Electronic Theses and Dissertations
Glioblastoma is the most commonly diagnosed central nervous system primary malignancy and it is considered a terminal diagnosis with few treatment options available. Glioblastoma tumors frequently develop treatment resistance due in part to their highly heterogenic nature. The heterogeneity of glioblastoma is partially attributed to the presence of glioma stem-like cells (GSC), which are highly invasive and resistant to chemotherapy and irradiation treatments. Signaling of the receptor tyrosine kinase MET is a known regulator of GSC. Glioblastoma patients have an increasingly poor prognosis that corresponds with increasing MET expression. Both GSC and MET are known to contribute to treatment resistance …
Immune Activation Induces Telomeric Dna Damage, Reduces Memory Precursors, And Promotes Short-Lived Effector T Cell Differentiation In Chronic Hcv Infection, Lam Nguyen
Electronic Theses and Dissertations
Chronic hepatitis C virus (HCV) infection exhibits persistent high viral load, inducing T cells differentiation and dysfunction in chronically infected individuals. Recent longitude studies in both HCV specific- and bulk T cells reveal that chronic immune stimulation is the driving force for the impaired T cell functions, however, the underlying mechanisms remain elusive. Here, we show that peripheral CD4+ T cells from chronically HCV-infected patients exhibit lymphopenia with the reduction of naïve population and expansion of effector memory T cells. CD4+ T cells from HCV patient also display elevated activation markers. including HLA-DR, GLUT1, Granzyme B, and short-lived …
