Abstract
BACKGROUND Neuroinflammation plays an important role in Alzheimer's disease (AD). During this process, activated microglia release pro-inflammatory cytokines such as interleukin (IL)-1α, IL-1β, IL-6, and tumor necrosis factor α (TNFα) that participate in neuron damage, but also anti-inflammatory cytokines (such as IL-10), which maintain homeostasis of immune response. Previous studies showed the association of IL-1α -889C/T (rs1800587), IL-1β-1473G/C (rs1143623), IL-6 -174C/G (rs1800795), IL-10 -1082G/A (rs1800896), and TNFα -308A/G (rs1800629) polymorphisms with AD. OBJECTIVE We aimed to investigate whether people with certain IL-1α, IL-1β, IL-6, IL-10, and TNFα genotypes in these polymorphisms are more prone to develop AD-related pathology, reflected by pathological levels of cerebrospinal fluid (CSF) AD biomarkers including amyloid-β1-42, total tau (t-tau), tau phosphorylated at Thr 181 (p-tau181), Ser 199 (p-tau199), and Thr 231 (p-tau231), and visinin-like protein 1 (VILIP-1). METHODS The study included 115 AD patients, 53 patients with mild cognitive impairment, and 11 healthy controls. The polymorphisms were determined using real-time polymerase chain reaction. Levels of CSF biomarkers were determined by enzyme-linked immunosorbent assay. RESULTS A significant increase in p-tau CSF levels was found in patients with the AA IL-10 -1082G/A and GG TNFα -308A/G genotypes, and in carriers of a G allele in IL-1β -1473C/G and IL-6 -174C/G polymorphisms. t-tau levels were increased in carriers of a G allele in IL-1β -1473C/G polymorphism. An increase in VILIP-1 levels was observed in patients with CG and GG IL-1β -1473C/G, GC IL-6 -174C/G, and GG TNFα -308A/G genotype. CONCLUSION These results suggest that persons carrying certain genotypes in IL10 (-1082G/A), IL1β (1473C/G), IL6 (-174C/G), and TNFIα (-308A/G) could be more vulnerable to development of neuroinflammation, and consequently of AD.

Abstract
BACKGROUND Patients with brain tumors treated with radiotherapy (RT) and chemotherapy (CT) often experience cognitive dysfunction. We reported that single nucleotide polymorphisms (SNPs) in the APOE, COMT, and BDNF genes may influence cognition in brain tumor patients. In this study, we assessed whether genes associated with late-onset Alzheimer's disease (LOAD), inflammation, cholesterol transport, dopamine and myelin regulation, and DNA repair may influence cognitive outcome in this population. METHODS One hundred and fifty brain tumor patients treated with RT ± CT or CT alone completed a neurocognitive assessment and provided a blood sample for genotyping. We genotyped genes/SNPs in these pathways: (i) LOAD risk/inflammation/cholesterol transport, (ii) dopamine regulation, (iii) myelin regulation, (iv) DNA repair, (v) blood-brain barrier disruption, (vi) cell cycle regulation, and (vii) response to oxidative stress. White matter (WM) abnormalities were rated on brain MRIs. RESULTS Multivariable linear regression analysis with Bayesian shrinkage estimation of SNP effects, adjusting for relevant demographic, disease, and treatment variables, indicated strong associations (posterior association summary [PAS] ≥ 0.95) among tests of attention, executive functions, and memory and 33 SNPs in genes involved in: LOAD/inflammation/cholesterol transport (eg, PDE7A, IL-6), dopamine regulation (eg, DRD1, COMT), myelin repair (eg, TCF4), DNA repair (eg, RAD51), cell cycle regulation (eg, SESN1), and response to oxidative stress (eg, GSTP1). The SNPs were not significantly associated with WM abnormalities. CONCLUSION This novel study suggests that polymorphisms in genes involved in aging and inflammation, dopamine, myelin and cell cycle regulation, and DNA repair and response to oxidative stress may be associated with cognitive outcome in patients with brain tumors.

