Cell surface density and fold increase in cell surface markers on CD56⁺ NK cells stimulated either with Hsp70 peptide TKD (2 μg/mL), CX−/CX+ exosomes (10 μg/mL), and lysates (10 μg/mL) derived thereof as compared to unstimulated NK cells

NK cell marker	Mean fluorescence intensity (fold increase)
	TKD	CX− exos	CX+ exos	CX− lys	CX+ lys
CD94	336 (2.0)^*	227 (1.3)	315 (1.9)^*	241 (1.4)	241 (1.4)
NKp30	108 (2.6)^*	104 (2.4)^*	117 (2.7)^*	101 (2.4)^*	103 (2.4)^*
NKp44	266 (2.2)^*	293 (2.4)^*	313 (2.6)^*	256 (2.1)	293 (2.4)^*
NKp46	342 (1.3)	320 (1.2)	354 (1.4)	347 (1.3)	333 (1.3)
NKG2D	213 (1.1)	276 (1.4)	283 (1.4)	273 (1.4)	259 (1.3)
CD69	185 (3.1)^*	139 (1.8)	113 (2.4)^*	119 (1.8)	118 (1.8)
CD158a	524 (1.2)	560 (1.2)	505 (1.1)	433 (1.0)	442 (1.0)

NOTE: Data represent mean values of three independent experiments.

Means significantly different from unstimulated controls. Similar results were obtained if CD3/CD19-depleted NK cells were used. The percentage of CD3⁻/CD56⁺ NK cells in all experiments was always greater 85%.
