Figure 6. Licensed NK cells do not protect neonates from MCMV infection.
Ly49h−/− neonates received (a) 1 × 105 Ly49H+ NK cells sorted as either Ly49C/I+ or Ly49G2+Ly49C/I− or PBS or (b) 7.5 × 104 Ly49H+ NK cells from donors pre-depleted of Ly49C/I+ or Ly49G2+ cells in vivo or PBS and challenged with 2 × 103 pfu of MCMV. Animals were monitored daily for morbidity.
