Oncolytic Virus Immunotherapy: Development And Potential For Cancer Treatment, Olivia Guinness
Oncolytic Virus Immunotherapy: Development And Potential For Cancer Treatment, Olivia Guinness
Honors Scholar Theses
The American Cancer Society estimates that in 2023, 1,958,310 new cancer cases and 609,820 cancer deaths will occur in the United States [16]. A promising therapeutic option that has been supported by recent clinical trials is the use of oncolytic viruses to treat malignant tumors. The mechanism of action of existing treatments, such as chemotherapy, radiotherapy, and surgery, differs from that of oncolytic virus therapy because oncolytic viruses are able to affect cancer cells with specificity, minimizing side effects. When infecting a normal, non-cancerous cell, oncolytic viruses do not replicate, leaving healthy cells unaffected. In tumor cells, oncolytic viruses will …

Characterization Of A Mycoplasma Pneumoniae Cards Toxin Mutant, Nikaash Pasnoori
Honors Scholar Theses
Mycoplasma pneumoniae is a high-burden pathogen which causes mild to significant infections of the respiratory system. According to the CDC, an estimated two million cases occur yearly in the United States alone, demonstrating the widespread effect of the pathogen. In addition to being the cause of respiratory infections, M. pneumoniae has also been implicated in exacerbating pre-existing asthma conditions. These morbidities make finding a vaccine candidate a vital part of easing the healthcare burden caused by the pathogen. The current mechanism of infection is unknown, but recent evidence points to the Community Acquired Respiratory Distress Syndrome (CARDS) toxin as being …
The Signaling Pathways Of Metallothionein-Mediated Chemotaxis In Breast Cancer, Jennifer Messina
The Signaling Pathways Of Metallothionein-Mediated Chemotaxis In Breast Cancer, Jennifer Messina
Honors Scholar Theses
Metallothionein (MT) is a small, thiol rich protein released into the extracellular environment in response to stress. Elevated expression of MT has been linked to many inflammatory diseases including inflammatory bowel diseases, diabetes, and cancer. In breast cancer, high expression of MT has been associated with poor patient prognosis. Previous studies have shown that MT acts as a chemoattractant in lymphocytes, and that UC1MT, a monoclonal anti-MT antibody, can block this chemotactic response. In addition, it has been shown that both Cholera toxin and Pertussis toxin, which are known antagonists of G-protein coupled receptors, can inhibit MT-mediated chemotaxis. Here, I …
Manipulation Of The Microbiome And Its Impact On Functional Recovery Following Ischemic Stroke, Michal Jandzinski
Manipulation Of The Microbiome And Its Impact On Functional Recovery Following Ischemic Stroke, Michal Jandzinski
Honors Scholar Theses
Each year, nearly 800,000 individuals residing in the United States will have a stroke. Of these, about 130,000 cases will prove fatal while many of the survivors will be forced to live with disability for the remainder of their lives. Out of all strokes over 87% are ischemic strokes. The widespread incidence of this debilitating condition costs the United States an estimated $36.5 billion dollars every single year. Despite this, clinicians are armed with very little to combat the disease. Recent research developments have brought about the rise in awareness about the importance of the microbiome, the various gut flora …
Modeling The Adaptive Immune Response To Mutation-Generated Antigens, Rory J. Geyer
Modeling The Adaptive Immune Response To Mutation-Generated Antigens, Rory J. Geyer
Honors Scholar Theses
Somatic mutations may drive tumorigenesis or lead to new, immunogenic epitopes (neoantigens). The immune system is thought to represses neoplastic growths through the recognition of neoantigens presented only by tumor cells. To study mutations as well as the immune response to mutation-generated antigens, we have created a conditional knockin mouse line with a gene encoding, 5’ to 3’, yellow fluorescent protein (YFP), ovalbumin (which is processed to the immunologically recognizable peptide, SIINFEKL), and cyan fluorescent protein (CFP), or, YFP-ovalbumin-CFP. A frame shift mutation has been created at the 5’ end of the ovalbumin gene, hence YFP should always be expressed, …
In Vitro Expression And Purification Of Class I Mhc Molecules, Loi Cheng
In Vitro Expression And Purification Of Class I Mhc Molecules, Loi Cheng
Honors Scholar Theses
The major histocompatibility complex (MHC) is a gene family responsible for many critical functions of the immune system in most vertebrates. The MHC consists of three classes differentiated by their structure and function, and MHC class I encodes antigen binding proteins as well as chaperone and accessory proteins such as tapasin. The purpose of this project is to reconstitute several human MHC class I molecules in their peptide-filled and peptide-deficient forms, and to purify these proteins for biochemical study. The expressed proteins include wild type and mutant variants of the fusion protein human leukocyte antigen HLA-B*0801-fos, and human beta-2-microglobulin (β2m). …
