Comparison of the immunosenescence markers between healthy controls and systemic lupus erythematosus patients

Variable	Healthy controls (n = 53)	SLE patients (n = 53)	p-value
CD4+CD57+ [%]	1.0 (0.4–1.4)	1.2 (0.6–2.8)	0.108
CD4+KLRG1+ [%]	0.3 (0.1–0.5)	3.1 (1.3–5.5)	0.000*
CD8+CD57+ [%]	2.4 ±2.0	11.6 ±7.1	0.000*
CD8+KLRG1+ [%]	0.3 ±0.1	13.7 ±7.5	0.000*
IFN-γ levels [pg/ml]	6.2 (5.3–8.9)	193.1 (139.1–225.1)	0.000*

IFN-γ – interferon γ, KLRG1 – killer cell lectin like receptor G1
