Multiple sclerosis (MS) is a serious, incurable neurological disease. In 2009, the ANZgene studies detected the suggestive association of located upstream of CD40 gene in chromosome 20q13 (p = 1.3×10(-7)). Identification of the causal variant(s) in the CD40 locus leads to a better understanding of the mechanism underlying the development of autoimmune(More)
Multiple sclerosis (MS) is a multifactorial and polygenic disorder of the central nervous system, its development being under strong influence of T-helpers type I which produce anti-inflammation cytokines. Interleukin 12 (IL12) plays a key role in such polarization of the immune response. Genotyping for polymorphism of the IL12B gene in the 3'-untranslated(More)
A study of parameters of oxidant and antioxidant systems has been carried out in 79 patients with multiple sclerosis (MS) and in 75 mentally and physically healthy subjects. Parameters of intensification of lipids peroxidation and conditions of enzymatic and non-enzymatic parts of antioxidant system (AOS) have been analyzed in different clinical forms and(More)
Dyskinesias are involuntary muscle movements that occur spontaneously in Huntington's disease (HD) and after long-term treatments for Parkinson's disease (levodopa-induced dyskinesia; LID) or for schizophrenia (tardive dyskinesia, TD). Previous studies suggested that dyskinesias in these three conditions originate from different neuronal pathways that(More)
Choline-positive neuroprotectors citicoline and choline alfoscerate decreased blood concentration of protein S100 in clinical trial on 52 patients in the first days after acute ischemic stroke. Neuroprotective therapy has also produced stabilization of blood-brain barrier.
The influence of vinpocetine (cavinton) on endothelium function in 87 patients with chronic cerebral ischemia has been studied. Vinpocetine exerts an endothelium protective effect which appears as a partial renewal of endothelium-dependent vasodilatation and inhibition of rejection of Willebrand factor during arteriovenous occlusion test. Leveling of(More)
Immune mechanisms play a pivotal role in the development of multiple sclerosis (MS). Vitamin D is an important biological immunoregulator acting through receptors of immunocompetent cells. Genotype and haplotype frequencies for VDR polymorphisms in a case-control study of MS have been investigated. Results have shown an association of the VDR T/t variant(More)
A replicative association analysis of Alzheimer’s disease (AD) was carried out for 15 genetic markers that have been associated with cognitive disorders in genome-wide association studies. In the Russian population, AD was associated with CSMD1 rs2616984 (OR = 1.50, 95% CI 1.07–2.09, p-value = 0.018) and, potentially, with NOTCH4 rs313296 (OR = 1.53, 95% CI(More)
Microbiota is a community of microorganisms, viruses, protozoa, colonizing the gut. There are tight phylogenetic relationships between the gut microbiota and the human body, the disturbance of which may lead to the CNS dysfunction as well as to the development of neurodegenerative diseases. This review focuses on general and specific aspects of the(More)
Gut microbiota of patients with Parkinson’s disease and healthy volunteers was analyzed by the method of high throughput 16S rRNA sequencing of bacterial genomes. In patients with Parkinson’s diseases, changes in the content of 9 genera and 15 species of microorganisms were revealed: reduced content of Dorea, Bacteroides, Prevotella, Faecalibacterium,(More)
