IFNG and Alzheimer disease: Table 5 shows an average level of cytokine production, namely TNF-α, IFN-γ, IL-10, IL-1β, and IL-15, by uninfected (spontaneous release) and VSV-infected PBLs from AD patients and controls. The effect of EGb treatment is also presented. As shown in Table 5, VSV infection of PBLs resulted in high TNF-α but slight IL-1β and IL-15 production in both groups.
