Suppression Of Anti-Tumor Immunity In Chronic Lymphocytic Leukemia Via Interleukin-10 Production, Sara Alhakeem
Suppression Of Anti-Tumor Immunity In Chronic Lymphocytic Leukemia Via Interleukin-10 Production, Sara Alhakeem
Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics
The most common human leukemia is B-cell chronic lymphocytic leukemia (B-CLL), which is characterized by a progressive accumulation of abnormal B-lymphocytes in blood, bone marrow and secondary lymphoid organs. Typically disease progression is slow, but as the number of leukemic cells increases, they interfere with the production of other important blood cells, causing the patients to be in an immunosuppressive state. To study the basis of this immunoregulation, we used cells from the transgenic Eμ-TCL1 mouse, which spontaneously develop B-CLL due to a B-cell specific expression of the oncogene, TCL1. Previously we showed that Eμ-TCL1 CLL cells constitutively …
Role Of Intracellular Growth During The Gastrointestinal Stage Of Listeria Monocytogenes Infection, Grant Steven Jones
Role Of Intracellular Growth During The Gastrointestinal Stage Of Listeria Monocytogenes Infection, Grant Steven Jones
Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics
Listeria monocytogenes is a facultative intracellular bacterium that causes foodborne disease in humans. L. monocytogenes invade the gut mucosa and then disseminate, causing systemic infections associated with high mortality rates in immunocompromised individuals. It is unknown how L. monocytogenes traffic to the mesenteric lymph nodes, which represent an important bottleneck for systemic spread. In addition, little is known about the gastrointestinal stage of infection due to the general resistance of mice to oral infection with L. monocytogenes. Our laboratory developed a novel foodborne mouse model of listeriosis utilizing a murinized strain of L. monocytogenes to investigate the gastrointestinal stage …
