Development, Expansion And Role Of Myeloid-Derived Suppressor Cells In Post-Sepsis Immune Suppression, Tuqa Alkhateeb
Development, Expansion And Role Of Myeloid-Derived Suppressor Cells In Post-Sepsis Immune Suppression, Tuqa Alkhateeb
Electronic Theses and Dissertations
Myeloid-derived suppressor cells (MDSCs) numbers increase significantly in sepsis and are associated with high mortality rates. These myeloid cell precursors promote immunosuppression, especially in the late (post sepsis) stage. However, the mechanisms that underlie MDSC expansion and programming are not completely understood. To investigate these mechanisms, we used a cecal-ligation and puncture (CLP) mouse model of polymicrobial sepsis that progresses from an early/acute proinflammatory phase to a late/chronic immunosuppressive phase. Previous studies in our laboratory showed that microRNA (miR)-21 and miR-181b elevate levels of the transcription factor nuclear factor 1 (NFI-A) that promotes MDSC expansion. We report here that miR-21 …
Social Aspects Of Food-Sensitive Adults, Jean Elizabeth Duane
Social Aspects Of Food-Sensitive Adults, Jean Elizabeth Duane
Electronic Theses and Dissertations
People living with food-related illnesses find themselves subjugated by commonly held ideologies causing awkwardness in social situations. The current study is a qualitative analysis addressing how people with celiac disease (CD) navigate social situations in light of dominant beliefs that influence behaviors. Initially, I identify macro-level patriarchal, religious, sexist, ableist and etiquette-related commensality ideologies that disadvantage those with CD. Drawing from the communication narrative sense making (CNSM) theory that supports storytelling and memorable messages as a sense-making tool for individuals diagnosed with chronic illness and their family members, this work highlights retrospective stories and memorable messages from 20 randomly selected …
Monitoring Pollen Counts And Pollen Allergy Index Using Satellite Observations In East Coast Of The United States, Murat Cagatay Kececi
Monitoring Pollen Counts And Pollen Allergy Index Using Satellite Observations In East Coast Of The United States, Murat Cagatay Kececi
Electronic Theses and Dissertations
Allergic diseases have become increasingly common over the world during the last four decades, and they are affecting millions of people. Pollination is an important process in the life cycle of plants. However, pollen exposure is associated with allergic diseases such as asthma and seasonal allergic rhinitis (hay fever). As a result, the total annual expenditure for asthma-associated morbidity is about $56 billion in the United States, and the overall cost of allergic diseases is over $18 billion annually. For allergic rhinitis, the annual medical cost is approximately $3.4 billion. The intensity and frequency of the pollen exposures can be …

Sa-4-1bbl As A Modulator Of Innate, Adaptive, And Regulatory Immunity : Implications For Cancer Prevention And Treatment., Hampartsoum Barsoumian
Electronic Theses and Dissertations
SA-4-1BBL is a recombinant costimulatory molecule that is active in its soluble form and has pleiotropic effects on the functions of innate, adaptive, and regulatory immune cells. We have previously shown that SA-4-1BBL makes CD4+ T conventional cells (Tconvs) resistant to suppression by CD4+CD25+Foxp3+ T regulatory cells (Tregs). The mechanistic basis of this observation is the subject of this study. We demonstrate that Tconvs, but not Tregs, are the direct targets of SA-4-1BBL-mediated evasion of Treg suppression without contribution from antigen presenting cells (APCs). SA-4-1BBL engagement with its receptor, 4-1BB, on Tconvs resulted in the production of high levels of …
