Innate Immunity As Mediator Of Cell Death And Inflammation In Alcoholic Liver Disease, Arvin Iracheta-Vellve Nov 2017

Innate Immunity As Mediator Of Cell Death And Inflammation In Alcoholic Liver Disease, Arvin Iracheta-Vellve

GSBS Dissertations and Theses

Central driving forces in the pathogenesis of liver disease are hepatocyte death and immune cell-driven inflammation. The interplay between outcomes, stemming from these two major cell types, is present from the earliest ethanol exposure, and are both determinants in advanced stages of liver disease particularly in alcoholic liver disease (ALD). The complexities associated with advanced ALD are many and therapies are limited. Due to the liver’s role in ethanol metabolism and filtering gut-derived products, it is becoming increasingly clear that innate immunity plays a central role in triggering activation of cell death and inflammatory pathways in ALD. We identified ...

Txnip Is A Mediator Of Er Stress-Induced Β-Cell Inflammation And Apoptosis: A Dissertation, Christine M. Oslowski

GSBS Dissertations and Theses

Diabetes mellitus is a group of metabolic disorders characterized by hyperglycemia. The pathogenesis of these diseases involves β-cell dysfunction and death. The primary function of β-cells is to tightly regulate the secretion, production, and storage of insulin in response to blood glucose levels. In order to manage insulin biosynthesis, β-cells have an elaborate endoplasmic reticulum (ER).

The ER is an essential organelle for the proper processing and folding of proteins such as proinsulin. Proteins fold properly when the ER protein load balances with the ER folding capacity that handles this load. Disruption of this ER homeostasis by genetic and environmental ...
