Moreover, patients with CTD-IP had an increased TLR-3 mRNA expression in comparison with sarcoidosis (mean ± SD, 2.03 ± 2 versus 0.038 ± 0.037; P = 0.002) and control subjects (mean ± SD, 2.03 ± 2 versus 0.0014 ± 0.0008; P = 0.05) (Table 5 and Figure 3). The gene discussed is TLR3; the disease is sarcoidosis.
