The human gut is colonized by a wide diversity of micro-organisms, which are now known to play a key role in the human host by regulating metabolic functions and immune homeostasis. Many studies have indicated that the genomes of our gut microbiota, known as the gut microbiome or our "other genome" could play an important role in immune-related, complex(More)
RATIONALE Evidence suggests that the gut microbiome is involved in the development of cardiovascular disease, with the host-microbe interaction regulating immune and metabolic pathways. However, there was no firm evidence for associations between microbiota and metabolic risk factors for cardiovascular disease from large-scale studies in humans. In(More)
Deep sequencing of the gut microbiomes of 1135 participants from a Dutch population-based cohort shows relations between the microbiome and 126 exogenous and intrinsic host factors, including 31 intrinsic factors, 12 diseases, 19 drug groups, 4 smoking categories, and 60 dietary factors. These factors collectively explain 18.7% of the variation seen in the(More)
OBJECTIVE Signal-transducer and activator of transcription protein 3 (STAT3) gene encodes a transducer and transcription factor that plays an important role in many cellular processes such as cell growth, apoptosis and immune response. Several STAT3 genetic variants have been associated to different autoimmune diseases. Our aim was to reveal the possible(More)
The gut microbiome is affected by multiple factors, including genetics. In this study, we assessed the influence of host genetics on microbial species, pathways and gene ontology categories, on the basis of metagenomic sequencing in 1,514 subjects. In a genome-wide analysis, we identified associations of 9 loci with microbial taxonomies and 33 loci with(More)
Although the etiology of multiple sclerosis (MS) is unknown, it is generally believed that genetic, immunologic, and environmental factors are involved. The objectives of this study were: 1. to analyze if a genetic control could explain why HHV-6 would be able to actively replicate in a subset of MS patients but not in controls; 2. to study if MS patients(More)
In recent reports, IRF5 polymorphisms showed significant association with multiple sclerosis (MS) susceptibility in three studied populations and Irf5-deficient mice exhibited an increased susceptibility to viral infection, linked to a significant decrease in the induction of serum type I interferon (IFN). In the present study, we evaluated the association(More)
BACKGROUND Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. Interferon-beta is the most usual therapy in relapsing-remiting MS. However, approximately 50% of the treated patients do not respond adequately. Very recently, a genome-wide association study on interferon-beta pharmacogenetics has described polymorphisms at(More)
OBJECTIVE The STAT4 gene encodes a transcription factor involved in the signaling pathways of several cytokines, including interleukin-12 (IL-12), the type I interferons, and IL-23. Recently, the association of a STAT4 haplotype marked by rs7574865 with rheumatoid arthritis (RA) and systemic lupus erythematosus was reported. The aim of this study was to(More)
Genome-wide association studies (GWAS) have revealed that different diseases share susceptibility variants. Twelve single-nucleotide polymorphisms (SNPs) previously associated with different immune-mediated diseases in GWAS were genotyped in a Caucasian Spanish population of 2864 multiple sclerosis (MS) patients and 2930 controls. Three SNPs were found to(More)
