Evaluation Of Tick-Derived Peptides For Transmission-Blocking Vaccine Candidates, Madelyn Futral
Evaluation Of Tick-Derived Peptides For Transmission-Blocking Vaccine Candidates, Madelyn Futral
Honors Theses
The lack of effective preventive measures for tick-borne diseases represents a major public health challenge. Transmission-blocking vaccines targeting tick molecules essential for feeding or reproduction could provide a sustainable and broad-spectrum solution. In this study, we evaluated two tick-derived proteins as potential vaccine antigens, subolesin, a key regulator of blood-feeding and cellular processes, and vitellogenin, a protein involved in egg development. Using bioinformatic tools, we identified immunogenic peptide sequences from each protein and chemically conjugated them to virus-like particles (VLPs) to enhance antigen presentation. C57BL/6 mice were immunized intradermally with VLP-peptide conjugates, followed by a booster dose. Blood and spleen …
The Role Of Oncomodulin In The Central Nervous System Inflammation, Evan Paltjon
The Role Of Oncomodulin In The Central Nervous System Inflammation, Evan Paltjon
Honors Theses
Acoustic overexposure in mice leads to an excess of calcium influx in outer hair cells (OHCs) and causes permanent hearing loss due to death of OHCs. Oncomodulin is a parvalbumin calcium buffering protein located in OHCs of the cochlea. Early pilot studies indicate that genetic deletion of OCM results in immune-related pathology throughout the cochlea. Why and how this occurs is unknown. Studies in wild type (WT) and OCM knockout (KO) mice demonstrate greater numbers of immune cells are associated with noise exposure in an OCM knockout than in WT. Expression of toll-like receptor 4 (TLR4) leads to the recruitment …
The Relationship Between Glucocorticoids And The Humoral Immune Response To Mycoplasma Gallisepticum Challenges In Eastern Bluebirds, Joshua Smith
Honors Theses
Numerous studies have examined relationships between adrenal glucocorticoids and the immune system’s ability to fight disease. The relationship can vary, with glucocorticoids having either stimulatory or inhibitory effects. The pathogenic bacterium Mycoplasma gallisepticum (MG) elicits an adaptive immune response in birds, in which B cells produce MG-specific antibodies to fight the infection and prevent reoccurrence. Previous research found that Eastern Bluebirds that produce the most antibodies in response to MG infection also have the highest glucocorticoid levels. This finding led to the current study investigating whether corticosterone, the primary glucocorticoid in birds, stimulates production of antibodies in response to immune …
The Impact Of Tricaine Methanesulfonate, 2-Phenoxyethanol, And Carvone-Methyl Salicylate On The Innate Immune Response Of Zebrafish (Danio Rerio), Charles R. Wulff
The Impact Of Tricaine Methanesulfonate, 2-Phenoxyethanol, And Carvone-Methyl Salicylate On The Innate Immune Response Of Zebrafish (Danio Rerio), Charles R. Wulff
Honors Theses
Anesthesia plays a vital role in the maintenance of aquaculture species, where it is used to minimize stress during complex handling tasks such as transport, assessment, and harvesting. However, anesthetics have been shown to suppress the innate immune response, which could impact immunity and increase risk of infection. Tricaine methanesulfonate (MS-222) and 2-Phenoxyethanol (2-PE) represent two of the most commonly used anesthetics in aquaculture, with R-(+)-carvone, in the form of carvone-methyl salicylate (CMS) has recently been proposed as an alternative anesthetic for food fish. These three anesthetics were used to assess the influence of anesthetics on the immune system of …
