Forgotten Plotlanders: Learning from the survival of lost informal housing in the UK.

Colin Ward’s discourses on the arcadian landscape of ‘plotlander’ housing are unique documentations of the anarchistic birth, life, and death of the last informal housing communities in the UK. Today the forgotten history of ‘plotlander’ housing documented by Ward can be re-read in the context of both the apparently never-ending ‘housing crisis’ in the UK, and the increasing awareness of the potential value of learning from comparable informal housing from the Global South. This papers observations of a previously unknown and forgotten plotlander site offers a chance to begin a new conversation regarding the positive potential of informal and alternative housing models in the UK and wider Westernised world

CTLA4 is expressed on mature dendritic cells derived from human monocytes and influences their maturation and antigen presentation

<p>Abstract</p> <p>Background</p> <p>Dendritic cells (DCs) initiate immune responses through their direct interaction with effector cells. However, the mechanism by which DC activity is regulated is not well defined. Previous studies have shown that CTLA4 on T cells regulates DCs function by "cross-talk". We investigated whether there is an intrinsic regulatory mechanism in DCs, with CTLA4 as a candidate regulator.</p> <p>Results</p> <p>We confirmed via RT-PCR and flow cytometry the natural expression of CTLA4 on mature DCs derived from human monocytes. Approximately 8% CD1a-positive cells express CTLA4 both on surface and intracellular, whereas 10% CD1a-negative cells express CTLA4 intracellularly, but little expression was observed on the cell surface. The cross-linking of CTLA4 inhibits DCs maturation and antigen presentation in vitro, but does not inhibit endocytosis.</p> <p>Conclusions</p> <p>CTLA4 is expressed by DCs and plays an inhibitory role. CTLA4-expressing DCs may represent a group of regulatory DCs. Because of its wide distribution on different cell types, CTLA4 may play a general role in regulating immune responses.</p

A 'Different Class'? Homophily and Heterophily in the Social Class Networks of Britpop

Social network analysis is increasingly recognised as a useful way to explore music scenes. In this article we examine the individuals who were the cultural workforce that comprised the 'Britpop' music scene of the 1990s. The focus of our analysis is homophily and heterophily to determine whether the clusters of friendships and working relationships of those who were ‘best connected’ in the scene were patterned by original social class position. We find that Britpop's 'whole network' is heterophilic but its 'sub-networks' are more likely to be social class homophilic. The sub-networks that remain heterophilic are likely to be united by other common experiences that brought individuals in the network to the same social spaces. We suggest that our findings on Britpop might be generalised to the composition of other music scenes, cultural workforces and aggregations of young people. Our study differs from research on, first, British ‘indie music’ and social class which focusses upon the construction, representation and performance of social location rather than the relationships it might shape (such as Wiseman-Trowse, 2008) and second, the pioneering social network analyses of music scenes (such as Crossley 2008; 2009; 2015; Crossley et. al 2014) which currently lacks the explicit emphasis on social class

PRIMO: an interactive homology modeling pipeline

The development of automated servers to predict the three-dimensional structure of proteins has seen much progress over the years. These servers make calculations simpler, but largely exclude users from the process. In this study, we present the PRotein Interactive MOdeling (PRIMO) pipeline for homology modeling of protein monomers. The pipeline eases the multi-step modeling process, and reduces the workload required by the user, while still allowing engagement from the user during every step. Default parameters are given for each step, which can either be modified or supplemented with additional external input. PRIMO has been designed for users of varying levels of experience with homology modeling. The pipeline incorporates a user-friendly interface that makes it easy to alter parameters used during modeling

