The Use Of Surface Cytokines As Biomarkers In B Cell Mediated Autoimmune Diseases, Abby Jones Weldon Dec 2014

The Use Of Surface Cytokines As Biomarkers In B Cell Mediated Autoimmune Diseases, Abby Jones Weldon

Loma Linda University Electronic Theses, Dissertations & Projects

RA and SLE are B cell-mediated autoimmune diseases dominated by autoantibodies that affect over 1.5 million Americans. Together RA and SLE contribute to over 29 billion in healthcare costs, therefore due to the high financial burden and physical toll of these diseases on the population, there is a critical need to effectively and efficiently diagnose and treat RA and SLE patients. The aim of our studies was to identify biomarkers and drug targets to improve the identification and treatment of RA and SLE patients. As discussed above, APRIL, BAFF and TSLP have been implicated in the pathogenesis of RA and …


Cd21 And Cd24 Co-Expression: A Translational Model Between Mouse And Human, Abigail Benitez Jun 2014

Cd21 And Cd24 Co-Expression: A Translational Model Between Mouse And Human, Abigail Benitez

Loma Linda University Electronic Theses, Dissertations & Projects

Systemic Lupus Erythematosus and Rheumatoid Arthritis are B cell-mediated autoimmune diseases that afflict millions of people worldwide. B cell-targeted therapies for these diseases result in variable clinical outcomes. Thus, a need exists to better understand the dynamics of human B cell production and function. The mouse model has provided a foundation for understanding the mechanisms involved in human B cell development and autoimmune disease. However, differences in mouse and human B cells are not fully understood. Our work shows that the co-expression of CD21 and CD24, determined by 7-color flow cytometry, can be used to demarcate developmental subsets of B …
