TY - JOUR AU - Ziegler-Heitbrock, Loems AU - Hofer, Thomas PY - 2013 M3 - Review TI - Toward a Refined Definition of Monocyte Subsets JO - Frontiers in Immunology UR - https://www.frontiersin.org/articles/10.3389/fimmu.2013.00023 VL - 4 SN - 1664-3224 N2 - In a nomenclature proposal published in 2010 monocytes were subdivided into classical and non-classical cells and in addition an intermediate monocyte subset was proposed. Over the last couple of years many studies have analyzed these intermediate cells, their characteristics have been described, and their expansion has been documented in many clinical settings. While these cells appear to be in transition from classical to non-classical monocytes and hence may not form a distinct cell population in a strict sense, their separate analysis and enumeration is warranted in health and disease.
