Compared with the CON group, IL-2 and IL-6 in the HE group were significantly increased (p = 0.001, p = 0.004, Table 5), and IL-4 was significantly decreased (p = 0.004), while the contents of TNF-α and IFN-γ were significantly decreased (p = 0.017, p = 0.032). Here, TNF is linked to hereditary elliptocytosis.
