Concerning ILT4 mRNA expression, in HNSCC patients with tumors in the T1+T2 stage, there was a significantly higher relative ILT4 mRNA expression compared to those with tumors in the T3 stage (0.1880 ± 0.1259 vs. 0.0693 ± 0.03798, p = 0.0495, Table 6). The gene discussed is LILRB2; the disease is head and neck squamous cell carcinoma.
