Fig. 3From: Immune cell extracellular vesicles and their mitochondrial content decline with ageingMultiple plasma EVs of immune cells dramatically declined with age. Univariable regression analysis was used to assess associations between age and the percentage of each plasma EV subset expressing the particular surface marker in HCs (n = 28). The graphs represent results with p < 0.05, while full report of all the tested markers is presented in Additional file 6: Fig. S5Back to article page
