Understanding Immunometabolic And Suppressive Factors That Impact Cancer Development, Rebecca Swearingen Hesterberg

USF Tampa Graduate Theses and Dissertations

The immune system is responsible for surveillance against pathogens and malignancies and adoptive transfer of antigen-specific T is a powerful new cancer treatment option. There is a clinical need to understand more about the normal regulatory processes that prevent immunosurveillance and how to manipulate this for clinical benefit. This project aims to understand T cells from three different angles. First, the biological role of the negative regulator cereblon (CRBN) was investigated in CD8+ T cells and my studies showed that higher levels of specific derivatives downstream of the amino acid glutamine may be beneficial to T cells in the immune …

Lenalidomide Targets The T-Cell Co-Stimulatory Pathway To Mediate Immune Modulation, Jessica Marie Mcdaniel

USF Tampa Graduate Theses and Dissertations

T-cells are lymphocytes that make up part of the adaptive arm of the immune system, and are essential for efficient protection from and eradication of viruses and pathogens. T-cells not only play an important role in protection from external agents, but also regulate and prevent activation towards self-peptides and detect and remove erratically growing cells. Alterations in T-cell activation and suppression contribute to auto-immunity, immunocompromised disorders, and cancer progression.

The immune system, and T-cells in particular, provides daily surveillance, recognition and destruction of aberrant cells. Although the immune system is proficient at suppressing malignant progression, tumor cells acquire various methods …
