Abstract
Introduction: Evidences gathered from several studies suggest that different genes are involved in pathways which contribute to modulate risk for AD. CLU gene is an example of these genes which encode clastrin. CLU is a functional protein that its expression increased in damaged regions of brain in AD patients. Another gene is toll like receptor2 (TLR2) that has an important role in induction of primary immune response against pathogenic microorganisms also play a role in neuroinflammation pathway. Recent investigations suggest that decrease or fully suppression of can be important in AD pathogens. On the other hand several studies show that estrogen has a protective role in brain. Aim: We used some polymorphisms in CLU, TLR2, ESR genes to investigate association between these genes and late onset Alzheimer disease. Material and Method: This study includes evaluation genotypes of four in these three genes by using PCR-RFLP method and statistical analysis in 160 LOAD patients and 163 healthy control subjects in North-west Iranian population (eastern Azerbaijan). Results: Statistical analysis of our results reveals that there is no significant association between CLU gene polymorphism and LOAD in this population (P=0.58) but we found significant associations between polymorphisms in TLR2 and ESR genes whit LOAD (P<0.001)., هدف: ما از پلی مورفیسم های سه ژن CLU و TLR2وESR برای مطالعه ارتباط بین این ژن ها و بیماری آلزایمر دیررس در افراد مبتلا استفاده کردیم. روش کار و مواد: این مطالعه شامل بررسی ژنوتیپ چهار پلی مورفیسم در این سه ژن و فراوانی آنها با استفاده از روش PCR-RFLP و استفاده از روش های آماری در 160فرد مبتلا به بیماری و 163 نفر کنترل از جمعیت شمال غرب ایران (آذربایجان شرقی) بوده است.یافته ها: بررسی آماری نتایج حاصل از این مطالعه ارتباط معنی داری بین پلی مورفیسم ژن CLU و بیماری آلزایمر در جمعیت مورد بررسی نشان نداد (P=0.58 )، لیکن آنالیز آماری به عمل آمده ارتباط معنی داری را بین پلی مورفیسم ژن های TLR و ESR و بیماری نمایان ساخت (P<0.001 ).
