(A?)-induced complement system activation plays an important role in Alzheimer's disease (AD)
Complement receptor 1 (CR1) is thought to contribute to A? clearance. A recent large genome-wide association study (GWAS) has identified significant association of two single nucleotide polymorphisms (SNPs) (rs6656401 and rs3818361) in the CR1 gene with AD in Caucasians. Here, we performed a case–control study to clarify whether the risk for sporadic late-onset AD (LOAD) might be influenced by these polymorphisms in a large Chinese cohort consisting of 254 patients and 357 healthy controls. The results revealed that there were significant differences in genotype (P = 0.02) and allele (P = 0.007) frequencies of the SNP rs6656401 but none in rs3818361 between AD patients and controls. The A allele of rs6656401 was associated with an increased risk of LOAD (P = 0.007, odds ratios/OR = 1.652). In the subgroup of APOE ?4 non-carriers, both the A of rs6656401 and T allele of rs3818361 were observed to be significantly higher in case than in controls (P = 0.002 and P = 0.035, respectively). For rs6656401, the logistic regression analysis revealed that the (AA + AG) genotypes has a 2.4-fold increased risk compared with the GG genotype (P = 0.049). Haplotype analysis identified the AT haplotype to increase the risk of LOAD (P = 0.03, OR = 2.44). This study provides the evidence that variations in the CR1 gene play an important role in the pathogenesis of sporadic LOAD in the Han Chinese population.

- Whole genome association study of brain-wide imaging phenotypes for identifying quantitative trait loci in MCI and AD: A study of the ADNI cohort
- Two types of refined imaging genetics analysis were performed for one of the top SNPs (NXPH1, rs6463843), including a VBM analysis assessing global grey matter (GM) density and a regional analysis of target phenotypes. These focused analyses resulted in interesting imaging genetics findings about the target SNP, including an overall and regional decrease in GM density associated with TT genotype relative to the GG genotype with an increased vulnerability to this effect in AD participants.
- intergenic 8805242 rs6463843 G or T TT
- rs6463843 (NXPH1), was selected for detailed imaging analyses since it was the only SNP strongly associated with both left and right hippocampi other than rs429358 (APOE) and rs2075650 (TOMM40). The results of a two-way ANOVA using VBM to compare the effects of baseline diagnostics group and rs6463843 (NXPH1) genotype on global GM density are shown in Fig. 4. After evaluating hippocampal GM density group means for each diagnosis-genotype group, we chose to contrast GG vs. TT (GG>TT) using all participants (n=715; 166 AD (44 TT, 78 GT, 44 GG); 346 MCI (82 TT, 170 GT, 94 GG); 203 HC (35 TT, 105 GT, 63 GG)). As shown in Fig. 4a, TT participants had significantly reduced global GM density throughout the brain relative to GG participants (p<0.01 (FDR), k=27).
- If the allele is rs429358(C) and the same chromosome also harbors the rs7412(C) allele, the combination is known as an ApoE4 allele. The ApoE4 allele has a strong influence on the risk of Alzheimer's disease.
The association study between DHCR24 polymorphisms and Alzheimer's disease
- DHCR24 55106113 rs600491 C or T TT
- The single locus association analysis indicated that men carrying the T allele of rs600491 had an increased risk of AD (OR 1.7 95% CI 1.2-2.4; P = 0.004, Bonferroni corrected P = 0.048 with 12 tests).
- The DHCR24 rs600491 genotype and allele distributions did not differ significantly between the AD and HC groups (p=0.881 for genotypes; p=0.845 for alleles). Stratification according to gender however, revealed a statistically significant association between T/T genotype and AD risk in men (AD:32.4%, HC: 16.9%; p=0.028), in contrast with the results in women (AD: 29.6%, HC: 33.8%;p=0.472). Men with the T/T genotype had a significantly increased risk for AD (OR=4.37; p=0.009)considering C/C genotype as reference category(OR=1).
Possible Prevention And Treatment for LOAD
- A Potential Role of the Curry Spice Curcumin in Alzheimer’s Disease
The crucial chemical is curcumin, a compound found in the spice. Alzheimer's is linked to the build up of knots in the brain called amyloid plaques. Turmeric reduced the number of these plaques by a half. The researchers also found that turmeric had other health benefits.
