Irregular Migration, Trafficking and Smuggling of Human Beings: Policy Dilemmas in the EU. CEPS Paperback, 22 February 2016

The expert contributors to this edited volume, representing a multidisciplinary selection of academics, examine the treatment of irregular migration, human trafficking and smuggling in EU law and policy. The various chapters explore the policy dilemmas encountered in efforts to criminalise irregular migration and humanitarian assistance to irregular immigrants. The book aims to provide academic input to informed policy-making in the next phase of the European Agenda on Migration. In his Foreword, Matthias Ruete, Director General of DG Home Affairs of the European Commission, writes: “This initiative aims to stimulate evidence-based policy-making and to bring fresh thinking to develop more effective policies. The European Commission welcomes the valuable contribution of this initiative to help close the wide gap in our knowledge about the smuggling of migrants, and especially the functioning of smuggling networks.”

Facilitating Mobility and Fostering Diversity: Getting EU Migration Governance to Respect the Human Rights of Migrants. CEPS Paper in Liberty and Security in Europe No. 92/May 2016

Migration towards Europe has surged over the past few years, overwhelming government authorities at the national and EU levels, and fuelling a xenophobic, nationalist, populist discourse linking migrants to security threats. Despite positive advances in the courts and worthy national initiatives (such as Italy’s Operation Mare Nostrum), the EU’s governance of migration and borders has had disastrous effects on the human rights of migrants. These effects stem from the criminalisation of migrants, which pushes them towards more precarious migration routes, the widespread use of administrative detention and the processing of asylum claims under the Dublin system, and now the EU–Turkey agreement. Yet, this paper finds that with the right political leadership, the EU could adopt different policies in order to develop and implement a human rights-based approach to migration that would seek to reconcile security concerns with the human rights of migrants. Such an approach would enable member states to fully reap the rewards of a stable, cohesive, long-term migration plan that facilitates and governs mobility rather than restricts it at immense cost to the EU, the member states and individual migrants.

Trade Policy, Investment and Migration: The Liberalisation Paradigm

Presentation by Thomas Cottier & Charlotte Sieber-Gasser prepared for the Markets for Migration and Development (M4MD) Conference, Bern, 13-15 September 2011. This presentation is part of Session 1 "Why Trade, Development and Migration?" of the M4MD conference, which was one of the thematic meetings held in the context of the 2011 Global Forum on Migration and Development (GFMD) chaired by Switzerland. Session 1 seeked to understand to what extent international trade and foreign direct investment drives migration and why states find it more difficult to liberalise the trans‐boundary movement of persons than to liberalise cross‐border trade in goods and services. One discussed aspect was why globalisation, trade liberalisation and FDI can lead not only to more, but also to less migration and what the corresponding effects on development would be. This Session provided a timely opportunity to broaden the perspective on international migration and explore the interaction between migration, development and trade policymaking.

Youth, Religion and Participation : Theoretical and Methodological Approaches

This roundtable session focus on religious and social change as well as democracy and political culture, startingfrom the role of youth in these processes. The role of religion in young people’s participation is a key theme inthe cross-disciplinary network “youth and religion” connected to the Impact program. Participation here includesboth citizens’ “vertical” capacities to make their voices heard and influence decision-makers in the political system(e.g. via elections or civic organizations and social movements) and their “horizontal” capacities to communicateand cooperate with other people (within society at large or certain associations/communities). The participants ofthe session will present influential theories and methodologies used to study participation among youth within theresearch disciplines they represent (i.e. sociology of religion; theology; ethnology; political science). This will befollowed by a joint discussion of how these theories and methodologies have approached religious involvement witha particular focus on youth’s participation in politics, civil society as well as social media and the internet. The aim ofthe session is to look for common themes and new issues that can guide contemporary studies of participation in thefield of youth and religion. The session is open to conference participants interested in the issues discussed.

S100P dissociates myosin IIA filaments and focal adhesion sites to reduce cell adhesion and enhance cell migration

S100 proteins promote cancer cell migration and metastasis. To investigate their roles in the process of migration we have constructed inducible systems for S100P in rat mammary and human HeLa cells that show a linear relationship between its intracellular levels and cell migration. S100P, like S100A4, differentially interacts with the isoforms of nonmuscle myosin II (NMIIA, K(d) = 0.5 µm; IIB, K(d) = 8 µm; IIC, K(d) = 1.0 µm). Accordingly, S100P dissociates NMIIA and IIC filaments but not IIB in vitro. NMIIA knockdown increases migration in non-induced cells and there is no further increase upon induction of S100P, whereas NMIIB knockdown reduces cell migration whether or not S100P is induced. NMIIC knockdown does not affect S100P-enhanced cell migration. Further study shows that NMIIA physically interacts with S100P in living cells. In the cytoplasm, S100P occurs in discrete nodules along NMIIA-containing filaments. Induction of S100P causes more peripheral distribution of NMIIA filaments. This change is paralleled by a significant drop in vinculin-containing, actin-terminating focal adhesion sites (FAS) per cell. The induction of S100P, consequently, causes significant reduction in cellular adhesion. Addition of a focal adhesion kinase (FAK) inhibitor reduces disassembly of FAS and thereby suppresses S100P-enhanced cell migration. In conclusion, this work has demonstrated a mechanism whereby the S100P-induced dissociation of NMIIA filaments leads to a weakening of FAS, reduced cell adhesion, and enhanced cell migration, the first major step in the metastatic cascade.

