Interleukin-12 Cyclophosphamide Colorectal cancer Inflammatory myeloid cells
Medina-Echeverz J, Berraondo P. Colon cancer eradication after chemoimmunotherapy is associated with intratumoral emergence of proinflammatory myeloid cells. Oncoimmunology 2012 Jan 1;1(1):118-120.
Interleukin-12 immune stimulation lacks efficacy in established solid tumor models. Disruption of tumor microenvironment homeostasis by low-dose cyclophosphamide prior to interleukin-12 gene therapy led to CD8+ T cell-driven established tumor rejection. This only takes place when inflammatory myeloid cells infiltrate the tumor bed, and is crucial for the latter antitumor response.
