Lymphocyte migration is critical for recognizing pathogenic challenges in a timely manner and generating effective, rapid immune responses. Lymphocyte numbers in secondary lymphoid tissues such as lymph nodes are rapidly and dramatically increased during an immune response. Lymphocytes use specific adhesion molecules and intracellular signaling cascades to migrate and enter secondary lymphoid tissues under resting conditions. It is not clear if the same migration and/or entry pathways are utilized when secondary lymphoid …

Evaluation And Adaptation Of Live-Cell Interferometry For Applications In Basic, Translational, And Clinical Research, Kevin A. Leslie

Theses and Dissertations

Cell mass is an important indicator of cell health and status. A diverse set of techniques have been developed to precisely measure the masses of single cells, with varying degrees of technical complexity and throughput. Here, the development of a non-invasive, label-free optical technique, termed Live-Cell Interferometry (LCI), is described. Several applications are presented, including an evaluation of LCI’s utility for assessing drug response heterogeneity in patient-derived melanoma lines and the measurement of CD3+ T cell kinetics during hematopoietic stem cell transplantation. The characterization of mast cells during degranulation, the measurement of viral reactivation kinetics in Kaposi’s Sarcoma, and drug …
