However, after IL-2 stimulation and despite the preferential Ly49G2+ NK expansion, the expression of Ly49G2 does not correlate with better NK function because sorted Ly49G2+Ly49C/I- and Ly49G2-Ly49C/I+ are able to eliminate tumor cells at comparable levels suggesting that there was no an advantage of having a particular subset after strong NK activation [8]. The gene discussed is IL2; the disease is neoplasm.
