The amount of IL-23 in the supernatant from vvDD-IL-23-infected tumor cells was significantly higher than vvDD-IL-23-FG (Figure 7A), while IL-23+ cells were significantly more prevalent in vvDD-IL-23-FG-infected cells (Figure 7B), showing the successful realization of membrane association by GPI anchored to one subunit of IL-23. The gene discussed is IL37; the disease is neoplasm.
