Frequency of polymorphisms of signal peptide of TGF-beta1 and -1082G/A SNP at the promoter region of Il-10 gene in patients with carotid stenosis
2006
The role of inflammation in atherosclerosis is well recognized. We have evaluated the allele frequencies of the +869T/C and +915G/C polymorphisms (SNPs) at the TGF-beta1 gene and -1082G/A SNP at IL-10 promoter sequence, two well-known immunosuppressive and anti-inflammatory cytokines, in patients with carotid stenosis. Our data suggest a lack of association between these SNPs and the susceptibility to atherosclerosis although other reports have demonstrated this association. These results may be due to the pleiotropic effects of the cytokines and/or differences in haplotype combination that should be investigated to elucidate the role of TGF-beta1 and IL-10 polymorphisms in atherosclerosis.
Dendritic Cell-Specific Deletion of β-Catenin Results in Fewer Regulatory T-Cells without Exacerbating Autoimmune Collagen-Induced Arthritis.
2015
Dendritic cells (DCs) are professional antigen presenting cells that have the dual ability to stimulate immunity and maintain tolerance. However, the signalling pathways mediating tolerogenic DC function in vivo remain largely unknown. The beta-catenin pathway has been suggested to promote a regulatory DC phenotype. The aim of this study was to unravel the role of beta-catenin signalling to control DC function in the autoimmune collagen-induced arthritis model (CIA). Deletion of beta-catenin specifically in DCs was achieved by crossing conditional knockout mice with a CD11c-Cre transgenic mouse line. Bone marrow-derived DCs (BMDCs) were generated and used to study the maturation profile of …
Characterization of the Adjuvant Effect of IL-12 and Efficacy of IL-12 Inhibitors in Type II Collagen-Induced Arthritis
1996
A destructive joint disease can be induced in susceptible DBA/1 mice by immunization with type II collagen emulsified with oil and either killed Mycobacterium tuberculosis or IL-12 as adjuvant. Cellular and humoral anti-collagen immune mechanisms appear to be involved in the pathogenesis of arthritis. We have characterized the adjuvant effect or IL-12 in more detail and addressed the question whether mycobacteria might act via the induction of endogenous IL-12. Injections of IL-12 into collagen-immunized DBA/1 mice promoted the development of IFN-gamma-producing CD4+ T cells and strongly upregulated the production of complement-fixing IgG2a and IgG2b antibodies resulting in severe arthritis…
Impact of Glucose-Lowering Medications on Cardiometabolic Risk in Type 2 Diabetes
2019
Type 2 Diabetes Mellitus (T2DM) is associated with a high risk of atherosclerotic cardiovascular (CV) disease. Contributing pathophysiologic factors include endothelial dysfunction caused by excessive production of reactive oxygen species (ROS), increased activity of nuclear factor kB (NFkB), altered macrophage polarization, and reduced synthesis of endothelial progenitor cells (EPC). Consequently, there can be a potentially rapid progression of the atherosclerotic disease with a higher propensity to unstable plaque, leading to increased cardiovascular mortality. Management is aimed at prevention, early diagnosis, and treatment of hyperglycemia and vascular complications. Innovative therape…
Heart rate recovery after exercise and maximal oxygen uptake in sedentary patients with type 2 diabetes
2015
Aims: Heart rate recovery after exercise (HRR) is an estimate of autonomic modulation of the heart, and has been shown to be inversely associated with insulin resistance, metabolic syndrome, and type 2 diabetes [1]. Type 2 diabetes is associated with poor exercise tolerance and maximal aerobic capacity (VO2max) [2]. Aim of our study was to assess the relationship between HRR and VO2max in sedentary patients with type 2 diabetes. Methods: Maximal treadmill exercise testing using standard or modified Bruce protocol was performed in 16 (8 males and 8 females) sedentary patients with type 2 diabetes (T2D), and in 16 (9 males and 7 females) age-matched sedentary non-diabetic controls (ND). HRR (…
Pirmā tipa cukura diabēta pacientu klīniskais novērojums endokrinologa praksē: metabolās kompensācijas novērtējums, akūto komplikāciju blakusslimību …
2017
Pētījuma darba galvenais mērķis ir analizēt dažāda smaguma hipoglikēmiju biežumu pirmā tipa cukura diabēta pacientiem un salīdzināt to ar diabēta metabolo kompensāciju. Materiāli un metodes: pētījumā tika analizētas „Latvijas Universitātes Medicīniskās pēcdiploma izglītības institūta” Dr.med. Kristīnes Ducenas pacientu ambulatorās kartes. Tika analizēti pacientu dati ar apstiprinātu diagnozi – pirmā tipa cukura diabēts. Atsevišķi tika apstrādāti dati par pacienta dzimumu, vecumu, cukura diabēta ilgumu (gados), HbA1C līmeni un citām autoimūnām blakussaslimšanām. Atkarībā no HbA1c līmeņa, pētījuma dalībnieki tika sadalīti sekojošās grupās: ●Pirmā grpa- laba diabēta kompensācija (HbA1c 7,5%). …
Heads or Tails? Sandwich-Type Metallocomplexes of Hexakis(2,3-di-O-methyl)-α-cyclodextrin
2020
Native and synthetically modified cyclodextrins (CDs) are useful building blocks in construction of large coordination complexes and porous materials with various applications. Sandwich-type complexes (STCs) are one of the important groups in this area. Usually, coordination of secondary hydroxyls or the “head” portal of native CD molecules to a notional multinuclear ring of metal cations leads to formation of head-to-head STCs. Our study introduces a new CD-ligand, hexakis(2,3-di-O-methyl)-α-cyclodextrin, which enables formation of intriguing head-to-head, but also novel tail-to-tail STCs. Homometallic silver-based head-to-head STCs, AgPF6-STC and AgClO4-STC, were obtained by coordination …
Amplicon-based high-throughput pooled sequencing identifies mutations in CYP7B1 and SPG7 in sporadic spastic paraplegia patients
2011
Hereditary spastic paraplegia (HSP) is a neurodegenerative disorder defined clinically by progressive lower limb spasticity and weakness. HSP is a genetically highly heterogeneous condition with at least 46 gene loci identified so far, involving X-linked, autosomal recessive (AR) and autosomal dominant inheritance. For correct diagnosis, molecular testing is essential because clinical parameters by themselves are not reliable to differentiate HSP forms. The purpose of this study was to establish amplicon-based high-throughput genotyping for AR-HSP. A sample of 187 index cases with apparently sporadic or recessive spastic paraplegia were analyzed by applying an array-based amplification stra…
Atherosclerosis: risk assessment and the role of aiming for optimal glycaemic control in young patients with type 1 diabetes
2023
Wprowadzenie: Dzieci z cukrzycą typu 1 (type 1 diabetes mellitus – DM1) mają w porównaniu ze zdrowymi rówieśnikami podwyższone ryzyko rozwoju zaawansowanej miażdżycy oraz choroby sercowo-naczyniowej (cardiovascular disease – CVD), a niedostateczna kontrola glikemii jest najważniejszym modyfikowalnym czynnikiem ryzyka CVD w DM1. Aktualne metody oceny kontroli glikemii to ocena hemoglobiny glikowanej (HbA1c), samokontrola glikemii za pomocą glukometru (SMBG), a także stosowanie systemów ciągłego monitorowania glukozy (CGM). Do pośredniej oceny ryzyka rozwoju CVD mogą służyć badania rozszerzenia tętnicy w odpowiedzi na niedokrwienie (flow-mediated dilatation – FMD) i prędkości fali tętna (PWV)…
