title: The host-tumor interface in B-cell non-Hodgkin lymphoma: a new world to investigate.
abstract: Research on B-cell non-Hodgkin lymphoma focuses mainly on oncogenic events occurring in lymphoma cells, but recently a new component has appeared that may be crucial in lymphomagenesis: the tumor microenvironment. Indeed, compelling evidence demonstrates the key role played by nonmalignant bystander cells in the establishment and proliferation of the tumor. Among these cells, stromal cells, monocytes/macrophages, and T cells in lymphoid organs have all been described as contributing to tumor progression. Interactions linked to cell-cell intimate contacts-but also mediated through soluble mediators such as cytokines and chemokines-do form a specific network. All these interrelations directed by the tumor create a friendly environment for lymphoma cells that permits them to proliferate. Blocking the cross-talk between the tumor microenvironment and lymphoma cells may thus represent a promising new strategy for treating B-cell malignancies.
