Tetramerization Of Stat5 Has Opposing Roles In Governing Autoimmune Pathogenesis, Kelly Lynn Monaghan Jan 2022

Tetramerization Of Stat5 Has Opposing Roles In Governing Autoimmune Pathogenesis, Kelly Lynn Monaghan

Graduate Theses, Dissertations, and Problem Reports

Signal transducers and activators of transcription 5 (STAT5A and STAT5B) are members of the STAT protein family. STAT5 plays a critical role in mediating cellular responses following cytokine stimulation. Critical STAT5 signaling is achieved following functional dimerization, which occurs via SH2 domain interactions. The binding of two STAT5 dimers to tandemly linked TTCN3GAA γ-interferon-activated sequence (GAS) motifs and N-terminal domain interactions, facilitates functional tetramerization. The biological role of STAT5 tetramers has been investigated using the Stat5a-Stat5b N-domain double knock-in (DKI) mouse strain, in which STAT5 tetramers cannot be formed due to substitutions in critical amino acid …


Utilizing The K18-Hace2 Mouse Model To Develop Protective Covid-19 Vaccines, Ting Y. Wong Jan 2022

Utilizing The K18-Hace2 Mouse Model To Develop Protective Covid-19 Vaccines, Ting Y. Wong

Graduate Theses, Dissertations, and Problem Reports

The ongoing Coronavirus Disease 2019 (COVID-19) pandemic is caused by the respiratory virus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Similar to other respiratory viruses, SARS-CoV-2 is transmitted through inhalation of respiratory droplets and aerosols from infected individuals. Once inhaled, SARS-CoV-2 utilizes the receptor binding domain (RBD) on the spike protein to bind to human Angiotensin Converting Enzyme 2 (hACE2) receptor to gain entrance into host cells to begin viral replication. SARS-CoV-2 infection can result in mild to severe cases of COVID-19 ranging from asymptomatic infections, cold or flu like symptoms to respiratory failure. The onset of the pandemic in …


Investigating The Interplay Of The Immune System, Skin Barrier, And Microbiome Following Dermal Exposure To Triclosan, Rachel Baur Jan 2022

Investigating The Interplay Of The Immune System, Skin Barrier, And Microbiome Following Dermal Exposure To Triclosan, Rachel Baur

Graduate Theses, Dissertations, and Problem Reports

Triclosan is an antimicrobial chemical used in healthcare products that are applied to the skin. However, exposure to triclosan has been positively associated with food allergy, aeroallergy, and asthma severity in humans. In mice, dermal triclosan exposure, although not directly sensitizing, has been shown to augment the allergic response in a model of asthma. Furthermore, exposure to triclosan on mouse skin has been demonstrated to be immunomodulatory through the activity of thymic stromal lymphopoietin and S100 calcium-binding protein A8. The skin barrier and microbiome are known to interact with the immune system and disruptions in barrier integrity and the microbiome …
