چکیده

OBJECTIVE We evaluated Toll-like receptors (TLRs) single nucleotide polymorphisms (SNPs) for associations with HIV-1 acquisition, set-point and disease progression in African couples. METHODS Seven candidate and 116 haplotype-tagging SNPs (tagSNPs) were genotyped in 504 HIV-1 infected cases, and 343 seronegative controls. RESULTS TLR9 1635A/G was associated with reduced HIV-1 acquisition among HIV-seronegative controls with high but not low HIV-1 exposure (odds ratio [OR] = 0.7; P = .03 and OR = 0.9, P = .5, respectively). TLR7 rs179012 and TLR2 597C/T reduced set-point; the latter modified by time since HIV-1 acquisition. TLR8 1A/G reduced disease progression. CONCLUSIONS TLR SNPs impact HIV-1 outcomes with epidemiologic factors modifying these relationships.

Toll-like receptor variants are associated with infant HIV-1 acquisition and peak plasma HIV-1 RNA level.

OBJECTIVE We evaluated the association of single nucleotide polymorphisms (SNPs) in TLRs with infant HIV-1 acquisition and viral control. DESIGN Infant HIV-1 outcomes were assessed in a Kenyan perinatal HIV-1 cohort. METHODS Infants were genotyped for six candidate and 118 haplotype-tagging polymorphisms in TLRs 2, 3, 4, 7, 8, and 9, MYD88 and TIRAP. Cox proportional hazards and linear regr...

ارتباط پلی‌مورفیسم‌های ژنتیکی پذیرنده شبه Toll 4 (TLR4) و استعداد ابتلا به سل ریوی

  Background & Aim: Toll-like receptor 2 (TLR2) and Toll-like receptor 4 (TLR4) are the members of the Toll-like receptor family and play important roles in recognition and subsequent immune response against mycobacteria. Two functional polymorphisms for TLR2 (Arg677Trp, C à T Arg753Gln, G à A) and TLR4 (Asp299Gly, A à G Thr399Ile, C à T) genes have been associated with a negative influence on ...

Association of toll-like receptors 2 and 6 polymorphism with clinical mastitis and production traits in Holstein cattle

Mastitis is a costly disease of dairy cattle as it causes a loss in milk yield and milk quality in affected cows. Toll-like receptor (TLR) genes play a role in the host response to a variety of organisms including those inducing mastitis. In the present study, we investigated the polymorphism of TLR2, 4, 6 and 9 genes in Holstein cattle and ...

Effect of Media Use on HIV/AIDS-Related Knowledge and Condom Use in Sub-Saharan Africa: A Cross-Sectional Study

It is known that the level of HIV/AIDS-related knowledge and the degree of condom use varies by socioeconomic status (SES). However, there is limited research on the effect of mass media use on HIV/AIDS-related cognitive and behavioral outcomes in low-income countries and how it might influence the association between SES and HIV-related outcomes. We investigated the moderating effect of media ...

Toll-Like Receptor -1, -2, and -6 Polymorphisms and Pulmonary Tuberculosis Susceptibility: A Systematic Review and Meta-Analysis

BACKGROUND A large number of studies have investigated whether polymorphisms in the Toll-like receptor (TLR) genes are implicated in susceptibility to tuberculosis (TB) in different populations. However, the results are inconsistent and inconclusive. METHODS A literature search was conducted using the PubMed, EMBASE, Medline (Ovid), ISI Web of Knowledge and Chinese National Knowledge Infrastr...