CD200 Receptor Controls Sex-Specific TLR7 Responses to Viral Infection

Immunological checkpoints, such as the inhibitory CD200 receptor (CD200R), play a dual role in balancing the immune system during microbial infection. On the one hand these inhibitory signals prevent excessive immune mediated pathology but on the other hand they may impair clearance of the pathogen. We studied the influence of the inhibitory CD200-CD200R axis on clearance and pathology in two different virus infection models. We find that lack of CD200R signaling strongly enhances type I interferon (IFN) production and viral clearance and improves the outcome of mouse hepatitis corona virus (MHV) infection, particularly in female mice. MHV clearance is known to be dependent on Toll like receptor 7 (TLR7)-mediated type I IFN production and sex differences in TLR7 responses previously have been reported for humans. We therefore hypothesize that CD200R ligation suppresses TLR7 responses and that release of this inhibition enlarges sex differences in TLR7 signaling. This hypothesis is supported by our findings that in vivo administration of synthetic TLR7 ligand leads to enhanced type I IFN production, particularly in female Cd200−/− mice and that CD200R ligation inhibits TLR7 signaling in vitro. In influenza A virus infection we show that viral clearance is determined by sex but not by CD200R signaling. However, absence of CD200R in influenza A virus infection results in enhanced lung neutrophil influx and pathology in females. Thus, CD200-CD200R and sex are host factors that together determine the outcome of viral infection. Our data predict a sex bias in both beneficial and pathological immune responses to virus infection upon therapeutic targeting of CD200-CD200R

The malarial exported PFA0660w is an Hsp40 co-chaperone of PfHsp70-x

Plasmodium falciparum, the human pathogen responsible for the most dangerous malaria infection, survives and develops in mature erythrocytes through the export of proteins needed for remodelling of the host cell. Molecular chaperones of the heat shock protein (Hsp) family are prominent members of the exportome, including a number of Hsp40s and a Hsp70. PFA0660w, a type II Hsp40, has been shown to be exported and possibly form a complex with PfHsp70-x in the infected erythrocyte cytosol. However, the chaperone properties of PFA0660w and its interaction with human and parasite Hsp70s are yet to be investigated. Recombinant PFA0660w was found to exist as a monomer in solution, and was able to significantly stimulate the ATPase activity of PfHsp70-x but not that of a second plasmodial Hsp70 (PfHsp70-1) or a human Hsp70 (HSPA1A), indicating a potential specific functional partnership with PfHsp70-x. Protein binding studies in the presence and absence of ATP suggested that the interaction of PFA0660w with PfHsp70-x most likely represented a co-chaperone/chaperone interaction. Also, PFA0660w alone produced a concentrationdependent suppression of rhodanese aggregation, demonstrating its chaperone properties. Overall, we have provided the first biochemical evidence for the possible role of PFA0660w as a chaperone and as co-chaperone of PfHsp70-x. We propose that these chaperones boost the chaperone power of the infected erythrocyte, enabling successful protein trafficking and folding, and thereby making a fundamental contribution to the pathology of malaria

Untangling creativity and art for policy purposes : ethnographic insights on Manchester International Festival and Manchester Day Parade

This paper draws on anthropological fieldwork of a civic parade in Manchester from 2010 to 2012 to argue for engaging with creativity as a process rather than an attribute of a particular sector or individual. It shows how the focus on funding and supporting ‘creative industries’ defined as ‘cinema, television, music, literature, performing arts, heritage and related areas’ actually excludes and diminishes the potential for others to engage with ideas and creative processes. Two major events in Manchester’s cultural calendar – Procession by artist Jeremy Deller, produced by Manchester International Festival and Manchester Day Parade, a council-led civic celebration – both combined community groups with artist input to put large-scale structures and people on the city’s streets. In this ethnographic analysis, I argue that the ‘creativity’ sought from these artists is their adaptive and productive approach to making ideas tangible. By focusing on creativity as a process rather than a character trait, there is even greater potential for stimulating a ‘creative’ city

Waiting for other people: a psychoanalytic interpretation of the time for action

Typical responses to a confrontation with failures in authority, or what Lacanians term ‘the lack in the Other’, involve attempts to shore it up. A patient undergoing psychoanalysis eventually faces the impossibility of doing this successfully; the Other will always be lacking. This creates a space through which she can reimagine how she might intervene in her suffering. Similarly, when coronavirus forces us to confront the brute fact of the lack in the Other at the socio-political level, we have the opportunity to discover a space for acting rather than continuing symptomatic behaviour that increasingly fails to work

New Labour?new renaissance

This paper explores the term ?urban renaissance? in relation to the historiography of the Renaissance of the 15th and 16th centuries in Italy. It examines the place of the Renaissance in cultural history and considers how it has, since its inception, been utilised by writers to reflect on the present. The paper situates the urban renaissance within the context of New Labour rhetoric at the time of the Millennium. It argues that the idea of renaissance can, in this instance, be connected to a kind of millenarianism that was reflected in public rhetoric regarding the city and in a number of building projects
