Oncostatin M-Induced Gene Expression And Regulation In Astrocytes And Microglia, Brandi Janece Baker Jan 2009

Oncostatin M-Induced Gene Expression And Regulation In Astrocytes And Microglia, Brandi Janece Baker

All ETDs from UAB

Astrocytes and microglia are specialized glial cells of the Central Nervous System (CNS) that modulate neural activity and regulate immunological and inflammatory events. These cells perform their functions, in part, through the secretion of soluble mediators such as cytokines and chemokines. However, in response to the same neurological insult or inflammatory stimuli, the responses of these cells can vary greatly. This notion of differential responses was examined in our studies using Oncostatin M (OSM). OSM is a member of the IL-6 family of cytokines, which can be produced by microglia, astrocytes, neurons, and infiltrating leukocytes in the CNS, and is …


Involvement Of Reactive Oxygen Species In The Acute Development Of Insulin Resistance Following Trauma And Hemorrhage, Lidong Zhai Jan 2009

Involvement Of Reactive Oxygen Species In The Acute Development Of Insulin Resistance Following Trauma And Hemorrhage, Lidong Zhai

All ETDs from UAB

Hyperglycemia develops in the intensive care unit in many patients following injury, infection and critical illness. However, little is known about the mechanism of acute development of insulin resistance that causes this hyperglycemia, even though reducing or normalizing the elevated glucose levels has become a major therapeutic target in many ICUs. Using rodent models of injury, acute hepatic insulin resistance occurs within minutes and continues for at least several hours even following fluid resuscitation. We have previously reported that TNF-alpha; is necessary for the hepatic insulin resistance in the rat following resuscitation. However, whether TNF-alpha; plays a role in the …
