Action of GDF-15 (IMAGE) Trophic Communications Caption This foundational research describes a mechanistic link between tumor-produced Growth Differentiation Factor-15 (GDF-15) and the LFA-1/ICAM-1 cell adhesion axis. The interaction between LFA-1/ICAM-1 is a critical step in the infiltration of T cells into the tumor microenvironment.
