Background: Alzheimer’s disease (AD) is a neurodegenerative disease and is the most common because of late life dementia. Alteration of Secretary Phospholipase A2-IIA (sPLA2-IIA) may have an important role in membrane phospholipids metabolism and the pathogenesis of AD. The aim of our study was to determine serum levels and genetic variant of sPLA2-IIA in Alzheimer’s disease and compare to controls.
Methods: This study included 40 healthy unrelated individuals and 40 patients with AD. Serum levels and the polymorphisms of sPLA2-IIA enzyme were determined.
Results: In Alzheimer patients¸ the CC genotype and C allele frequencies of enzyme were significantly lower while the CG and GG genotypes and G allele frequencies of enzyme were significantly higher than controls. The mean concentration and mean rank of enzyme for CC genotype significantly were lower while the CG and GG genotypes of enzyme were significantly higher than controls.
Conclusion: The effect of different gene polymorphisms for the incident of AD is still unclear. We determined gene polymorphisms of sPLA2-IIA which may relate to AD. It can be suggest that a single or combination of gene polymorphisms have possible effect for development of AD. Further studies are needed to research the functional roles of sPLA2-IIA in the context of AD.
