Table 1.

Fold change in proportion of natural killer (NK) cell subsets following interleukin (IL)-18 and IL-2 stimulations compared to fresh NK cells.

	%CD27+, CD11b−		%CD27+, CD11b+		%CD27−, CD11b+
	Wild type (WT)	IL18BPKO	WT	IL18BPKO	WT	IL18BPKO
IL-18	0.80	0.65	0.31	−0.19	−0.45	−0.59
IL-2	0.13	−0.04	0.42	0.17	−0.36	−0.10
IL-18+ IL-2	−0.50	−0.31	0.54	0.38	−0.31	−0.12

It is a color continuum from green to red. Green represents highest fold increase, while red represent lowest fold decrease.
