Antimicrobial Peptide Development: From Massively Parallel Peptide Sequencing To Bioinformatic Motif Identification, Alexander K. Erikson Dec 2020

Antimicrobial Peptide Development: From Massively Parallel Peptide Sequencing To Bioinformatic Motif Identification, Alexander K. Erikson

Theses and Dissertations

The isolation, purification, and clinical deployment of antibiotics is one of the major drivers of decrease in morbidity and mortality from infectious bacteria in the 20th century. The rapid, ubiquitous deployment of antibiotics encouraged swift development and distribution of antibiotic resistance. New, novel techniques, technologies, and ultimately therapeutic antimicrobial compounds will be required to counter the rise of antibiotic resistant microbes. Historically, mimicking naturally occurring compounds has been the most fruitful method for discovering new antibiotics; unsurprisingly, many recent efforts have focused on expanding the cultivation and detection of previously unknown microbes and compounds, respectively. Other techniques explore developing compounds …


Dual Role Of Antimicrobial Peptide Cathelicidin In Alcohol-Associated Liver Disease., Fengyuan Li May 2020

Dual Role Of Antimicrobial Peptide Cathelicidin In Alcohol-Associated Liver Disease., Fengyuan Li

Electronic Theses and Dissertations

Patients with alcohol-associated liver disease (ALD) have high morbidity and mortality in its severe forms. One of the major features in different forms of ALD is the altered gut microbiota. Antimicrobial peptides (AMPs) play a crucial role in maintaining gut microbiota homeostasis. LL-37 (known as CRAMP in mouse) is the sole member of the human cathelicidin family and has piqued great research interest for its dual role in modulating microbiota and the immune response in metabolic diseases. Inflammasome activation is an important component of the liver pathophysiology in ALD and requires two signals for its full activation to induce the …
