Immunomodulation Of Myeloid-Derived Suppressor Cells By Particulate B-Glucan In Cancer., Sabrin Husein Albeituni
Electronic Theses and Dissertations
Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of immature myeloid cells that promote tumor progression. In this study, we investigated the effect of dectin-1 stimulation by yeast-derived particulate β-glucan in MDSC function and differentiation in cancer. In vivo treatment of mice bearing lewis lung carcinoma and mammary cell carcinoma with particulate β-glucan decreased tumor weight and splenomegaly, and reduced the accumulation of polymorphonuclear-MDSC (PMN-MDSC) but not monocytic-MDSC (M-MDSC) in the spleen and tumor. In addition, particulate β-glucan differentially modulated the function of different MDSC subsets; it enhanced PMN-MDSC respiratory burst and apoptosis, and induced the differentiation of M-MDSC into …
Cardiovascular Regulation And Effects Of Respiratory Motor Training In Patients With Chronic Spinal Cord Injury., Bonnie Legg Ditterline
Cardiovascular Regulation And Effects Of Respiratory Motor Training In Patients With Chronic Spinal Cord Injury., Bonnie Legg Ditterline
Electronic Theses and Dissertations
This dissertation attempts to discover the mechanisms between cardiovascular and respiratory motor control post spinal cord injury (SCI): in normal, non-injured (NI) persons, cardiovascular regulation is dependent upon respiration, but there is nothing that suggests the mechanism for this relationship post-SCI. Thus we hoped to evaluate various aspects of cardiovascular regulation to further illustrate how this relationship is changed or unchanged by SCI. Chapter I describes the anatomy and physiology of the spine, respiratory system, and cardiovascular system in a NI person, and then describes how the function of these systems is changed by SCI. In addition, we describe therapies …
Development Of A Vascularized, Induced Pluripotent Stem Cell-Derived Liver-Tissue Mimic For Therapeutic Applications., Venkat Madhav Ramakrishnan
Development Of A Vascularized, Induced Pluripotent Stem Cell-Derived Liver-Tissue Mimic For Therapeutic Applications., Venkat Madhav Ramakrishnan
Electronic Theses and Dissertations
This dissertation describes the incorporation of several technologies (stem cells, gene therapy, tissue engineering and regenerative medicine) into a single project that aims to produce a liver-tissue mimic for therapeutic applications. The liver is arguably one of the most complex organs in the body. In addition to its remarkable capacity to regenerate, it performs a host of vital functions. As a result, its impairment has widespread systemic consequences. The work described herein focused on the liver in the context of cardiovascular disease and used the heritable disorder Familial Hypercholesterolemia (FH) as a clinical disease model. As (a) the only definitive …
