Figure 3From: Respiratory syncytial virus infection in Fischer 344 rats is attenuated by short interfering RNA against the RSV-NS1 genesiNS1 prevents RSV-induced airway hyperresponsiveness. Rats (n = 4) were treated with siNS1 or control vector followed by RSV 24 h later. AHR in response to methacholine was measured 5 days later by whole-body plethysmography and the enhanced pause (Penh) was expressed as percentage of baseline (buffer only). Experiments were repeated twice. *p < 0.05, **p < 0.01.Back to article page
