'We always come here': investigating the social in social learning
No full textThis paper investigates student choices around the 'Third Space' for learning; that which is not either a teaching space or a private space. In mapping the use of such spaces around the University of Northampton's campuses and through the use of semi-structured interviews with students as they use the spaces it constructs a model to help understand why students choose a particular space to work in and influence decisions in the deliberate creation of such spaces in future.
The research shows four, often overlapping, influences on student choice of space; resources, environment, social and emotional. That resource rich spaces that allow social interaction and learning to take place in attractive environments are popular should not be surprising but it is the emotional response to space that is of particular interest. Space attachment theory has usually centred on home or places with religious or national symbolism. This paper identifies an element of emotional resonance to areas of the university campus, especially the library, that will warrant further research

Characterization of the ERp57-Tapasin complex by rapid cellular acidification and thiol modification
No full textMajor histocompatibility complex (MHC) class I molecules bind and present short peptides to cells of the immune system. The oxidoreductase ERp57 is involved in the assembly of MHC class I molecules and is a component of the peptide loading complex, where it is found disulfide-bonded to tapasin. We have studied ERp57 and the ERp57-tapasin conjugate by rapid acidification of the intracellular environment with trichloroacetic acid (TCA), followed by thiol modification with the alkylating agent 4'-maleimidylstilbene-2,2'-disulfonic acid (AMS). By using TCA/AMS treatment, non-tapasin-associated ERp57 is shown to exist almost exclusively in a reduced state, suggesting that both thioredoxin-like CXXC motifs are exposed and reduced. A 110-kDa product is readily detected with this TCA/AMS protocol and is confirmed as an ERp57-tapasin conjugate by its absence from the tapasin-deficient .220 cell line and by immunoblotting with both ERp57- and tapasin-specific antisera. The ERp57-tapasin conjugate can also be modified with the oxidizing agent diamide, indicating that within the pool of ERp57-tapasin complexes the free, non-tapasin-linked CXXC motif exists in both oxidized and reduced states, suggesting availability to undergo redox reactions

Assembly and export of MHC class I peptide ligands
No full textDuring the assembly of MHC class I molecules with peptide, a series of transient interactions are made with endoplasmic reticulum-resident chaperones and MHC class I-specific accessory molecules. These interactions culminate in the trafficking of MHC class I molecules to the cell surface and presentation of peptide to CD8+ T lymphocytes. Recent studies have revealed just how important these early interactions are, and how they influence the quality control of assembly and the optimisation of peptide–ligand binding
Competition for access to the rat major histocompatibility complex class I peptide-loading complex reveals optimization of peptide cargo in the absence of transporter associated with antigen processing (TAP) association
No full textMajor histocompatibility complex (MHC) class I molecules load peptides in the endoplasmic reticulum in a process during which the peptide cargo is normally optimized in favor of stable MHC-peptide interactions. A dynamic multimolecular assembly termed the peptide-loading complex (PLC) participates in this process and is composed of MHC class I molecules, calreticulin, ERp57, and tapasin bound to the transporter associated with antigen processing (TAP) peptide transporter. We have exploited the observation that the rat MHC class I allele RT1-Aa, when expressed in the rat C58 thymoma cell line, effectively competes and prevents the endogenous RT1-Au molecule from associating with TAP. However, stable RT1-Au molecules are assembled efficiently in competition with RT1-Aa, demonstrating that cargo optimization can occur in the absence of TAP association. Defined mutants of RT1-Aa, which do not allow formation of the PLC, fail to become thermostable in C58 cells. Wild-type RT1-Aa, which does allow PLC formation, also fails to become thermostable in this cell line, which carries the rat TAPB transporter that supplies peptides incompatible for RT1-Aa binding. Full optimization of RT1-Aa requires the presence of the TAP2A allele, which is capable of supplying suitable peptides. Thus, formation of the PLC alone is not sufficient for optimization of the MHC class I peptide carg
