del polymorphism between LOAD patients and controls. The del allele was associated with an increased risk of LOAD . When these data were stratified by apolipoprotein E ε4 status, the observed association was confined to ApoE ε4 non-carriers. Logistic regression analysis suggested an association of LOAD with the polymorphism in a recessive model .Conclusions: Our data suggest that the -196 to -174 del/del genotype of TLR2 may increase risk of LOAD in a Northern Han Chinese population.收起
