Flat-mount preparations of muscular and …

Targeting Il-6 Signaling And Release Pathways Modulates Inflammation And Restores Intestinal Epithelial Integrity And Function During Mycobacterium Avium Paratuberculosis Infection, Ala' Mahmoud Saleem Alhendi

Graduate Thesis and Dissertation post-2024

Like TNFα, IL-6 is upregulated in Crohn’s disease (CD) associated with Mycobacterium avium paratuberculosis (MAP) infection. Limited therapeutic response to anti-IL-6 therapy may be related to the dual role of IL-6. In this study, we investigated the effects and the signaling mechanism of IL-6 in intestinal epithelial integrity and function during MAP infection using an in vitro model that consists of THP-1, HT-29 and Caco-2 cell lines. Clinically, we determined that plasma samples from MAP-infected CD patients have higher IL-6 levels compared to controls (P-value < 0.001). In CD-like macrophages, MAP infection has significantly upregulated the secretion of IL-6 and the shedding of IL-6 receptor (IL-6R). Moreover, it resulted in significant upregulation of intestinal damage markers including CLDN2, NOX-1 and SERPINE1. Blocking IL-6 signaling exacerbated that damage and enhanced the levels of the damage markers. In HT-29 cells, MAP infection upregulated MUC2 expression, a protective response that was reversed when IL-6R was neutralized. More importantly, blocking IL-6 signaling during MAP infection rescued damaged Caco-2 cells from MAP-induced apoptosis. We also examined the role of monocarboxylate transporter 4 (MCT4), a proton-coupled lactate symporter, that facilitates the inflammatory shift in macrophages, and its impact on intestinal epithelial homeostasis during MAP infection. MAP infection increased lactate export and upregulated the expression of MCT4, TNFα, and IL-6 via TLR2. Inhibition of MCT4 during MAP infection using α-cyano-4-hydroxycinnamic acid (CHCα) significantly reduced TNFα and IL-6 and led to restoring baseline oxidative status, mucin level, and SERPINE1. It also enhanced tight junction protein TJP1 (ZO-1) expression. These findings emphasize the role of IL-6 in MAP-associated CD pathogenesis and explain the ineffective response to IL-6 therapies in CD patients. Moreover, our findings revealed the role of MCT4 in CD pathophysiology during MAP infection and highlighted MCT4 as a potential therapeutic target for effective CD treatment.

Sketching Towards Character: An Actor's Process Of Reclaiming The Mind-Body Connection, Lauren E. Schulke

Graduate Thesis and Dissertation post-2024

The human body is capable of incredible things. It completes vital functions autonomically, can instinctively protect us from harm, helps us sense, process, and respond to the world we inhabit, and can even heal itself when necessary. But what happens when an actor, who is dependent on their body to express their artistry, has lost awareness of their material? With the help of this thesis and the crafting of a personal methodology, I have developed a process that works towards healing this fracture and encourages the initial crafting of character through embodiment.

This thesis details the evolution of a personal …

Criminalizing Ecocide: An Opportunity To Embed The Inseparability Of Humans From Nature Into The Law, Rebecca Hamilton

Scholarly Articles in Law Reviews & Journals

Amid widespread acknowledgment that we live on a planet in peril, the term “ecocide” packs a powerful rhetorical punch. Extant regulatory approaches to environmental protection feel insufficient in the face of the triple threat of climate change, pollution, and biodiversity loss. International criminal prosecution for ecocide, by contrast, promises to meet the moment, and a recent proposal to introduce ecocide into the canon of core international crimes is gaining traction. Assuming the push to criminalize ecocide continues to gain momentum, this Article argues that the primary (and perhaps, sole) benefit that international criminal law can offer in this context is …
