Normal responses to poly(I:C) and HSV-1 in different leukocyte subsets. (A) Production of IFN-α, unstimulated (NS) or after 24 h of stimulation with HSV-1, in PDCs from five healthy controls (C), the patient (P), and the father (-P) and the mother (-P) of the patient. The values from two independent experiments are presented. (B) Production of IFN-λ unstimulated or after 24 h of stimulation with poly(I:C) or HSV-1 in MDMs from three healthy controls and the patient. Mean values ± SD were calculated from two independent experiments.
