Correlation analysis of the study population: age vs the analyzed parameters

	Compared parameter
	Stimulation type	SOD2	SIRT1	HSP70^intr	HSP70^surf	TNF	IFN-γ	Carbonyl groups	8-isoprostanes
Age	none	−0.225	0.301	0.300	ns	0.44	ns	−0.423	−0.584
	IL-2	ns	ns	ns	ns	0.478	0.242	−0.385	−0.685
	LPS	ns	0.417	0.409	ns	0.53	ns	−0.491	ns
	PMA/ion	ns	0.273	0.219	0.409	0.379	ns	−0.44	−0.555

All values are presented as statistically significant (p < 0.05) Spearman’s correlation coefficients (R). ‘ns’ denotes statistically not significant. ‘HSP70^intr’ - intracellular HSP70; ‘HSP70^surf’ - surface HSP70; ‘PMA/ion’ – PMA + ionomycin
