Project description:Baker2013 - Cytokine Mediated Inflammation in
Rheumatoid Arthritis
This model by Baker M. 2013, describes
the interaction between pro and anti-inflammatory cytokine
signalling in rheumatoid arthritis.
Using two ordinary differential equations, the first model
[BIOMD0000000550]
analyses bifurcation and describes different pathological states by
altering inflammatory regulation parameters.
The second model
[BIOMD0000000549]
includes the effect that ageing has on pro-inflammatory signalling,
allowing for time-dependant properties and disease progression to
be observed. The author also describes potential dosing for
reversal of the disease state.

Abstract:
Rheumatoid arthritis (RA) is a chronic inflammatory disease
preferentially affecting the joints and leading, if untreated,
to progressive joint damage and disability. Cytokines, a group
of small inducible proteins, which act as intercellular
messengers, are key regulators of the inflammation that
characterizes RA. They can be classified into pro-inflammatory
and anti-inflammatory groups. Numerous cytokines have been
implicated in the regulation of RA with complex up and down
regulatory interactions. This paper considers a two-variable
model for the interactions between pro-inflammatory and
anti-inflammatory cytokines, and demonstrates that mathematical
modelling may be used to investigate the involvement of
cytokines in the disease process. The model displays a range of
possible behaviours, such as bistability and oscillations,
which are strongly reminiscent of the behaviour of RA e.g.
genetic susceptibility and remitting-relapsing disease. We also
show that the dose regimen as well as the dose level are
important factors in RA treatments.

Project description:Diet can regulate gene and microRNA (miRNA) expression and various biological processes in the gut. Dietary interventions have been proposed as therapeutic approaches for several diseases, including cancer. In a pilot study, we showed that a low-inflammatory Mediterranean diet reduced markers of local and systemic inflammation in 27 patients with Familial Adenomatous Polyposis (FAP). We evaluated the changes induced by a low-inflammatory Mediterranean dietary intervention on fecal miRNome and intestinal tissue transcriptome in FAP subjects and assessed whether these changes could be associated with the beneficial effects observed in the pilot study. The diet modulated 41 fecal miRNAs, and this modulation remained for three months after the intervention. miR-5092-5p, miR-4527, and miR-3612-3p were positively correlated with adherence to the Mediterranean diet, while miR-6867-5p and miR-760-5p were negatively correlated with serum calprotectin levels. The altered miRNAs target genes mainly related to inflammatory pathways, DNA repair, metabolism, and cytoskeleton organization. Seventy genes were differentially expressed between adenoma and normal tissue. Most were different before the dietary intervention, but reached similar levels after the diet. Functional enrichment analysis identified the proinflammatory ERK1/2, cell cycle regulation and nutrient response pathways as commonly regulated by differentially expressed miRNAs and genes. These findings suggest that fecal miRNAs modulated by the diet reflect an epigenetic regulation occurring in tissues that seems to influence inflammatory pathways. miRNAs and genes with oncogenic and tumor suppressor functions are also regulated, highlighting the potential cancer-preventive effect of the low-inflammatory Mediterranean diet.

Project description:Synovial biopsies of Rheumatoid Arthritis patients with active disease were obtained prior to anti-TNF therapy. Clinical response to anti-TNF treatment was measured 20 weeks later using the EULAR response criteria. Gene expression profiles of patients responding to anti-TNF therapy were compared to non-responders and several genes were found to be differentially expressed between both groups of Rheumatoid Arthritis patients.

Project description:objection: The immune inflammatory disorders rheumatoid arthritis (RA), psoriatic arthritis (PsA) and psoriasis (Ps) share common pathologic features and show responsiveness to anti-tumor necrosis factor (TNF) agents yet they are phenotypically distinct. The aim of this study was to examine if anti-TNF therapy is associated with divergent gene expression profiles in circulating cells and target tissues of patients with these diseases Method: Peripheral blood CD14+ and CD14- cells were isolated from 9 RA, 12 PsA and 10 Ps patients before and after infliximab (IFX) treatment. Between April 2007 and June 2009, 31 patients with active RA, PsA and Ps who were naïve to anti-TNF agents, were recruited from the Faculty Rheumatology Clinics at the University of Rochester Medical Center after informed, written consent was obtained in a protocol approved by the Research Subjects Review Board at the University of Rochester Medical Center. Of the 31 subjects, 9 had active RA and 12 had PsA despite treatment with Disease Modifying Anti-Rheumatic Drugs (DMARDs). Also, 10 patients with extensive Ps (>5% BSA) documented by a dermatologist, were enrolled and they were examined by a rheumatologist to exclude the presence of inflammatory arthritis. Nineteen healthy controls were also recruited.

Project description:Objectives: Pinolenic acid (PNLA), an omega-6 polyunsaturated fatty acid from pine nuts, has anti-inflammatory and anti-atherogenic effects. We aimed to investigate the direct anti-inflammatory effect and anti-atherogenic effects of PNLA on activated purified CD14 monocytes from peripheral blood of patients with rheumatoid arthritis (RA) in vitro. Methods: Flow cytometry was used to assess the proportions of CD14 monocytes expressing TNF-α, IL-6, IL-1β, and IL-8 in purified monocytes from patients with RA after lipopolysaccharide (LPS) stimulation with/without PNLA pre-treatment. The whole genomic transcriptome (WGT) profile of PNLA-treated, and LPS-activated monocytes from patients with active RA was investigated by RNA-sequencing. Results: PNLA reduced percentage of monocytes expressing cytokines: TNF-a by 23% (p=0.048), IL-6 by 25% (p=0.011), IL-1B by 23% (p=0.050), IL-8 by 20% (p=0.066). Pathway analysis identified upstream activation of peroxisomes proliferator-activated receptors (PPARs), sirtuin3, and let7miRNA, KLF15 which are anti-inflammatory and antioxidative. In contrast, DAP3, LIF and STAT3, which are involved in TNF-a, and IL-6 signal transduction, were inhibited. Canonical Pathway analysis showed that PNLA inhibited oxidative phosphorylation (p=9.14E-09) and mitochondrial dysfunction (p=4.18E-08), while the sirtuin (SIRTs) signalling pathway was activated (p=8.89E-06) which interfere with the pathophysiologic process of atherosclerosis. Many miRNAs were modulated by PNLA suggesting potential post-transcriptional regulation of metabolic and immune response that has not been described previously. Multiple miRNAs target pyruvate dehydrogenase kinase-4 (PDK4), single-immunoglobulin interleukin-1 receptor molecule (SIGIRR), mitochondrially encoded ATP synthase membrane subunit 6 (MT-ATP6) and Acetyl-CoA Acyltranferase2 (ACAA2); genes implicated in regulation of lipid and cell metabolism, inflammation, and mitochondrial dysfunction. Conclusion: PNLA has potential anti-atherogenic and immune-metabolic effects on monocytes that are pathogenic in RA and atherosclerosis. Dietary PNLA supplementation regulates key miRNAs that are involved in metabolic, mitochondrial, and inflammatory pathways.
