Interferon-γ–Dependent Infiltration of Human T Cells into Neuroblastoma Tumors<i>In vivo</i>

Abstract

Interferon-gamma overcomes critical obstacles to the killing of human neuroblastoma cells by specific T cells. Together, these findings provide a rationale for the further testing of interferon-gamma as an approach for improving the efficacy of T cell-based therapies for neuroblastoma and other major histocompatibility complex class I-deficient malignancies. In addition, we describe a model that may expedite the preclinical screening of approaches aimed at augmenting T-cell trafficking into human tumors.