Abstract
Frailty is a complex aging phenotype associated with increased vulnerability to disability and death. Understanding the biological antecedents of frailty may provide clues to healthy aging. The genome-wide association study hotspot, 9p21-23 region, is a risk locus for a number of age-related complex disorders associated with frailty. Hence, we conducted an association study to examine whether variations in 9p21-23 locus plays a role in the pathogenesis of frailty in 637 community-dwelling Ashkenazi Jewish adults aged 65 and older enrolled in the LonGenity study. The strongest association with frailty (adjusted for age and gender) was found with the SNP rs518054 (odds ratio: 1.635, 95% CI = 1.241-2.154; p-value: 4.81 × 10-04) intergenic and located between LOC105375977 and C9orf146. The prevalence of four SNPs (rs1324192, rs7019262, rs518054, and rs571221) risk alleles haplotype in this region was significantly higher (compared with other haplotypes) in frail older adults compared with non-frail older adults (29.7 vs. 20.8%, p = 0.0005, respectively). Functional analyses using in silico approaches placed rs518054 in the CTCF binding site as well as DNase hypersensitive region. Furthermore, rs518054 was found to be in an enhancer site of NFIB gene located downstream. NFIB is a transcription factor that promotes cell differentiation during development, has antiapoptotic effect, maintains stem cell populations in adult tissues, and also acts as epigenetic regulators. Our study found novel association of SNPs in the regulatory region in the 9p21-23 region with the frailty phenotype; signifying the importance of this locus in aging.

Neurobiol Aging 2017; 58:238.e1-238.e8.

Abstract
Motoric cognitive risk (MCR) syndrome is a newly described predementia syndrome characterized by the presence of cognitive complaints and slow gait, which is associated with increased risk of conversion to dementia. The underlying biological mechanisms for MCR have not yet been established. Neuroinflammation mediated through cytokines plays a pivotal role in the pathogenesis of dementia. Hence, our objective was to prospectively examine whether variations in cytokine genes (CRP, IFNG, IL1A, IL1B, IL4, IL6, IL10, IL18, TNF, and IL12A) play a role in MCR incidence in 530 community-dwelling Ashkenazi Jewish adults aged 65 years and older without MCR or dementia at baseline enrolled in the LonGenity study. Over a median follow-up of 2.99 years, 70 participants developed MCR. Single nucleotide polymorphisms (SNPs) in the transcriptional regulatory regions of cytokine IL10, rs1800896 (hazard ratio adjusted for age, gender, and education, aHR: 1.667; 95% CI: 1.198-2.321) and rs3024498 (aHR: 1.926; 95% CI: 1.315-2.822), were associated with incident MCR. Functional analysis using in silico approaches indicated associated SNP rs3024498 "C" allele being the local expression quantitative trait locus. Associated alleles of both the SNPs, rs1800896 and rs3024498, were implicated with overexpression of IL10 gene. None of the variants in the neuroinflammatory pathway studied were associated with incident mild cognitive impairment syndrome. These observations support a role for the IL10 gene in dementia pathogenesis by increasing risk of developing MCR in older adults.

Abstract
Alzheimer's disease (AD) is one of the most common neurodegenerative disorders in the elderly. Although the mechanisms underlying AD neurodegeneration are not fully understood, it is well recognized that inflammation plays a crucial role in the initiation and/or deterioration of AD neurodegeneration. Increasing evidence suggests that different cytokines, including interleukins, TNF-α, TGF-β and IFN-γ, are actively participated in AD pathogenesis and may serve as diagnostic or therapeutic targets for AD neurodegeneration. Here, we review the progress in understanding the important role that these cytokines or neuroinflammation has played in AD etiology and pathogenesis.

