B3GAT1 and Dravet syndrome: Interestingly, CD56dimCD16+ NK cells, a subset involved in host protective immunity through cytolysis along with CD8+ T cells, from DS participants also showed an elevated frequency and expression of CD57 at BL and at week 117 in peanut-stimulated (Supplementary Fig. 2a; q = 0.059 and 0.068, respectively) and unstimulated PBMCs (Supplementary Fig. 2a; q = 0.02 and 0.01, respectively).
