Howie Seay, BS, LATg: Senior Biological Scientist, Laboratory Manager
Howie, Danielle, and Crasher
Howie joined the UFHealth Diabetes Institute as part of the Brusko Lab in 2011 after giving back to society as a high school science teacher. His tasks in the lab include processing peripheral and cord blood samples, flow cytometric analysis of human immune cells and fluorescence-activated cell sorting, lab website and database maintenance, and the other various support duties of a research lab manager.
Howie’s current project involves isolating naïve regulatory T cells from cryogenically preserved umbilical cord blood units for expansion and potential re-infusion of autologous immune cells into children with type 1 diabetes. We hope that this therapy can be used to repopulate the immune system with T-cells that suppress autoimmunity and reverse the loss of insulin-producing ß-cells of the pancreas.
Howie is also working on DNA methylation signatures in Pancreatic-draining lymph nodes in nPOD donors. These patterns can signify whether genes are turned on or off in a cell, and early evidence shows that cytotoxic T-lymphocytes in T1D patients are different at the epigenetic level when compared to healthy donor samples. The next step is determining why those differences happen and how those differences make the cells function in a unique way to aid in diabetes pathogenesis.
