    Abstract Inflammatory bowel disease (IBD) is a lifelong inflammatory immune mediated disorder, encompassing Crohn’s disease (CD) and ulcerative colitis (UC); however, the cause and specific pathogenesis of IBD is yet incompletely understood. Multiple cytokines produced by different immune cell types results in complex functional networks that constitute a highly regulated messaging network of signaling pathways. Applying biological mechanisms underlying IBD at the single omic level, technologies and genetic engineering enable the quantification of the pattern of released cytokines and new insights into the cytokine landscape of IBD. We focus on the existing literature dealing with the biology of pro- or anti-inflammatory cytokines and interactions that facilitate cell-based modulation of the immune system for IBD inflammation. We summarize the main roles of substantial cytokines in IBD related to homeostatic tissue functions and the remodeling of cytokine networks in IBD, which may be specifically valuable for successful cytokine-targeted therapies via marketed products. Cytokines and their receptors are validated targets for multiple therapeutic areas, we review the current strategies for therapeutic intervention and developing cytokine-targeted therapies. New biologics have shown efficacy in the last few decades for the management of IBD; unfortunately, many patients are nonresponsive or develop therapy resistance over time, creating a need for novel therapeutics. Thus, the treatment options for IBD beyond the immune-modifying anti-TNF agents or combination therapies are expanding rapidly. Further studies are needed to fully understand the immune response, networks of cytokines, and the direct pathogenetic relevance regarding individually tailored, safe and efficient targeted-biotherapeutics.

Here authors engineer human orphan GPCRs to be activated by light which allows studying the receptors ligand identity and downstream signaling.

    Abstract Aim: Patients with inflammatory bowel disease (IBD) are prone to cardiovascular disorders, although there is little research to support this assertion, and other data are controversial in children. We aimed to determine the extent of premature atherosclerosis in Crohn's disease (CD) by measuring reactive hyperaemia index (RHI) as a functional marker of endothelial dysfunction (ED).
    Methods: Twenty-one patients with CD and twelve healthy matched subjects were enrolled in the study. Diagnosis was based on the standard clinical, endoscopic and histological criteria, including the Paediatric Crohn's disease Activity Index. ED was assessed using the plethysmographic RHI, combined with specific biochemical markers of ED.
    Result: RHI values were significantly lower in the patients with CD than the controls (p < 0.05). E-selectin (p < 0.05), asymmetric dimethylarginine (p < 0.01) and high-sensitive CRP (p < 0.05), but not vascular cells adhesive molecule-1 values, were significantly increased in the CD subjects compared with the control group.
    Conclusion: Significantly decreased RHI and elevated plasma levels of specific biochemical parameters seems to be related to systemic inflammation and ED in children with CD. Our results support the hypothesis regarding RHI and ED in paediatric CD. This combined method assessment might be a useful tool for detection of ED and stratification of cardiovascular risk in patients with CD.

    Abstract A Well-Defined Path Although chemokines have long been thought to direct immune cell movements within tissues, a formal in vivo demonstration and detailed understanding are lacking. By tracking dendritic cell movements in the ears of mice, Weber et al. (p. 328) were able to provide both. Endogenous gradients of the chemokine CCL21 were observed in ear tissue and, at distances of up 90 µm, dendritic cells were able to use these gradients to migrate directionally toward lymphatic vessels. The CCL21 gradient was immobilized on heparan sulfates and disruption of the gradient inhibited dendritic cell migration.
