Taking into account the subgroups of HT patients, we observed significantly higher levels of IFN-γ, IL-6, IL-12 (p40), IL1α, IL-1RA, IL-4, IL-7, and lower IL-10 concentration in the UWS of HT patients with hyposalivation compared to normal salivation HT patients (Table S9). This evidence concerns the gene IL10 and hematocrit.