Abstract
Alzheimer's disease (AD) has been one of the most prevalent health problems among senior population. Interleukin-1A (IL-1A) and IL-1B are two isoforms of IL-1. Recent studies suggested that certain polymorphisms on these two genes are associated with AD. Bridging integrator 1 (BIN1) is considered as common genetic risk factors for AD, whereas different studies have provided various conclusions regarding its role in AD. This study was designed to justify the association between multiple gene polymorphisms and AD through an evidence synthesis approach. We conducted a literature search to identify relevant articles published from 2000 to 2015 from PubMed, Embase, and Cochrane Library, in accordance with inclusion criteria. Pooled odds ratios (ORs) were calculated for the allele model. The effect estimates were summarized by both standard and cumulative meta-analysis. Finally, 54 articles with 88 independent studies were enrolled in this meta-analysis. Mutants in rs1800587 of IL-1A, rs1143634 of IL-1B, rs12989701, and rs744373 of BIN1 were significantly associated with AD onset. The difference effect of same single nucleotide polymorphisms (SNPs) on various ethnicities was also observed in our results. The present meta-analysis suggested that IL-1A, IL-1B, and BIN1 were candidate genes for AD pathogenesis. Polymorphisms of IL-1A, IL-1B, and BIN1 are associated with AD onset.

Abstract
Objectives Recently, several meta-analyses have reported an association between interleukin (IL) gene polymorphisms and the risk of Alzheimer's disease (AD). Several further papers discussing the relationship with the risk of AD have recently been published. The aim of this meta-analysis was to re-evaluate and update the associations between IL gene polymorphisms and the risk of AD. Methods The search sources were PubMed, Science Direct, Scopus, and Google Scholar up to July 2015, and the following search terms were used: “interleukin 1 or interleukin 6 or interleukin 10” and “variant or polymorphism or SNP” in combination with “Alzheimer's disease”. A meta-analysis using the pooled odds ratios and 95% confidence intervals was carried out to assess the associations between four polymorphisms of IL genes (− 889C > T in IL-1α, − 511C > T in IL-1β, − 174G > C in IL-6 and − 1082G > A in IL-10) and the risk of AD under the heterozygous, homozygous, dominant, and recessive models with fixed- or random-effects models. Results A total of 21,864 cases and 40,321 controls from 93 individual studies were included in this meta-analysis. Our results indicated that the − 889C > T polymorphism was strongly associated with the increased risk of AD. However, three polymorphisms were not associated with the risk of AD. Conclusions Similar to previous meta-analyses, our updated meta-analysis suggested that the − 889C > T polymorphism may be a factor in AD. However, the results of our meta-analysis of the − 174G > C polymorphism differed from those of previous meta-analyses. Consequently, we suggest that the − 174G > C polymorphism may not be a risk factor for AD. 889 C > T polymorphism of IL-1α was significantly associated with increased risk of Alzheimer's disease Three polymorphisms (− 511C > T in IL − 1β, − 174G > C in IL-6 and − 1082G > A in IL-10) were no associated with risk of Alzheimer's disease The results of our meta-analyses for three polymorphisms (− 889C > T, − 511C > T and − 1082G > A) were similar to those previous meta-analyses. However, the results of the − 174G > C polymorphism were different.

Abstract
Interleukin (IL)-1 plays an important role in Alzheimer׳s disease (AD), and single nucleotide polymorphisms (SNPs) in the IL-1 gene have been shown to be associated with AD susceptibility. IL-18 and IL-33 are proinflammatory cytokines of the IL-1 family, and increasing evidence has accumulated to support their crucial role in AD pathogenesis. To examine whether SNPs in IL-1α (rs1800587), IL-1β (rs1143627), IL-18 (rs187238), and IL-33 (rs11792633) are associated with late-onset Alzheimer׳s disease (LOAD) in a Hunan Han Chinese population, we carried out a case-control study involving 201 LOAD patients and 257 healthy controls. No significant differences were found in genotype frequencies of rs1800587 between LOAD patients and controls (P=0.079), but the T allele of rs1800587 was associated with a significantly increased risk of LOAD (P=0.032, odds ratio (OR)=1.592). Significant differences in genotype (P=0.004) and allele (P=0.001) frequencies of rs11792633 were found between LOAD patients and controls, but not for rs1143627 (P=0.535, 0.262, respectively) or rs187238 (P=0.257, 0.139, respectively). The T allele of rs11792633 was found to be a protective factor for LOAD (OR=0.648). These findings suggest that the IL-1α SNP rs1800587 and IL-33 SNP rs11792633, but not the IL-1β SNP rs1143627 or the IL-18 SNP rs187238, contribute to LOAD susceptibility in the Hunan Han Chinese population. This article is part of a Special Issue entitled SI: Brain and Memory.
