Trophoblast differentiation and invasion is essential for normal implantation and establishment of the maternal-fetal interface, which allows for proper nutrient exchange and support of the fetus. For this to occur, cytotrophoblasts must undergo an epithelial to mesenchymal transition and differentiate into migratory and invasive extravillous trophoblasts (EVTs) that invade the maternal decidua and myometrium. Trophoblast differentiation, migration and invasion is highly regulated by a complex network of signaling pathways, adhesion molecules and transcription factors and is important for the remodeling of maternal spiral arteries from low flow, high resistance to high flow, low resistance vessels to allow optimal perfusion of …

USF Tampa Graduate Theses and Dissertations
Regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSC) have been extensively studied in the past 30-40 years. Their potent suppressive capacity shown in several pathological and clinical settings, such as cancer and transplantation, has made it evident that better understanding their development and function is critical.
Specifically, Tregs play a pivotal role in preventing autoimmunity, graft-versus-host disease (GvHD), and organ graft rejection. We previously demonstrated that germline or induced SH2 domain-containing inositol 5-phosphatase (SHIP) deficiency in the host abrogates GvHD. Here we show that SHIP-deficiency promotes an increase of FoxP3+ cells in both the CD4+CD25+ and the CD4+CD25- T …
