Monocytes and Macrophages: A Fresh Look at Functional and Phenotypic Diversity.

This Forum addresses the functional and phenotypical diversity of monocytes and macrophages and explores new mechanisms that contribute to the plasticity of these cells. The contributors provide in-depth and comprehensive overviews on selected key mechanisms underlying macrophage plasticity and diversity and how they related to human disease and aging. What emerges from these contributions is the importance of the interactions of macrophages with their dynamic microenvironment and the need for a better mechanistic understanding of how these cells sense environmental cues, integrate and respond to these signals, and thereby themselves help shape their microenvironment.
