The use of biologic therapy has increased over the past decade well beyond primary autoimmune diseases. Indeed, a recent trial using an anti-IL-1beta antibody reduced second myocardial infarction (MI) in those who have had MI. Psoriasis is chronic inflammatory disease often treated with biologics when severe, associated risk MI, part driven by high-risk coronary plaque phenotypes computed tomography angiography (CCTA). We hypothesized that we would observe reduction inflammatory-driven...
Psoriasis is a chronic inflammatory skin disease associated with increased coronary plaque burden and cardiovascular events. Biologic therapy for psoriasis has been found to be favorably luminal plaque, but it unclear whether these associations are attributable direct anti-inflammatory effects on the arteries.To investigate association of biologic inflammation in patients using perivascular fat attenuation index (FAI), novel imaging biomarker that assesses by mapping spatial changes...
BACKGROUND. Systemic lupus erythematosus (SLE) is associated with enhanced risk of atherosclerotic cardiovascular disease not explained by Framingham score (FRS). Immune dysregulation to a distinct subset proinflammatory neutrophils (low density granulocytes; LDGs) may play key roles in conferring CV risk. This study assessed if LDGs are vivo vascular dysfunction and inflammation coronary plaque.
Abstract Increased risk of premature cardiovascular disease (CVD) is well recognized in systemic lupus erythematosus (SLE). Aberrant type I-Interferon (IFN)-neutrophil interactions contribute to this enhanced CVD risk. In animal models, the Janus kinase (JAK) inhibitor tofacitinib improves clinical features, immune dysregulation and vascular dysfunction. We conducted a randomized, double-blind, placebo-controlled trial SLE subjects (ClinicalTrials.gov NCT02535689). study, 30 are randomized...
The insulin-like growth factor (IGF) type 1 receptor is required for growth, transformation, and protection from apoptosis. IGFs can enhance cell migration, which known to be influenced via regulation of the E-cadherin/β-catenin complex. We sought investigate whether IGF-1 modulated interaction between E-cadherin β-catenin in human colorectal cancer cells. used C10 line, we established have previously shown lack adenomatous polyposis coli, E-cadherin, or mutations. found that stimulation...
The type 1 insulin-like growth factor receptor (IGF1R) is often overexpressed by tumors and mediates apoptosis protection. We previously showed that antisense reagents complementary to the IGF1R translation start site enhance radio- chemosensitivity impair Atm function. However these agents induce relatively modest down-regulation affect insulin levels. To identify alternative sites for molecular targeting, we utilized scanning oligonucleotide arrays probe secondary structure of mRNA. This...

Adherens junctions are calcium-dependent cell–cell contacts that link neighboring cells through cadherin receptors. Coordinated regulation of the actin cytoskeleton by Rho GTPases is required for formation and dissolution adherens junctions. However, pathways signaling to cytoskeletal remain poorly defined. Here we identify Abl family kinases as critical mediators cadherin-mediated adhesion. Endogenous kinases, Arg, activated Rac activation after engagement regulate maintenance in mammalian...
Cholesterol efflux capacity (CEC) was recently shown to predict future cardiovascular (CV) events. Psoriasis both increases CV risk and impairs CEC. However, whether having poor CEC is associated with coronary plaque burden currently unknown. We aimed assess the cross-sectional relationship between assessed by quantitative computed tomography angiography (CCTA) in a well-phenotyped psoriasis cohort.
