In the blood, neutrophil mRNA expression for TLR4 was similar for term infants with RSV bronchiolitis and control infants (34.84 (2.168) and 48.16 (2.758), respectively, p = 0.625; data expressed as mean (SEM) logfold ratio of TLR mRNA to L32 mRNA). The gene discussed is TLR4; the disease is respiratory syncytial virus bronchiolitis.
