On page 4014 in the 12 December 2013 issue, there is an error in the reference citations. The genetically inactivated interleukin-2 receptor γ chain (common γ chain) allele used to generate the triple knockout (TKO) mice was incorrectly attributed to DiSanto et al¹ in references 23-25, which are cited in “Materials and methods.”^2-4 The allele used to generate the TKO mice was actually obtained from Dr Kazuo Sugamura’s laboratory.⁵
