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 …
Retinoic Acid Regulation Of Thyroid Hormone Action In Bone Cells, Anjali Babbar
Retinoic Acid Regulation Of Thyroid Hormone Action In Bone Cells, Anjali Babbar
Loma Linda University Electronic Theses, Dissertations & Projects
Retinoic acid and thyroid hormone are known to play key roles in the regulation of endochondral ossification. However, the issue of whether these two hormones interact with each other to regulate bone functions remains to be established. We investigated how thyroid hormone and retinoic acid interact to regulate cells involved in endochondral bone formation. We demonstrate that thyroid hormone treatment stimulates differentiation of ATDC5 chondrocytes and promotes formation of mineralized nodules while retinoic acid treatment at high dose inhibits chondrocyte differentiation and formation of mineralized nodules. Furthermore, thyroid hormone induced mineralized nodule formation is inhibited by co-treatment with retinoic acid …
