Molecular mechanisms underpinning IFN-gamma and TNF-alpha synergy in intestinal epithelial cells

Cytokine-driven signalling shapes immune homeostasis and guides inflammatory responses mainly through induction of specific gene expression programmes both within and outside the immune cell compartment. These transcriptional outputs are often amplified via cytokine synergy, which sets a stimulatory threshold that safeguards from exacerbated inflammation and immunopathology. In this study, we investigated the molecular mechanisms underpinning synergy between two pivotal Th1 cytokines, IFN-γ and TNF-α, in human intestinal epithelial cells. These two proinflammatory mediators induce a unique state of signalling and transcriptional synergy implicated in processes such as antiviral and antitumour immunity, intestinal barrier and pancreatic β-cell dysfunction. Since its discovery more than 30 years ago, this biological phenomenon remains, however, only partially defined. Here, using a functional genomics approach including RNAi perturbation screens and small-molecule inhibitors, we identified two new regulators of IFN-γ/TNF-α-induced chemokine and antiviral gene and protein expression, a Bcl-2 protein BCL-G and a histone demethylase UTX. We also discovered that IFN-γ/TNF-α synergise to trigger a coordinated shutdown of major receptor tyrosine kinases expression in colon cancer cells. Together, these findings extend our current understanding of how IFN-γ/TNF-α synergy elicits qualitatively and quantitatively distinct outputs in the intestinal epithelium. Given the well-documented role of this synergistic state in immunopathology of various disorders, our results may help to inform the identification of high quality and biologically relevant druggable targets for diseases characterised by an IFN-γ/TNF-α high immune signature

"Ladyes, damesels, and jantilwomen": female autonomy and authority in Sir Thomas Malory's Morte Darthur

Popular medieval English romances were composed and received within the social consciousness of a distinctly patriarchal culture. This study examines the way in which the dynamic of these texts is significantly influenced by the consequences of female endeavour, in the context of an autonomous feminine presence in both the real and imagined worlds of medieval England, and the authority with which this is presented in various narratives, with a particular focus on Sir Thomas Malory’s Morte Darthur. Chapter One of this study establishes the social and economic positioning of the female in fifteenth-century England, and her capacity for literary engagement; I will then apply this model of female autonomy and authority to a wider discussion of texts contemporary with Malory in Chapters Two and Three, in anticipation of a more detailed study of Le Morte Darthur in Chapters Four and Five. My research explores the female presence and influence in these texts according to certain types: namely the lover, the victim, the ruler, and the temptress. In the case of Malory, the crux of my observations centres on the paradox of the capacity for power in perceived vulnerability, incorporating the presentation of women in this patriarchal culture as being vulnerable and in need of protection, while simultaneously acting as a significant threat to chivalric society by manipulating this apparent fragility, to the detriment of the chivalric knight. In this sense, women can be perceived as being an architect of the romance world, while simultaneously acting as its saboteur. In essence, this study offers an innovative interpretation of female autonomy and authority in medieval romance, presenting an exploration of the physical, intellectual, and emotional placement of women in both the historical and literary worlds of fifteenth-century England, while examining the implications of female conduct on Malory’s Arthurian society.

Reading Lydgate's Troy Book: patronage, politics, and history in Lancastrian England

This thesis, Reading Lydgate's Troy Book: Patronage, Politics and History in Lancastrian England, discusses the relationship between John Lydgate as a court poet to his patron Henry V. I contend that the Troy Book is explored as a vehicle to propagate the idea that the House of Lancaster is the legitimate successor to King Richard II in order to smooth over the usurpation of 1399. Paul Strohm's England's Empty Throne was a key influence to the approach of this thesis' topic. I examine that although Chaucer had a definitive impact on Lydgate's writing, Lydgate is able to manipulate this influence for his own ambitions. In order to enhance his own fame, Lydgate works to promote Chaucer's canon so that as Chaucer's successor, he will inherit more prestige. The Trojan war is seen in context with the Hundred Years War, and can be applied contextually to political events. Lydgate presents characters that are vulnerable to human failings, and their assorted, complicated relationships. Lydgate modernises the Troy Book to reflect and enhance his Lancastrian society, and the thesis gives a contextual view of Lydgate's writing of the Troy Book. Lydgate writes for a more varied target audience than his thirteenth-century source, Guido delle Colonne, and there is a deliberation on the female characters of the Troy Book which promulgates the theory that Lydgate takes a proactive and empathetic interest in women's roles in society. Furthermore Lydgate has never really been accepted as a humanist, and I look at Lydgate's work from a different angle; he is a self-germinating humanist. Lydgate revives antiquity to educate his fifteenth-century audience, and his ambition is to create a memorial for his patron in the vernacular, and enhance his own fame as a poet separate from Chaucer's shadow.
