KLRG1 and autoimmune pancreatitis: Interestingly, genes that are usually upregulated in late/sustained effector NK cells, such as Mki67 and Foxm1, and genes related to long-lived memory NK cells, such as Casp1, Klra6, Klra10, Ly6c1, and Klrg1, were also higher in AIP-treated NK cells (Gautier et al., 2012; Sun et al., 2009) (Figure 4C).
