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 …

Sars-Cov-2: Tale Of A Microscopic Murderer, Josiah P. Garner

Quest

Independent Study

Research in progress for BIOL1406: Biology for Science Majors I

Faculty Mentor: Amina Tassa, Ph.D.

I am delighted to introduce Josiah Garner’s “SARS-CoV-2: Tale of a Microscopic Murderer.” This independent study assignment explores the impact of a novel, deadly, and worldwide virus. The assignment also examines the fast development of vaccines to control the spread and reduce the symptoms of the virus.

Josiah’s paper focuses on the early history of the emergence of COVID-19, the world response, and vaccine development. He demonstrates critical thinking skills and effectively utilizes various research methods to obtain and communicate his information. Josiah …

Generation Of Chimeric Rhinoviruses Presenting Sars-Cov-2 Broadly Neutralizing Epitopes And Their Antigenicity Characterization, Danish Ansari

Biotechnology Theses

The global COVID pandemic is not yet fully under control as there were over 21 million new cases of SARS-CoV-2 infections and over 50,000 deaths globally as of January of 2022. A heavily mutated variant of concern, Omicron is responsible for most of these cases which demands an urgency for a new vaccine. NIH reports over 180 vaccine candidates that use various strategies currently in development. However, a recurring concern with these vaccines is that the continuous viral mutations decrease the efficacy of vaccines. Therefore, we proposed to construct a human rhinovirus (HRV) based chimeric virus containing highly conserved, broadly …

The Psychology Of Science Denialism And Lessons For Public Health Authorities, Brenna Moreno, Molly J. Walker Wilson

All Faculty Scholarship

As it wreaked tragedy on the world, the outbreak of COVID-19 helped expose a pandemic of a different kind, one steeped in distrust and contrarianism. This movement, termed science denialism, has been lurking and undermining public health efforts for decades. Specifically, it is “the employment of rhetorical arguments to give the appearance of legitimate debate where there is none, an approach that has the ultimate goal of rejecting a proposition on which a scientific consensus exists.” Unlike skepticism, which is “doubt as to the truth of something” and works to progress both science and society, denialism is characterized by individuals’ …

Development Of An Attenuated Zika Virus By Editing The 5’ Untranslated Region, E. Ashley Thompson

Master's Theses

Zika Virus (ZIKV) is a mosquito-transmitted flavivirus that usually causes no symptoms to mild febrile in humans, and it has been regarded as an insignificant pathogen to public health. However, recent outbreaks of ZIKV infection have revealed that ZIKV can cause severe neurological effects in adults, such as Guillain-Barre Syndrome (GBS), and in infants whose mothers acquired the virus during pregnancy, causing Congenital Zika Syndrome (CZS). Currently, no approved vaccine is available and there is a critical need to develop an effective and safe vaccine. While most vaccine developmental strategies target the viral prM-E protein of ZIKV, we aimed to …

Haemonchus Contortus Antigen Identification And Use Of Tropomyosin In Ovine Vaccine Development, Brynnan P. Russ

Graduate Theses, Dissertations, and Problem Reports (ETD)

Globally, the small ruminant industry loses hundreds of millions of dollars due to parasitism by the gastrointestinal nematode Haemonchus contortus. This parasite feeds on blood in the host’s abomasum leading to disease including anemia, hypoproteinemia, lethargy, and death. There have been exhaustive efforts to manage this parasite including different management applications, anthelmintic treatment, and now integration of resistance genetics into a flock. Like antibiotics, overuse of anthelmintics has led to resistance of H. contortus to these drugs. Therefore, other methods of control are the main focuses of many research initiatives. St. Croix are a resistant breed of sheep that mount …

Utilization Of Cholera Toxin B As An Adjuvant For The Subunit Pspa Vaccine, Provides Effective Protection Against Streptococcus Pneumoniae Challenge, Daniel R. Pinho

Seton Hall University Dissertations and Theses (ETDs)

Streptococcus pneumoniae is a prevalent human pathogen associated with pneumonia. It is estimated that approximately 1 million people around the world die each year, specifically with young children and the elderly comprising a significant portion. Currently, antibiotics can treat the infection but individuals such as the young or elderly are more susceptible to bodily damage from symptoms, such as pneumonia, meningitis, and sepsis, thus require more preventive measures. As a result, vaccinations are a key solution to providing effective protection against infectious pathogens. Presently, two vaccinations exist in the market: PPSV₂₃ and PCV₁₃, which only protect against …

Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez

Biology: Student Scholarship & Creative Works

ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 system, have …
