Conventionally, human monocyte sub-populations are classified according to surface marker expression into classical (CD14++CD16− ), intermediate (CD14++CD16+ ) and non-classical (CD14+ CD16++) lineages. The involvement of non-classical monocytes, also referred to as proinflammatory monocytes, in the pathophysiology of diseases including diabetes mellitus, atherosclerosis or Alzheimer’s disease is well recognized. | Quantitative whole-cell MALDI-TOF MS fingerprints distinguishes human monocyte sub-populations activated by distinct microbial ligands
