title: Association between polymorphisms in Interleukin-16 gene and risk of late-onset Alzheimer's disease.
abstract: Cytokines play important roles in the inflammation pathways. Alzheimer's disease (AD) is an inflammatory disease, and it is suggested that cytokines are able to influence AD. We investigated the association between IL16 polymorphisms and risk of AD in an Iranian population. The case group consisted of 144 individuals with AD and the control group included 173 healthy individuals. Genotyping of the IL16 rs4072111 C>T and rs1131445 T>C polymorphisms was determined using PCR-RFLP method. The frequency of rs4072111 CT genotype was significantly lower (P=0.007; OR=0.5, 95% CI: 0.3-0.8) in the patients (17.3%) than the control group (30%). The rs4072111 T allele was significantly lower (P=0.008; OR=0.5, 95% CI: 0.3-0.9) in the cases (8.6%) compared with the control group (15.6%). The IL16 rs4072111 polymorphism may be associated with susceptibility to AD and the T allele may have a protective role in the progression of AD in an Iranian population.
