IL1B and alveolar rhabdomyosarcoma: We found no IL-1β, IFN-γ, IL-17, IL-4, and IL-10 level differences between the three groups (Figure 3A–E), while the 5-HT7 was transcribed at significantly lower levels in PBMCs of NTZ patients compared to ARMS patients and healthy subjects (p < 0.01, Figure 3F).
