Let-7 Mirnas Program The Fate Of Cd8 T Cells, Alexandria Wells
Doctoral Dissertations
CD8 T cells are the cytotoxic effectors of the adaptive immune response, clearing virally infected and cancerous cells within the host. CD8 T cells acquire their cytotoxic function by differentiating into cytotoxic T lymphocytes (CTLs). Once the CTLs have cleared the antigen, the majority of responding cells will die during contraction; however, a small population of the antigen-specific responders will remain, differentiating into long-lived memory cells that provide potent protection to the host upon re-encounter with the antigen. These differentiation programs often become disturbed in cases of chronic infection and cancer. Instead, CD8 T cells are subverted into the so-called …

Hybridized Polymeric Nano-Assemblies: Key Insights Into Addressing Mdr Infections, Ryan Landis
Doctoral Dissertations
Multidrug-resistant (MDR) bacteria contribute to more than 700,000 annual deaths world-wide. Millions more suffer from limb amputations or face high healthcare treatment costs where prolonged and costly therapeutic regimens are used to counter MDR infections. While there is an international push to develop novel and more powerful antimicrobials to address the impending threat, one particularly interesting approach that has re-emerged are essential oils, phytochemical extracts derived from plant sources. While their antimicrobial activity demonstrates a promising avenue, their stability in aqueous media, limits their practical use in or on mammals. Inspired by the versatility of polymer nanotechnology and the sustainability …
Nascent Dna Proteomics Analysis Uncovers Dna Replication Dynamics In The Human Pathogen Trypanosoma Brucei, Maria Rocha Granados
Nascent Dna Proteomics Analysis Uncovers Dna Replication Dynamics In The Human Pathogen Trypanosoma Brucei, Maria Rocha Granados
Doctoral Dissertations
DNA is the substrate of many cellular processes including DNA replication, transcription and chromatin remodeling. These processes are coordinated to maintain genome integrity and ensure accurate duplication of genetic and epigenetic information. Genome-wide studies have provided evidence of the relationship between transcription and DNA replication timing. A global analysis of DNA replication initiation in T. brucei showed that TbORC1 (subunit of the origin recognition complex, ORC) binding sites are located at the boundaries of transcription units. Although recent studies in T. brucei indicate functional links among DNA replication and transcription, the underlying mechanisms remain unknown. In this study, we adapted …
