Abstract: | Immune suppression remains a consistent obstacle to successful anti-tumor immune responses. As tumors develop, they create
a microenvironment that not only supports tumor growth and metastasis but also reduces potential adaptive immunity to tumor
antigens. Among the many components of this tumor microenvironment is a population of dendritic cells which exert profound
immune suppressive effects on T cells. In this review, we discuss our recent findings related to these tumor-associated dendritic
cells and how targeting them may serve to generate more durable anti-tumor immune responses. |
