Media definitely do matter: Brexit, immigration, climate change and beyond

The notion that the media’s principal role regarding public opinion is reinforcement of pre-existing attitudes – and that this idea is relative inconsequential politically – is pervasive, across many political and social science sub-disciplines, and in non-academic commentary. This article comprehensively challenges the evidential and theoretical underpinnings of this thesis, drawing on a wealth of contemporary survey data and media coverage research, across a range of issues, including climate change, Brexit, immigration, the economy and benefit fraud. It also argues that ‘reinforcement’ is an important and consequential power, and that the processes involved have significant implications for public misperception of salient political issues. It makes the case that the media create attitudinal uncertainty, and can have pervasive but subtle influences on political attitudes, particularly when there are persistent patterns of coverage across a range of media. But also that in contexts like particularly close political contests, such influences can be decidedly consequential

British press attitudes towards the EU's global presence:from the Russian-Georgian War to the 2009 Copenhagen Summit

This article surveys the way in which British print media have presented the European Union (EU)'s global presence in the international arena by analysing two case studies which reflect two very distinctive areas of EU foreign policy: global climate change policy and the policy towards Russia. It employs frame analysis, allowing for the identification of the way in which the discourse of the press was categorized around a series of central opinions and ideas. Frames underscore the connections made by journalists between different events, policies or phenomena and their possible interpretations. The analysis highlights that acting through the common framework of the EU rather than unilaterally was a strategy preferred by the British press. These findings are in stark contrast with the deep Euroscepticism which characterizes press attitudes towards most policy areas, and is often considered to be rooted in the British political culture, media system, public opinion or the longstanding tradition of viewing the European continent as the other

An In Vitro Model of the Glomerular Capillary Wall Using Electrospun Collagen Nanofibres in a Bioartificial Composite Basement Membrane

The filtering unit of the kidney, the glomerulus, contains capillaries whose walls function as a biological sieve, the glomerular filtration barrier. This comprises layers of two specialised cells, glomerular endothelial cells (GEnC) and podocytes, separated by a basement membrane. Glomerular filtration barrier function, and dysfunction in disease, remains incompletely understood, partly due to difficulties in studying the relevant cell types in vitro. We have addressed this by generation of unique conditionally immortalised human GEnC and podocytes. However, because the glomerular filtration barrier functions as a whole, it is necessary to develop three dimensional co-culture models to maximise the benefit of the availability of these cells. Here we have developed the first two tri-layer models of the glomerular capillary wall. The first is based on tissue culture inserts and provides evidence of cell-cell interaction via soluble mediators. In the second model the synthetic support of the tissue culture insert is replaced with a novel composite bioartificial membrane. This consists of a nanofibre membrane containing collagen I, electrospun directly onto a micro-photoelectroformed fine nickel supporting mesh. GEnC and podocytes grew in monolayers on either side of the insert support or the novel membrane to form a tri-layer model recapitulating the human glomerular capillary in vitro. These models will advance the study of both the physiology of normal glomerular filtration and of its disruption in glomerular disease

A Comprehensive Resource of Interacting Protein Regions for Refining Human Transcription Factor Networks

Large-scale data sets of protein-protein interactions (PPIs) are a valuable resource for mapping and analysis of the topological and dynamic features of interactome networks. The currently available large-scale PPI data sets only contain information on interaction partners. The data presented in this study also include the sequences involved in the interactions (i.e., the interacting regions, IRs) suggested to correspond to functional and structural domains. Here we present the first large-scale IR data set obtained using mRNA display for 50 human transcription factors (TFs), including 12 transcription-related proteins. The core data set (966 IRs; 943 PPIs) displays a verification rate of 70%. Analysis of the IR data set revealed the existence of IRs that interact with multiple partners. Furthermore, these IRs were preferentially associated with intrinsic disorder. This finding supports the hypothesis that intrinsically disordered regions play a major role in the dynamics and diversity of TF networks through their ability to structurally adapt to and bind with multiple partners. Accordingly, this domain-based interaction resource represents an important step in refining protein interactions and networks at the domain level and in associating network analysis with biological structure and function

Germline bias dictates cross-serotype reactivity in a common dengue-virus-specific CD8(+) T cell response.

Adaptive immune responses protect against infection with dengue virus (DENV), yet cross-reactivity with distinct serotypes can precipitate life-threatening clinical disease. We found that clonotypes expressing the T cell antigen receptor (TCR) β-chain variable region 11 (TRBV11-2) were 'preferentially' activated and mobilized within immunodominant human-leukocyte-antigen-(HLA)-A*11:01-restricted CD8(+) T cell populations specific for variants of the nonstructural protein epitope NS3133 that characterize the serotypes DENV1, DENV3 and DENV4. In contrast, the NS3133-DENV2-specific repertoire was largely devoid of such TCRs. Structural analysis of a representative TRBV11-2(+) TCR demonstrated that cross-serotype reactivity was governed by unique interplay between the variable antigenic determinant and germline-encoded residues in the second β-chain complementarity-determining region (CDR2β). Extensive mutagenesis studies of three distinct TRBV11-2(+) TCRs further confirmed that antigen recognition was dependent on key contacts between the serotype-defined peptide and discrete residues in the CDR2β loop. Collectively, these data reveal an innate-like mode of epitope recognition with potential implications for the outcome of sequential exposure to heterologous DENVs

Molecular interactions between Hel2 and RNA supporting ribosome-associated quality control

Ribosome-associated quality control (RQC) pathways monitor and respond to stalling of the translating ribosome. Here the authors show that the ribosome associated RQC factor Hel2/ZNF598, an E3 ubiquitin ligase, generally interacts with mRNAs in the vicinity of stop codons
