Figure 8: The elderly has higher non-classical monocyte count and plasma level of SASP cytokines.

a Number of monocytes from each subset expressed as a percentage of the total number of monocytes. b Absolute number of monocytes from each subset present in a µL of whole blood. c TNF-α and IL-8 levels in the plasma, analyzed by Luminex assay. Each dot represents one donor; line represents median; (a–b) n = 30 each for both young and elderly individuals; (c) n = 20 for young, n = 30 for elderly; ***p < 0.001. CL: classical, ITM: intermediate, NC: non-classical