Joining S100 proteins and migration:for better or for worse, in sickness and in health

The vast diversity of S100 proteins has demonstrated a multitude of biological correlations with cell growth, cell differentiation and cell survival in numerous physiological and pathological conditions in all cells of the body. This review summarises some of the reported regulatory functions of S100 proteins (namely S100A1, S100A2, S100A4, S100A6, S100A7, S100A8/S100A9, S100A10, S100A11, S100A12, S100B and S100P) on cellular migration and invasion, established in both culture and animal model systems and the possible mechanisms that have been proposed to be responsible. These mechanisms involve intracellular events and components of the cytoskeletal organisation (actin/myosin filaments, intermediate filaments and microtubules) as well as extracellular signalling at different cell surface receptors (RAGE and integrins). Finally, we shall attempt to demonstrate how aberrant expression of the S100 proteins may lead to pathological events and human disorders and furthermore provide a rationale to possibly explain why the expression of some of the S100 proteins (mainly S100A4 and S100P) has led to conflicting results on motility, depending on the cells used. © 2013 Springer Basel.

Human intervertebral disc aggrecan inhibits endothelial cell adhesion and cell migration in vitro

STUDY DESIGN: The effect of human intervertebral disc aggrecan on endothelial cell growth was examined using cell culture assays. OBJECTIVE: To determine the response of endothelial cells to human intervertebral disc aggrecan, and whether the amount and type of aggrecan present in the intervertebral disc may be implicated in disc vascularization. SUMMARY OF BACKGROUND DATA: Intervertebral disc degeneration has been associated with a loss of proteoglycan, and the ingrowth of blood vessels and nerves. Neovascularization is a common feature also of disc herniation. Intervertebral disc aggrecan is inhibitory to sensory nerve growth, but the effects of disc aggrecan on endothelial cell growth are not known. METHODS: Aggrecan monomers were isolated separately from the anulus fibrosus and nucleus pulposus of human lumbar intervertebral discs, and characterized to determine the amount and type of sulfated glycosaminoglycan side chains present. The effects of these aggrecan isolates on the cellular adhesion and migration of the human endothelial cell lines, HMEC-1 and EAhy-926, were examined in vitro. RESULTS: Homogenous substrata of disc aggrecan inhibited endothelial cell adhesion and cell spreading in a concentration dependent manner. In substrata choice assays, endothelial cells seeded onto collagen type I migrated over the collagen until they encountered substrata of disc aggrecan, where they either stopped migrating, retreated onto the collagen, or, more commonly, changed direction to align along the collagen-aggrecan border. The inhibitory effect of aggrecan on endothelial cell migration was concentration dependent, and reduced by enzymatic treatment of the aggrecan monomers with a combination of chondroitinase ABC and keratinase/keratinase II. Anulus fibrosus aggrecan was more inhibitory to endothelial cell adhesion than nucleus pulposus aggrecan. However, this difference did not relate to the extent to which the different aggrecan isolates were charged, as determined by colorimetric assay with 1,9-dimethylmethylene blue, or to marked differences in the distribution of chondroitin sulfated and keratan sulfated side chains. CONCLUSIONS: Human intervertebral disc aggrecan is inhibitory to endothelial cell migration, and this inhibitory effect appears to depend, in part, on the presence of glycosaminoglycan side chains on the aggrecan monomer.

Angiopoietin-1 induces migration of monocytes in a tie-2 and integrin-independent manner

Angiopoietin-1 (Ang-1) is an angiogenic growth factor that activates Tie-2 and integrins to promote vessel wall remodeling. The recent finding of the potential proatherogenic effects of Ang-1 prompted us to investigate whether Ang-1 promotes monocyte chemotaxis, endothelial binding, and transendothelial migration, key events in the progression of atherosclerosis. Here, we show that Ang-1 induces chemotaxis of monocytes in a manner that is independent of Tie-2 and integrin binding but dependent on phosphoinositide 3-kinase and heparin. In addition, Ang-1 promoted phosphoinositide 3-kinase-dependent binding of monocytes to endothelial monolayers and stimulated transendothelial migration. Fluorescence-activated cell sorting analysis showed that exogenous Ang-1 adheres directly to monocytes as well as to human umbilical endothelial cells, but neither Tie-2 mRNA nor protein were expressed by primary monocytes. Although Ang-1 binding to human umbilical endothelial cells was partially Tie-2 and integrin dependent, Ang-1 binding to monocytes was independent of these factors. Finally, preincubation of monocytes with soluble heparin abrogated Ang-1 binding to monocytes and migration, and partially prevented Ang-1 binding to human umbilical endothelial cells. In summary, Ang-1 induces chemotaxis of monocytes by a mechanism that is dependent on phosphoinositide 3-kinase and heparin but independent of Tie-2 and integrins. The ability of Ang-1 to recruit monocytes suggests it may play a role in inflammatory angiogenesis and may promote atherosclerosis.
