Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4+ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing Complex …

The epithelial lining of the small intestine mediates its absorptive and secretory function and thus is a critical component of human health. Regeneration and renewal of the epithelium is the result of proliferation of intestinal stem cells (ISCs). Many cell types and molecular factors are known to regulate the ability of ISCs to proliferate, including adjacent neighboring epithelial cells and the underlying, supportive stromal cells. The microbiome resides in the lumen of the small intestine and is in close contact with the epithelium. Due to its proximity to ISCs, it has been hypothesized that species within the microbiome have the …

Respiratory syncytial virus (RSV) remains a leading cause of hospitalizations and death for young children and adults over 65. The worldwide impact of RSV has prioritized the search for an RSV vaccine, with most targeting the critical fusion (F) protein. However, questions remain about the mechanism of RSV entry and RSV F triggering and fusion promotion. This review highlights these questions, specifically those surrounding a cleaved 27 amino acids long peptide within F, p27.

Diversity And Evolution Of Computationally Predicted T Cell Epitopes Against Human Respiratory Syncytial Virus, Jiani Chen, Swan Tan, Vasanthi Avadhanula, Leonard Moise, Pedro A Piedra, Anne S De Groot, Justin Bahl Jan 2023

Diversity And Evolution Of Computationally Predicted T Cell Epitopes Against Human Respiratory Syncytial Virus, Jiani Chen, Swan Tan, Vasanthi Avadhanula, Leonard Moise, Pedro A Piedra, Anne S De Groot, Justin Bahl

Human respiratory syncytial virus (RSV) is a major cause of lower respiratory infection. Despite more than 60 years of research, there is no licensed vaccine. While B cell response is a major focus for vaccine design, the T cell epitope profile of RSV is also important for vaccine development. Here, we computationally predicted putative T cell epitopes in the Fusion protein (F) and Glycoprotein (G) of RSV wild circulating strains by predicting Major Histocompatibility Complex (MHC) class I and class II binding affinity. We limited our inferences to conserved epitopes in both F and G proteins that have been experimentally …

Confocal Analysis Of Sindbis Virus In Aedes Aegypti Unveils Novel Infection Site At Pyloric Armature, Katie Gillian Peters Jan 2023

Confocal Analysis Of Sindbis Virus In Aedes Aegypti Unveils Novel Infection Site At Pyloric Armature, Katie Gillian Peters

UNF Graduate Theses and Dissertations

Arthropod-borne viruses (arboviruses), such as Sindbis virus (SINV), generate foci of infection within the midgut of viremic blood-fed mosquitoes. Arboviruses can disseminate out of the midgut into the surrounding musculature and hemolymph, eventually making it to the salivary glands where virus can be transmitted by saliva during a subsequent blood-feed. In this study, the virus SINV containing the reporter gene GFP, combined with immunohistochemistry, was imaged using confocal microscopy and used to evaluate the infection within the vector mosquito Aedes aegypti. The spatial distribution of SINV infection revealed two common characteristics of foci generated in the midgut. (1) There …
