Functional Significance Of Endothelial Sigma-1 Receptors In Vascular Reactivity And Barrier Function, Zeinab Y. Motawe

USF Tampa Graduate Theses and Dissertations

The sigma-1 receptor (σ1) is a single 25 kD polypeptide that acts as a chaperone protein residing primarily in the endoplasmic reticulum Its interaction with mitochondria at the mitochondria-associated ER membrane domain is well-documented. Following activation, σ1 binds to the inositol trisphosphate receptor (Hayashi & Su), and modulates intracellular calcium homeostasis. Also, the activated σ1 modulates plasma membrane receptors and ion channel functions, and may regulate cellular excitability. Further, σ1 affects trafficking of lipids and proteins essential for neurotransmission, cell growth and motility. Activation of σ1 provides neuroprotection and cardio-protection in various models. Examples of neuroprotection include but not limited …

The Location Of Sensing Determines The Pancreatic Β-Cell Response To The Viral Mimetic Dsrna, Zachary R. Shaheen, Joshua D. Stafford, Michael G. Voss, Bryndon J. Oleson, Jennifer S. Stancill, John A. Corbett

Biological Sciences Faculty Research & Creative Works

Viral infection is an environmental trigger that has been suggested to initiate pancreatic β-cell damage, leading to the development of autoimmune diabetes. Viruses potently activate the immune system and can damage β-cells by either directly infecting them or stimulating the production of secondary effector molecules (such as proinflammatory cytokines) during bystander activation. However, how and where β-cells recognize viruses is unclear, and the antiviral responses that are initiated following virus recognition are incompletely understood. In this study, we show that the β-cell response to dsRNA, a viral replication intermediate known to activate antiviral responses, is determined by the cellular location …

A&P Workshop Summary—Uniting Anatomy And Physiology Through Case Studies, Angela Horner, Stuart Sumida, Tomasz Owercowicz

Q2S Enhancing Pedagogy

Introducing problem-solving based methods of pedagogy is one approach to engage students early in their careers with developing analytic and diagnostic skills. PBL approaches in anatomy and medical teaching are a logical extension of clinical case studies, wherein an example of a pathology or clinical procedure is provided, and students must ascertain the anatomical and/or physiological basis for it. Students report a deeper understanding of material presented in clinical case studies, as the ‘real world’ relevance and importance is immediately clear (Cliff and Wright, 1996).
