F. Licastro et al., Gene polymorphism affecting alpha 1-antichymotrypsin and interleukin-1 plasma levels increases Alzheimer's disease risk, ANN NEUROL, 48(3), 2000, pp. 388-391
Plasma levels of al-antichymotrypsin (ACT) and interleukin-1 beta (IL-1 bet
a) were increased in patients with probable Alzheimer's disease (AD). A com
mon polymorphism within ACT and IL-IP genes affected plasma levels of ACT o
r IL-1 beta, and AD patients with the ACT T,T or IL-1 beta T,T genotype sho
w-ed the highest levels of plasma ACT or IL-1 beta, respectively. The conco
mitant presence of the ACT T,T and IL-1 beta T,T genotypes increased the ri
sk of AD (odds ratio: 5.606, confidence interval: 1.654-18.996) and decreas
ed the age at onset of the disease.
