Investigating T cell-receptor dynamics during initial response to antigens
Friedman images surgically exposed or explanted lymph nodes to examine T cell behavior. The inflammatory response draws nonspecific macrophages and dendritic cells to the lymph node; these emit their own autofluorescent light as bright as the light from the green fluorescent protein (GFP) marker she uses.
Friedman compensates for background using dual labels. She injects a recipient mouse with T cells...
