Microbiota modulation of myeloid cells in cancer therapy

摘要

Myeloid cells represent a major component of the tumor microenvironment where they play divergent dual roles: they can induce antitumor immune responses but mostly they promote immune evasion, tumor progression and metastases formation. Thus, strategies aiming at reprogramming the tumor microenvironment represent a promising immunotherapy approach. Myeloid cells respond to environmental factors including signals derived from commensal microbes. In this Cancer Immunology at the Crossroads overview we discuss recent advances on the effects of the commensal microbiota on myeloid-cell function and how that impacts the response to cancer therapy.
