For SLE patients with inactive disease (Groups 1 and 2), the expression of NOD2 were found to be significantly lower in CD8+ T (Figure 1B, p = 0.027), monocytes (Figure 1D, p = 0.002), mDCs (Figure 1E, p = 0.024), pDCs (Figure 1F, p = 0.007) in the group treated with immunosuppressants (Group 2) when compared to the non-treated group (Group 1). Here, NOD2 is linked to systemic lupus erythematosus.
