Safety Evaluation Of Epicertin, An Oral Biotherapeutic Candidate For Treating Ulcerative Colitis: A 28-Day Repeated Dose Toxicity Study., Jimmy Fernando Cifuentes Jimenez Dec 2025

Safety Evaluation Of Epicertin, An Oral Biotherapeutic Candidate For Treating Ulcerative Colitis: A 28-Day Repeated Dose Toxicity Study., Jimmy Fernando Cifuentes Jimenez

Electronic Theses and Dissertations

Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic, relapsing inflammation of the colon and rectum with limited treatment options. Among them, immunosuppressive agents have a high rate of adverse side effects and do not cure the disease. EPICERTIN (EPT), a recombinant variant of the cholera toxin B subunit (CTB) with a C-terminal hexapeptide extension consisting of a KDEL endoplasmic reticulum (ER) retention motif, is a promising oral biotherapeutic candidate for the treatment of UC. EPT has demonstrated mucosal healing activity in mouse models of colitis and human colonic explants. EPT's mechanism of action involves binding to GM1 …


Effect Of Histidine Tag On The Enzymatic Activity Of Pseudolysin And Its Interaction With The Streptomyces Metalloprotease Inhibitor (Smpi) Protein, Adewale Adeboye Adewole Aug 2025

Effect Of Histidine Tag On The Enzymatic Activity Of Pseudolysin And Its Interaction With The Streptomyces Metalloprotease Inhibitor (Smpi) Protein, Adewale Adeboye Adewole

Electronic Theses and Dissertations

Pseudolysin (PLN) protein is a major virulent factor in Pseudomonas aeruginosa infection. PLN belongs to the family of zinc-dependent metalloproteases. It is naturally inhibited by a smaller protein called streptomyces metalloprotease inhibitor (SMPI), secreted by Streptomyces nigrescens. Previous and current studies demonstrate that the interaction between PLN and SMPI offers unique mechanistic insights for drug development against infections caused by P. aeruginosa. This study investigated the effect of N-terminal Histidine (His) tag on the enzymatic activity of PLN and its interaction with SMPI. His-tagged PLN and SMPI proteins were expressed in bacteria and purified by affinity chromatography …


Cbl Regulation Of C-Met Signaling In Corneal Epithelial Cells., Kate Elise Tarvestad Laise Aug 2025

Cbl Regulation Of C-Met Signaling In Corneal Epithelial Cells., Kate Elise Tarvestad Laise

Electronic Theses and Dissertations

The cornea is the most anterior portion of the eye and permits light passage through to retina, allowing formation of a clear image as long as it remains healthy. If the cornea sustains damage, it creates and entrance for foreign body invasion, infection, and ultimately blindness in the immunocompromised eye. Healing the corneal tissue is critical for vision restoration and pain alleviation, as it is the most densely innervated tissue in the body. Growth factors and their cognate receptors are currently under investigation as tools to restore proper corneal physiology. We hypothesize that manipulating the hepatocyte growth factor (HGF) /c-Met …


Decreasing Unintentional Pregnancies For Tennesseans, Paula M. Todd Oct 2021

Decreasing Unintentional Pregnancies For Tennesseans, Paula M. Todd

Electronic Theses and Dissertations

In 2018, 49% of all pregnancies in the United States were unintended, with women with a lower- income status being five times more likely to experience an unplanned pregnancy. Tennessee has a high rate of unintended pregnancies, particularly among the uninsured, low-income, and rural teen populations; some 22% of these unintended pregnancies end in abortion. Oral or transdermal contraceptives that are affordable and accessible for women of childbearing age can reduce unintentional pregnancies. The addressed gap in clinical practice was that contraceptives are not currently available over the counter in Tennessee pharmacies without a prescription, which necessitates a costly medical …


Machine Learning Applied To Colloidal Properties Of Perfluorocarbon Nanoemulsions For Imaging In Ards/Ali, Marco Hosfeld May 2021

Machine Learning Applied To Colloidal Properties Of Perfluorocarbon Nanoemulsions For Imaging In Ards/Ali, Marco Hosfeld

Electronic Theses and Dissertations

Acute Respiratory distress Syndrome (ARDS) and Acute Lung Injury (ALI) are inflammatory lung pathologies consisting of non-hydrostatic pulmonary edema leading to hypoxia and impaired gas exchange in the lungs. ARDS/ALI is both difficult to study and treat as it is not in itself a specific pathology but rather a syndrome consisting of many pathologies that vary case by case. It is, however, consistently characterized by an explosive acute inflammatory response in the lung parenchyma leading to hypoxia. Although time has seen to an increase in the understanding of ARDS/ALI, the mortality rate remains in the range of 30-50%. For these …


Macromolecule Loading On Plga Particles Through Surface Adsorption, Yiwei Wang Aug 2018

Macromolecule Loading On Plga Particles Through Surface Adsorption, Yiwei Wang

Electronic Theses and Dissertations

The advent of biotherapeutics have impacted the ways in which diseases are treated. In many instances development of recombinant proteins and oligonucleotides into therapeutics are slowed by poor stability of the candidate drugs. Progress has been made in using polymeric particles as carriers of macromolecule drugs. Historically the method is to encapsulate biological drugs into spherical polymeric matrices. Owing to its biocompatible and biodegradable nature, poly (d,l-lactic-co-glycolic acid) (PLGA) has been used extensively in formulating biological drugs into nano- and micro-sized particles. The development of PLGA biologic formulations, however, has been hampered by matrix acidification; the hydrolysis of the polymer …
