In AD-like NC/Nga mice, the PT-treated group, after st with concanavalin A for 24 h and 48 h, represented lower production of Th2 cytokines such as IL-4, IL-5, and IL-13, and a chemokine, eotaxin, than the production levels in the control group (Fig. 5). The gene discussed is IL5; the disease is Alzheimer disease.
