Vascular inflammation contributes to the development of many chronic human diseases. Inflammatory stimuli such as interleukin (IL)-1β or disturbed blood flow trigger endothelial activation, thereby promoting leukocyte recruitment and transmigration through inflammatory signaling pathways. This study aimed to identify novel compounds capable of blocking vascular inflammation, with potential therapeutic applications in vascular inflammatory diseases such as atherosclerosis. A natural compound library was screened to identify drug candidates that inhibit IL-1β-induced endothelial inflammation. The anti-inflammatory effects of tigloylgomisin P, one of the hit compounds, were examined in bovine aortic endothelial cells stimulated with IL-1β or oscillatory (disturbed) flow. Endothelial inflammation was assessed by measuring nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) phosphorylation and nuclear translocation, monocyte adhesion to endothelial monolayers, and Smad1/5/9 phosphorylation Tigloylgomisin P suppressed IL-1β-induced NF-κB activation and reduced monocyte adhesion. In addition, it inhibited oscillatory shear stress-induced endothelial inflammation mediated by NF-κB activation and Smad1/5/9 phosphorylation. In ApoE knockout mice, administration of tigloylgomisin P decreased inflammatory marker expression in the atheroprone inner curvature of aortic arches. These findings suggest that tigloylgomisin P may represent a potential therapeutic agent for vascular inflammatory diseases such as atherosclerosis. Show less

Atopic dermatitis (AD) is the most common skin disorder in young children worldwide, with a high impact on morbidity and quality of life. To date, no prospective study has been published on the incidence and potential predictors of AD in South East Asian populations. The Indonesian Prospective Study of Atopic Dermatitis in Infants (ISADI) will address the genetic, metabolic and dietary characteristics of mothers and their offspring, as well as potential determinants of AD within the first year of infant life. This prospective study will be undertaken in about 400 infants to investigate the direct and indirect effects of filaggrin ( The Permanent Medical Research Ethics Committee in Medicine and Health/Faculty of Medicine Universitas Indonesia/Dr Cipto Mangunkusumo Hospital (No. 47/H2.F1/ETIK/2014) approved the study protocol (extended by the letter no. 148/UN2.F1/ETIK/2015). We aim to disseminate our findings via publication in an international journal with high impact factor. Show less
